1 00:00:14,840 --> 00:00:19,000 Out of all of Britain's cities, there's one that stands alone. 2 00:00:19,000 --> 00:00:21,120 London. 3 00:00:27,080 --> 00:00:30,760 Looking down in the capital today, what's obvious is the sheer scale 4 00:00:30,760 --> 00:00:34,360 and complexity of this sprawling metropolis. 5 00:00:36,400 --> 00:00:39,160 But how London came to look the way it does 6 00:00:39,160 --> 00:00:42,160 can also be seen from above. 7 00:00:43,240 --> 00:00:45,520 Because, 60 years ago, 8 00:00:45,520 --> 00:00:50,600 the Royal Air Force photographed the whole of London from end to end, 9 00:00:50,600 --> 00:00:56,680 and left us a unique record of a city torn apart by war. 10 00:01:02,160 --> 00:01:06,280 Now exactly the same process is being repeated, 11 00:01:06,280 --> 00:01:09,880 matching the original survey shot for shot. 12 00:01:14,240 --> 00:01:18,480 And by directly comparing London then with London now, 13 00:01:18,480 --> 00:01:21,280 we can tell the story of the greatest transformation 14 00:01:21,280 --> 00:01:23,520 in the city's history. 15 00:01:25,640 --> 00:01:28,520 It's a transformation that continues 16 00:01:28,520 --> 00:01:32,240 faster now than at any time since the war. 17 00:01:34,880 --> 00:01:38,600 This is the future face of London, 18 00:01:38,600 --> 00:01:42,720 a future that's being designed and built already. 19 00:02:05,600 --> 00:02:10,640 London's transformation began on September 7th, 1940. 20 00:02:10,640 --> 00:02:15,960 300 German bombers flew in from the east, following the line of the river. 21 00:02:18,840 --> 00:02:24,560 They arrived here at 6.45 in the evening, and looked down on their target, 22 00:02:24,560 --> 00:02:26,440 the heart of London's docks. 23 00:02:35,400 --> 00:02:38,160 It was the end of a beautiful summer's afternoon 24 00:02:38,160 --> 00:02:41,600 and London was about to change forever. 25 00:02:46,800 --> 00:02:51,280 We know exactly what happened, thanks to a series of photographs 26 00:02:51,280 --> 00:02:56,240 taken by the German planes as they dropped the first bombs on London, 27 00:02:56,240 --> 00:03:00,120 on day one of the Blitz. 28 00:03:00,120 --> 00:03:04,040 What you see in this sequence of pictures, which runs 29 00:03:04,040 --> 00:03:08,720 from Woolwich more or less to just east of the Isle of Dogs, 30 00:03:08,720 --> 00:03:12,600 are a formation of bombers. Then you see the bomb load 31 00:03:12,600 --> 00:03:15,680 being dropped by the aircraft which is carrying the camera. 32 00:03:15,680 --> 00:03:19,560 You can see also the impacts trailing across from the other aircraft, 33 00:03:19,560 --> 00:03:22,200 falling short in the river - you can see the splashes there - and the flashes 34 00:03:22,200 --> 00:03:27,640 of impact in the steelwork of the gasworks, which, of course, 35 00:03:27,640 --> 00:03:31,480 is THE major supplier of gas to London at that time. 36 00:03:31,480 --> 00:03:36,480 Subsequently, you see the impacts of the bombs hitting the river, 37 00:03:36,480 --> 00:03:40,640 and you can see the fires beginning in the docks, 38 00:03:40,640 --> 00:03:45,560 which were part of the great conflagration of 7th September. 39 00:03:48,000 --> 00:03:50,720 What you're looking at here is probably 40 00:03:50,720 --> 00:03:56,160 the most devastating change to London since the fire of London in 1666. 41 00:03:56,160 --> 00:04:00,000 You're looking at, effectively, half a millennium 42 00:04:00,000 --> 00:04:02,960 or a quarter of millennium of history about to turn, about to change. 43 00:04:04,560 --> 00:04:08,720 For five years, on and off, London was bombarded by aircraft 44 00:04:08,720 --> 00:04:13,720 and rockets, killing or injuring a quarter of a million people, 45 00:04:13,720 --> 00:04:18,320 and ripping huge holes in the fabric of the city. 46 00:04:18,320 --> 00:04:21,680 By the end of the war, it was realised that if London was to rise again, 47 00:04:21,680 --> 00:04:24,880 the first essential step on the road to reconstruction 48 00:04:24,880 --> 00:04:28,720 would be to record the damage - all of it. 49 00:04:28,720 --> 00:04:32,720 And the only way to do that was from the air. 50 00:04:40,720 --> 00:04:46,960 Between 1945 and 1949, the RAF flew more than 200 missions over London, 51 00:04:46,960 --> 00:04:50,080 shooting 50,000 individual frames, 52 00:04:50,080 --> 00:04:53,200 recording every square inch of the capital. 