Attic Renovations & Conversions in Toronto and the GTA

Most full attic conversions typically range from $120,000 to $230,000+, depending on the size, structural requirements, dormers, bathrooms, and level of finishes. Simpler projects may cost less, while complex structural conversions can exceed this range. Project-specific pricing is provided once the scope and requirements are established.

We assess your attic first and advise on the most practical and cost-effective options.

Attic (above-grade) secondary suites are permitted across most of the GTA under the same zoning rules as basement suites, provided they meet Ontario Building Code requirements for ceiling height, fire separation, egress, and independent systems where required. We design and build to these standards so the suite is legal and usable.
