Second Storey Addition · Toronto, Ontario

Second Storey Addition Lawrence Park

Lawrence Park's generous lots are lined with 1920s–1940s Arts and Crafts and Tudor Revival homes — architecturally rich, but often short on upper-floor space. Kopman Build adds full second storeys that double your living area while respecting the craftsmanship and character the neighbourhood is known for.

Why Lawrence Park clients choose Kopman Build

Lawrence Park is one of Toronto's most architecturally cohesive neighbourhoods, and a second storey addition here demands more than structural competence — it demands design sensitivity. The existing Arts and Crafts and Tudor Revival homes carry original brickwork, timber detailing, and rooflines that must be matched or thoughtfully extended, not overwritten.

Some Lawrence Park properties carry heritage designation or sit within areas subject to heritage review, which adds a layer of City approvals before a building permit is issued. Kopman Build works with heritage-experienced architects and navigates that process as a standard part of our scope — not an afterthought.

Dustin Kopman founded the company in 1999 after growing up in construction through his family's firm, G&G Enterprise. Every Lawrence Park project is managed by someone who understands the craft behind these older homes and what it takes to add to them properly.

What we build in Lawrence Park

Full Second Storey

A complete upper floor added to a Lawrence Park bungalow or one-and-a-half storey home — master suite, bedrooms, and bathrooms integrated with the existing structure.

Heritage-Sensitive Design

Matching original brickwork, roofline profiles, and Arts and Crafts or Tudor Revival trim details so the addition reads as part of the original home.

Custom Kitchen Renovations

Many Lawrence Park second storey projects trigger a full kitchen renovation below — we handle both scopes under a single contract and single site team.

Custom Bathroom Work

New primary ensuites and family bathrooms on the upper floor, finished to the level Lawrence Park homes command.

Basement In-Law Suites

Basement finishing for in-law suites as part of a whole-home renovation — a natural companion project when the main structure is already open.

Full management of City of Toronto building permits, heritage review submissions, and Committee of Adjustment applications where required.

Questions about second storey additions in Lawrence Park

How much does a second storey addition cost in Lawrence Park?

A second storey addition in Lawrence Park typically runs $350,000–$650,000+, depending on the footprint, finish level, and the structural condition of the existing 1920s–1940s home. Heritage-sensitive detailing — matching Tudor Revival brickwork or Arts and Crafts trim profiles — adds cost but is essential to maintaining the neighbourhood's character and resale value. Kopman Build provides a detailed line-item estimate before any commitment.

Do Lawrence Park homes have heritage restrictions that affect a second storey addition?

Some properties in Lawrence Park carry heritage designation or fall within a Heritage Conservation District, which requires design review and approval from the City of Toronto's Heritage Planning staff before a building permit is issued. Even non-designated homes in the neighbourhood benefit from design that respects the prevailing Arts and Crafts and Tudor Revival character. Kopman Build works with heritage-experienced architects and manages all City approvals.

How long does a second storey addition take in Lawrence Park?

From initial consultation to occupancy, a second storey addition on a Lawrence Park home typically takes 14–20 months. This includes 3–6 months for design and heritage review (if applicable), 4–8 months for permitting, and 7–10 months of construction. We provide a realistic full-project timeline at the outset so there are no surprises.

Can you add a second storey while we stay in the house?

Living in a Lawrence Park home during a second storey addition is challenging — the roof is removed and the upper structure is open to weather for a period. Most clients choose to vacate for the structural and weather-tight phases (typically 8–14 weeks), then return once the new storey is enclosed. Kopman Build will walk you through the sequencing and help you plan around it.
