Whitby Basement Types & Considerations
New Builds in Brooklin
Brooklin's post-2010 homes have spacious unfinished basements — the most popular Whitby renovation. Typically 700–900 sq ft of high-ceiling space ideal for legal suite or family rec room.
1980s–1990s Homes (Rolling Acres, Blue Grass)
These homes have basements that were often partially started by previous owners. Full professional finish with proper insulation and vapour barrier is the most important first step.
