Home Additions Toronto

Full Service Design & Build

Sunnylea Homes is an award-winning full-service design-build firm creating thoughtful home additions across Toronto. Led by Geno and Marino Scopelleti with 35+ years of experience and HGTV-featured work, we combine smart design, careful planning, quality craftsmanship, and hands-on project management to expand older Toronto homes with new spaces that feel seamless, functional, and built to last.

A home addition can provide more room for a growing family, create a larger kitchen and living area, add a private primary suite, or make an older Toronto home better suited to your lifestyle.

Our team manages the entire project, including design, planning, permits, material selections, construction, licensed trades, and finishing work. Every addition is carefully designed to feel like a natural extension of the original home rather than a separate structure.

Our Home Addition Process

1. Design Consultation

We begin with a personal, in-home or office consultation to understand your home, goals, budget, and how much additional space you need. Geno, Marino, and the Sunnylea team review the existing layout and outline an addition plan that works with your home and lifestyle.

2. Planning, 3D Concepts & Selections

Our designers develop floor plans and 3D concepts, then guide you through layouts, materials, finishes, windows, flooring, cabinetry, and other selections. Every detail is planned so the new addition feels connected to the existing home.

3. Permits, Drawings & Approvals

Sunnylea Homes coordinates architectural drawings, engineering, zoning requirements, and building permits for your home addition, helping ensure the project meets Toronto and Ontario building requirements.

4. Scheduling, Ordering & Site Prep

We carefully schedule trades, order materials, coordinate structural work, and prepare the site before construction begins. Detailed planning helps reduce delays and keeps each stage of the addition moving efficiently.

5. Construction & Detailed Finishing

Our trusted trades complete the addition with careful workmanship, clear communication, and attention to detail. From framing and structural work to electrical, plumbing, flooring, millwork, and final finishes, we manage the project through completion.

After construction is complete, we inspect the addition and review the finished space with you.

Any remaining details are addressed before the project is closed and the addition is handed over for you to enjoy.

Frequently Asked Questions

How much does a home addition cost in Toronto?

The total cost of home additions in Toronto depends on the project scope, square footage, structural work, finishes, and existing structure. Home additions often start around $100,000, with costs ranging roughly from $200 to $1,000 per square foot. A second floor addition may average around $350 per square foot, so a 1,000-square-foot addition could cost around $350,000.

Sunnylea Homes can help Toronto homeowners create more living space with second story additions, rear additions, main floor extensions, garage additions, extra bedrooms, additional bathrooms, and family rooms. The right home extension depends on your existing house, lot, budget, and how you want to use the new space.

Yes. A second floor addition is a popular option when homeowners want significantly more square footage without expanding the existing footprint. A second story can add bedrooms, a master bedroom, a spa bathroom, or other living space while keeping the main floor available for kitchens and family areas.

A major home addition can take several months from design development through the final walkthrough. A typical project may take around 7 to 8 months, depending on architectural design, permits, structural engineering, site preparation, material availability, and the size of the addition. Sunnylea Homes manages the entire project from the initial consultation through construction.

Yes, most major home additions in Toronto require a building permit. Toronto also has rules for lot coverage, building height, setbacks, and other zoning requirements. Sunnylea Homes coordinates architectural drawings, structural engineering, building permits, and plumbing permits when required so the project follows the Ontario Building Code and local building codes.

Permits for home additions often take around 4 to 8 weeks, although timing can vary depending on the project and required approvals. More complex additions may also require zoning review, structural drawings, or revisions before the construction phase can begin.

A design-build company keeps architectural design, planning, project management, and construction under one roof. Sunnylea Homes works closely with homeowners throughout the entire process, which helps simplify communication between designers, engineers, trades, and the project manager.

Look for an experienced and reliable contractor with knowledge of Toronto homes, building codes, structural work, and home additions. Ask for recent client references, proof of insurance and WSIB coverage, and examples of past work. Professional contractors should also carry appropriate general liability insurance, commonly at least $2 million.

A detailed quote should explain the project scope, materials, labour, structural work, site preparation, permits, finishes, and any exclusions. Toronto homeowners should compare multiple independent quotes rather than choosing only the lowest price. The contractor should also explain how change orders and unexpected costs will be handled before work begins.

Sunnylea Homes is a full-service home additions company in Toronto with an experienced team managing design, drawings, permits, structural work, construction, and finishing. Whether you are planning a second floor addition, rear extension, garage addition, or main floor extension, our goal is to create a new space that integrates seamlessly with your existing home.
