Overview
The Telford house is a distinctive early 20th-century non-traditional property type constructed in 1924 by Braithwaite & Co. Ltd. With approximately 300 units built, these houses form a small and identifiable group within the UK housing stock and are also known as the Braithwaite or Braithwaite Unit Frame.
They are generally found in areas associated with early industrial development and represent an experimental approach to mass housing using steel-based construction.
Telford houses are two-storey semi-detached properties constructed using storey-height steel wall panels with timber framing and asbestos cement linings. Their limited numbers and specialist construction mean they require informed inspection.
Typical characteristics & construction
Telford houses are two-storey semi-detached dwellings with medium-pitch hipped roofs. Roof coverings are commonly steel panels or plain clay tiles, with some later variants re-roofed using interlocking concrete tiles.
External walls are formed from storey-height flat steel panels with rounded corners and a projecting band course at first-floor level. A single-storey bay window is a common architectural feature.
Internally, timber framing is tied back to the steel panels using metal straps and lined with asbestos cement sheets. Floors are a combination of concrete ground floors and timber upper floors with tongued and grooved boarding.
| Element | Typical construction | Inspection focus |
|---|---|---|
| Substructure | Concrete trench fill with ground floor slab | Cracking, kerb condition, signs of movement |
| External walls | Storey-height steel panels with timber framing | Corrosion, panel bowing, fixing deterioration |
| Separating wall | Double cavity timber stud with central steel panels | Stability, moisture effects, lining condition |
| Floors | Concrete ground floor, timber first floor | Rot, distortion, localised dampness |
| Roof | Steel panels or clay tiles on steel and timber structure | Corrosion, covering condition, water ingress |
Potential hazards & inspection priorities
The most significant concern with Telford houses is corrosion of the steel wall panels, particularly at the bases. This was evident during inspection of comparable properties and often extends to fixing bolts and panel joints.
Additional issues include bowing of wall panels, cracked or broken concrete kerbs and aprons, rot within timber framing, and superficial corrosion to steelwork within the roof space.
Is this house right for you?
A Telford house is best suited to purchasers who understand non-traditional steel construction and are prepared to assess condition on its individual merits rather than age alone.
- Commission a full building survey
- Pay particular attention to steel panel condition
- Factor in specialist repair requirements
Mortgage & resale considerations
Mortgage and resale acceptance for Telford houses can vary depending on condition, repair history, and the clarity of professional reporting. Steel corrosion and asbestos-containing materials are commonly scrutinised.
Clear evidence of maintenance and informed survey advice are often influential in lender decision-making.
What a survey can — and cannot — tell you
A building survey provides an informed assessment of the visible condition and construction of a Telford house. Inspections are non-intrusive and limited to areas that are accessible at the time of inspection.
- Identify visible corrosion to steel wall panels and fixings
- 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 steelwork behind linings
- Assess hidden timber framing and fixings
- Determine the full extent of corrosion within panel joints
- 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.
