Overview
The Reith House is a rare form of non-traditional housing dating from 1926. These semi-detached bungalows were manufactured by John Cran & Somerville Ltd and represent an early experiment in steel-based residential construction. Only four examples are understood to have been built, making this one of the least common steel house types encountered.
Reith Houses were constructed using flat and tray-like steel panels bolted together, with internal timber framing and fibreboard linings. Their limited numbers and unconventional detailing place them firmly within the category of specialist non-traditional housing.
Typical characteristics & construction
Reith Houses are semi-detached bungalows with a medium-pitch gable roof. Construction departs from traditional masonry, instead using bolted steel panels as the primary structural and external envelope system.
External walls are formed from flat, tray-like steel sheets fixed together through flanges. Timber framing is fixed between these flanges internally, with fibreboard linings providing internal finishes. A steel canopy over a recessed central entrance and a small window above are distinctive features.
Internally, partitions are timber stud with fibreboard linings. Floors are formed with tongue-and-groove boarding on timber joists at both ground and upper levels, and ceilings are similarly fibreboard lined.
| Element | Typical construction | Inspection focus |
|---|---|---|
| Substructure | Concrete strip footings with concrete under-building and dwarf walls | Settlement, cracking, and general stability |
| External walls | Bolted steel panels with internal timber framing and fibreboard lining | Corrosion, condition of coatings, moisture penetration |
| Roof | Tray-like steel panels forming a gable roof | Corrosion, fixings, junction detailing |
| Internal partitions | Timber stud with fibreboard linings | Damp damage, distortion, fire protection |
| Floors | Tongue-and-groove boarding on timber joists | Deflection, decay, ventilation |
Potential hazards & inspection priorities
The principal risk associated with Reith Houses is deterioration of the steel panels. Where protective paint or harling coatings have failed, corrosion can develop and may remain concealed behind internal linings.
Fibreboard linings, common for the period, also require careful consideration. These materials can present increased fire risk and may deteriorate if exposed to prolonged dampness. Inspection focus is therefore weighted towards external envelope condition and moisture management.
Is this house right for you?
Purchasing a Reith House requires an understanding of early steel-based construction and a willingness to manage ongoing maintenance. The limited number of properties means comparable evidence can be sparse, placing greater emphasis on individual condition.
- Commission a full building survey
- Assess the condition of steel panels and coatings
- Review any history of repairs or protective treatment
Mortgage & resale considerations
As with many non-traditional properties, mortgage acceptance and resale prospects are influenced by construction type, documented condition, and the clarity of professional reporting. Lender attitudes can vary and are often guided by survey findings.
Evidence of ongoing maintenance, corrosion control, and absence of significant unresolved defects is commonly influential.
What a survey can — and cannot — tell you
A building survey provides an informed assessment of the visible condition and construction of a Reith House. Inspections are non-intrusive and limited to areas that are accessible at the time of inspection.
- Identify visible corrosion to steel panels and associated coatings
- Assess signs of dampness, moisture ingress, and condensation risk
- 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 steel connections or hidden timber framing
- Assess structural elements behind fibreboard linings
- Determine the full extent of corrosion concealed within wall or roof panels
- 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.
