Meet Gravity Architecture

Gravity Architecture grew out of Inertia Residential Design, a Calgary studio started by Stephen Barnecut and Trent Letwiniuk after the two worked together at Alloy Homes. They incorporated Gravity Architecture Corporation in 2014 to take on larger buildings, and by 2018 Gravity had become the main practice while Inertia kept handling small multi-residential and missing-middle work.

The firm runs offices in Calgary and in downtown Vancouver at 1199 West Pender Street. Jim Vasto, an AIBC-registered architect, leads the Vancouver office and is the BC point of contact. Stephen Barnecut runs the Calgary side. The team has grown to more than 20 people across both cities.

On the multi-family side, the firm designs duplexes, fourplexes, townhouses, and rowhouses. Their stated approach is to cut cost where the code allows it, by minimizing firewalls and sprinkler systems where a design can avoid them, while keeping each unit livable.

BC projects in their portfolio include Mount Pleasant 8 (an eight-unit townhouse project), Mills Road Townhouses, West Kelowna Towns, Capital Hill townhouses, and several mixed-use buildings in Langley and on Joyce Street in Vancouver.

Why work with Gravity

01

A studio set up specifically for missing-middle work

Their Inertia Residential Design arm focuses on duplexes, fourplexes, townhomes, and rowhouses, separate from the firm’s larger buildings. That means a multiplex project is core work, not a side job squeezed in between high-rises.

02

Cost discipline written into the design approach

The firm says it works to minimize firewalls and sprinkler systems where the code allows. On a fourplex, those two line items move the budget a lot, so designing around them early matters.

03

Jim Vasto runs the Vancouver office and is registered with the Architectural Institute of BC. Local registration matters because a BC permit set has to be sealed by an AIBC member.

Frequently asked questions

Does Gravity Architecture design small multiplexes, or only larger buildings?
Both. The firm handles larger residential, commercial, and mixed-use buildings, while its sister studio, Inertia Residential Design, focuses on duplexes, fourplexes, townhomes, and rowhouses. A small multiplex falls under that missing-middle line of work.
Do they have an architect registered in BC?
Yes. Jim Vasto, an architect registered with the Architectural Institute of BC (AIBC), leads the Vancouver office. A BC building permit set has to be sealed by an AIBC member, so local registration is required for the drawings to be submitted.
How can they keep multiplex costs down?
The firm states it tries to minimize firewalls and sprinkler systems where the building code permits, since those are two of the larger cost items on a small multi-family building. Ask them early in design whether your layout can avoid them.
