Overview
The Spaceway House is a highly unusual form of non-traditional housing developed during the mid-1970s. Designed and manufactured by Spaceway Ltd in collaboration with Medway Building Group Ltd, these properties were constructed in 1976, with only around 40 units ever built. They are typically found as detached or linked bungalows in small clusters across the UK.
Spaceway Houses were constructed using an experimental steel-framed volumetric system with glass-reinforced plastic external cladding. Their limited numbers and distinctive appearance make them relatively rare within the UK housing stock.
Typical characteristics & construction
Spaceway Houses are single-storey dwellings, usually arranged as detached or linked bungalows. Roofs are shallow pitch gable or flat in form and finished with bituminous felt coverings. A flat roof canopy is commonly provided over the front entrance.
The primary structure is a volumetric steel box frame, formed using hollow box steel stanchions at the corners with C-section steel beams and floor joists. External walls are timber-framed panels clad externally with flat glass-reinforced plastic sheets and internally lined with plasterboard. Foam insulation is installed between the timber studs.
| Element | Typical construction | Inspection focus |
|---|---|---|
| Substructure | Concrete pads at corners | Settlement, alignment, bearing condition |
| Primary frame | Steel box stanchions and C-section beams | Corrosion, protective coating condition |
| External walls | Timber frame with GRP cladding | Panel degradation, fixings, moisture ingress |
| Roof | Shallow pitch or flat roof with felt covering | Felt wear, water ingress, detailing |
| Windows | Side-sliding units with rounded corners | Operation, seals, water tightness |
Potential hazards & inspection priorities
The principal inspection concerns relate to the long-term performance of the steel frame and the glass-reinforced plastic cladding. Corrosion of steel elements can compromise structural integrity if protective coatings have failed. GRP panels may suffer from surface degradation, cracking, or failed joints, increasing the risk of water ingress.
Roof coverings are another priority, as aging bituminous felt is prone to splitting and blistering. Failure of the roof membrane can lead to concealed moisture penetration affecting both the timber wall panels and steel frame.
Is this house right for you?
A Spaceway House may appeal to purchasers who are comfortable with non-traditional construction and understand the importance of condition-led assessment rather than age or appearance alone.
- Commission a full building survey
- Review past repairs to cladding, roof coverings, and steelwork
- Allow for ongoing specialist maintenance
Mortgage & resale considerations
Mortgage availability for Spaceway Houses depends on lender appetite, clarity of construction details, and the condition reported at survey. Non-traditional materials and limited comparable stock can influence lending decisions.
Clear professional reporting and evidence of maintained structural elements are commonly influential when considering resale prospects.
What a survey can — and cannot — tell you
A building survey provides an informed assessment of the visible condition and construction of a Spaceway House. Inspections are non-intrusive and limited to areas that are accessible at the time of inspection.
- Assess visible condition of GRP cladding and joint details
- Identify signs of corrosion to accessible steel frame elements
- Review roof coverings, drainage, and weatherproofing details
- Comment on internal linings, floors, and ceilings
- 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
- Inspect hidden wall panel fixings or insulation
- Assess covered or inaccessible areas
Where higher-risk indicators are identified, further specialist or intrusive investigation may be recommended.
