British Columbia is on the brink of a significant building code update that could reshape urban development. Housing Minister Ravi Kahlon announced on July 4, 2024, the plans to allow single-exit stairways (SES) in buildings up to six storeys, based on a report from engineering firm Jensen Hughes. This change promises to enhance safety, design flexibility, and environmental sustainability. Traditionally, the law has only permitted one staircase for buildings less than two or three storeys tall in the province and much of North America and required at least two exit stairways for buildings over three storeys tall.
SES buildings optimize space by wrapping units around a central staircase, allowing for more natural light and better ventilation, creating more spacious and comfortable living areas even in smaller lots. These buildings can also reduce their carbon footprint and improve airflow, contributing to more sustainable urban development and aligning with eco-friendly construction practices. Additionally, SES buildings allow for more units on less land, providing larger, family-friendly units in urban areas and helping to meet the demand for affordable housing.
Vancouver-based architect Bryn Davidson, a long-time advocate for SES, expressed his excitement about this development. Davidson, co-owner and lead designer at LaneFab Design, highlighted the potential of SES to transform both the form and function of multi-family housing. He noted that this change could offer a new design choice in North America.
The proposed changes to B.C.’s building code are expected to be introduced in the fall of this year, following further engagement and consultation. This move reflects an evolving approach to building regulations, driven by technological advancements and the need for sustainable development.
At WeConstruX, we are excited about the possibilities that SES buildings bring to the future of construction and urban living. We support this initiative and look forward to seeing how these changes will shape the landscape of B.C. and beyond. Stay tuned for more updates on this and other groundbreaking developments.
