Technical Refurbishment

A former potteries factory in Stoke-on-Trent is set to become a centre of learning for refurbishment — after it has undergone a transformation itself. Jan-Carlos Kucharek reports.

THERE’S A PLEASING synchronicity to the idea that a new training centre devoted to refurbishment skills should itself be within a refurbished building. And not just any old building, but a rare piece of 19th century industrial heritage. The Centre of Refurbishment Excellence (CoRE), in Longton, Stoke-on-Trent, set to open early next year, has been founded in the old Enson Works, a former potteries factory dating from 1842, whose four red brick bottle kilns are a distinctive local landmark. “There used to be 400 of these bottle kilns in the Stoke-on-Trent area, now there are just 40, and we’ve got four of them,” says CoRE’s chief executive Jonathan Davis. An architect and former director of CABE, Davis has a long-standing involvement in sustainable design and is a panel member on the government’s Green Construction Board. For him, a new construction skills centre in a historic building refurbished to BREEAM “very good” standards is a poetic pairing. “The kilns look evocative, even in their run- down state,” he adds. “They’re going to make for an incredibly powerful space.” The derelict Enson Works and the adjacent American Hotel, formerly the works pub, were identified for regeneration and bought by the city

council in 2009. To create CoRE, a not-for- profit national centre of learning and skills development for the refurbishment sector, a partnership was then set up between the council, the Building Research Establishment and Stoke Studio College for Construction Excellence. This is backed by funding from the European Regional Development Fund, central government, the city council and industry partners, including energy provider E.ON. The Hub, a new-build construction

training college, opened in autumn last year. The next and final phase is the refurbishment of the Grade II-listed factory, plus piecemeal 1930s additions, into a state-of-the-art conference facility. New floors will be inserted into the building and enclose what used to be an external courtyard between the kilns, creating a demonstrators zone for innovative products, materials and systems at ground level, and a bright rooflit conference facility and reception spaces on the upper level. Light will be transferred down via glass blocks set into the concrete floor. The re-use of the bottle kilns is both

novel and ingenious. At ground floor level, where they are widest, they will act as dedicated audio visual, meeting and display spaces. From first floor, as they

narrow, they will act as stacks for the building’s natural ventilation strategy. Each has been enclosed by a square of steel beams to ensure the increased floor loads are transferred onto these instead. Contractors John Paul Construction and

Graham had a considerable task: rain had for years poured through the broken slate roof, so the whole building fabric had suffered decades of compounded decline and neglect. And as a listed building, both English Heritage and local conservation groups were keen to ensure that remediation was carried out sensitively. The first priority was to ascertain the condition of the brick facades and steel
