Founder
Maurice Viens
Inventor of the MV3 system. Maurice has spent almost a decade conceiving, designing, testing and commercially validating the morticed OSB modules at its core.
The company
A fabrication shop, and a conviction about the wall.
MV3 Construction System Ltd. is a Calgary company developing what it believes is the first true innovation in residential timber wall framing since platform framing replaced balloon framing almost a century ago.
Why we build the envelope this way.
01
The envelope decides the building
Heating demand, comfort, moisture and acoustics are all settled by the wall before anything mechanical is chosen.
02
Green by construction, not by label
Insulated OSB modules do the unglamorous work of energy efficiency: fewer thermal gaps, less material waste, fewer vehicle movements to site.
03
Designed for the trades that exist
Experienced framing labour is getting scarcer, not cheaper. Our modules are made so a builder can deliver an energy-efficient envelope with the crew they actually have.
The principals
A father and son, one system.
MV3 Construction System Ltd. is a Calgary company run by Maurice and Colton Viens. Both are reachable directly through the inquiry form below.
Principal
Colton Viens
Works alongside his father to take the system from proven concept to commercial production, and presents MV3 to builders, designers and industry audiences.

Collaboration
No one builds a green envelope alone.
MV3 works with other green-build innovators by design — sharing detail, testing and specification work rather than competing over it.
Cross-design partner
BTRboard Inc.
BTRboard makes exterior insulated wall sheathing in Canada — a 7/16" OSB skin over a 1 3/16" medium-density polyurethane foam core with a fibreglass facer, adding up to R-8.75 to a wall system without thickening the assembly. We are in the early stages of cross-design work pairing their insulated panels with MV3 modules.

SSRIA
The Smart Sustainable Resilient Infrastructure Association has backed MV3 with advice, promotions, networking opportunities and grant funds — support that has carried the system from concept to its first commercial build. We are grateful for it, and for the standard they hold the industry to.

If you make a low-carbon product, material or system for residential construction, we would like to hear from you. We are actively looking for partners to explore integration, joint testing and shared project work.
Affordable housing initiative
Building smarter, not just cheaper.
Canada's affordability problem is not mainly a problem of construction cost. Speculative land pricing, profit margins and ever-larger mortgages inflate what homes cost. MV3 believes the answer is systemic change: policy reform, community involvement and support for energy-efficient housing communities that put people before profit.
After almost a decade of developing and validating wood-frame construction, MV3 sits at the hub of an informal network of innovators, architects, designers, testing agencies and municipal authorities. The vision is to draw that group together to pilot proof-of-concept affordable communities.
01
Capped returns
Funding begins with socially-conscious micro-investors pooling resources, with their returns capped at a modest rate.
02
A 10% margin ceiling
MV3's own profit margin on the initiative is limited to 10%. Anything beyond that is reinvested in research and development.
03
Unlocking public funding
Private capital is used to unlock federal grants and subsidies for affordable housing, alongside community engagement.
