Acton Ostry Architects

Limberlost Place is a ten-storey, tall wood academic building that is currently under construction on the George Brown College Waterfront Campus in Toronto. This first-of-its-kind mass timber building features a revolutionary exposed cross-laminated timber and glulam structure with a striking, angular rooftop silhouette. A triple-height atrium with a series of cascading seat-stairs will display learning activities to the surrounding neighbourhood. Innovative net zero-ready building components include a thermally-efficient prefabricated building envelope, deep lake water cooling, rooftop photovoltaic panels and two soaring natural ventilation solar chimneys that will draw air up and through the building. The project is a collaboration of Moriyama & Teshima Architects and Acton Ostry Architects.

The design is a very clean execution of the program, targeting net-zero energy, achieving resiliency, and using smart-building technologies in a mass timber structure. The project presents the possibility of longer span wood structures becoming a viable option in the mass wood market.
