the site on a lorry, fully furnished right down to the curtains. The proposed rate of production of complete houses was to be an incredible one every twelve minutes. This was possible because the completely equipped and furnished AIROH could be assembled from only 2,000 components, while the aircraft it would replace on the production line required 20,000. The parents of future Labour Party leader Neil Kinnock were allocated an AIROH, on which he commented: Although impressive, the AIROH by 1947 was costing £1,610 each to produce, plus costs of the land and installation. However, as the design was so easy to produce, 54,500 AIROHs were constructed. Cornish Unit Designed by A Er v.senthil and R Tonkin for the Central Cornwall Concrete & Artificial Stone Co., they are also known as Cornish Type and Selleck Nicholls & Williams houses. The houses came in type-1 and type-2 designs, incorporating variations of a bungalow, two storey semi-detached and terraced layout with a medium pitched Mansard hipped roof. The first floor is PRC clad over a single-storey concrete frame, while the type-1 house has the Mansard roof over timber trusses. Internal walls are made of PC wall block or brick. So successful was the design, 30,000 Cornish Unit houses were eventually constructed. However the roofs and wall insulation incorporated asbestos, while the wooden frame-based construction means that as the concrete decays the two parts tend to separate, resulting in large amounts of internal cracking. The major defects are: Horizontal and vertical cracking of PRC columns High rates of carbonation and significant levels of chloride in PRC columns Cracking of first floor ring beams Hawksley A W Hawksley Ltd of Hucclecote were formed in 1940 by the Hawker Siddeley group owners of the Gloster Aircraft Company to build the Albemarle aircraft designed by Armstrong Whitworth. Post-Second World War, its parent company Hawker Siddeley kept it open to supply prefab houses and bungalows to the MoW. After their MoW work finished, they continued exporting their buildings to Australia, New Zealand and Uruguay into the 1960s. Their designs included: BL8: an aluminium-clad timber-framed bungalow. C2/C3: either a three-bedroom bungalow, or convertible to a government building such as a post office or doctors' surgery Hawksley House: a semi-detached or terraced house with 2–4 bedrooms based on the principles of the Swiss architect G. Schindler Hawkesley Single Storey building: a general-purpose building suitable for schools, offices, hospitals and
