Wimpey no-fines house

The Wimpey No-fines House was a construction method and series of house designs produced by the George Wimpey company and intended for mass-production of social housing for families, developed under the Ministry of Works post-World War II Emergency Factory Made programme. "No-fines" refers to the type of concrete used - concrete with no fine aggregates.^[1]

Background

A rapid increase in the birth rate compounded by the loss of city centre housing during the Blitz meant demand for accommodation in post-World War II Britain was particularly intense. Skilled labour and materials were in short supply and commanded high prices. Local government around the country commissioned large building projects to meet the demand, and innovative designs like the no-fines house gave private contractors like George Wimpey a compelling proposition to give the state. Wimpey's houses could be produced rapidly and cheaply, minimising the need for in-demand skills like bricklaying.

An example of no-fines concrete construction, Wimpey's design was particularly successful and many thousands were built in the late 1940s and early 1950s. In the late 1950s, the emphasis for public housing moved to high-rise accommodation.

Design

Designed to a Ministry of Works specification, no-fines houses focused on functional design for family life. There are only a handful of variations in the houses built, and typically all variants are found on each estate:

• 2-bedroom semi-detached and terraced houses
• 3-bedroom semi-detached houses of which there are two styles
  • a gable end at both sides of the house
  • a sloping hip end at both sides of the house
• Short terraces of 4 or 6 houses, each of which either
  • 3-bedroom end or mid-terrace
  • 4-bedroom mid-terrace with integral ginnel for rear access

Many examples are accompanied by a single-storey brick-built outbuilding, either in semi-detached arrangement set behind the house, or linking one house to the next.

By today's standards the houses are set in large plots of land intended to allow the occupants to engage in domestic vegetable production. This was achieved through siting in low-cost locations.

Construction

No-fines houses were built with a ten-inch (254mm) concrete shell cast in situ.^[1] The concrete for the entire outer structure was cast in one operation using reusable formwork. The ground floor was also concrete; the first floor was made with traditional timber joists and floorboards. Interior walls were a mixture of conventional brick and blockwork construction. To weatherproof the structure, the external facade was rendered.^[2]

Style

The regular, grey finish of the houses has led some to criticise the estates as having a bleak, concrete jungle aesthetic. This is accentuated by the layout of the pronounced geometric structure of many of the estates on which they were built. In more recent years (particularly since many were sold into private hands following the Housing Act 1980) no-fines estates have taken on a more varied look with most examples being painted (often in light pastel colours) and modified with porches or extensions.

Controversy

By the 1980s, political opinion had swung against social housing, and those living in it seemed to experience a relatively low quality of life and poor health. There were also concerns about the long-term structural soundness of the houses due to their novel construction. Parliament commissioned a report into the design of the houses and its impact on the occupants.^[3] It found that the health issues were due to poor windows and poor heating; the insulating properties of the no-fines walls were adjudged reasonable compared to single skin buildings of the same period. It concluded that the buildings were structurally sound. Subsequent improvements to windows and heating facilities have brought the houses broadly up to modern living standards and the design is now seen as largely vindicated. Some examples now enjoy additional exterior insulation, which can be readily identified from its distinctive design. The novel nature construction is still a residual concern and many lenders make restrictions on mortgages against no-fines houses. Wimpey no-fines houses are no longer in active construction.

Examples

No-fines houses were typically built in estates of a few hundred separate dwellings. Examples are found throughout the UK, and include

• Hesters Way and Rowanfield in Cheltenham
• Canley, Tile Hill and Keresley in Coventry
• Clifton Estate in Nottingham
• Innsworth and Elmbridge in Gloucester
• Abbeydale in Redditch
• Milton and Bishopbriggs in Glasgow
• New Addington in Croydon
• Edinburgh
• Leicester in Rowlatts Hill, Beaumont Leys, Braunstone Frith.
• The Millfields estate in Wednesbury, West Midlands
• Harestanes in Kirkintilloch
• Parsons Close in Portsmouth
• Orchard Park Estate in Kingston upon Hull
• Kirkby Liverpool
• Houndstone in Yeovil
• Hemlington in Middlesbrough
• Thorpe Edge Estate in Bradford, West Yorkshire
• Hilton in Inverness
• Barn Hall Estate in Wickford, Essex
