OGC designs and builds one-of-a-kind homes across Ottawa, with architecture, engineering, and construction under one roof, a fixed price, and Ontario's Tarion new home warranty protecting the biggest investment of your life.
A custom home is not a floor plan pulled off a shelf. It is designed around your family, your lot, and the way you actually want to live, then engineered and built to a standard that lasts for generations. That is the only kind of home OGC builds.
As a true design-build firm, we bring architecture, interior design, engineering, permits, and construction under one roof. One team, one fixed price, and one dedicated project manager carry your home from a blank lot to the day you get the keys.

Step onto two of our Ottawa custom home projects, from architecture to the finished build.
Building a custom home is a long partnership, so nothing is left to chance. Here is the design-build process OGC follows from an empty lot to the day you move in.
We start with your vision and your budget, and whether you already own a lot or are still looking. We assess the site, servicing, and zoning so you know what is buildable before you invest in design.
Our in-house architects and designers shape your home around how you live, then bring it to life in photorealistic 3D so you can walk it and refine it long before we break ground.
We produce the stamped engineering, handle the full City of Ottawa permit and zoning process, and enrol your home in Ontario's Tarion new home warranty program.
Before we build, you get a detailed, fixed-price contract covering the full scope with clear allowances. The number you approve is the number you pay, backed by our price-match guarantee.
One dedicated project manager runs your entire build with our vetted trades, keeps the site clean and secure, and keeps you updated at every milestone from foundation to final finishes.
We walk your finished home with you, complete the final inspection, and hand over the keys along with your Tarion new home warranty and our own workmanship guarantee.
Take a self-guided 3D tour of a custom home we built, and walk every room at your own pace.
For over a decade, OGC has been one of Ottawa's most trusted luxury custom home builders and the city's most reviewed design-build firm, with 200+ verified reviews across Google, Houzz, and HomeStars.
Most luxury homes pass through an architect, then a separate builder. We do both in-house, so your design is grounded in what we can actually build, on budget, with no gaps between drawing and delivery.
A single project manager runs your entire build and stays reachable by phone or text the whole way through. On a project this large, that single point of accountability is everything.
Every home starts with full 3D renderings and virtual walkthroughs, so you experience the space and finishes before a single footing is poured. Change it on screen, not on site.
A custom home is too big to leave open-ended. You get a fixed-price contract with clear allowances and disciplined change management, backed by our price-match guarantee.
Every OGC custom home is enrolled in Ontario's Tarion new home warranty, with statutory coverage of up to seven years, plus our own workmanship guarantee on top.
OGC is a member of the GOHBA, Tarion, RenoMark, CHBA, and the Ottawa Chamber of Commerce, and has been named Ottawa's Small Business of the Year. Our work has been featured on CTV, HGTV, and in Ottawa press.
A sample of custom homes we have designed and built for clients across Ottawa and the surrounding region.
A custom home is the most complex project a homeowner ever takes on. These are the things we manage so you do not have to.
Not every lot is equal. Servicing, soil, slope, mature trees, and zoning all shape what you can build and what it costs. Whether it is a serviced infill lot, a teardown, or rural land, we assess it before you commit so there are no expensive surprises after closing.
A custom home has to satisfy your vision and the City of Ottawa's zoning at the same time, height, setbacks, and lot coverage. We design to both, and when a design calls for it, we manage the minor variance through the Committee of Adjustment.
A build that spans a year will pass through an Ottawa winter. We sequence excavation and the foundation to beat the frost, and keep the home weather-tight through every season so the schedule and the quality both hold.
Custom projects are where budgets slip, through vague allowances and uncontrolled changes. Our fixed-price contract, transparent allowances, and disciplined change management keep the final number close to the one you approved.
A new home in Ontario is protected by the Tarion new home warranty, with coverage that runs up to seven years for major structural defects. We enrol your home and add our own workmanship guarantee, so your investment is protected long after you move in.
Custom homes are priced by size, finish level, and site, and the figures below are for construction, not the land. Here is the range Ottawa clients are working within.
Square footage, ceiling heights, rooflines, and architectural complexity are the foundation of the budget. A larger or more intricate home costs more to engineer and build.
This is where luxury lives, and where budgets move most. Custom millwork, premium kitchens and baths, integrated technology, and high-end materials all shape the final number.
Servicing, soil conditions, slope, and whether a teardown is involved all affect cost before the home itself begins. A tricky site can add meaningfully to the build.

The questions Ottawa homeowners ask us most before building a custom home.
Custom homes in Ottawa generally run about $400 to $600 per square foot with premium finishes, and $600 to $800 or more per square foot for luxury builds, which puts a typical luxury custom home around $1.5 million and up, excluding land. The biggest drivers are size, finish level, and the site. Try our custom home cost calculator for a number tailored to your project.
Most custom homes take roughly 12 to 18 months from the start of design to move-in, with design and permitting taking several months before construction begins. Larger or more complex homes take longer. We give you a realistic schedule before you commit.
Both. If you already own a lot, we build on it. If you are still looking, we help you evaluate lots for what they will actually cost to build on, because servicing, soil, and zoning can make two similar-looking lots very different.
Yes. Teardown and infill builds are common in established Ottawa neighbourhoods, and they let you build a brand-new custom home in a location you already love. We manage the demolition, servicing, and any zoning approvals as part of the project.
Yes. Every new home in Ontario is covered by the Tarion new home warranty, with statutory protection running one, two, and up to seven years depending on the type of defect. We enrol your home in the program and back it with our own workmanship guarantee.
Yes. We build to a detailed, fixed-price contract with transparent allowances, so you are not exposed to the open-ended costs that derail so many custom builds. Any changes are documented and priced before they happen, and our price-match guarantee stands behind the contract.
Either way works. Some clients want a fully bespoke design from a blank page, while others start from a layout they love and tailor it to their lot and lifestyle. We meet you wherever you are on that spectrum. Explore our home design approach to see how we start.
