GS Construction builds home additions in Kingsville, Leamington, Essex and Harrow for families who love where they live and need more space: a larger kitchen and family room at the back, a main-floor bedroom, a sunroom, a second storey or a suite for a parent.
An addition is the largest project most homeowners ever take on. This page walks through the kinds of additions, how the build goes from the first visit to the day you use the new room, and what to think about before the first conversation.
Types of home additions
Whether you need a larger kitchen, an extra bedroom, a family room, or additional living space, we can help you expand your home to suit your changing needs. We work on rear and side additions, second-storey expansions, sunrooms, and in-law suites.
Every addition is planned around your home's existing structure, available space, and your vision, with the goal of creating a seamless extension that feels like part of the original home.
From the first visit to the new room
Every home addition begins with a visit to discuss your ideas, assess your property, and plan how the new space will connect to your existing home. We can also assist with the necessary building permits to help make the process easier.
A typical home addition takes approximately two months, depending on size and complexity. From foundations and framing to roofing, electrical, plumbing, insulation, and finishing details, we coordinate each stage with attention to quality and efficiency.
Foundation, framing and tying into the house
A successful home addition starts with a solid foundation and proper structural planning. We consider everything from footings and framing to roof connections, insulation, and integrating the new space with your home's existing systems.
Our goal is to create a smooth transition between old and new, with matching finishes, properly connected structures, and a finished space that feels like it has always belonged.
Outdoor builds: sunrooms, gazebos and backyard structures
Expanding your living space doesn't always mean adding another room to your house. We also build and install sunrooms, covered decks, pergolas, gazebos, sheds, and other backyard structures that make your property more functional and enjoyable.
Whether you're creating a relaxing outdoor retreat or adding practical storage, we can help bring your ideas to life with quality craftsmanship.
Questions to think about before the first visit
Before planning an addition, consider how you'll use the new space, who it will accommodate, and how it should connect to your existing home. Features such as separate entrances, bathrooms, storage, and accessibility can all influence the design.
Having a general budget and timeline in mind also helps us understand your priorities and plan a project that meets your needs.
Living at home during an addition
Many homeowners can continue living in their homes during construction. Whenever possible, we keep the new addition enclosed before opening it to the existing living space, helping minimize disruption to your daily routine.
We take pride in maintaining clean, organized work areas and treating your home with care. One of our clients, who had our crew working inside and outside their home for months, shared that everything was left clean and organized at the end of each day. It's the kind of attention to detail and respect for our customers' homes that we strive to bring to every project.

What homeowners say
“Gilberto was very knowledgeable about the permit process and worked alongside the Town to get everything done properly. He explained everything as he went along, including attending the Town permit visits. There were no surprises.”
“They worked for 6 months on our home, renovating the exterior (Deck, Porch, landscaping) and the entire interior (Bathrooms, kitchen, flooring, basement) and it was a great experience, everything was clean and organized before we left each day.”
“GS Construction is by far the best contracting company we've ever dealt with. Extremely punctual and professional. Not only did they get the renovation done on time, it was done within budget and done well.”

Home Additions questions
What kinds of additions do you build?
Rear and side additions, sunrooms and three-season rooms, second storeys and in-law suites, plus outdoor builds such as covered decks, pergolas and gazebos.
Is it worth building an addition instead of moving?
For many families it is, when they like the neighbourhood and the lot has room. An addition keeps you in the home and the neighbourhood you chose, with space designed for how you live.
How long does a home addition take?
A full addition takes about two months of construction on average, and longer for larger or two-storey additions. Planning and design come before that.
Can we stay in the house during the addition?
Many families do. The new space is built and closed in before the existing wall is opened, which keeps the disruption to a shorter window.
