Tantrum Urban Commercial Infill

Tantrum Urban Commercial Infill

The Tantrum building is a commercial infill Passive House project that will demonstrate the benefits of exceeding design and code minimums in what is typically an overlooked building typology.

The narrow 7.6-metre by 39.5-metre site sits in Revelstoke’s downtown core amidst heritage-era low-rise buildings. 

The three-storey building will house a ground-floor retail unit with offices above.

To contend with the region’s short building season, construction options were short-listed to either prefabricated or modular systems.

Ultimately, floor and roof panels using cross-laminated timber for the shear walls and wood fibre insulation were utilized to increase build speed and help achieve the Passive House performance goals.
