These three drawings are related to five drawings in the collection of the Victoria & Albert Museum (see P. du Prey, op.cit. above). Of those drawings two are side elevations (north and south). Another is a ground floor plan with the same form as SM drawing 1 but with a breakfast room added and the kitchen quarters differently arranged. The other is a variant front elevation with a solid parapet, decorated with festoons, which conceals the roof. There is also at the V&A a detail of the Doric portico dated 22 August 1793 (V&A 3307.63-66, 3307.73). It seems that the Soane Museum drawings and those from the Victoria & Albert Museum are among the 'fair drawings' sent to Mrs Yorke and brought back to the office by Soane (see General Notes above).
Soane's design is for a symmetrical, compact villa with inscribed dimensions of 48 feet 6 inches (which is incorrect and should be about 60 feet) wide by 50 feet deep and with a semicircular (baseless) Doric portico and a three-window, single storey bow (with balcony above) to the circular drawing room on the opposite side. The three-bay villa has two floors above a raised basement and is plain except for the porch, cornice (with T-shaped toothing) and the two ground floor windows set back in a semicircular recess.
The idea of a villa with a circular reception room facing the garden is found earlier in Soane's student designs for a 'large villa' 1779 and a 'hunting casino' c. 1780 (see under Soane's architectural education ... 1778-80).
