The Unity Type II house is a post-war non-traditional property built during the 1950s using prefabricated reinforced concrete components.

The Unity Type I house is a post-war system-built property developed during the 1950s to address severe housing shortages following the Second World War. Manufactured by Unity Structures Ltd and Unity House Construction, approximately 19,000 Unity Type I and Type II houses were built across the UK. These properties typically use precast reinforced concrete columns and panels, with medium-pitched tiled roofs, and are now recognised as defective under the Defective Premises Act due to inherent structural risks associated with their construction.
