The timber roof is now in place on our ground floor extension at Mount Pleasant Villas in Crouch Hill, and the new room can be read as a whole for the first time.

Exposed rafters span the room, with a line of rooflights set between them. During our site visit these cast bands of sun across the new blockwork wall. Along the other side, a timber clerestory frame rises above the existing wall, and a new steel frame marks the opening into the original house.

We walked the space with the contractor, checked the post and rafter connections and sketched out a detail on site. The rafters will stay exposed in the finished room, so the quality of these junctions matters.

Next on site: roof covering and glazing to the garden opening. We will share more as the project progresses.
