Brief
To convert the main roof into a habitable loft. To create an open-plan space to the existing rear annex structure at ground floor level by constructing a single-storey side extension and removing the existing flank wall. To construct a new garden studio building to the rear boundary.
Aim
To achieve a sense of interconnection of the garden studio with the main building but in a manner that is secondary to the feel of a garden space. Achieve an open-plan arrangement within the main house and to introduce large areas of glazing to the walls and roof for natural light whilst maintaining high thermal properties. To be designed and detailed to attain Party Wall award and Building Control approval in the shortest possible time.
Solution
The garden studio was excavated to a lower level than the main building and reinforced concrete retaining walls and foundations were used to support a timber framed superstructure. Structural steel was used to open-up the rear annex and to frame the glazed walls to side extension. Engineered timber joists formed the new loft floor supported by structural steel beams. Roof modifications in timber.
