BISF was an association of steel producers, formed in 1934 in order to provide central planning for the industry. It was prominent in coordinating output through World War II. Post-war, BISF became key in the new Ministry of Works Emergency Factory Made housing programme.
The BISF is of a conventional design, with simple architectural devices of projecting window surrounds encasing Crittall Hope windows, and differing cladding to the upper and lower stories deal with the junction between components in an understated fashion. The main structure is of steel columns spaced to take standard metal windows between them. The central spine of the building which supports the first floor beams is carried on tubular steel columns. The framework is clad on the lower storey with rendering on metal lath. The outer cladding of the upper floor is of steel trussed sheeting fixed by angles to the steel columns. Traditional materials could be incorporated or simulated, for example a brick cladding to the lower storey, or steel sheet profiled to match timber weatherboarding to the upper. The inner cladding and the partitions are constructed of timber framing faced with plasterboard or hardboard. The upper floors are of tongue & grooved timber and the ceilings are finished with plasterboard. The outer walls and ceilings are insulated with glass quilting.
Produced by the British Steel Homes company, the BISF was a successful design in numerical terms, thanks to the backing of its trade sponsors, who could ensure a supply of steel. The BISF also benefited from a guaranteed order of 30,000 units given directly by the Government in 1941.
