This room is very nearly not a room, to be inside yet feel outside. Glass technology is pushed to a new level, with simple walls acting as cantilever to support the roof. Columns or fins are done away with, leaving the wall plane absolutely clear. The roof is a single sheet of glass, supported by the thinnest of glass beams. Glass walls slide into a solid slate base, leaving just a fine slot for rainwater and fibre optic lighting. Gaps in the floor slates allow for air to be pumped in and high level vents in the brick wall pull air out, keeping the space at external temperatures during summer. Underfloor heating warms the space during the coller months and two simple glass doors slide from within the wall thickness to separate the space from the rest of the flat. At night the garden and pool are lit in varying colours, the glass walls breaking into a multitude of reflections.
