Home Additions in Toronto & the GTA. Large-Scale Additions Built Right — With the Process to Match

A major home addition is one of the biggest projects a homeowner can take on — and one of the most rewarding. Whether you’re adding space for your family to grow, modernizing an older layout, or creating something entirely custom, the key to success is choosing the right team.

At Royal Home Improvements, we’ve been helping Toronto homeowners expand their space since 1969. We specialize in large-scale, full-service additions — managing everything from design and permits to construction and finishing. You’ll work with a proven team, follow a clear process, and always know what to expect.

The Royal Process: Built for Accuracy, Not Guesswork

We believe a successful home addition starts with a clear plan, honest communication, and the right team in place. Here’s how our process keeps your project grounded and stress-free — from the very first conversation to the final walkthrough.

1. Initial Consultation & Site Meeting

After you reach out, we’ll schedule a conversation to learn more about your goals, timeline, and expectations. This is your opportunity to ask questions, understand the process, and get a feel for how we work.

In many cases, we can provide a general ballpark based on similar projects. But rather than offering unrealistic quotes, we focus on accuracy — and that starts with proper planning.

If the scope, timeline, and approach sound like a good fit, we shift the discussion toward the next step: developing a detailed plans and permit package.

2. Design, Drawings & Permit Planning

This is where the project truly begins to take shape.

Our in-house team develops a comprehensive design package tailored to your home and vision. This includes:

Architectural, structural, and mechanical drawings
3D interior renderings
Cabinetry layouts and finish planning (if applicable)
All documentation required to obtain permits

3. Transparent, In-Person Pricing Proposal

Once your plans are finalized, we present a detailed construction proposal based entirely on the approved drawings and scope. We walk through the materials, timeline, and cost structure in person, ensuring total transparency and alignment before moving forward.

4. Construction & Dedicated Project Management

With permits approved and schedules set, construction begins — and this is where your dedicated project manager steps in.

Your project manager is more than just a scheduler. They’re your day-to-day advocate and leader on the ground — someone who knows your plans inside and out, coordinates every trade, keeps timelines tight, and solves problems before they reach your radar.

We keep you informed at every step through Buildertrend, a user-friendly digital dashboard where you can check progress photos, track milestones, and review updates in real time — whether you’re at work, on vacation, or across town.

You’ll also have a direct line to your project manager by phone, text, or email — and if you ever want to escalate something or just talk it through, you can always reach out to our leadership team directly.

5. Completion, Care & Warranty

Once construction is complete, we walk the space with you and ensure every detail is finished to the highest standard.

Your project is backed by a 5-year structural warranty, and our relationship doesn’t end at handoff — we’re available if questions arise down the road. With over 50 years of reputation in this city, we build with the long-term in mind.

When you choose Royal, you're not just getting a contractor — you're partnering with a company that’s stood behind its work since 1969.

No two homes — or homeowners — are alike, which is why every addition we build is tailored to the specific needs, lifestyle, and property of the client. Here are some of the most common types of additions we design and deliver.

Types of Additions We Build

We specialize in large-scale additions that expand your home’s functionality, improve flow, and increase long-term value — all while blending seamlessly with the existing structure. Every project is tailored to your goals and built with craftsmanship that stands the test of time.

Second-Storey Additions

Maximize your square footage without giving up your yard. Ideal for homeowners who love their location but need significantly more living space — from bedrooms and bathrooms to full upper-level layouts.

Garage Additions or Conversions

Add a new garage or repurpose your existing one into a fully finished space. Popular choices include home offices, gyms, or private guest accommodations.

In-Law Suites & Income Units

Design discreet, self-contained living spaces for extended family or future tenants. We build to code with the right infrastructure for privacy, safety, and flexibility.

Rear & Side Extensions

Create the space you’ve always needed — whether it’s a larger kitchen, a new dining area, or an open-concept family room. These additions can dramatically improve both livability and resale value.

Main Floor Primary Suites

Enjoy long-term comfort and accessibility with a spacious, private suite on the main level — ideal for aging-in-place or simply eliminating stairs from your daily routine.

Not sure what kind of addition makes the most sense for your home?

We’ll help you weigh the options and answer your questions — whether you’re ready to build or just exploring ideas. Let’s talk.

A major addition isn’t just about adding square footage — it’s about choosing the right team to manage every detail from start to finish. Here’s why so many Toronto homeowners continue to trust Royal Home Improvements with their most important projects.
