It is looking for landscape architects or architects to renew the kilometre-long covered pedestrian walkway designed in the 1960s to provide a way to walk across the whole of the campus while being mostly protected from the weather.
The Spine was designed to follow the natural gradient of the land by the original architects and master planners, Shepheard Epstein, which also left portions of the walkway open to the sky to let in natural light.
Lancaster University director of facilities, Mark Swindlehurst said: "We are looking for an innovative team capable of rejuvenating The Spine and re-presenting it as a space that knits together an array of different buildings, external landscapes and addresses various building frontages and entrances.
"We want to create an inspirational space where people learn, work and live as well as go about their daily business. The university fosters a sense of community cohesion and The Spine should facilitate this."
The Royal Institute of British Architects (RIBA) is managing the competition process and a shortlist of five teams will be invited to develop their concepts in response to the university’s outline brief. An equal honorarium will be paid to each of the five shortlisted teams invited to participate in the design phase of the competition.
Teams have until 2pm on May 12 to enter. Visit the competition link for more information.
