Second Floor Additions in Leaside

A second floor addition in Leaside is not like building one in most other Toronto neighbourhoods. The design expectations are higher, the permit process often involves the Committee of Adjustment, and the finished product has to earn its place on a Leaside street. GYRM builds these properly.

Why Leaside Families Stay?
The schools, the streets, and the shortage of bedrooms

Northlea. Bessborough. Leaside High. The Bayview corridor. The quiet residential streets with mature trees. Leaside has a short list of things that are genuinely difficult to replicate, and families who live here rarely want to leave.
The homes are the constraint. Leaside's older bungalows and smaller two-storeys were not built for three-child families with two home offices and the expectation of a primary suite. A second floor addition is the standard solution — and in Leaside, it is a significant investment that has to be done to the standard the neighbourhood demands.

GYRM has completed second floor additions and home addition projects in Leaside. We understand what the Committee of Adjustment expects here, what architects the neighbourhood's design standards require, and what construction quality Leaside buyers and their neighbours will scrutinise.

What You Get

Second Floor Additions in Leaside

What a Leaside second floor addition adds

A typical Leaside second floor addition adds 800 to 1,200 square feet to an existing bungalow or one-and-a-half storey home. Most projects deliver a proper primary suite with ensuite, two additional bedrooms, and a laundry room on the upper floor — leaving the entire main floor for living.


The design has to be proportional to the existing home and respectful of the streetscape. Massing, roofline pitch, window proportions, and exterior materials are all assessed during the design phase with a view to what will be approved at the Committee of Adjustment and what will hold up to neighbourhood scrutiny over the long term.

The Committee of Adjustment Reality

Why most Leaside additions go to the Committee of Adjustment

Many Leaside lots were created under older subdivision plans that predate the current Toronto Zoning Bylaw. Current setback, height, and floor-space-index requirements frequently differ from what the original lots were built to. A second floor addition on a standard Leaside bungalow often triggers a minor variance application because the proposed addition exceeds current permitted height or FSI on that specific parcel.


This is not unusual. It is not a barrier. But it adds 3 to 5 months to the pre-construction timeline and requires properly prepared drawings and a clear rationale for why the variance is appropriate for the site and neighbourhood.
GYRM identifies whether a variance is required at the initial consultation. We build the Committee of Adjustment timeline into your project schedule from day one. We have never submitted a Leaside application to the CoA and been surprised by the outcome.
