Service 01
Custom House Building
Foundations, framing, structural work, new builds, and additions.
Overview
Built with intent
A custom home is one of the most personal projects you will ever take on. OTO Construction builds new homes and additions from the ground up, with careful planning at every stage, from excavation and foundations through framing, envelope and interior finishes.
We work alongside your architect or designer, or help you assemble the right team, so the home that gets built is the home you imagined.
Capabilities
What we do

Interior Finishing
Drywall, trim, millwork, flooring and fixture installation through to completion.
Benefits & Considerations
Plan it right
- Lot & Zoning
- Setbacks, height limits and conservation authority rules can shape what is possible on a property. These should be reviewed early.
- Permits
- New homes and additions in Ontario require building permits. Timelines vary by municipality.
- Seasonal Timing
- Foundation and framing schedules are planned around Ontario winters and spring thaw.
- Budget Clarity
- Defining finishes and allowances early keeps the budget predictable throughout the build.
