The Tree House is a 5 bedroom house clad in black glass, designed by Ian McChesney and completed this year. It's been written about this week in The Architect's Journal (£) and Dezeen.
It's in a leafy South-east London conservation area, and when I took some photos of it earlier this week, it was doing a beautiful job of reflecting the clear blue sky and autumn leaves surrounding it.
If you really really like it, you can snap it up for for £1.75million at The Modern House Ltd.
