Landfall is a house in Poole, Dorset, England, that was built between 1936 and 1938 by the architect Oliver Hill in the modernist style. It has been designated as a Grade II* listed building by Historic England.The house was designed and built for Edna and Dudley Shaw Ashton. A film was made of the construction of the building which won a national amateur film award. Dudley Shaw Ashton became a film director. The circular room in the centre of the house doubled up as a film cinema and was inspired by the 1934 British musical film, Evergreen. It had a circular rug by Marion Dorn in off white with a central motif. The fitted furniture was designed by Betty Joel. Flying circular stairs, constructed of reinforced concrete, led from the balcony to the garden terrace. Beneath the terrace is an air raid shelter. Ship's stairs led from the first floor up to the sun room on the roof.
