oN5 Building Technical Bulletins

Innovative mass timber design in an urban infill office building

Located in the Mt. Pleasant neighbourhood of Vancouver—a community filled with architecture and design firms—oN5 is a demonstration project that combines high performance, mass timber construction, new approaches to insulative CLT assemblies and damage-resistant seismic design. The unique features of this project are also possible due to the delivery method used by the team which is based on multi-disciplinary collaboration.

There will be five technical bulletins regarding oN5. The Introduction and High-Performance Low Carbon Construction can be found below. Coming soon: Off-Site Construction; On-Site Construction and Project Delivery; and Regulatory Perspectives.



This technical bulletin provides an introduction to the innovative wood technology/design and construction methods used in this project.
