BALLIOL COLLEGE, SPORTS PAVILION
NOVEMBER 2019
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.

A DAY OUT OF THE OFFICE
MAY 2014
We breathlessly boarded the 08.55 to Darlington. Like skilled waitresses we had kept our homemade, oversized, A1 box perfectly level throughout our chase through Kings Cross Station. The immaculate foam-board creation fitted perfectly on top of a double-seat on the near-empty train. East-Coast mainline rules are clear however; the guard reminded us that seats are for people only and at Peterborough we were duly ordered to deliver our carefully crafted friend to the dedicated luggage wagon at the front of the train.
The box was purposefully constructed to house a 1:150 context model of Bishop Auckland Town Square with ‘slot-inable’ building options for the site in question. The model was made for a meeting with Durham County Council and English Heritage at Auckland Castle that same afternoon.
Despite our ticket inspector’s fussiness, we were carried to our destination with the box and its contents in good order.
After a communal lunch with the review panel, the dozen-odd experts collected themselves around a table where the model had been assembled. The object took up so much space that notebooks occasionally and apologetically slid from the edges of the table.
For the following three hours, a multitude of building blocks representing different proposals for the new Welcome Building were inserted into the corner site. The new building is to link town and castle, engaging the new with the old, with our site at the axis of this pirouetting dance.
As we waltzed around the model, interchanging different pieces into our self-made jigsaw, a negotiation occurred between the many different people around the room, a parallel perhaps to the building itself.
During the second part of the afternoon, the presentation became more conceptual. The tower – the key feature of the proposal – was discussed in its meaning, shape and materiality. Was it a campanile, a siege tower, a lighthouse or a scaffold? Each version was debated with varying levels of approval or skepticism. We answered questions by pulling off bits of white card or finding any handy props to add on to the model; notepads, milk jugs and i-phones were used.
We left the meeting feeling excited, there was only this box to get all the way back to the office.