53 00:04:55,440 --> 00:04:58,440 Now every single one of these images 54 00:04:58,440 --> 00:05:02,280 has been scanned, and all the scans have been pieced together. 55 00:05:02,280 --> 00:05:04,920 For the first time, we have a comprehensive 56 00:05:04,920 --> 00:05:08,160 aerial picture of wartime London. 57 00:05:13,280 --> 00:05:14,920 The London you're looking at is still 58 00:05:14,920 --> 00:05:19,160 the London that had to, er, it felt it had to be self-sufficient in food. 59 00:05:19,160 --> 00:05:24,320 Virtually every open space is given over to allotments. 60 00:05:24,320 --> 00:05:26,640 Here you can see in front of the Imperial War Museum, 61 00:05:26,640 --> 00:05:30,960 you've got a really quite substantial area just given over 62 00:05:30,960 --> 00:05:33,320 to growing vegetables and so on. 63 00:05:33,320 --> 00:05:36,480 In fact, almost all open spaces in London 64 00:05:36,480 --> 00:05:39,120 were used for cultivating food. 65 00:05:43,520 --> 00:05:46,600 While the parks are full of vegetables, 66 00:05:46,600 --> 00:05:49,720 the streets appear strangely empty. 67 00:05:49,720 --> 00:05:51,640 The only vehicles in evidence 68 00:05:51,640 --> 00:05:55,560 are trams or buses or a few essential trucks. 69 00:05:57,880 --> 00:06:00,680 Barely 10% of Londoners own their own car, 70 00:06:00,680 --> 00:06:04,320 and those that do are kept off the streets by petrol rationing. 71 00:06:05,880 --> 00:06:10,240 These are the details of daily life where the bombs didn't fall. 72 00:06:10,240 --> 00:06:14,840 Where they did, the picture is rather different. 73 00:06:17,160 --> 00:06:21,240 Tens of thousands of buildings, like these riverside warehouses, 74 00:06:21,240 --> 00:06:23,680 were totally destroyed. 75 00:06:23,680 --> 00:06:27,560 If you go across the town, some parts of it are largely unaffected, 76 00:06:27,560 --> 00:06:30,640 but then when you look at it in detail, certainly with the City, 77 00:06:30,640 --> 00:06:35,120 you've got really very substantial destruction - 78 00:06:35,120 --> 00:06:38,320 whole blocks have been basically trashed. 79 00:06:38,320 --> 00:06:42,240 If you look at the area around St Paul's, for example, 80 00:06:42,240 --> 00:06:45,200 you can just see the stubs of the walls which have been left, 81 00:06:45,200 --> 00:06:49,360 preparatory to the redevelopment of this particular area. 82 00:06:49,360 --> 00:06:53,240 Effectively, it looks like the ruins of Pompeii. 83 00:06:53,240 --> 00:06:57,680 And it's not just public buildings that were hit. 84 00:06:57,680 --> 00:07:01,840 A third of London's homes had been badly damaged. 85 00:07:01,840 --> 00:07:06,400 In some areas, 85% of the housing stock had simply disappeared. 86 00:07:06,400 --> 00:07:11,680 1.5 million people had nowhere to live. 87 00:07:11,680 --> 00:07:14,440 It was clear rebuilding would take years, 88 00:07:14,440 --> 00:07:19,040 but there was a desire to do more than just rebuild. 89 00:07:19,040 --> 00:07:22,720 In the ruins of London lay an opportunity 90 00:07:22,720 --> 00:07:25,840 to completely redesign the city. 91 00:07:29,080 --> 00:07:31,560 And there was a plan to do it - 92 00:07:31,560 --> 00:07:34,200 the Abercrombie plan. 93 00:07:37,480 --> 00:07:43,040 As early as 1943, a team of designers under Lord Abercrombie 94 00:07:43,040 --> 00:07:47,960 had begun work on a new city that would rise from the ashes of the old - 95 00:07:47,960 --> 00:07:52,840 a clean-lined, open and thoroughly modern metropolis. 96 00:07:55,040 --> 00:07:57,440 London grew up without any plan or order. 97 00:07:57,440 --> 00:08:00,360 That's why there are all those bad and ugly things 98 00:08:00,360 --> 00:08:04,480 that we hope to do away with if this plan of ours is carried out. 99 00:08:05,560 --> 00:08:09,720 The plan was a top-down reordering of the entire city 100 00:08:09,720 --> 00:08:14,600 that would solve the housing crisis and produce more efficiency. 