The Post-War Building Boom
The period from 1945 to approximately 1980 produced some of the most diverse housing in Britain. The urgent need to rehouse a population devastated by wartime bombing led to rapid experimentation with new construction methods, many of which are now considered "non-standard construction" by lenders and insurers.
Understanding the construction type of a post-war property is critical before proceeding with a purchase, as it directly affects mortgageability, insurability, and long-term maintenance costs.
Standard vs Non-Standard Construction
Most properties built to traditional brick-and-block methods in this period present no unusual challenges. However, a large number were built using system-built, prefabricated, or concrete-frame methods.
| Construction Type | Examples | Potential Issues |
|---|---|---|
| Traditional brick-and-block | Most private semis | Generally mortgageable |
| Steel frame (BISF) | BISF houses, Airey | Lender restrictions; specialist surveys needed |
| Concrete panel (in-situ) | Wimpey No-Fines, Laing | Carbonation, reinforcement corrosion |
| Precast reinforced concrete (PRC) | Airey, Orlit, Reema | Designated defective under Housing Defects Act |
| Prefabricated temporary (BISF, aluminium) | Post-war prefabs | Rare; often non-mortgageable unless rebuilt |
| Timber frame | Scandinavian-influenced | Generally fine if well-maintained |
PRC Homes, Designated Defective Properties
Certain precast reinforced concrete (PRC) house types were formally designated as defective by the Housing Defects Act 1984 following concerns about structural deterioration. These include Airey, Reema, Unity, and Cornish Unit types, among others. Mortgage lenders will typically not lend on unrepaired designated defective PRC homes. Some have been repaired under approved schemes (PRC Homes Ltd licenced repairs), after which they may again be mortgageable.
What to Check Before Buying
Confirm the Construction Method
If you suspect a property may be system-built, ask the estate agent and instruct your surveyor to confirm the construction type. Title documents may refer to the original build method. HM Land Registry records sometimes include references to the building type for council-built stock.
Instruct a RICS Level 3 (Full Building) Survey
For any post-war property with a potentially non-standard construction, a RICS Level 3 survey is essential. The surveyor should identify the construction type, assess any structural defects, and comment on mortgageability.
Check the EPC
Post-war properties frequently have poor energy performance, typically D, E, or F band, due to thin cavity walls, poor loft insulation, and original single glazing. View the current EPC on Property Passport UK to understand the baseline and what improvements would be most effective.
Council Tax and Tenure
Former council houses sold under the Right to Buy from the 1980s onward are typically freehold houses or long-leasehold flats. Check the current title and tenure carefully, some local authorities retained covenants affecting sale price on resale within a specified period.
Why Post-War Properties Can Be Good Value
Despite the cautions above, most post-war brick-built properties represent excellent value, larger plot sizes, garages, and off-street parking are common compared to Victorian terraces. With the right survey and appropriate mortgage advice, post-war homes remain a solid choice for buyers who understand what they are buying.
