A former wartime defensive structure in Oxfordshire has been listed for sale at £650,000.

The property in Bicester was previously part of a nearby RAF establishment and now comprises two bedrooms, two bathrooms and a raised terrace area.

The conversion has preserved the building’s characteristic red brick exterior while maintaining its position partly concealed beneath two large earthwork barriers designed to shield against blasts.

According to developer City & Country, the original shelter boasted four-foot-thick walls and contained no windows.

The complex originally housed decontamination rooms, sealed entry systems and a communications hub during its active service as a military installation.

Natural light now floods the home through roof light panels and sliding glass doors that lead to a private terrace.

Estate agent Fine & Country is promoting the unusual residence at £650,000, characterising it as paying homage to its armed forces heritage.
