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.

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 SITE FOR SAURIIS

JANUARY 2017

Our proposal to redevelop the grounds of the Natural History Museum is due to start on site this month. The work to the main entrance – the first of three phases – will introduce level access to this area for the first time while also restoring the Grade-I listed fabric to its former glory.

The works include changing levels, repaving the forecourt, restoring railings, installing planting, and repairing or reinstating original terracotta details across the site.

Ahead of this, the main entrance and central hall of the Museum are now closed while both teams gear up for construction – including some unusual enabling works. As part of these works Dippy the diplodocus has now been dismantled ahead of going on tour around the country; to be eventually recast in bronze for the next phase of our project.

The railings have now been removed for off-site restoration and re-painting:

And scaffolding is also going up for the removal of display cases and various specimens:

This will need to go up again halfway through construction of Phase 1 allow for delivery of the blue whale skull through our active site. Here it is just before it left the Museum.

If you’re wondering how that that will fit through the front doors, the answer’s simple: the same way the elephants do.

Phase 1 is due to complete mid-July ahead of the main entrance reopening to the public shortly after. In the meantime, there’s a pop-up conservation studio in the Darwin Centre – which we highly recommend – where you can see the conservationists at work restoring the whale’s bones.
