A conservatory with a frameless glass roof
The house is a series of pavilions set on three sides of a landscaped courtyard open to the south-west. A singlestorey lean-to conservatory runs along the south-west facade. At ground floor level, the wall behind it, together with the adjacent external walls to kitchen and living room, are designed as 'garden walls'and contain deep 'pockets' lined with precast concrete shelves to hold young plants.
The conservatory is used for plant storage in winter and as an extra dining/sitting space in summer. It has a roof of frameless 15mm toughened glass panels and a frameless glazed gable on the north-west side where it abuts a portion of singlestorey flat roof and concealed gutter. The roof panes are supported between the gables on a pair of laminated glass beams. Their top edges rest on a nylon spacer and are silicone-fixed into an aluminium channel which has been recessed deep into the wall to avoid intrusive flashings; it is sealed with silicone at the edges.
The roof is pinned back to the wall with a timber connector bolted to steel shoes fixed to the joists. At eaves and gable, the edges of the glass panes are sealed with silicone; an additional silicone bead runs just inside the edge to act as a drip.
The conservatory wall is framed in treated softwood timber, with a row of frameless glass fanlights at the eaves and double-glazed units below. A pair of timber-framed glazed sliding doors mounted on rubber wheels run along a fabricated steel channel set just below the eaves.
The conservatory opens onto a bridge of timber slats, supported by steel T-shaped sections, over a decorative concrete water trough.
