Overview
The War Office No-Fines house is a rare and historically significant form of post-war housing developed in 1953. These properties were produced as part of a collaboration between the Building Research Station and the War Office, responding to the urgent need for durable and quickly constructed homes following extensive wartime damage.
War Office No-Fines houses were constructed in limited numbers, with only 20 units built. They are typically two-storey semi-detached houses formed in no-fines concrete and finished with external render.
Typical characteristics & construction
War Office No-Fines houses are generally two-storey semi-detached properties. External walls are formed in 11-inch no-fines concrete, a material containing no fine aggregate, and finished externally with render.
Roofs are medium pitch gable constructions covered with concrete tiles and supported on timber rafters. Internally, walls are lined with coffered plaster panels, often incorporating bitumen coatings and wire ties associated with the original shuttering system.
| Element | Typical construction | Inspection focus |
|---|---|---|
| Substructure | Concrete foundations (details limited) | Settlement, cracking, general stability |
| External walls | 11-inch no-fines concrete with render | Cracking, render condition, moisture penetration |
| Separating wall | No-fines concrete with plaster panel lining | Cracking, soundness, movement |
| Floors | Concrete ground floor; RC slab with precast joists at first floor | Deflection, cracking, vibration |
| Roof | Timber rafters with concrete tiles | Tile condition, leaks, timber deterioration |
Potential hazards & inspection priorities
Dampness is one of the more commonly reported issues, particularly within kitchens and other areas with higher moisture generation. This is often linked to ventilation limitations and the moisture behaviour of no-fines concrete.
Cracked or loose internal plaster panels are also frequently encountered. These can arise from building movement or long-term stress within the panel fixing system and should be assessed for extent and risk of detachment.
Is this house right for you?
Purchasers should be aware that War Office No-Fines houses differ from conventional masonry construction and require assessment based on their specific condition rather than age alone.
- Commission a full building survey
- Pay particular attention to dampness and internal finishes
- Review evidence of past repairs and maintenance
Mortgage & resale considerations
These properties are not classified as defective under the Defective Premises Act. However, lender attitudes can vary depending on condition, documentation, and the clarity of professional reporting.
Evidence of good maintenance and clear survey findings will usually be influential factors in lending and resale decisions.
What a survey can — and cannot — tell you
A building survey provides an informed assessment of the visible condition and construction of a Wimpey No-Fines house. Inspections are non-intrusive and limited to areas that are accessible at the time of inspection.
- Identify visible cracking to no-fines concrete walls and associated render
- 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 reinforcement within no-fines concrete
- Assess hidden structural elements behind finishes or linings
- Determine the full extent of carbonation or internal concrete 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.
