Winchester & Fletcher Houses
A flagship commercial project, Winchester and Fletcher Houses offer a total of 50,500 ft² of new office and laboratory accommodation on the Oxford Science Park. CampbellReith provided structural engineering services for the three storey buildings.
The houses with the undercroft car park are linked by a covered entrance space and occupy a lakeside position. Each building has been designed to accommodate either a single occupier or alternatively can be divided into self-contained floors. The superstructure comprises a steel frame and is clad in a glazed curtain walling system with ceramic tiles at the ends of each building.
The feature lakes on the site form part of the stormwater infrastructure for the Science Park, collecting rainfall from this development and adjacent plots. Whilst this provides an interesting and diverse landscape setting, the lakes have also been designed to attenuate a 1:100 year storm event.
The Danby building located at the gateway of the Oxford Science Park offers 55,700 ft² of office accommodation. The building features a lightweight Brise Soleil, reducing internal heat by deflecting sunlight.
The structure, with its distinctive oversailing roof, has three-storey and four-storey wings joined by a central atrium. Following a feasibility study, CampbellReith proposed a Slimdek light steel frame as the most economical solution. This avoids the use of downstand beams and offers complete flexibility to integrate mechanical and electrical services.
3D computer modelling software accelerated the design process. CampbellReith carried out wind tests to accurately assess the wind loads acting on the complex geometry of the oversailing roof. The results were put into the model to complete the design.
