Xylotek delivered this theatre stair, plus a stairway to the floor below, as part of Arup’s new offices in the 80 Charlotte Street building by Make Architects. Arup Architecture designed the stairs to form a social centrepiece within two floors of flexible-working space.
The main structure is made of Douglas fir cross-laminated timber, chosen for its visual appearance and because it is harder wearing than the more conventional spruce CLT. Surround acoustic screens are made of oak, and Xylotek detailed bespoke handrails and other componentry.
Piveteau-Bois supplied the CLT and glulam components to dimension. Then they worked in our Bristol workshop to produce the detailed geometries, carry out pre-assembly and add surface treatments.
Fire testing was carried out to ensure a non-slip finish and the required fire resistance was achieved.
Given the tight access to the site, the installation needed careful coordination and was carried out with hand-operated lifting equipment.
The theatre stairs provide a space for informal gatherings, meetings and lectures and provide central circulation between the office floors.
