The Radisson SAS Hotel is a substantial new build four star hotel in the centre of Glasgow. Murray Dunlop Architects have created an iconic building behind a copper clad facade.  The reception, bar and lobby are within a five storey atrium punctured by a slate cube of rooms thrusting out from the main building.  Lighting features include a colour change on the roof beams of the lobby and a field of blue in the courtyard surrounded by glowing trees. In general, lighting follows the architecture with families of linear fittings flowing along the axes of the spaces.  The Radisson SAS Hotel won top prize at the 2003 Scottish Design Awards as the best commercial project and also the architecture grand prix award.
