The University of Cambridge has announced the winner of a design competition for a flagship feature on its science and technology campus at West Cambridge.

The competition asked architects to come up with a design for a new colonnade; or covered walkway, that will form the link between two social ‘squares’ on the site. London based firm, Marks Barfield Architects (MBA), designers of the London Eye, won with an innovative response to the brief.

The colonnade is a central architectural feature of the original masterplan for West Cambridge, linking the East and West Forums. The masterplan has been drawn up by MacCormac Jamieson Prichard and is designed to meet the University’s needs through a sustainable environment.

An important example of sustainability is the incorporation of photovoltaic fuel cells into the roof of the colonnade. It will be the first of its kind in the UK and will form part of the overall infrastructure on the site. A partnership between the University, consulting engineers Whitby Bird & Partners and the Municipality of Gotland, is proposing to develop photovoltaics in Cambridge and Sweden as an EU Hydrogen Economy demonstration project. The University’s Estate Management and Building Service (EMBS) is managing the project as part of the West Cambridge development.

The hydrogen project combines three technologies - photovoltaics, electrolysers and fuel cells. The process converts sunlight into electricity, which is then used to split water into hydrogen and oxygen. The hydrogen is then stored and used to power a carbon free bus.

David Marks, Director of MBA, commented on his winning submission:

"The idea for the colonnade design was inspired by the vernacular tradition of lightweight solar-shading canopies, filigree structures, and the latest photovoltaic technology. Three ribbons of solar panels gently undulate along the length of the 400 metre long structure.

"The ribbons are supported on a highly efficient modular structure that defines the space and creates the colonnade. Because the ribbons undulate alternately and overlap in plan, they create 'gaps' which allow views out from the future adjacent buildings whilst providing shelter from rain and sun."

Marks Barfield Architects is the practice behind the creation of the London Eye. It was founded by husband and wife team Julia Barfield and David Marks and has over 10 years experience of designing buildings that are functional, elegant and enjoyable to use. In 2001 it was awarded the Architectural Practice of the Year Award.

Colin Saunders, Project Manager for EMBS said:

"The colonnade is a integral part of the West Cambridge infrastructure. Whilst the form of the structure enhances the overall look, it also contributes to the sustainability of the site and to the work carried out at the University into photovoltaics and the hydrogen economy."

Richard MacCormac of MacCormac Jamieson Prichard who chaired the judging panel said:

"The scheme has the potential to create an iconic image for the West Cambridge site."

Work is due to start on site at the beginning of next year and is expected to be complete in September 2003.
