The reception building is a transparent, glazed enclosure set between the brick walls of Brooklands House and the stable block; it forms a new main entrance, gives access to the stable block and house and acts as a communal space for receptions, exhibitions and social gatherings.The building's transparency distinguishes it from the adjoining historic buildings and allows views through to a walled garden.
The structure consists of four exposed steel portal frames of welded 254 x 146mm UB columns and beams connected at the eaves with 152 x 152mm UC edge-beams.As neither of the brick gable walls was plumb, the two outer frames are offset from them to accommodate their shape and to keep clear of existing foundations.The frames support a profiled metal deck, rigid insulation and an EPDM roof covering.
The east and west walls are glazed to clerestory level with 2 x 3m double-glazed units of clear toughened glass.
At ground level they slot into an aluminium channel which lies flush with the internal and external floor finish of York stone flag paving.At clerestory level they are supported by a 150 x 75mm parallel flange channel (PFC) bolted to the outside edge of the portal frame column.
The PFC also supports a row of doubleglazed fanlights running above the fixed glazing.The outer panes are extended to conceal box-section aluminium frames.
The fanlights are operated by remote control.
To articulate the wall/roof junction, the fascia is formed of a zinc-sprayed 200 x 90mm PFC bolted to the frame and thermally isolated from it. It is zinc-sprayed to match the zinc-clad eaves and upstand above it.A pressed aluminium drip throws water away from the glazing below.