101 00:08:14,600 --> 00:08:18,240 Down here, near the boundary, would be a trading estate 102 00:08:18,240 --> 00:08:21,320 where many of the people living in the district would work. 103 00:08:23,320 --> 00:08:27,080 The city would be reorganised into zones. 104 00:08:27,080 --> 00:08:30,080 There would be zones for living, zones for working, 105 00:08:30,080 --> 00:08:32,520 zones for retail and commerce. 106 00:08:32,520 --> 00:08:35,560 All these different zones would be connected together 107 00:08:35,560 --> 00:08:39,240 by a vast network of new highways that would speed workers 108 00:08:39,240 --> 00:08:43,920 to their destinations and bring raw materials in to the working city. 109 00:08:43,920 --> 00:08:46,760 Cars and roads would be the way forward, 110 00:08:46,760 --> 00:08:50,760 as Abercrombie had seen in America. 111 00:08:50,760 --> 00:08:53,440 It's a pretty gigantic scheme, 112 00:08:53,440 --> 00:08:56,960 affecting the future of the whole of London. 113 00:08:58,520 --> 00:09:03,400 But this new city would do more than just work better than the old one. 114 00:09:03,400 --> 00:09:08,560 At its heart was a desire for space and order for its people. 115 00:09:08,560 --> 00:09:12,200 For every 1,000 inhabitants, there should be at least four acres 116 00:09:12,200 --> 00:09:17,200 of open green space - roughly twice as many as before. 117 00:09:17,200 --> 00:09:20,640 To liberate that space, much of the housing 118 00:09:20,640 --> 00:09:23,880 that hadn't already been destroyed would be demolished. 119 00:09:25,640 --> 00:09:28,400 And the people in them would be collectively rehoused 120 00:09:28,400 --> 00:09:33,760 in thousands of new apartment blocks, stacked in rows across the city. 121 00:09:33,760 --> 00:09:38,200 Just like Churchill Gardens. 122 00:09:38,200 --> 00:09:41,600 In Pimlico, not far from the Thames Embankment, 123 00:09:41,600 --> 00:09:44,160 a giant skeleton of steel is going up, 124 00:09:44,160 --> 00:09:46,280 the framework of a block of bright, modern flats 125 00:09:46,280 --> 00:09:50,680 that are to transform living conditions in this quarter of London. 126 00:09:50,680 --> 00:09:55,280 This vast housing estate near central London was the first great test 127 00:09:55,280 --> 00:09:56,920 of Abercrombie's vision. 128 00:09:58,320 --> 00:10:03,760 Brand-new homes for over 3,000 people in a single development. 129 00:10:06,280 --> 00:10:08,840 Paul Finch was one of its early inhabitants, 130 00:10:08,840 --> 00:10:12,840 now returning after 40 years to the estate he lived in as a child. 131 00:10:14,120 --> 00:10:15,720 It was quite exciting. 132 00:10:15,720 --> 00:10:20,360 I mean, we came here to go in the playgrounds and to mess about. 133 00:10:20,360 --> 00:10:23,640 Churchill Gardens was the new thing that was being built, 134 00:10:23,640 --> 00:10:28,760 and I think we just accepted it as...this is how it is. 135 00:10:30,560 --> 00:10:34,240 I had a school friend who lived in Lutyens House, 136 00:10:34,240 --> 00:10:38,680 and I can remember standing on the balcony outside his front door, 137 00:10:38,680 --> 00:10:44,080 looking down at a terrace of houses opposite that were being demolished. 138 00:10:44,080 --> 00:10:48,200 I remember his brother saying he wasn't sure why they were being demolished 139 00:10:48,200 --> 00:10:49,840 because people still lived there. 140 00:10:49,840 --> 00:10:52,320 I thought it was pretty obvious why they were knocking them down, 141 00:10:52,320 --> 00:10:55,920 cos they looked really old and dilapidated 142 00:10:55,920 --> 00:11:01,120 and kind of clapped out, compared with all these modern blocks that we now lived in 143 00:11:01,120 --> 00:11:05,320 with hot and cold running water and central heating. 144 00:11:05,320 --> 00:11:09,360 It was the idea of something modern and new and clean. 