The basement was formed in a top down sequence, with slender reinforced underpins formed in two/three stages, and sequentially propped as the dig progressed to the lower levels.
Existing cantilevered stone staircases within the property were in poor condition, with these needing to be repaired and protected during the works.
The finished building incorporates a spacious pool room, with natural light provided via a full length roof light within the planting above. Also within the lower levels are services kitchen, cinema room, and gym, all fitted out to the highest standard.
