Ontario needs housing.
You have the land and the funding.
Now you need the speed.
The biggest barrier to building today isn’t demand, it’s delivery.
Traditional construction timelines are too slow, tying up capital for years before a single unit generates revenue.
In many parts of Ontario, developers face another challenge: limited viable construction options. OneBuild helps developers build where others can’t. Or won’t.
Build smarter. Build faster.
Up to 55% faster delivery, with fixed pricing and no surprises.
In this market, speed isn’t just an advantage, it’s a necessity.

Not all Modular is the Same
Most “modular” construction isn’t fully modular. OneBuild delivers complete, ready-to-install modules.
Most modular systems are panel-based, delivering walls, floors, and structure while leaving the majority of work to be completed on-site. OneBuild is fully volumetric, with interiors, systems, and finishes completed before delivery.
Built for Speed
Designed to keep your project moving forward.
With OneBuild, key phases happen at the same time, not one after another. We get you to occupancy months sooner than traditional construction, often reducing timelines from 20 months or more down to 8.
Faster timelines mean faster to revenue, reduced carrying costs, and projects that move when they’re supposed to.
Modular by Design
Designed to flex, scale, and adapt. Build what your project demands.
We built our modular system with flexibility in mind. By combining and configuring modules, we can deliver a wide range of housing types, from multiplexes and townhomes to mid-rise apartments and specialized housing.
Whether you’re building a handful of units or a large-scale development, the approach stays consistent: efficient, repeatable, and built for speed.
Multiplex & Low-Rise
Duplexes, triplexes, fourplexes, and small multi-unit builds designed for efficient density and fast approvals.
Apartments & Mid-Rise
Purpose-built rental and multi-unit buildings, configured for scale, consistency, and shorter delivery timelines.
Specialized Housing
Duplexes, triplexes, fourplexes, and small multi-unit builds designed for efficient density and fast approvals.
Stop waiting. Start Building.
