The OHC platform is an open, modular set of layers that work together — and work independently. Adopt one layer or all five.
OHC operates as a public-interest stack. Each layer is open, interoperable, and designed to be adopted by any jurisdiction, Nation, or developer in Canada.
A national, openly licensed dataset of parcels, zoning, infrastructure capacity, and program eligibility — harmonized across jurisdictions.
A curated catalogue of code-ready typologies — from laneway homes and infill to mid-rise — with permit-ready drawings and manufacturing specs.
Zoning, building, and program rules encoded as queryable logic — so any parcel can be tested against any rule, instantly and verifiably.
Models and copilots that compose the layers above into useful answers — feasibility, scenario comparison, design fit, and approvals readiness.
A single, transparent pipeline from raw geography to a deliverable, financeable housing project. Every step is open, auditable, and reusable across jurisdictions.

BuildBlox is the AI/software layer that applies OHC’s data, standardized designs, and rules-as-code to specific sites and programs. It turns the commons into operational answers — for governments evaluating supply, for developers running pro formas, and for Nations planning long-term housing.

DASH — Digitally Accelerated Standardized Housing — turns the repeatable, technical parts of housing delivery into shared digital infrastructure: code-ready designs, prefabricated components, coordinated supply chains, and a common data standard. Founded by BC Housing with CMHC and the B.C. Ministry of Housing & Municipal Affairs, DASH is delivering homes across British Columbia today, and structured — non-proprietary, open, and free — so any province or territory can adopt it.
Recognized with CMHC’s 2025 President’s Medal for Outstanding Housing Research and the 2024 Building Transformations Design & Engineering Award.
From a parcel of land to a delivered building
Enter a lot, pull zoning and constraints, and generate an optimized 3D concept in minutes.
Start from code-ready blueprints and standardized unit layouts, then adapt to the site and community.
Match made-in-Canada components and suppliers before drawings are locked.
One model carries the project through approval, construction, and asset management.
Four connected stages, one continuous digital model — no re-drawing, no re-keying, no lost decisions.
The DASH toolkit
See the platform →Everything a project needs, in one place — the designs, data, and connections that used to live in a dozen disconnected places.
Where OHC fits
BuildBlox →OHC is not a DASH operator. We supply the upstream commons that lets the DASH toolset travel — parcel data, machine-readable bylaws, and adapters across public-sector housing programs, wrapped in BuildBlox as the application layer.
Proven in British Columbia · Built to travel
Delivering homes across BC today. Discussions underway in New Brunswick. Open by design so every province and territory can follow.
We work with provinces, agencies, Nations, and municipalities to onboard data, digitize bylaws, and stand up delivery tooling.
