Overview
The Craig Atholl house is a rare non-traditional property type manufactured by Atholl Steel Houses Ltd and designed by Sam Bunton & Associates. Constructed in 1951, only four two-storey semi-detached examples were built, making surviving properties uncommon within the UK housing stock.
Craig Atholl houses are steel-framed, semi-detached dwellings dating from the early post-war period, characterised by rendered elevations, distinctive eaves detailing, and mixed concrete and timber floor construction.
Typical characteristics & construction
Craig Atholl houses are two-storey semi-detached dwellings with medium-pitch gable roofs covered in concrete tiles. External walls are rendered with a roughcast finish, and a pronounced bellmouth detail is formed at eaves level on the gable walls.
Door and window openings feature PS surrounds, with a flat canopy above the front entrance supported by tubular steel columns. Internally, construction is a hybrid of steel framing, concrete, timber, and plasterboard elements typical of early 1950s experimental housing.
| Element | Construction | Inspection focus |
|---|---|---|
| Substructure | Concrete strip footings | Settlement, cracking, general stability |
| Frame | RSJ and RSA steel stanchions with steel beams and trusses | Corrosion, access limitations, protective coating condition |
| External walls | Rendered walls with Bellrock plaster panels and concrete infill | Cracking, dampness, render failure |
| Separating wall | Brick cavity wall | Cracking, soundness, fire separation |
| Ground floor | Concrete | Dampness, levelness, cracking |
| First floor | Timber | Deflection, vibration, local decay |
| Roof | Timber sarking with concrete tiles | Tile condition, leaks, timber deterioration |
Potential hazards & inspection priorities
The principal concern with Craig Atholl houses is corrosion of the concealed steel frame. Moisture ingress, whether through cracked render or condensation, can accelerate deterioration and compromise structural performance.
Insulation levels are limited by modern standards, increasing condensation risk. As with many properties of this period, asbestos-containing materials cannot be ruled out without appropriate testing. Damp and mould may also arise where ventilation or maintenance has been poor.
Is this house right for you?
Purchasing a Craig Atholl house requires an understanding of non-traditional steel-framed construction and acceptance that inspection access to key elements is restricted.
- Commission a detailed building survey
- Review past maintenance and repair records
- Budget for ongoing monitoring and remedial works
Mortgage & resale considerations
Mortgage availability for non-traditional properties is influenced by construction type, condition, and the clarity of professional reporting. Lender criteria can vary and may change over time.
Clear evidence of maintenance, absence of unresolved structural concerns, and comprehensive survey documentation 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 Craig Atholl house. Inspections are non-intrusive and limited to areas that are accessible at the time of inspection.
- Identify visible cracking to rendered walls and finishes
- 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 requiring 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
- Assess hidden structural elements behind linings or finishes
- Determine the effectiveness of unknown protective coatings
- Inspect areas that are inaccessible at the time of inspection
Where higher-risk indicators are identified, further specialist or intrusive investigation may be recommended.
