expertly handled.
Double your living space without losing your yard. We manage structural engineering, permits, framing, roofing, and interior finishing — all under one contract.
Extend a kitchen, enlarge a master bedroom, or add a mudroom. Bump-outs are one of the most cost-effective ways to gain meaningful square footage.
Transform an underused garage into a home office, gym, studio, or legal suite. We handle insulation, HVAC integration, electrical, and finishing.
Bring the outdoors in with a properly built sunroom addition — insulated, permitted, and designed to last through Durham Region winters.
A detached garden suite adds a fully independent living space to your property. We navigate the permit process, foundation work, and full build — including utility connections.
We handle the complexity.
You enjoy the result.
We meet at the property, discuss your goals, and give you an honest assessment of what's structurally and financially feasible. No pressure, no obligation.
We work with your designer or refer you to one, then manage the full permit application with Durham Region's building department. We know what inspectors require.
Foundation, framing, roofing, mechanical, and finishing — all coordinated under one contract with our trusted trade partners. You deal with one person throughout.
We see the project through to final inspection and occupancy permit. You don't get keys until everything is done right and signed off.
