Angled against a cold breeze, John Thompson stands on the pedestrian bridge spanning the dock between the Excel Exhibition Centre in London Docklands and the residential area of West Silvertown. He鈥檚 looking west towards the Millennium Dome, Canary Wharf, and the jumble of chemical factories that form the north Greenwich skyline. But in his mind鈥檚 eye, he鈥檚 seeing a landscape that was never built.

He is visualising a bridge of houses and shops stretching across the dock like a latter-day version of the medieval London Bridge. Moored yachts make a colourful display against the awnings and umbrellas of cafes and bars. The sheltered basin beyond the bridge is perfect for wind-surfing or canoeing. 鈥淚magine it. Instead of all that crap in the background, you鈥檇 have a focused vision,鈥� he says, shaking his head as if he can鈥檛 quite believe what he isn鈥檛 seeing. 鈥淚t would have reconnected the two banks and brought more visibility to the site.鈥�

The idea for an inhabited bridge emerged from a pioneering exercise in community consultation held back in 1993. Silvertown contains the only sugar refinery in the UK, and the largest in the world. However, it depended on the Royal Docks for its economic vitality. When they closed, the area went into decline, and even after their death, the docks still dominate the area, which is a kind of crescent-shaped island between the basins of the Albert, Victoria and George V docks and the Thames.

The regeneration plan was worked out at the 鈥淲est Silvertown Planning for Real鈥� weekend in 1993, an event initiated by the Prince

Charles-backed Urban Villages Forum and chaired by Thompson, who was then a partner in Hunt Thompson Associates. Twelve years later, Regenerate took Thompson back to West Silvertown to see how the scheme that eventually took shape measures up against the plans drawn up on that weekend.

During the weekend, participants told the team about a long-demolished dock wall that had once created a tidal basin at the dock鈥檚 western end. 鈥淟ocal history and knowledge gave us the idea. People remembered the dock wall as a route and an important piece of heritage,鈥� Thompson recalls. After the event, Hunt Thompson teamed up with a consortium led by developer Trevor Osborne and housebuilder St George. They calculated that the bridge was commercially viable if it utilised the existing wall footings.

But the community had no powers to ensure that the team appointed by the London Docklands Development Corporation took account of their wishes. In the event, the LDDC preferred the less risky vision proposed by George Wimpey and architect Tibbalds Monro. 鈥淚t was a really bad decision,鈥� Thompson says. 鈥淚t would鈥檝e raised the scheme鈥檚 commercial value.鈥�

Renamed Britannia Village, the area now has about 800 private sector homes and 140 rented by the Peabody Trust and 95 by East Thames Housing Group, plus a new primary school. They are connected to east London by a shiny silver footbridge, its metal deck raised above the water to allow access for the boats that are conspicuous by their absence.

The need to negotiate a none-too-clean lift in order to cross the bridge seems to emphasise that the area is a semi-island cut off from the rest of Docklands 鈥� as does the sign announcing that the bridge is closed between 1am and 5am every night. In the lift, Thompson thrusts the report from the planning weekend at a fellow passenger, explaining the inhabited bridge concept with urgency and enthusiasm. City worker and private renter David Enzor, 23, nods, especially when Thompson mentions bars. 鈥淭hat sounds great,鈥� he says. 鈥淚 always have to run back from a night out because this bridge shuts at one o鈥檆lock.鈥�

On the bridge, Thompson compares his original sketches with the view in front of him. Apart from the missing bridge, there is one more obvious difference. Britannia Village is a medium-rise development, as uniform in height as the low-slung Excel exhibition centre it faces. But in the sketches, two tower blocks stand at the western end, providing an anchor-point and a visual link to the towers of Canary Wharf.

Thompson has to wrestle with the irony that the planning event demonstrated bold thinking over the inhabited bridge, but proved reactionary over the fate of two council-owned high-rises, Barnwood Court. At the event, the dilapidated tower blocks were used as target practice for local people firing broadsides at their council. 鈥淧eople felt stranded, and so they blamed it on the building, not the housing policy,鈥� he says. 鈥淣owadays there are plenty of examples of high-rise make-overs, but Wimpey thought they were vertical slums that would pull down the value of the estate. In fact, they鈥檇 have been extremely valuable, and added to the density, mix and vibrancy of the area.鈥�

The bridge lands in the lee of a crescent-shaped block of flats with shop units at ground level. With its red-brick facade and glazed-in balconies, it鈥檚 an attractive-looking building in a prime location. Thompson is surprised to see the Peabody Trust nameplate on the intercom, indicating that these are social rented flats and an early example of pepperpotting.

