Willmott Dixon has a long track record of enhancing university estates to transform them into world leaders. Our expertise in this field was underlined when we took on the multi-million-pound contract to construct Kingston University’s Town House.
The vision was to create a front door to the community and replace the university’s old, 3000 sqm prefabricated temporary meeting and office space on Penrhyn Road with a 9,400 sqm bespoke, landmark building that complemented nearby architecture.
The design, which reflects the external cloisters seen in Northern European architecture, features a considerable amount of open space to create a real sense of fluidity. Alongside this, a matrix of interlocking spaces weaves together, creating secluded corners for study, collaborative working and community groups.
The contract was awarded to Willmott Dixon in December 2016 and construction started in April 2017. Due to its bespoke nature, the construction was extremely complex so great care had to be taken to ensure the lines of communication were open with our supply chain at all times.
We wanted this project to be BIM Level 2, so fortnightly design meetings were held between precast frame supplier PCE and mechanical and electrical specialists DES Group and CMB Engineering. Together the team was able to incorporate the completed M&E design within the frame immediately. These meetings continued throughout to manage clash detection.
The precast-concrete frame is integral to Town House’s design. Exposed concrete runs throughout the entirety of the building and there are no surface fixings meaning it is open to close scrutiny. Perfection was paramount — there was no room for blemishes or air pockets, which would have impacted on the sleek finish. This was one reason behind using precast concrete rather than cast in-situ reinforced concrete.
Initially we looked at how we could work around the design. There were a lot of onsite constraints as it is quite a small plot. We recognised quite early on that using precast concrete was the best way forward for the frame. Normally, one of the factors that helps sway the decision to use precast concrete is the amount of repetition through the design. However, at Town House there is very little repetition. Ductwork for services, pipes, cables and communications is cast within each structural member. There are hardly any two sections the same. The goodwill of our neighbours, avoiding disturbing residents and the day-to-day working of the university, as well as the speed of erection, were also much more attractive benefits of the precast solution.
Although the building is mostly precast concrete, in a nod to the building’s surroundings, there is a traditional hand-laid full brick finish to the cladding panels across the exterior elevations as well as sections of Portland stone.
The building is rated BREEAM Excellent for its sustainability and includes SUDS, underfloor heating, and roof gardens.
Town House was a hugely ambitious project — one we fully embraced. It’s testament to the team’s dedication that the original design has been realised to such exacting standards.
