Since the collapse of Sheffield's famous steel industry, regeneration initiatives have come and gone with little success. So, what are the chances that the latest, Sheffield One, will rub the rust off the city's image?
Crane spotters could have a field day in Sheffield. More are visible in the city centre today than have been seen for several decades, and most of these are at work bringing back housing to the heart of the city. There are more than 1000 dwellings under construction in the centre, according to recent research by property consultant Knight Frank. Other even more ambitious development plans have recently been unveiled 鈥 a 拢300m retail quarter, a 拢100m advanced technology business park called E-campus, and a 拢20m yuppie enclave containing a four-star hotel, luxury flats, fine restaurants and a health centre, all converted out of a pair of Victorian grammar schools.

To stimulate and steer these developments, Sheffield boasts one of the UK's three trailblazing urban regeneration companies, Sheffield One, as recommended by Lord Rogers' urban taskforce in its Towards an Urban Renaissance report. Now in the second year of its 10-year programme, Sheffield One is unveiling building projects first outlined in a masterplan completed in February 2001 by American urban design consultant Koetter Kim.

All the signs are that Sheffield city centre is following in the acclaimed regeneration footsteps of northern cities such as Manchester, Leeds and Newcastle. Nobody doubts that radical regeneration is crucial for Sheffield to create a sustainable modern economy after the collapse of the steel industry in the mid-1980s, which has left unemployment hovering at 8-9%.

In order to meet this need, Sheffield One has prioritised six regeneration projects for the city centre alone. These could cost up to 拢600m, according to the company's director of projects, Andy Topley. He calculates that, between 2001 and 2008, about 拢100m of public funding has been earmarked for the area from the European Union's Objective One renewal fund, the DTLR's single regeneration budget, the local transport plan and lottery funds.

But a more pessimistic note is sounded by Gwyn Rowley of Sheffield University's geography department, who dismisses Sheffield One as "a lot of huff and puff". He argues that Sheffield is afflicted by a deeper economic malaise than Manchester, Leeds and Newcastle and that this could mean that the current line-up of development proposals fail to deliver economic prosperity. For a start, he points out, despite being England's fifth largest city with a population of nearly 500,000, Sheffield has never had the employment-generating status of a regional centre. Second, the giant 1980s Meadowhall shopping centre in the Don Valley has established a region-wide clientele of up to 10 million shoppers, who would have little incentive to visit Sheffield city centre even if its shopping was regenerated. Third, despite the supertram system, Sheffield lies off primary rail and road routes, and its transport network is poorly integrated. Finally, Rowley questions how new city centre offices, shops and bars are supposed to benefit Sheffield's poorest communities in the east, where unemployment has risen to 22%, shops have closed down and education is substandard.

Sheffield has had its share of regeneration initiatives before. In the 1980s, an urban development corporation and enterprise zone were set up to redevelop the redundant steelworks in the adjacent Don Valley. In 1991, it staged the World Student Games, for which it built the Don Valley Stadium, Ponds Forge swimming complex and other sports facilities. In 1995, it secured lottery funding for the 拢15m National Centre for Popular Music.

The Sheffield Development Corporation may have replaced heavy steelworks with light industry and warehousing, but these provided relatively little employment, argues Rowley. The World Student Games left the city some 拢5m in the red, and the pop music centre bombed spectacularly in 2000 within a year of opening 鈥 it is currently less than half occupied as a rock venue while a business plan is being prepared for a new use.

So what is different this time round? Well, unlike the development corporation, which was "sent like an army of stormtroopers into a foreign country", according to Simon Ogden, the council's chief city-centre planner. By contrast, Sheffield One is by all accounts a smoothly co-ordinated partnership between the council, regional development agency Yorkshire Forward and English Partnerships. "I've never known a time when all the agencies in Sheffield are so committed to working together," says Topley, who worked for the old development corporation.

Also, Sheffield One is pursuing a mixed-use, high-density, urban regeneration policy that accords closely with Lord Roger's urban renaissance agenda. In contrast with Meadowhall, Sheffield One concentrates regeneration in the heart of the city and avoids putting all its investment eggs in one large single-use basket. Both of these suggest a higher level of sustainability than previous initiatives.

