Kopman Build designs and builds home additions in Brampton — rear additions, second-storey additions, side additions, and accessory dwelling units. Full permit management, single-contract delivery.
For most Brampton homeowners, adding square footage to an existing home is more cost-effective than moving. Brampton's newer tract and executive homes are good candidates for additions — they sit on lots with room to expand, and the existing structure can typically carry the load.
Home additions are one of the most complex residential construction projects. They involve foundation work, structural engineering, mechanical extension, waterproofing, and seamless integration with the existing structure. Kopman Build manages this as a single coordinated project, not a sequence of separate trades.
We handle permit applications, survey requirements, zoning analysis, and engineering coordination in-house. You don't need to manage consultants separately — we bring the complete team to every Brampton addition project.
Single or two-storey rear extensions that expand the main living floor and add kitchen, dining, or family room space.
Full second storey or partial pop-top additions that double the living area of a Brampton bungalow.
Narrow lot additions that expand the home's footprint within zoning setback requirements.
Attached and detached garage conversions into habitable living space, legal suites, or home offices.
Accessory dwelling units built at the rear of the property for rental income or multi-generational living.
Three-season and four-season sunroom additions built to Ontario Building Code standards.

Home addition costs in Brampton vary significantly by type and size. A rear addition of 300–500 sq ft typically costs $250,000–$450,000 depending on scope and finish. A full second-storey addition runs $350,000–$700,000+. These estimates include all hard construction costs but exclude soft costs (permits, engineering, architecture). We provide a detailed pre-construction estimate before commitment.
Yes — all additions that change the building footprint or add habitable area require a building permit. Additions involving foundation work also require a surveyor's report and sometimes a Committee of Adjustment application if the addition doesn't conform to current zoning. We manage all permits and consultants as part of our standard service.
A rear addition in Brampton typically takes 4–7 months from permit approval to completion. A second-storey addition runs 6–10 months. Permit acquisition adds 4–12 weeks on the front end. We provide a realistic timeline at the pre-construction planning stage, before any commitment is made.
