Gloucestershire Garden Room by Robert Grace Architecture International Architecture Award Australian Institute of Architects

Jury citation

The jury was impressed by this impeccably detailed glass pavilion, which has been added to Woodchester House, a heritage-listed eighteenth-century Georgian mansion in Gloucestershire, England. The program for the room includes an entry, bathroom, laundry and living area with a fireplace inset into a stone wall, all of which is linked by a twelve-metre-long gallery to an existing outbuilding that adjoins the main house and contains a kitchen and dining room. The Garden Room makes innovative use of a glass roof resting on glass beams in the linking gallery, which gives the structure almost complete transparency. Within the Garden Room itself, thin blade concrete columns support a concrete roof, and glass is cleverly used again to emphasize the idea of a solid parasol placed next to a concrete wall. Impossibly tall (five-metre-high) glazed doors then slide away at the pavilion’s corners, dissolving any sense of intrusive mass. This project demonstrates a deft blend of high technology and contemporary materials with existing stone walls and framed views of a garden landscape. It is a compositional gem.
