A well-designed basement shouldn’t feel like an afterthought. Ceiling heights, mechanical systems, lighting, flooring, insulation and the layout all affect how comfortable the finished space feels.
We plan each basement around the existing home and how you intend to use the space. Whether that’s additional living space, a home theatre, gym, guest suite or a completely separate secondary unit.
Where existing conditions create challenges, we look for practical ways to work around them rather than allowing ducts, bulkheads and utilities to dictate the entire layout.
Legal basement suites are becoming increasingly popular across Ontario as homeowners look to create rental income, accommodate extended family or make better use of their existing space.
Our team understands that converting a basement into a legal secondary suite involves more than adding a kitchen and bathroom.
Depending on your home and municipality, the project may require zoning considerations, building permits, fire separations, egress windows, interconnected smoke and carbon monoxide alarms, and upgrades to existing mechanical or electrical systems.
We work with our in-house design and engineering team to assess your existing basement, develop the required plans and manage the renovation from initial design through construction and final walkthrough.
Every property is unique, and we’ll help you understand the requirements for your project while delivering a finished suite that is functional, durable, and built with quality craftsmanship.
