Structural condition of Wimpey no-fines low-rise dwellings

Building Supplement




No-fines concrete is a non-proprietary material used extensively in England and Scotland, and to a lesser extent in Wales, for the construction of walls in dwellings. George Wimpey & Co Ltd developed a system of housing utilising this material and traditional building methods, and built in excess of 300,000 low-rise dwellings from the mid-1940s onwards. Many contracts were carried out by substituting no-fines concrete for the loadbearing masonry walls indicated in Borough Architects' plans. However, a limited number of properties were built for the private sector. Since the external walls are of cast-in-situ concrete the system is adaptable, giving many different plan configurations and types of accommodation. Numerous basic types of Wimpey No-Fines (WNF) bungalows, houses and low-rise blocks of flats and maisonettes, were produced, generally ranging in height from one to five storeys, although a few six-storey blocks were built under special supervision. The designs incorporate flat, hipped and gable roofs, porches of different designs and in some cases bay windows. The no-fines walling can also form the inner leaf of masonry-faced cavity construction.
