Major Renovations & Additions
Plan major additions, full‑level renovations, or secondary suites with one clear process that keeps design, pricing, and timelines predictable.
Major Renovations and Additions Without the Reno Nightmare
If you live in an older Toronto home, there’s a good chance the way it works day to day no longer fits your life. Maybe the main floor is a maze of small rooms, the upstairs doesn’t serve your family, the basement is underused, or you simply don’t have enough space for the people who now call your house home.
At that point, small, one‑room home improvements aren’t enough. You need a major change—a full home renovation, home addition, or complete renovation of key floors—and you want to avoid the renovation horror stories that come with big projects started on vague plans and rough estimates.
We specialize in major renovations and additions for Toronto homeowners who want to re‑think their home, not just patch it. Using our Construction Playbook, we plan and price every detail before construction begins, so design, renovation budget, and schedule are clear from day one.
What We Mean by “Major Renovations & Additions”
When we say “major,” we’re talking about house renovation work that significantly changes how your home functions—not quick cosmetic updates.
That includes:
- Reworking an entire main floor or second level as part of a full house renovation or interior remodel.
- Adding a new floor or a substantial rear or side extension as a home addition or home extension.
- Creating a legal, self‑contained secondary suite or accessory unit as part of a broader home renovation project.
These renovation projects affect structure, layout, and daily life. They involve multiple trades, important design and interior design decisions, and a serious investment. If you’re looking for a single bathroom renovation, minor condo renovation, or small repair, we may not be the right fit. If you’re ready to rethink how your home supports your family, you are in the right place.
Three Ways We Transform Existing Homes
Every major project is different, but most fall into one of three paths. Each has its own dedicated page with more detail.
Home
Additions
For families who love their neighbourhood but have simply run out of room.
We plan and build major additions—second‑storey, rear, and multi‑room expansions—so your home gains the space you need without feeling like something was just bolted on. The goal is a seamless result that looks and lives as if it was always meant to be there. Along the way, we consider how new space connects to your existing kitchen, living room, basement, and other key living areas, so the entire renovation feels cohesive and supports your everyday living space.
Full‑Level & Whole‑Home Renovations
For homes where the layout no longer works, no matter how you arrange the furniture.
We replan and rebuild entire floors or whole interiors, turning dated, choppy spaces into cohesive, modern homes. This can include major kitchen renovation work, updated bathroom renovations, basement renovation or basement development, and new interior design details that tie everything together. Instead of taking on years of small, disruptive projects, you get one well‑planned transformation with a clear design, budget, and schedule.
ADUs & Secondary
Suites
For families planning multi‑generational living or looking to create a safe, legal rental suite.
We design and build code‑compliant ADUs and secondary suites—in basements, over garages, or within the existing footprint—so you can support the people you care about or add rental income without taking on compliance or safety risks. These projects often tie into broader basement renovation or interior renovation plans as part of a complete renovation strategy for your Toronto home.
Why Big Projects Go Wrong
Most major home renovation and home addition horror stories start the same way: work begins before there’s a complete plan.
Scope is only loosely defined. Costs are based on rough numbers, not detailed designs. Layouts, structural changes, and finishes get decided as the project unfolds. Separate trades and renovators come and go, but no one is fully accountable for the whole picture. Timelines slip, budgets drift, and homeowners feel they have to micromanage just to keep things on track.
That’s not how we work.
For projects of this size, guesswork is not acceptable. We use the Construction Playbook to plan your renovation in detail before construction starts, so you know:
- What is changing and why
- What it will cost, with pricing that typically stays within one percent of the agreed amount
- How long it will take, with a realistic schedule built around your specific design
You get one coordinated team - design, planning, and construction - working from one clear plan, instead of juggling multiple renovation contractors and general contractors.
How the Construction Playbook Supports Every Major Reno & Addition
Whether you end up adding space, reworking a full floor, or building a secondary suite, every major project with The Built Group starts the same way.
Discovery & Walkthrough
We walk your home, listen to what isn’t working, and understand what you want your life in the house to look like. This is where we start to explore whether an addition, a full‑level renovation, a basement renovation, or a secondary suite—or a combination of them—might make sense. At this stage, we also talk about your goals for kitchen renovations, bathroom renovations, or future basement finishing if they’re part of your long‑term renovation journey.
Concept & Feasibility
We test ideas against real‑world constraints: structure, zoning, and code. You see options for how your home could change, and what each path involves, before committing to a direction. If building permits are required, we plan for them early in the renovation process so there are no surprises later.
Detailed Design & Selections
Room layouts, finishes, and fixtures are planned in advance. That can include kitchen layouts, bathroom renovation details, basement development, interior design selections, and more. The aim is to reduce decision fatigue and avoid rushed choices partway through construction.
Fixed Pricing & Schedule
Once the design and scope are complete, we confirm a clear contract. Because everything has been thought through, our projects typically stay within one percent of the agreed price. You see the numbers and the timeline before you sign, so your renovation cost and total budget are clear.
Construction & Weekly Updates
Construction begins only after the Playbook is complete. You work with one accountable team that keeps you informed with regular updates, so you always know what is happening and what comes next. You’re not left chasing a contractor or trying to manage multiple renovation services by yourself.
Every major renovation and addition we take on follows this same structure. The details change; the process does not.
Proof That the Process Works
Families who choose us for major renovations and additions tell us they value two things: the way their home feels when it’s finished, and how steady and predictable the experience felt along the way.
They often come to us wary of blown budgets and drawn‑out timelines. After going through the Playbook, they have a clear plan, firm numbers, and a realistic schedule. When the work is done, they tell us the final cost matched what was agreed and that there were no unpleasant surprises along the way.
Our average pricing deviation across projects is less than one percent. That’s how we keep our word and protect your investment—and why so many Toronto homeowners trust us as their renovation company for larger projects instead of piecemeal work.
Not Sure Which Path Is Right for Your Home?
You might know that your house needs a major change, but not whether that means an addition, a full‑level renovation, a whole‑home transformation, or a secondary suite. That’s normal. Sorting that out is part of our job as your experienced renovation contractor.
