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.

‘What do you see when you look up through the trees? Try to imagine this moment in a pretended place or part of a journey through a particular sequence of spaces. How does one describe this experience? What is it about spaces in nature, for example forests, which make them fascinating yet at the same time unsettling places to inhabit? A forest offers a place of refuge and natural beauty where the element of surprise is all part of the experience’
The idea of nature as a spatial experience and a driver for architectural form was a question that ran through my academic work and has subsequently led to an obsession with a perceptual and evolving architecture. It is interesting that my time in the office has allowed me to both reflect and discover parallels that run through similar themes in the work of the practice. A pursuit for a “thicket-like” characteristic, which allows for shifts in spatial qualities and a variation of patterns that overlay like woven surfaces to define space are just some of the mannerisms that I have begun to recognise.
I compare my own attempt to generate a kind of place that is animated, brightening as you ascend towards the canopy when reading the blurred lines of the roof of the pavilion designed for a woodland park in Preston. The structure is designed as a number of layers of mesh to capture rain whilst creating a display of shadows that activate the building beneath. As a competition proposal, the structure was never fully realised yet it has been the ideas established during this process that still resonate today. By staggering the building between the tree density, the line of the pavilion is undefined breaking the traditional form of constructing space and allowing a new reading of the building and landscape. Particularly enlightening in the search for the enclosure of space is a fruition of a screen-like quality that works as a surface and also as a generator of it’s tectonic form.
The use of the screen as a ‘device’ in our architecture allows elements to become not only separators of rooms or the external environment but also actuators for unique and unimagined spatial experiences. In search of this architecture is an attempt to purposefully discover a different architecture and an unplanned result that wouldn’t necessarily be reached through something un-natural.

In February 2015, Benni was named as one of the nation’s up-and-coming designers and ‘One to Watch’ by the Design Council to represent the future of British design. His project the ‘City of Forests’ looked at beautifying Detroit through reforestation strategies to promote a denser, greener and more sustainable future in which timber becomes the main economic output. As Detroit continues to struggle with the effects of massive industrial changes, this more positive image of vacancy as an asset opens new discussions about the future post-industrial city.
