View of the front elevation of Sipson House, partially obscured by trees, at 595 Sipson Road, Sipson, looking north. Sen in vacant possession with the upper- and lower-ground floor windows boarded-up on the inside. The late eighteenth-century house is Grade II listed, listing entry 1284985, with a later nineteenth-century extension to the left-hand side. Seen with a clear corrugated sheeted shelter in front of the basement doorway, beneath the main entrance stairs. The house has a gravel drive edged with untended flower beds, an overgrown path, and half-barrel planters. The garden door, seen with a ladder laid in front, right, leads into a corrugated iron shed. The house is fed by telephone wires and has a UHF aerial on the chimney stack. The large former family home fell into a state of disrepair whilst used as offices by the Civil Aviation Authority. It was partially demolished and rebuilt behind the existing facade c1980, thereafter named 'Sipson Court' and continuing in office use. It changed to a residential children's home and nursery school c2009. The building is currently just outside the eastern border of the Heathrow expansion 'red zone' and therefore potentially affected should Heathrow proceed with plans to build a third runway.
