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.

CATHERINE HUGHES BUILDING PLANNING APPROVAL

MAY 2017

Catherine Hughes Building Planning Approval

Our new student accommodation scheme for Somerville College, has been awarded planning approval unanimously by Oxford City Council. The project, known as the Catherine Hughes Building, will provide 68 bedrooms, allowing the College to accommodate all their undergraduates on site. This is our third building for Somerville College, further to our work on the ROQ student housing and the extension to the Philip Dowson designed Wolfson building.

The new building has a frontage on to Walton Street, with a Graduate Reading Room at ground floor level. The use of red brick will reflect the neighbouring buildings, with articulated brickwork elements around generous windows to provide a rhythm to the façade. Framed setbacks at third floor level allow the new building to align with key levels on the adjacent Penrose Building and to provide variety to the roof line. Internally, bedrooms are arranged in to clusters with kitchens and circulation spaces utilising direct and borrowed natural light and forming focal points for social activity.

Enabling works, involving the demolition of existing buildings, are due to commence in the next few months, with the main construction expected to start on site at the beginning of 2018.