The building is a text-book example of a mixed-use development, but its mini-market and newsagents aren鈥檛 exactly bustling, and one large corner unit has been taken by a local skills and training agency. As Thompson points out, the text book didn鈥檛 include equations on how many residents were needed to support new businesses, and how many businesses were needed to draw in outside visitors. 鈥淚t鈥檚 a reminder of how many people you need to generate activity for shops, cafes and businesses. You鈥檙e trapped between two bodies of water and don鈥檛 have many people to play with.鈥� Another large unit is taken by an estate agent, which does seem to have a steady trickle of trade. Heike Merlitz, a German GP working in Poplar and renting in another part of Docklands, is on her way to find out about flats for sale in the village. 鈥淚 think the area is quite nice, but what I don鈥檛 like is when the lifts are vandalised,鈥� she says.

As a born-again urbanist, I鈥檓 now looking at the masterplan with a critical eye

If she does move to West Silvertown, she will be joining an international community. Thompson had hoped to speak to more of today鈥檚 residents and meet someone who had lived in this area before it was rebuilt. But he comes up against a language barrier: a young woman pushing a buggy speaks no English at all, and two lads washing their car are Lithuanian renters who comment that 鈥渋t鈥檚 a nice peaceful area鈥�.

As we walk around, it鈥檚 clear that the layout of West Silvertown is reasonably faithful to the sketches Hunt Thompson produced after the community planning event. In the masterplan and in real life, the development has been massed around the middle of the dock. Along the dockside, generous spacing and courtyards between blocks maximise views of the water. And the dock-side cranes give the area a sense of identity. 鈥淭hey鈥檙e fabulous, marching down the quayside like something from The War of the Worlds,鈥� Thompson says.

Among the residents that Thompson does speak to, the water-side location is the area鈥檚 most popular feature. 鈥淲hen you look out of the window [of the apartment blocks] you can鈥檛 see the dock, just the water. At night, when Excel鈥檚 lit up, it looks quite pretty,鈥� says David Enzor. 鈥淚t鈥檚 nice being by the water, it feels quite secure. And it鈥檚 peaceful 鈥� a little too peaceful,鈥� says New Zealander Mary Anderson. The views are also mentioned by Brazilian tenant Flavio de Souza, although he adds that 鈥渁 gym would be useful鈥�.

Further into the scheme, Thompson is brought up short. So far, the visit has been an exercise in comparing and contrasting what was built with what was planned. But in Evelyn Road, he comes face to face with the deficiencies of that masterplan. 鈥淭he street鈥檚 far too wide 鈥� today we would tighten it up a bit. It doesn鈥檛 feel like London. Look at how many cars are coming down this street!鈥� he asks, as one solitary Ford Focus snakes its way around traffic-calming bollards. 鈥淲ho designed it? An urbanist or a traffic engineer? It would have a more urban feel if we鈥檇 designed it today. It would have had a tighter urban grain and we鈥檇 minimise the space given over to the car.鈥�

Beyond the avenue, apartment blocks give way to terraced housing arranged around open spaces. But Thompson is concerned that the architectural identity evident at the dockside hasn鈥檛 reached this part of the site. 鈥淚t lacks coherence in the urban coding. It would have helped to have a more rigorous spatial language. It鈥檚 decoration over design,鈥� he argues. But he concedes that he鈥檚 talking with the benefit of hindsight, PPG3, and a decade鈥檚 worth of debate on place-making. 鈥淭oday we鈥檇 have given it a more urban solution and higher density to give it a bit more life. As a born-again urbanist, I鈥檓 now looking at it with a critical eye. At the time, I was a community planner.鈥�

So does the community planner think that Britannia Village can be judged a success? Thompson thinks for a while before giving a measured response. 鈥淧eople wanted decent housing, a new school, and a community. I think the mix and concept is as it was. It鈥檚 a good outcome for where we were at the time.鈥�
