## What Is a Home Addition?

A home addition expands your house — building up with a second storey, topping up a bungalow, or extending out the rear — so you gain the space your family needs without leaving the neighbourhood you love. For many Toronto homeowners, an addition is the smarter alternative to selling: you keep your street, your schools, and your community, and you end up with a home built around how you actually live.

Additions are the most complex projects we take on. They involve structural engineering, foundation work, roof framing, and a permitting process that often includes the Committee of Adjustment. As a

, we manage all of it under one roof — architectural drawings, engineering, permits, and construction — with a single point of contact from feasibility to final inspection.

Because an addition is a major build, our fixed-price model matters here most of all. We do not lock the price on a guess. We complete the architectural drawings and structural engineering first, scope every element, and then confirm one guaranteed price. A project of this size should never become a financial gamble.

### What’s Included

Our additions cover the full scope: zoning feasibility, architectural drawings, structural engineering, building permits, Committee of Adjustment applications, foundation extensions, framing, roofing, exterior finishes, interior build-out, and final clean-up.

## Common Addition Problems We Solve

### You Have Outgrown Your Home but Love Your Street

Moving means giving up your neighbourhood, your schools, and your community. An addition keeps all of that and gives you the extra bedrooms, larger primary suite, or family space you need.

### Permits and Zoning Feel Overwhelming

The Committee of Adjustment, minor variances, lot coverage limits — the approval process stops many homeowners before they start. We handle every application and hearing, so the bureaucracy is our job, not yours.

### Fear of an Open-Ended Budget

Additions have a reputation for spiralling costs once construction uncovers surprises. We complete engineering before pricing, build proper contingency into the scope, and lock the figure, so a six-figure project stays predictable.

### Matching New Construction to the Existing Home

A poorly executed addition looks bolted on. Our design team ensures the new structure integrates with the existing rooflines, finishes, and proportions so the result reads as one cohesive home.

## Planning Your Home Addition

Every addition begins with a feasibility review: we check zoning, lot coverage, and setbacks to confirm what is possible on your property. From there we move into architectural design and 3D renderings, then structural engineering and permits. Only once that planning is complete do we lock in the fixed price and reserve your crew — so the most ambitious project in your home’s history starts on solid ground.

Transparent Pricing

## How Much Does Home Additions Cost?

Home Additions projects with our team start from the figure below. The exact number depends on scope and finishes. Once pre-construction planning is complete, that figure becomes a firm fixed price with zero allowances.

## Additions Renovation FAQs

How much does a home addition cost in Toronto? expand\_more

Home additions are the largest projects we take on, and most start around $175,000 and rise with size, structural complexity, and finish level. A second-storey addition or bungalow top-up costs more than a modest rear extension because it involves significant structural and roofing work. We lock in the fixed price after architectural drawings and structural engineering are complete, so the budget for a major project is firm.

How long does a home addition take? expand\_more

Additions are multi-month projects. Design, engineering, and permits take time before construction begins, and the build itself runs several months. Because we book projects three to four months ahead and reserve a dedicated crew, the construction schedule stays predictable once it starts.

Do I need a permit for a home addition? expand\_more

Yes. Every addition requires a City of Toronto building permit, and many also need Committee of Adjustment approval for a minor variance — for example, when the addition affects setbacks or lot coverage. We manage the entire process: drawings, engineering, applications, and inspections.

What is the Committee of Adjustment, and will my project need it? expand\_more

The Committee of Adjustment reviews requests for minor variances from the zoning by-law. If your addition slightly exceeds height, setback, or lot coverage limits, it likely needs Committee approval. We assess this during the feasibility stage and handle the application and hearing for you.

Can you add a second storey to my bungalow? expand\_more

Yes — bungalow top-ups are one of our most requested additions. We assess the existing foundation, design the new storey, manage the structural engineering and permits, and build the full second floor, all on a fixed price confirmed after engineering.

Can we stay in our home during an addition? expand\_more

It depends on scope. Some rear extensions allow you to stay with the work area sealed off, but second-storey additions and bungalow top-ups usually require temporary accommodation because the roof is opened. We plan living arrangements with you during pre-construction so there are no surprises.

What is included in the fixed price for an addition? expand\_more

The fixed price covers architectural design, structural engineering, permits and variance applications, foundation work, framing, roofing, exterior finishes, interior build-out, and final clean-up. Everything is scoped before the contract is signed.

Do you offer a warranty on home additions? expand\_more

Yes. As a licensed and insured general contractor, we stand behind our structural and finishing work and pledge a strict two-business-day response time on all warranty claims.
