Planning permission received for a contemporary glazed extension to a Grade II listed early 18th century brick and limestone house in Cheltenham, Gloucestershire. The design will create a modern open plan kitchen dining space which opens onto the garden with thin aluminium framed sliding glass doors. A thin green roof provides a lightweight structure floating over the glazed doors. The design provides a balance between old and new to offer a cohesive appearance This was noted by the Conservation Officer comments, ‘‘The design includes much detail and consideration regarding sustainability issues and of a high architectural composition which will represent a contrast of style from the main host building whilst still respecting the listed building in relation of form, scale and mass.’’
