Equilibrium Consulting principal Robert Malczyk may be the Engineer of Record on Shigeru Ban’s tall downtown Vancouver timber project, but he’s more interested in the humble mid-rise. The mid-rise, not the attention seeking wood skyscraper, he argues, will ultimately transform the way we see wood-frame and mass-timber construction. “Combining energy efficiency and mass timber is my personal passion,” says Malczyk. “Of course, it’s nice to be involved in these [tall] buildings, but I think the biggest change we can influence is in mid-rises.”
Shigeru Ban’s Terrace House in Coal Harbour is one of a number of wood skyscrapers underway in the global race to the top. The first twelve stories will be constructed with traditional concrete and steel, while the remaining seven will feature exterior wood elements and floor plates cut from timber. The plan is for all of the wood to be sourced locally.
According to Malczyk, mid-rise buildings— anywhere between five and twelve storeys—built from readily available B.C. wood products are incredibly energy efficient, and will put taller wood construction firmly within the mainstream. North American developers are realizing this, and in many cases, the combined use of light-wood frame and mass-timber construction can offer economic advantages over traditional steel and concrete.
It’s not only cheaper, but prefabricated mass timber means less debris and noise, which makes it less likely to disturb nearby residents. In North America, we already have the technology to build a mid-rise in the space of a week, says Malczyk. “Developers are doing it now for very economical buildings, not the high end,” he says. “It’s more of a base market with mass timber, which is huge progress.”
His founding partner at Equilibrium, Eric Karsh, concurs. For the last couple of years, the push for residential and office mid-rises has gained momentum, with dozens of B.C. buildings in the design, permitting, and building stages—largely because the development industry is on board, says Karsh. “A few years ago, we were only doing demonstration projects. Now we are doing developer-driven projects. They didn’t want to be the first to do it, because issues needed to be resolved. I think we’ve crossed that barrier.”
Located seventy kilometres east of Vancouver in the Fraser Valley, Abbotsford Senior Secondary School features wood as part of a major rehabilitation and replacement project.

For many, urban community and recreation centres are becoming a home away from home. Showcasing the beauty of wood, British Columbia (B.C.) forest products from sustainably managed forests are being used to help make these important facilities feel warm and inviting, enhancing well-being.
This 8,825-square-metre aquatic centre in the heart of Surrey looks ready to take flight, with catenary, undulating, glue-laminated timber cables that swoop skyward.
Read this interview with Scott Groves, who oversees design, construction, and operations of all civic facilities in Surrey, and find out how the province’s fastest-growing city is winning with wood.
Commercial and industrial buildings are incorporating more wood into their construction. Along with the strength needed to last in heavy duty applications, wood has its own unique advantages.
