Can You Help With Finding A Lot In Ottawa?

We assess each lot for soil conditions, drainage, zoning compliance, setback requirements, and buildability before you commit. We even maintain a list of large lots currently available for custom home projects.

Do You Offer Financing Options For Custom Home Builds?

Yes. OGC offers special financing options for qualifying custom home builds, including staged payment plans aligned to construction milestones. This means you're not carrying the full cost of your build upfront, payments are tied to design completion, permit approval, and construction phases. Ask us about current financing terms when you book your free consultation.

Will My Custom Home Be Energy Efficient?

All OGC custom homes are built to or above Ontario's current building code energy requirements. We offer a range of energy-efficient upgrades including triple-pane windows, spray foam insulation, high-efficiency HVAC systems, heat recovery ventilators (HRVs), solar-ready electrical panels, and EV charging rough-ins. These upgrades reduce your long-term utility costs and qualify your home for available government energy rebates.