145 00:11:09,360 --> 00:11:15,400 I think when you look back at films of people who occupied new council housing, 146 00:11:15,400 --> 00:11:20,320 '40s, '50s, even '60s, what you see is people who are very, 147 00:11:20,320 --> 00:11:25,000 very happy with what they've got, and the reason for that is, 148 00:11:25,000 --> 00:11:27,640 which we all forget now, is what they came from. 149 00:11:27,640 --> 00:11:33,680 By and large, fortunately for most people, they don't have to experience 150 00:11:33,680 --> 00:11:36,720 the conditions, certainly, that their grandparents did, 151 00:11:36,720 --> 00:11:40,840 where what we would now regard as basic and essential facilities 152 00:11:40,840 --> 00:11:43,040 were simply not available. 153 00:11:45,960 --> 00:11:51,800 The late 1940s was a radical time, when Britain first turned old ideas 154 00:11:51,800 --> 00:11:55,840 of a National Health Service and a full welfare state into reality. 155 00:11:55,840 --> 00:12:00,320 It was an era that deliberately and unashamedly promised 156 00:12:00,320 --> 00:12:03,320 a brave new world for everyone. 157 00:12:08,200 --> 00:12:11,080 This is Churchill Gardens today. 158 00:12:11,080 --> 00:12:15,880 What's clear is that it's totally different to everything around it. 159 00:12:15,880 --> 00:12:19,840 If this is as far as the housing revolution got, 160 00:12:19,840 --> 00:12:23,680 what happened to the rest of Abercrombie's plan? 161 00:12:29,920 --> 00:12:32,640 The only way to find out is from the air. 162 00:12:32,640 --> 00:12:37,320 Archaeologist Chris Going has been documenting the changing face 163 00:12:37,320 --> 00:12:40,440 of London from the air for the last five years. 164 00:12:43,320 --> 00:12:46,160 We have nine frames on the second run, I think. 165 00:12:48,000 --> 00:12:52,080 By flying exactly the same route the RAF did 60 years ago 166 00:12:52,080 --> 00:12:56,360 to create the first aerial surveys, Chris hopes to create 167 00:12:56,360 --> 00:12:59,360 an identical modern survey of his own. 168 00:12:59,360 --> 00:13:03,000 What we are doing today is we are producing imagery which, 169 00:13:03,000 --> 00:13:07,360 when we compare with the 1945 material, gives you in one go, if you like, 170 00:13:07,360 --> 00:13:11,200 all the changes we've seen in the city of London, in the centre of London, 171 00:13:11,200 --> 00:13:13,240 in the last 60 years. 172 00:13:13,240 --> 00:13:14,800 It's effectively a time machine. 173 00:13:23,800 --> 00:13:27,480 By lining up the two complete sets of images, Chris is able to switch 174 00:13:27,480 --> 00:13:29,880 between the past and the present. 175 00:13:31,000 --> 00:13:34,800 Between the London Abercrombie was about to change, 176 00:13:34,800 --> 00:13:38,440 and what we actually ended up with. 177 00:13:38,440 --> 00:13:43,320 Overall, there appears to be very little difference. 178 00:13:43,320 --> 00:13:48,000 The basic matrix of roads is largely unaltered. 179 00:13:52,000 --> 00:13:55,680 There's certainly no sign of any great unified vision. 180 00:13:55,680 --> 00:13:59,200 If the population of London in the later '40s or the '50s 181 00:13:59,200 --> 00:14:06,080 could look at the London of 2008, of the 21st century, I think 182 00:14:06,080 --> 00:14:11,360 the thing they would most clearly say is how incoherent it looks. 183 00:14:12,520 --> 00:14:15,480 It does not that like the sort of envisaged city 184 00:14:15,480 --> 00:14:17,000 of the planners of the '40s and '50s. 185 00:14:20,080 --> 00:14:22,640 When it came to housing, local authorities never followed 186 00:14:22,640 --> 00:14:27,040 the Churchill Gardens model, but took to building clusters 187 00:14:27,040 --> 00:14:30,280 of high-rise tower blocks instead. 188 00:14:30,280 --> 00:14:32,640 While around them, private housing remained 189 00:14:32,640 --> 00:14:35,520 almost entirely pre-war vintage. 190 00:14:35,520 --> 00:14:39,760 Exactly the opposite of Abercrombie's vision. 