Numbers 50 and 50a Winchester Street are a pair of maisonettes converted from a mid-Victorian house by the architects Roy Stout and Patrick Litchfield, for their own use.

What attracted them to the building was the fact that it was a corner house with a side entrance, giving it a front room on the ground floor that did not have the usual entrance passage cut out of it. It also had an area at the basement level, which continued around the corner on Clarendon Street and which gave access to no less than eight vaulted cellars.

Stout and Litchfield lived in the building with their families, and they also ran their architecture practice from a home office at the front. The project was featured in the Architectural Review shortly after its completion in 1970.
