View of the south-east corner of Sipson House, at 595 Sipson Road, Sipson, looking south. The late eighteenth-century house is Grade II listed, listing entry 1284985, with a later nineteenth-century extension to the right-hand side, seen with a substantial corrugated iron shed to the left. The house has a sizeable rear car park, seen filled with Ford, British Leyland, and Vauxhall models. Farm outbuildings can be seen to the right, with the stairwell at the end of the, now named, Radisson Hotel seen under construction, just visible beyond. 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.