191 00:14:39,760 --> 00:14:41,280 The plan to double the total area 192 00:14:41,280 --> 00:14:46,480 of green space in the city produced just one notable south London park. 193 00:14:48,320 --> 00:14:50,560 And the transport revolution that promised fast access 194 00:14:50,560 --> 00:14:54,160 along multi-lane freeways throughout the centre of the city 195 00:14:54,160 --> 00:14:56,640 never reached that far. 196 00:14:56,640 --> 00:15:01,320 Today, congestion blights the motorways running into London, 197 00:15:01,320 --> 00:15:05,640 because the centre is just the same old maze of streets 198 00:15:05,640 --> 00:15:07,560 from before the war. 199 00:15:08,560 --> 00:15:12,160 And in the heart of the city, where a great modernist capital was meant 200 00:15:12,160 --> 00:15:14,120 to stretch along the Thames, 201 00:15:14,120 --> 00:15:17,880 only the centrepiece, the Royal Festival Hall, was ever built. 202 00:15:19,400 --> 00:15:22,560 Ultimately, Abercrombie failed. 203 00:15:22,560 --> 00:15:27,920 But his failure should be judged in the light of history, 204 00:15:27,920 --> 00:15:31,760 because London had tried this kind of thing before. 205 00:15:33,960 --> 00:15:38,280 300 years earlier, after the great fire, Christopher Wren 206 00:15:38,280 --> 00:15:42,480 came up with a grand new vision for London. 207 00:15:46,800 --> 00:15:51,000 A formal European capital that would radiate out 208 00:15:51,000 --> 00:15:54,240 from the glorious centrepiece of St Paul's Cathedral. 209 00:15:56,080 --> 00:16:02,720 But just as with Abercrombie, the centrepiece was all that got built. 210 00:16:02,720 --> 00:16:05,880 Neither man managed to get the money or the political backing 211 00:16:05,880 --> 00:16:09,280 to tear down the city and start again. 212 00:16:09,280 --> 00:16:13,840 Wren had a big vision for London, which he was not able to fulfil 213 00:16:13,840 --> 00:16:17,760 because of the competing interests of people who, basically, just wanted 214 00:16:17,760 --> 00:16:19,520 to get back to what it was like before. 215 00:16:21,040 --> 00:16:24,360 After the Second World War, Abercrombie had a plan. 216 00:16:24,360 --> 00:16:27,960 But London is resistant to grand plans. 217 00:16:29,800 --> 00:16:33,680 Yet London has been transformed all the same. 218 00:16:33,680 --> 00:16:36,240 From the city of the 1940s 219 00:16:36,240 --> 00:16:40,240 to the city of today, there's a world of difference. 220 00:16:40,240 --> 00:16:43,360 And far from following any central plan, 221 00:16:43,360 --> 00:16:48,880 it's largely the result of barely controlled economic forces. 222 00:16:48,880 --> 00:16:51,440 What London responds to is trade, 223 00:16:51,440 --> 00:16:56,920 commerce, money, markets, prosperity and movement. 224 00:16:56,920 --> 00:17:01,400 And in the end, what has made London is precisely those things. 225 00:17:06,320 --> 00:17:10,280 Money changed London in ways no-one in the 1940s 226 00:17:10,280 --> 00:17:16,240 could ever have imagined, because London changed the way it made money, 227 00:17:16,240 --> 00:17:19,560 and nowhere shows this more clearly than here. 228 00:17:19,560 --> 00:17:25,080 The modern, geometric blocks of Canary Wharf now hide what used 229 00:17:25,080 --> 00:17:27,760 to power this city - the docks. 230 00:17:29,960 --> 00:17:31,600 Since Roman times, 231 00:17:31,600 --> 00:17:36,160 London's docks had been the engine room of the city's economy. 232 00:17:36,160 --> 00:17:41,600 Stretching for ten miles along the Thames, by the late 1930s, 233 00:17:41,600 --> 00:17:45,520 the port of London had grown to be the largest in the world. 234 00:17:45,520 --> 00:17:50,520 This was where the whole of the British Empire brought its goods to trade, 235 00:17:50,520 --> 00:17:56,800 which is why, when the war ended, the docks were rebuilt immediately. 236 00:17:56,800 --> 00:18:00,920 Dock workers had to make do with living in prefabs. 237 00:18:04,160 --> 00:18:07,800 And for 30 years after the war, life in the docks went on, more or less, 238 00:18:07,800 --> 00:18:12,880 as it had before, and looked set to continue, unchanged, forever. 239 00:18:12,880 --> 00:18:16,440 What they didn't see coming was this. 240 00:18:16,440 --> 00:18:20,720 By the 1970s, what the world's economy demanded for shipping 241 00:18:20,720 --> 00:18:25,680 was giant bulk containers carried on giant container ships 242 00:18:25,680 --> 00:18:30,920 that could only be processed in giant container ports, like Felixstowe. 