Overview
The Thames House is a distinctive form of non-traditional housing developed during the 1940s in response to post-war housing demand. Designed by Joseph Emberton and manufactured by Briggs Motor Bodies Ltd, these properties reflect the industrialised construction methods adopted during this period.
Thames Houses are primarily found in various parts of the UK and are recognised for their unusual steel-based construction and curved roof form, making them visually and technically distinct from traditional masonry housing.
Typical characteristics & construction
Thames Houses are generally two-storey, semi-detached properties constructed using a steel frame system. The design prioritised speed of construction and efficient use of materials during the post-war period.
External walls are formed from steel sheets with aerated concrete infill and internal plaster finishes. The roof structure comprises curved steel panels finished externally with bituminous felt.
| Element | Typical construction | Inspection focus |
|---|---|---|
| Substructure | Concrete strip footings with concrete under-building and DPC | Settlement, moisture ingress, DPC effectiveness |
| Frame | PSC frame panels with PS ring beams | Corrosion, movement, protective coating condition |
| External walls | Steel sheets with aerated concrete and plaster | Corrosion, damp penetration, surface deterioration |
| Roof | Curved steel panels with bituminous felt | Felt condition, leaks, corrosion at joints |
| Floors | Timber boarding on steel joists | Deflection, decay, corrosion to steel supports |
Potential hazards & inspection priorities
The primary concern with Thames Houses is corrosion of the steel frame and panels, particularly where original protective coatings have failed. Moisture ingress can accelerate deterioration and lead to structural weakness.
Thermal performance is another notable issue. Steel construction can result in heat loss and condensation risk if insulation levels are inadequate or poorly detailed.
Is this house right for you?
Purchasers considering a Thames House should be comfortable with non-traditional construction and prepared for ongoing maintenance responsibilities.
- Commission a full building survey
- Assess corrosion protection and past repairs
- Consider insulation upgrades carefully
Mortgage & resale considerations
Lender acceptance for non-traditional housing can vary. Decisions are often influenced by construction type, condition, and the clarity of professional reporting.
Evidence of maintenance, effective corrosion control, and clear survey findings are commonly influential factors.
What a survey can — and cannot — tell you
A building survey provides an informed assessment of the visible condition and construction of a Thames House. Inspections are non-intrusive and limited to areas that are accessible at the time of inspection.
- Identify visible corrosion to steel frames and panels
- 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 elements
- Assess hidden corrosion behind finishes or linings
- Determine the full extent of internal panel deterioration
- 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.
