Portobello Garden Extension

The brief was to for a garden room extension to an existing listed terraced townhouse.

A key issue was the need to bring light into a dark corner of the site. The decision to build off the existing party wall and the incorporation of clerestory windows which reflect light down off the sloping ceiling, were responses to this.

Planning and Listed Buildings were insistent form the outset on all of the new walls being built on stone to match the existing. The extension’s simple material palate of carefully detailed stone, lead, slate and painted timber are intended to satisfy these conditions without being reduced to copying.
