This 1970's home had had a number of small additions and extensions at ground floor level, and the proposed development involved the construction of a new master bedroom and ensuite at first floor, and conversion of the rear of the garage into a playroom at ground floor.
To avoid costly demolition and re-building of the existing single-storey ground floor structure, the first floor extension was carefully designed to limit the additional load to be applied to the existing foundations and single-skin brick walls.
Timber frame construction, with pre-fabricated roof trusses were selected to reduce loads and for speed of construction.
