Local Knowledge
The Greenford Housing Stock
Most residential streets in Greenford sit in two building periods: the 1920s and 1930s interwar expansion that produced the cavity-wall semidetached and terraced houses on streets such as Ridding Lane, Ferrymead Avenue, Hotspur Road, and Mandeville Road; and post-war terrace and estate development from the 1950s through 1970s across Ravenor Park and the Horsendon Hill corridor.
These 1930s semis are ideally suited to the two most value-adding renovation projects available in UB6: a single-storey rear extension opening up the kitchen into the garden, and a Velux or dormer loft conversion converting the redundant roof space into a bedroom with ensuite. Properties in the Victoria Cottage Estate, the Ravenor Farm Estate, and the streets closest to Greenford station also benefit from integral garage conversions, which in Greenford commonly become home offices given the area's commuter demographic.
Older Victorian properties in the streets closest to Greenford Broadway are solid-wall pre-1919 construction requiring lime-compatible plastering and breathable render rather than the gypsum and sand-and-cement systems appropriate for the 1930s cavity-wall stock.
