BISF Homes

During the house building boom of the 1960's contractors considered numerous types of techniques. Due to the speed and haste many of these techniques have been found flawed.

The BSIF homes were constructed of walls made of steel frames with an external cladding. The flaw in these homes was the lack of corrosion protection. The steel paint coat is often found to be corroding and the steelwork is starting to rust.

Croft can provide surveys of these buildings to inspect and report on their conditions.

The BISF house is a British steel framed house, designed and produced by the British Iron and Steel Federation, and erected around the country from 1946.[1]

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.
It sponsored a solution for a permanent steel framed housing to a MoW conforming design by architect Sir Frederick Gibberd, who also designed the Howard house.[2]

The BISF is of a conventional design, with simple architectural devices of projecting window surrounds encasing Crittall Hope windows,[3] 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.[4]

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.[2]
