The RIBA's Stephen Lawrence Prize, sponsored by the Goldschmied Trust, went to Hatherley Studio, an innovative private house in Winchester designed by Richard Rose-Casemore.
The Stephen Lawrence Prize honours the best examples of projects with a construction budget of less than £200,000.
The judges said: 'Hatherley Studio is an exemplary work: taking a near impossible brownfield site in a domestic street;
creating a home for the architect and his partner, as well as a studio for her - an architectural photographic researcher; and persuading a reluctant planning authority through the sheer elegance of a Modernist solution which turned contextualism on its head. This is a tour de force that demonstrates, with great clarity, what can be achieved by an accomplished architect on a most unprepossessing site, in a sensitive context.
'To do it all on a budget of £100,000 is all the more remarkable, making it a worthy recipient of the Stephen Lawrence Prize.'
