Jerwood Vanbrugh Theatre, RADA
The auditorium, arranged on three levels, including dress and upper circles, around an 8 metre cube, is designed for teaching drama. It can be adapted to form a variety of stage configurations, from 'in the round' to angled proscenium arch. In the latter configuration, the stalls are protected by a balustrade and reached by a pair of steps. For 'in the round'configurations, the seating rostra, balustrade and steps are designed to be removable and the floor, which can be adjusted in height, is raised to its highest position.
The balustrade to the stalls consists of paired steel balusters surmounted by a wide crown-cut maple handrail with inset lights on the underside.A series of black polypropylene coated wires fitted with tensioners are stretched between the balusters, designed to be as light and transparent as possible.The legs of the balusters fit into slots set in stainless steel cover plates in the hardwood floor; they are locked in position against a steel bracket assembly by turning Allen keys.Lighting cables run down between the paired balusters and are powered via 'hot-shoe' connectors concealed below the cover plates.
The balustrade to the steps is formed of stainless steel tubes which slot into spigots in the lowest tread.
The dress circle is constructed of cast in situ concrete, tapering to 150mm thickness at the curved edge.
A 150 x 150mm RSA runs along the edge to support the balusters and acts as a conduit for theatre production services - such as light and sound; they are concealed behind a removable bullnosed aluminium cover plate.
The balustrade is canted to reflect the natural seated position and supports a removable lighting bar.
