New Ways - Brynmawr Rubber Works
The Brynmawr factory complex, initially used for rubber manufacturing, was later used for the manufacture of Semtex explosives.
The centrepiece, the main factory area, comprised a group of nine concrete shell roof sections, grouped three by three, each 25.9metres long and 18.9metres wide. Each section, a two-way span, was slightly domed to make use of the compressive strength of the reinforced concrete which, at less than 90 mm thick, appeared wafer-thin for its dramatic clear span. The design of these concrete shell roofs is considered to be a collaboration of design and technological expertise between Ronald Jenkins and Ove himself; Jenkins had worked with Ove during their time together at JL Kier & Co, in fact it had been Ove who had given Jenkins the job at Kier’s.
The roof sections were punctuated by circular roof lights in a style popular with Modern Movement architects (like the atrium at the Boots ‘wets’ building constructed in 1932 by Owen Williams). This, together with clerestory glazing of lunettes formed by geometry of the shell sections, gave an extraordinary cathedral-like quality of natural light to the factory space. The rectangular roof sections were supported at each corner by columns a mere 4.3metres above the floor.
This gave a human scale to the vast interior, which after all had been used for assembly and production work, so that from a functional point of view an increased height would have been of no benefit. But once the manufacturing function was lost, the low headroom of the structure restricted the number of alternatives for future use, and ultimately this factor may have sealed the fate for this unique building.
Around the perimeter of the main factory area was a series of ancillary buildings covered by a multiplicity of small-scale barrel-vaulted concrete roof constructions, over poured-in-situ concrete walling.
After 50 years, the building was deemed to be unsuitable for present-day use, and was considered by local authorities to be an obstacle to progress in expanding the local economy. So in 2001, despite having been awarded a Grade II* listing, and despite the best efforts of conservationists, the complex was demolished, thus depriving future generations of a wonderful example of engineering excellence.
