Homes in Toronto range from downtown condos and semis, post-war bungalows, and century homes, and each brings its own considerations for home additions. Bild Quote connects you with verified local contractors who handle from second-storey builds to garage conversions and room additions. Most Toronto home addition projects cost $75,000–$250,000+ and take about 3–6 months once work begins — though your final price depends on scope, materials, and finish level.
We match homeowners across Toronto — including the Beaches, Leslieville, High Park, Roncesvalles— with contractors who know the area's homes and permit requirements. Older Toronto homes often need knob-and-tube rewiring, and heritage or laneway rules can apply — experienced local crews plan for both.
We also serve nearby North York, Etobicoke.
