Advantages of Mass Timber Construction
Mass timber construction, a building technique using large, solid wood panels, columns, or beams, has been gaining popularity for its strength, sustainability, and efficiency. Unlike traditional wood construction, mass timber offers high strength ratings while being significantly lighter in weight. It performs just as well as concrete, if not better, and has a more positive environmental impact.
Vancouver City Council's Support
Vancouver City Council recently took steps to encourage and support mass timber construction. The proposed Mass Timber Policy for Rezonings would allow additional height and density for developers who utilize mass timber. This incentive aims to remove barriers and increase the adoption of this innovative building form. Projects taking advantage of the incentives must still meet area plan requirements and consider factors such as urban design, view cones, and shadow impacts.
Increased Allowances and Support
For projects not requiring rezoning, the City of Vancouver currently allows a 6% height increase for mass timber construction. Staff recommend increasing this allowance to 10% and making it an outright, non-conditional process. Additionally, the city plans to provide consultation support during the development inquiry stage to mitigate the uncertainty of the permit process for projects using mass timber construction.
Provincial Support and Adoption
The provincial government recently announced raising the 12-storey limit on mass timber buildings to 18 storeys under BC's building code. The aim is to expand the use of mass timber in taller buildings and create stronger communities. The City of Vancouver is set to adopt this change and also plans to allow mass timber on firewalls and lot line walls later this year.
Conclusion
By combining the efforts of the provincial government and Vancouver City Council, it is evident that mass timber construction is set to become mainstream in British Columbia. The recognition of its benefits and the removal of barriers through increased allowances and support will contribute to a more sustainable and resilient built environment. As more developers and architects embrace this innovative technique, we can expect to see a surge in mass timber buildings throughout the province!
