A Passion For Sustainable Building Design

It is this passion that led to the inception of GNAR Inc. a building design firm focused on bringing clients vision to life while also having a positive impact on the environment.  The desire became reality in 2016 when the company was established in the mountain town of Whistler, BC. Ongoing education in areas such as Energy Efficiency, Energy Retrofits, Passive House Design, Net Zero, and Energy Positive Building Design has allowed the GNAR Inc. team to become experts in sustainable building design with a desire to see it become the building design standard in the Sea to Sky corridor and beyond.

Our Mission

To Have Every Renovation, Addition, and New Building Design Be a Sustainable One.

Mark Kavanagh

Lead Sustainable Home Designer

Mark, who is our Lead Sustainable Home Designer, hails from Ireland.  Having graduated with a Masters in Architecture from the University of Dublin in 2019, he decided to trade in his Gaelic speaking ways and his galoshes for ski boots and started living in the mountains. He found solace in the rainy spring and fall days and called Whistler home.  He has since moved back to Ireland due to COVID but will be returning “home” soon.  He has a passion for sustainable design practices, the environment and maintaining a low eco-footprint. Mark has the skills to pay the bills with a background of industry know how as well as hands on experience which makes him a builder’s dream designer.
