This glazed pavilion for 28 computer students at the German School is oval in plan and is located in the grounds of the Grade II*-listed Douglas House, London. The eaves-less roof is supported on four internal columns and the floor is raised to provide slightly pressurised air to the room and to enable changes in cabling to the students'desks. The optimum configuration of desks produced the oval plan shape. The external skin is made up of building-height glazing units, part-transparent, part-translucent.The latter have the new Swedish Moniflex transparent insulation, the former have glare control blinds and glare treatment. The M&E consultant for this stack-effect system is Waterman Gore Partnership, the structural engineer is Whitby Bird and the cost consultant Davis Langdon Everest.
