The new 100 m long glass Orangery maintains the historic function of the 15thcentury site whilst creating an enclosure built to the architectural specifications of the 20thcentury. The construction is designed as a shell formed by a semi circular diagonal stainless steel mesh glazed with toughened laminated glass. The mesh is stabilised by glass and metal cross walls and supported at the back by a triangular truss which is to transfer both the horizontal and vertical forces of the enclosure. The internal spaces are column free yet function in three individual zones for differing climatic conditions. Automated roller blinds provide shade in the summer and insulation in the winter.