243 00:18:32,160 --> 00:18:35,000 None of which would fit into London's tight, narrow river, 244 00:18:35,000 --> 00:18:38,720 with its densely packed, labour-intensive docks. 245 00:18:43,440 --> 00:18:47,400 As the last dock facilities finally closed at the end of the '70s, 246 00:18:47,400 --> 00:18:50,040 the remaining 10,000 jobs went with them, 247 00:18:50,040 --> 00:18:56,280 leaving behind a vast, derelict wasteland. 248 00:19:04,040 --> 00:19:08,360 When the docks became redundant in the early 1970s, 249 00:19:08,360 --> 00:19:12,800 there was a great think about what to do with this area. 250 00:19:12,800 --> 00:19:16,800 There was a public sector body set up, which was going nowhere, 251 00:19:16,800 --> 00:19:19,760 and then suddenly the hand of commerce intervened, 252 00:19:19,760 --> 00:19:21,760 because people who were having a problem 253 00:19:21,760 --> 00:19:25,080 getting sufficient office space in the City of London, 254 00:19:25,080 --> 00:19:28,240 at the sort of rents they thought they should be paying, 255 00:19:28,240 --> 00:19:32,280 suddenly looked at Canary Wharf and thought, "Why don't we do it down there?" 256 00:19:32,280 --> 00:19:35,920 And this great private sector experiment began. 257 00:19:37,560 --> 00:19:42,080 This was the first time in hundreds of years that eight square miles 258 00:19:42,080 --> 00:19:47,400 of prime building land had appeared so close to the centre of London. 259 00:19:48,760 --> 00:19:54,720 There was an unrivalled opportunity to think through 260 00:19:54,720 --> 00:19:58,640 what the whole development would be over its entire lifespan 261 00:19:58,640 --> 00:20:02,000 and to plan for that right from day one. 262 00:20:02,000 --> 00:20:04,320 This was very unusual. 263 00:20:06,920 --> 00:20:10,160 By the end of the '80s, the wasteland had become 264 00:20:10,160 --> 00:20:12,880 the biggest building site in the world. 265 00:20:12,880 --> 00:20:17,640 I remember first arriving here and seeing a forest of tower cranes 266 00:20:17,640 --> 00:20:21,360 and very little else. We recognised that at the beginning 267 00:20:21,360 --> 00:20:26,120 we would have to build a certain number of buildings to start with 268 00:20:26,120 --> 00:20:29,800 just to get people to move here and to realise 269 00:20:29,800 --> 00:20:34,240 that this wasn't just an office building in the middle of nowhere, but a place, 270 00:20:34,240 --> 00:20:40,480 and I think the risk was in creating that first group of buildings 271 00:20:40,480 --> 00:20:44,040 and expecting that companies would actually move here as a result. 272 00:20:46,360 --> 00:20:51,920 Prospective companies were lured by huge Government incentives, 273 00:20:51,920 --> 00:20:56,280 effectively giving the land to anyone who'd build on it, 274 00:20:56,280 --> 00:20:58,400 as well as paying for new transport links 275 00:20:58,400 --> 00:21:00,440 to bring City workers to their new offices. 276 00:21:03,000 --> 00:21:05,560 At first, all went swimmingly. 277 00:21:08,600 --> 00:21:12,400 Then the country was hit by recession and, suddenly, 278 00:21:12,400 --> 00:21:17,520 no-one would take the risk of relocation to a giant building site. 279 00:21:17,520 --> 00:21:21,440 The first Docklands developers went into receivership. 280 00:21:29,280 --> 00:21:32,400 When the economy did finally turn round, 281 00:21:32,400 --> 00:21:36,760 the developers had their master plan waiting. 282 00:21:36,760 --> 00:21:38,880 And the result was this - 283 00:21:38,880 --> 00:21:43,840 what's often been likened to a piece of Manhattan, dropped from the sky. 284 00:21:46,360 --> 00:21:48,560 People say, when they're in Canary Wharf, 285 00:21:48,560 --> 00:21:50,320 "This doesn't quite feel like London," 286 00:21:50,320 --> 00:21:54,760 and the reason why it doesn't feel like London is because it isn't like London. 287 00:21:54,760 --> 00:21:57,280 And the reason it's not like London 288 00:21:57,280 --> 00:22:02,640 is because it was master-planned by American architects and planners, 289 00:22:02,640 --> 00:22:08,120 working in a tradition of a grid, working, right from the beginning, 290 00:22:08,120 --> 00:22:11,680 with the idea that you should integrate transport 291 00:22:11,680 --> 00:22:16,440 and employment in one seamless way, which it does extremely successfully. 