A unique floating stair with character and a story
Private Residence (Floating Stair)
Architect: Architects Alliance
Client: Clemmensen & Associates Ltd.
Collaboration: Webb Yates Engineers
Project Type: Structural Engineering
This renovation project by Clemmensen Builders and Peter Clews of Architects Alliance perfectly combines a contemporary vision with a historic multilevel dwelling set in a ravine in the heart of Toronto. With charcoal basalt stone flooring, a white interior pallet, and soft tone wood floors dominating all levels, punched windows were reconstructed with floor to ceiling glazing inviting ravine and city views on the main level.
With such beauty, no one element of design could stand out amongst the others; however, the solid Basalt stone feature stair seems to do exactly that. With an initial design to cantilever treads off of the supporting masonry wall, PICCO Engineering was brought on board to bring our stone and structural engineering expertise and experience to strategize and present a bolder approach. Our true span, post-tensioned, and solid stone “floating” solution was proposed and enthusiastically accepted. In collaboration with Webb Yates (London, England), full execution including material supply, engineering, installation, and quality control was provided.
A true one of kind stair worthy of this storied home and its peaceful setting.
