Home Additions
Add real space for your family with carefully planned additions that feel seamless and keep budgets under control.
More Space for Your Family, With No Renovation Surprises
Your home may be in the right neighbourhood, but it no longer has the space your family needs. The main floor feels crowded, bedrooms are tight, and every visit from friends or relatives turns into a juggling act. Moving is one option—but so is a well‑planned home addition that gives you more living space without leaving the area you love.
The challenge is doing it without budget shocks, delays, or constant disruption to your family. Many home renovation projects start with rough estimates and vague plans, which is where the horror stories come from.
We design and build major home additions in Toronto—second‑storey, rear, and multi‑room expansions—using our Construction Playbook to lock in every decision, cost, and date before we build. You get the extra room you need, with a clear renovation process and no surprises from your contractor.
Is a Home Addition the Right Move for Your Family?
A home addition is a smart choice when moving doesn’t solve the real problem—staying in the neighbourhood you love while giving your family the space you actually need.
You might be considering an addition if:
- Your main floor feels cramped and crowded every time friends or family visit.
- Kids are sharing bedrooms and there’s no quiet space to work from home.
- You’d like room for aging parents or adult children, but there’s nowhere private for them to stay.
- You’ve looked at listings and realized you’d rather invest in your current home than start over somewhere else.
If that sounds familiar, adding well‑designed, permanent space can be the better long‑term decision—as long as it’s planned clearly and managed by a renovation contractor you trust. The right team will treat your addition as a serious home improvement, not just another small renovation project.
Home Additions We Focus On
We concentrate on major additions that transform how your home works day to day—not small patchwork projects.
Second-Storey Additions
Turn a bungalow or one‑and‑a‑half‑storey house into a full two‑storey home with proper bedrooms, bathrooms, and storage for a growing family. This kind of major renovation can be more practical than a full house renovation when you love your lot and want to build up instead of out.
Rear and Side Extensions
Expand your main floor to create a larger kitchen, family room, or dining area, with better flow to the backyard and more room to host. We think carefully about how the new construction ties into your existing layout and overall interior design, including future kitchen renovation or bathroom renovation plans if they’re on your mind.
Multi-Room Expansions
Plan and build several spaces together—kitchen, dining, mudroom, office, or playroom—so everything feels cohesive and finished to the same standard. You avoid a series of disjointed remodeling jobs and end up with one integrated home renovation project that actually fits how you live.
Space for Multi-Generational Living
Add dedicated space for parents, in‑laws, or adult children, with privacy and comfort built in from day one. A thoughtful home addition can be an important part of your long‑term home remodeling and family planning.
Every addition is designed around how your family actually lives—and engineered to tie in properly with your existing home so it feels seamless, not “tacked on.”
Why So Many Home Additions Go Wrong
Most “reno nightmare” stories start the same way: a big project kicks off before anyone has a clear plan, firm price, or realistic schedule.
Homeowners are often drawn in by a vague estimate that seems reasonable at first, only to watch the number climb as “unexpected” issues and extras appear once walls are opened. The new structure isn’t always properly tied into the existing house, which can lead to cracks, drafts, uneven floors, and future repair bills that far exceed the original renovation cost.
Permits and inspections move slowly, but no one explains what’s happening or why, so weeks pass with little visible progress. Decisions about layout and finishes get pushed to the last minute, and every late change adds time and cost. In the worst cases, a poorly managed construction project leaves families feeling like they have to chase their contractor just to get basic answers.
This is where working with the right home renovation contractors matters. A reliable contractor will give you a defined path, not just a quote.
Our approach is different. We use the Construction Playbook to plan your addition in detail before construction begins, so design, structure, finishes, price, and schedule are clear upfront. That’s how we keep budget deviation to less than one percent on our projects and avoid the surprises that make additions so stressful.
How Our Addition Playbook Works
A successful addition starts long before any demolition. Our Construction Playbook is a structured planning process that gives you a clear design, firm price, and realistic schedule before we build.
We begin with a discovery meeting and site review to understand how your family lives today, what isn’t working, and what kind of space you need. We look carefully at your home, the lot, and any practical constraints so the ideas we explore are realistic from the start. This is also where we may talk about other goals—such as future home renovation work, like a kitchen renovation, bathroom renovation, or interior renovations—so we can plan your renovation journey in a sensible order.
Next, we develop concepts and test feasibility. This is where options like a second‑storey addition versus a rear extension are compared, along with zoning, structure, and code requirements. You see what’s possible on your property before committing to a direction.
From there, we move into detailed design and selections. Room layouts, windows, finishes, flooring, and fixtures are all chosen with guidance, so you’re not making rushed decisions mid‑project. By the end of this stage, you know exactly what your addition will look and feel like, and how new materials and details will connect to the existing house.
Once the design is complete, we confirm a fixed price and schedule based on the full scope of work. Because everything has been thoroughly planned, our projects typically stay within one percent of the agreed price. You know what you’re getting, what it will cost, and how long it will take—so your total renovation budget is clear before you sign.
Only then do we move into construction. You work with one coordinated team—design, engineering, site management, and trades—supported by regular updates so you always know what’s happening and what’s coming next. There are no silent changes and no hidden line items, and you’re not left chasing multiple contractors or renovation companies to keep your addition on track.

Frequently Asked Questions
Do we need to move out during a home addition?
It depends on the size and location of the addition. For some projects, families can stay in the home with careful planning around access and safety. For larger or more intrusive work, we’ll walk you through what living on site would look like and when a temporary move might make more sense. Either way, we plan the sequence of work in the Playbook so you know what to expect long before construction starts.
How long does a typical home addition take?
Timelines vary based on the scale and complexity of the addition, as well as permits and inspections. During the Playbook phase, we build a realistic schedule around your specific design, not a generic estimate. You’ll see key milestones and an overall timeframe before you sign a construction contract, so you’re not guessing how long your home will be disrupted.
What happens if you uncover an issue once you open up the house?
Older homes can hide surprises, but we do everything we can to minimize them with a thorough site review, structural thinking, and an insurance‑grade approach to code and construction. If an issue does appear, we explain what it means, outline your options, and walk through costs before any decision is made. There are no silent changes and no hidden line items.
How do you handle permits and inspections in Toronto and the GTA?
We manage the permit and inspection process for you. That includes preparing drawings, coordinating with engineers where needed, submitting applications, and working with inspectors during construction. You don’t have to navigate city requirements on your own—we keep you updated on where things stand and what’s coming next.
Do you take on smaller projects, or just large additions?
Our focus is on major additions and full‑floor or whole‑home renovations where planning and coordination make the biggest difference. If your project is smaller in scope, we’re happy to speak with you and let you know honestly whether we’re the right fit.