292 00:22:16,440 --> 00:22:19,840 In fact, the only problem it has is maybe it's a little bit too successful, 293 00:22:19,840 --> 00:22:22,800 but that's better than not being successful enough. 294 00:22:22,800 --> 00:22:28,400 Where 100,000 men once handled cargo at the end of the war, 295 00:22:28,400 --> 00:22:32,520 just as many people now earn a living in financial services. 296 00:22:35,560 --> 00:22:40,120 By the turn of the century, this alien-looking invader 297 00:22:40,120 --> 00:22:45,160 had become a serious rival to London's old financial centre, the Square Mile. 298 00:22:45,160 --> 00:22:49,040 The old City was bound to respond to the challenge. 299 00:22:50,600 --> 00:22:52,120 And it has. 300 00:23:07,760 --> 00:23:14,080 This is the Square Mile today, in the midst of a colossal building boom, 301 00:23:14,080 --> 00:23:18,640 the most obvious feature of which is that its jumble of structures 302 00:23:18,640 --> 00:23:22,640 looks very different to the organised blocks of Canary Wharf. 303 00:23:22,640 --> 00:23:27,920 And that's because new buildings here don't stand on a regular grid. 304 00:23:27,920 --> 00:23:31,880 They stand on a street plan that hasn't changed radically 305 00:23:31,880 --> 00:23:33,360 in 1,000 years. 306 00:23:33,360 --> 00:23:36,240 The streets of London, which is really the geography of London, 307 00:23:36,240 --> 00:23:37,760 especially the heart of London, 308 00:23:37,760 --> 00:23:42,800 is rooted in medieval history. They're narrow, and, basically, 309 00:23:42,800 --> 00:23:45,080 they're for horses and people who are walking. 310 00:23:45,080 --> 00:23:48,760 We've kept to that in most areas in the centre. 311 00:23:48,760 --> 00:23:51,160 This gives some pretty big constraints for - 312 00:23:51,160 --> 00:23:55,400 1,000 years later, shall we say - where movement has completely changed. 313 00:23:55,400 --> 00:24:00,200 We don't have the classical streets that you see in Paris, 314 00:24:00,200 --> 00:24:02,640 or the grid forms we see in New York. 315 00:24:02,640 --> 00:24:06,520 We have grown very much ad hoc, piece by piece. 316 00:24:06,520 --> 00:24:12,400 The name of the game here is to squeeze bigger and bigger offices 317 00:24:12,400 --> 00:24:14,840 into these irregular spaces. 318 00:24:14,840 --> 00:24:18,920 One of the best examples of how this can be done is the Gherkin, 319 00:24:18,920 --> 00:24:22,960 which cleverly creates more space in the air than it has on the ground, 320 00:24:22,960 --> 00:24:24,320 with its bulging shape. 321 00:24:28,640 --> 00:24:31,880 Others are twisted into a variety of strange forms 322 00:24:31,880 --> 00:24:35,000 to maximise the limited space they have. 323 00:24:35,000 --> 00:24:38,240 Architecture has developed out of constraints. 324 00:24:38,240 --> 00:24:42,160 The real art of architecture is getting a constraint - you can't avoid them - 325 00:24:42,160 --> 00:24:45,640 and then turning them upside down and seeing how they fit. 326 00:24:52,240 --> 00:24:57,640 But there's more in the City than just a street plan to challenge an architect. 327 00:24:57,640 --> 00:25:00,080 There are dozens of ancient buildings, 328 00:25:00,080 --> 00:25:06,320 none greater than the looming presence of St Paul's Cathedral. 329 00:25:06,320 --> 00:25:09,640 For 350 years, St Paul's has been the jewel 330 00:25:09,640 --> 00:25:11,640 in the architectural crown of the City, 331 00:25:11,640 --> 00:25:16,760 and is now so venerated that even the views of it, 332 00:25:16,760 --> 00:25:21,000 from miles across the city, are protected by planning laws. 333 00:25:23,080 --> 00:25:27,960 Fortunately, there's a new visual tool to help architects avoid the problem. 334 00:25:29,200 --> 00:25:34,440 This picture, and thousands like it, form part of a giant 3-D graphic model 335 00:25:34,440 --> 00:25:38,000 showing the whole city, with St Paul's at its heart. 