In 2015, 5468796 was shortlisted for an invited competition to design a 200,000 s.f. mixed-use scheme for a former industrial site on Ottawa’s Chaudiere Island. The project scope included a 20-storey residential tower, office and retail space, underground parking and the integration of two existing warehouse buildings. Proponents were asked to tie into an existing community masterplan while maintaining social and environmental sustainability as a high priority.
Permeability of the ground plane became an important driver for the planning strategy. By breaking down the podium’s mass into simple blocks and organizing them around pedestrian routes and the existing heritage buildings, the design increases points of contact between street and building, old and new, residents and visitors, resulting in a rich and memorable every day experience. Furthermore, the separation of the lower blocks provides a variety of entrance points and creates a diverse array of outdoor rooms, while increasing retail frontage and drawing natural light to the podium’s core. Inspired in part by Windmill’s desire to create a complete community, and in part by our belief that shared public spaces are essential to the quality of life in cities – particularly in tall buildings – the amenity spaces become part of the public domain, starting from the ground floor up and weaving upward through the building like a vertical streetscape.
