BALLIOL COLLEGE, SPORTS PAVILION

NOVEMBER 2019

Balliol College, Sports Pavilion

7:45 AM, London Bridge. The train from Uckfield just entered the station and is spitting out hundreds of commuters, flowing past us. We hop on the now empty train and leave London to visit our timber sub-contractor’s workshop in East Sussex.

We are fast approaching the construction stage of our Sports Pavilion project for Balliol College in Oxford and were invited to review a mock-up of the roof structure. The pavilion roof is formed of slender sweet chestnut glulam joists; 10 layers are stacked on top of each other, each layer cantilevering further into the space, creating a coffer.

From outside the roof structure expresses itself as a lantern, popping up in the centre of the building. The lantern is fully glazed, allowing for rays of sunshine to enter through the stacked glulam. In the evening, the dense timber lattice will be highlighted by a subtle glow, originating from LED strips, that are recessed in the top of the glulam joists.

Lighting strategy detail plan and section

The mock-up was used to test the connection details between the individual layers of glulam, the construction sequence, and the integration of the LED strips and the associated wiring. Preceding the assembly of this mock-up, these details have been worked through and coordinated in many lengthy design workshops, involving the contractor, structural and electrical engineers, the timber sub-contractor, electricians and us architects. As such, it was even more enjoyable to review the mock-up with all the parties involved and to see our combined efforts bearing fruit.
