Overview
The Coventry Corporation house, also referred to as the Radiation House, is a rare example of immediate post-war British housing. Designed by Donald E. Gibson and Edric Neel and constructed in 1945, only two of these properties were built. The design formed part of the wider response to acute housing shortages following wartime destruction, with an emphasis on speed of construction and material efficiency.
Typical characteristics & construction
Coventry Corporation houses are two-storey, semi-detached properties. The roof is a shallow pitch gable covered with profiled asbestos cement tiles. External wall construction combines precast concrete panels with asbestos cement sheeting, while internal walls are timber framed and infilled with wood wool.
The structural frame is formed from tubular steel stanchions, lattice beams, and roof trusses, all originally protected with red oxide paint. Floors are formed using suspended precast reinforced concrete panels at ground level and plywood on timber battens at first floor level.
| Element | Construction | Inspection focus |
|---|---|---|
| Substructure | Concrete strip footings with PC underbuilding | Cracking, spalling, moisture-related deterioration |
| Structural frame | Tubular steel stanchions and lattice beams | Corrosion, particularly at stanchion bases |
| External walls | Precast concrete panels and asbestos cement sheets | Panel joint pointing, water ingress |
| Floors | Suspended PRC ground floor, plywood first floor | Deflection, moisture effects |
| Roof | Profiled asbestos cement tiles | Mould growth, weathering |
Potential hazards & inspection priorities
The most significant risk associated with this house type is corrosion to the tubular steel stanchions, particularly at their bases. This was evident during inspection guidance for these properties and is a well-recognised issue where moisture is present.
Secondary concerns include deterioration of the steel setting out sill, breakdown of pointing between precast concrete panels, and mould growth to the underside of asbestos cement roof coverings. Cracking and spalling to precast concrete underbuilding are also commonly recorded.
Is this house right for you?
A Coventry Corporation house requires a clear understanding of non-traditional post-war construction and a willingness to manage ongoing maintenance. Particular emphasis should be placed on the condition of the steel frame and the effectiveness of protective coatings.
These properties benefit from careful, informed inspection rather than assumptions based on age alone.
Mortgage & resale considerations
Mortgage acceptance for non-traditional housing is influenced by construction type and condition. Clear professional reporting and evidence of maintained structural elements are central considerations when assessing lending and future resale prospects.
What a survey can — and cannot — tell you
A building survey provides an informed assessment of the visible condition and construction of a Coventry Corporation house. Inspections are non-intrusive and limited to areas that are accessible at the time of inspection.
- Identify visible corrosion to accessible parts of the tubular steel frame, particularly at stanchion bases
- Assess breakdown of pointing between precast concrete panels and signs of water ingress
- Comment on mould growth or weathering to the profiled asbestos cement roof coverings
- Note cracking or spalling to the precast concrete underbuilding and the condition of accessible floors
- Highlight defects that may require repair, monitoring, or further investigation
However, there are limitations to what a survey can determine without intrusive investigation.
- Confirm the condition of steel stanchions, lattice beams, and roof trusses concealed behind panels and linings
- Determine the effectiveness of the original red oxide protective coating to concealed steelwork
- Assess the condition of the steel setting out sill where it is hidden from view
- Inspect areas that are inaccessible or covered at the time of inspection
Where higher-risk indicators are identified, further specialist or intrusive investigation may be recommended.
