A Hither Green house designed by the homeowners has won an architecture award.
The "beautifully composed" house won a Royal Institute of British Architect's Regional Award and Regional Small Project of the Year.
The private home won alongside developments such as the Tate Modern Switch House and Box Park Croydon.
The jury said: "This beautifully composed, new-build house is located on a small street in Hither Green.
"The opposite side of the street is defined by a typical row of Victorian terraced houses but the side on which the house sits, forms the back wall of gardens with occasional garages and out-buildings.
"The new house makes a significant and appropriate urban contribution by providing a clear edge and identity to this side of the street, which was previously lacking in definition.
"Within the house, magical proportions and an ingenious use of space provides a set of zen-like domestic interiors and courtyard spaces, fitting for a small family.
"As an infill project, the house and courtyards are largely inward-looking, providing privacy and tranquillity from the street. The interior and exterior spaces merge together seamlessly, extending the space of the living-rooms out into the gardens.
"Details have been meticulously considered down to the electrical switches and the setting-out and execution is near-perfect. The house is a self-build project for the owner/architect and as such was delivered at a very low build cost.
"The judges felt that this house was out-standing."
South West London Jury chair Matthew Lloyd said: “The RIBA Awards for 2017 for the London Region have been given for outstanding building design across a very diverse range of building types and scale.
"This includes a new emergence of significant public sector housing projects, several galleries big and small, national headquarters buildings, significant NHS hospital projects, schools notably in the private sector this time, beautiful office buildings, transport interchanges, and finally the extraordinary small house projects that are so characteristic of this dense city.
"The year has demonstrated once again the breadth of the capital’s architectural output at the very high level that the RIBA programme requires, and the juries took enormous pleasure in selecting a most exemplary set of schemes.”