336 00:25:39,920 --> 00:25:41,960 These are the sight lines, 337 00:25:41,960 --> 00:25:45,560 where the greatest restrictions on building are enforced. 338 00:25:47,640 --> 00:25:51,080 It was in one of these corridors that Richard Rogers was asked 339 00:25:51,080 --> 00:25:52,920 by developers British Land 340 00:25:52,920 --> 00:25:56,880 to create what would be the tallest office block in the City of London, 341 00:25:56,880 --> 00:26:00,600 a structure that would stand right behind the cathedral. 342 00:26:00,600 --> 00:26:03,920 The only way to get out of the view is to slope backwards, out of the views. 343 00:26:03,920 --> 00:26:07,440 So when you're looking, specifically, from the west side of London, 344 00:26:07,440 --> 00:26:11,400 you would block St Paul's if the building was straight up. 345 00:26:11,400 --> 00:26:13,200 So we move it sideways 346 00:26:13,200 --> 00:26:18,960 and you get a sort of A-shape, or, as it's been termed, a Cheese Grater. 347 00:26:24,800 --> 00:26:27,280 This is it - the Cheese Grater, 348 00:26:27,280 --> 00:26:33,960 at 122 Leadenhall - a 225-metre, 48-storey office block, 349 00:26:33,960 --> 00:26:39,240 London's newest skyscraper, as it will look very soon. 350 00:26:42,920 --> 00:26:49,560 What's made this possible is the creative power of 3-D graphics. 351 00:26:49,560 --> 00:26:52,520 Rogers' design partner, Cityscape, 352 00:26:52,520 --> 00:26:55,600 built a virtual 3-D model of the whole of the City of London 353 00:26:55,600 --> 00:26:57,640 and then plonked into it 354 00:26:57,640 --> 00:27:00,720 a millimetre-perfect vision of the Leadenhall Building, 355 00:27:00,720 --> 00:27:03,600 proving, before the first stone was ever laid, 356 00:27:03,600 --> 00:27:06,680 that it would fit into the existing city. 357 00:27:06,680 --> 00:27:08,680 And the Leadenhall Building 358 00:27:08,680 --> 00:27:12,520 won't be the last to make use of this new technology. 359 00:27:14,280 --> 00:27:16,960 Each one of these structures 360 00:27:16,960 --> 00:27:22,200 is set to "grace" the skyline in the next few years. 361 00:27:22,200 --> 00:27:26,040 There must be change, always change, 362 00:27:26,040 --> 00:27:30,280 as one season, or one generation, follows another. 363 00:27:30,280 --> 00:27:35,480 When Lord Abercrombie first proposed building a new city after the war, 364 00:27:35,480 --> 00:27:38,120 it was assumed it could only be done 365 00:27:38,120 --> 00:27:41,680 by tearing down and starting again, with a great plan. 366 00:27:43,520 --> 00:27:47,840 In the late 1940s, people believed in planning, 367 00:27:47,840 --> 00:27:51,280 and they believed that planning was going to create a better London, 368 00:27:51,280 --> 00:27:53,120 a better Britain and a better world. 369 00:27:53,120 --> 00:27:59,960 London did change, but not through grand designs or utopian ideals, 370 00:27:59,960 --> 00:28:05,160 but by commerce and opportunity and the creative energy of its people. 371 00:28:05,160 --> 00:28:07,360 Today, London is the greatest capital in the world. 372 00:28:07,360 --> 00:28:09,000 The only competition is New York. 373 00:28:09,000 --> 00:28:10,400 So it's a big change, 374 00:28:10,400 --> 00:28:12,600 not only in economics, but in social as well, 375 00:28:12,600 --> 00:28:15,080 in the vitality of the city. So that's fantastic. 376 00:28:15,080 --> 00:28:20,400 And it comes out of that marriage of 1,000 years between old and new, 377 00:28:20,400 --> 00:28:22,400 the more formal - 378 00:28:22,400 --> 00:28:25,120 the churches, the town halls, city halls, and so on - 379 00:28:25,120 --> 00:28:28,440 and the wonderful medieval structures and the modern buildings. 380 00:28:28,440 --> 00:28:30,360 So they all sit together. 381 00:28:30,360 --> 00:28:33,000 Not everyone loves the way London is changing, 382 00:28:33,000 --> 00:28:37,040 but London is simply doing what London always has - 383 00:28:37,040 --> 00:28:38,480 making money, 384 00:28:38,480 --> 00:28:41,080 making compromises, 385 00:28:41,080 --> 00:28:43,320 evolving. 386 00:28:51,640 --> 00:28:54,720 Subtitles by Red Bee Media Ltd 387 00:28:54,720 --> 00:28:57,680 E-mail subtitling@bbc.co.uk
