Overview
The Steane house is a distinctive post-war non-traditional property type, recognised for its use of precast reinforced concrete components and steel framing. These houses were developed to address housing shortages following the Second World War and remain a relatively uncommon form of construction today.
Steane houses were manufactured by J & A Steane between 1945 and 1950. Around 200 properties were constructed, typically as bungalows or two-storey detached and semi-detached houses, most commonly located in suburban settings.
Typical characteristics & construction
Steane houses are identifiable by their medium-pitch hipped roofs, usually finished with clay tiles, and by their distinctive external wall panels. These are formed from horizontally banded stone-faced precast reinforced concrete panels or brick slips.
A decorative flat concrete canopy is commonly found over the entrance, supported by projecting piers. Internally, layouts are generally straightforward, reflecting the practical post-war design approach.
| Element | Typical construction | Inspection focus |
|---|---|---|
| Substructure | Concrete raft foundation thickened at perimeter with DPC | Movement, cracking, damp-proof course continuity |
| Frame | Steel stanchions and perimeter ties set out on a steel jig | Corrosion, particularly at bases and connections |
| External walls | PRC panels and breeze concrete panels forming cavity walls | Cracking, joint movement, panel condition |
| Floors | Concrete ground floor; T&G boarding on composite joists above | Cracking, distortion, deflection |
| Roof | Timber and steel structure with bituminous felt and clay tiles | Felt deterioration, water ingress, tile condition |
Potential hazards & inspection priorities
The most significant concerns with Steane houses relate to corrosion of the steel frame and associated components. Superficial corrosion to steel stanchions is frequently evident, particularly at their bases.
Cracking to precast concrete and breeze concrete panels is also common, often associated with movement at panel joints. Voids within separating walls at first floor or eaves level can affect structural performance. Internally, distortion to floor and ceiling joists, cracking or lifting of ground floor screeds, and deterioration of roof felt coverings require careful assessment.
Is this house right for you?
Steane houses require purchasers to be comfortable with non-traditional construction and the need for targeted inspection of structural elements that are not always immediately visible.
- Commission a full building survey by a surveyor familiar with PRC housing
- Review evidence of past repairs to steelwork and concrete panels
- Allow for ongoing maintenance rather than assuming modern performance standards
Mortgage & resale considerations
The Steane house is not designated as defective under the Defective Premises Act. However, lending decisions are still influenced by condition, corrosion risk, and the quality of professional reporting.
Clear survey findings and evidence that known issues are managed or repaired are often central to mortgage and resale confidence.
What a survey can — and cannot — tell you
A building survey provides an informed assessment of the visible condition and construction of a Steane house. Inspections are non-intrusive and limited to areas that are accessible at the time of inspection.
- Identify visible cracking to precast concrete and breeze concrete panels
- Assess signs of corrosion to exposed steel components
- Comment on roof coverings, drainage details, and external envelope condition
- Review the general condition of accessible floors, ceilings, and structural elements
- 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 concealed steelwork within walls and floors
- Assess hidden structural elements behind finishes or linings
- Determine the full extent of corrosion where components are not exposed
- 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.
