Mimico's lakefront streets are lined with 1930s–1960s bungalows and semis that are ideally suited to second storey conversions — and rapid gentrification means the neighbourhood now supports the investment. Kopman Build has been building second storey additions in Etobicoke since 1999, managing everything from structural engineering to City permits to final occupancy.
Mimico sits at the western edge of Toronto's lakefront, and its housing stock — predominantly one-storey bungalows and semis built between the 1930s and 1960s — makes it one of the strongest markets in the GTA for second storey additions. With lakefront proximity driving demand and gentrification reshaping the neighbourhood block by block, adding a full second floor is often the most financially sound decision a Mimico homeowner can make.
Older Etobicoke homes present specific structural considerations: foundations, load-bearing walls, and roof framing from this era often need engineering review and reinforcement before a second storey can be added. Kopman Build brings the experience to assess, plan, and execute these conversions properly — not as a theoretical exercise, but as contractors who have done it repeatedly in this neighbourhood and know exactly what to expect.
Dustin Kopman founded the company in 1999 after growing up in construction through his family's firm. Every project is led by someone who understands the craft, not just the contract.

A second storey addition on a Mimico bungalow typically runs $350,000–$650,000+ depending on the footprint, structural complexity, and finish level. Mimico's 1930s–1960s housing stock often requires upgraded foundation work and load-bearing reinforcement, which should be accounted for in any realistic estimate. Kopman Build provides a detailed line-item pre-construction estimate before you commit.
Yes. A second storey addition in Mimico requires a building permit from the City of Toronto. Depending on your lot coverage and proposed height, a Committee of Adjustment minor variance application may also be required. Kopman Build manages the full permit process, including drawings, engineering, and City submissions.
From initial consultation to occupancy, a second storey addition in Mimico typically takes 14–20 months: roughly 4–8 months for design, permits, and approvals, followed by 8–14 months of construction. We provide a realistic project schedule at the start so there are no surprises.
In most cases, yes. Mimico is undergoing rapid gentrification driven by lakefront proximity and strong demand for larger homes in Etobicoke. A well-executed second storey addition can double your living space and significantly increase resale value — often returning more than the construction cost in a neighbourhood where move-up buyers are actively competing for larger detached homes.