The main challenges ahead, according to Topley, are to solve complex matters of land assembly in the city centre to make way for the proposed retail quarter. "Land ownership is very fragmented, with scores of freeholders," he says. "At first we are trying to purchase by negotiation, with compulsory purchase orders following on after planning approval, which should be spring next year. There's a huge amount of paperwork involved in the land assembly, and it doesn't sit happily with the funding regimes, such as Objective One, which runs out in six years, and the single regeneration budget."

"There's also great complexity in the funding regimes themselves," he continues. "At times it all seems too complex and at odds with our regeneration timetable."

Even more complications have been introduced by English Heritage and CABE, which at a meeting last month, persuaded Sheffield One and the city council to base their regeneration plans on the conservation of its "steel city" heritage. This strategy involves "a landscape characterisation study", the first stage of which was the publication last December of a 54-page book on the buildings of the Sheffield metal trades. "The next stage is to decide whether to extend the conservation area, which covers most of central Sheffield, and whether to list more buildings on a thematic basis," says David Fraser, director of EH's northern region. As an incentive, EH and the Heritage Lottery Fund have offered conservation grants worth more than 拢2m.

All these bureaucratic hurdles to development in Sheffield city centre have put off contractor Taylor Woodrow, which headed the consortium for the 拢51m first phase the Heart of the City PFI (see "Sheffield One's big six", page 33) completed last year but has not hung around for the second phase.

Other developers and housebuilders have taken a more optimistic view. They include such big-time property developers as Hammerson for the retail quarter, Teesland/GMIR joint venture for the E-campus, and Ask Developments of Manchester for the Leopold Street development. National housebuilders, such as Persimmon, Wilson Bowden, Bellway and Gleeson Homes, are also investing in sizeable new schemes in the area.

Not surprisingly, national contractor Gleeson is streets ahead in its home city. "We have three contracts worth 拢50m in total for residential projects on a single half-mile stretch of West Street alone," says the northern construction division's business development director, David Jones. "We are seeing very strong potential growth for the city centre."

No doubt to the delight of the crane spotter out there.

Class distinction: Sheffield鈥檚 school-building bonanza

Sheffield council is five years into one of the UK鈥檚 largest school-building programmes. Over the past five years, some 拢140m has been spent on school buildings, and last November another 10-year, 拢230m investment programme was unveiled. By 2012, virtually every school in the city will have been renovated or totally rebuilt. This puts school-building at the top of the city鈥檚 regeneration projects, on a par with Hammerson鈥檚 proposed 拢300m retail development in the city centre. It is not just the scale that marks out Sheffield鈥檚 school construction programme. The council is also pioneering new forms of procurement, principally PFI, and is one of 12 local authorities experimenting with new school designs as part of the Department for Education and Skills鈥 Classroom of the Future initiative. So important does the council regard its school-building programme that it has seconded the former city architect, Andy Beard, to head its education planning and premises service. Beard has also been appointed by CABE as an enabler to improve the quality of PFI design, and has enlisted staff members of Sheffield University school of architecture to design his four Classroom of the Future projects. Beard鈥檚 old development department at the council, Sheffield Design & Property, is responsible for roughly half the school designs. 鈥淲ith in-house design, we can learn from previous projects,鈥 he says. Beard鈥檚 department must juggle with a bewildering array of 13 government funding initiatives. Not surprisingly, this leads to several procurement modes. PFI accounts for about 50% of the investment programme, but is targeted exclusively at the larger new-build projects. Most other projects are traditionally procured, with some design-and-build. In addition, the council has set up two partnering contracts, for a secondary school with Henry Boot and for three primary schools with Willmott Dixon. As a rule, traditional construction techniques are adopted. 鈥淲e have not gone down the system-building route,鈥 he says. 鈥淭he hilly sites are really constraining, and many projects are intricate adaptations and extensions.鈥 Last September, one of the DfES鈥 first pilot PFI projects, a 拢50m package of four secondary and one primary schools, was completed by Interserve (formerly Tilbury Douglas) with GHM Rock Townsend as architect. 鈥淭he phenomenal size and speed of a PFI project presents a temptation for the design team to cut corners,鈥 he says. 鈥淪o the detailing has suffered. But there are pluses, too: durable materials have been used because the contract is to maintain the buildings for 25 years.鈥 Beard鈥檚 department is now embarking on its third PFI project. The four Classrooms of the Future have been approached from opposite direction. Each is a small school extension designed as a one-off to provide an inspirational environment for pupils. One of these is aimed at supporting new ways of learning, and the other three set out to integrate with the surrounding natural environment.
