    Home Additions & Extensions Services

    Home extensions allow you to build out your main floor by occupying a larger footprint on your property. Our house extension builders can add new rooms to your floorplan or extend existing rooms. You can bump-out your kitchen, extend your living room, or build an entirely new wing of your house.

    Home additions add a new level to your home, usually second story additions building upward. Our home addition contractors can add a new story to your home or expand your upper story if it is smaller than the supporting lower floor. Add new bedrooms, suites, or activity spaces with a view. Additions may also be considered the building of entire new rooms or suites compared to expansions, which may expand existing spaces.

    Add an entire new second floor to your home with a second floor additional project. With a skilled home additions company, your home can achieve new heights, potentially doubling your available square footage with a new floor of bedrooms, shared spaces, or loft designs. Consider everything you might do with an additional second story.

    A sunroom addition is a wonderful way to bask in warm sunbeams in elegant indoor comfort. Sunrooms are often built by extending a porch or patio with large picture windows so you can enjoy the comfort of an indoor environment and the glow of the sun. Often, these additions become solariums where both humans and plants absorb nourishing warmth and full-spectrum sunshine together.

    A dormer addition is when your new second story extends from the lines of the original roof, often with a smaller floorplan than the house below. Dormer additions can be quite stylish and typically improve the overall curb appeal and exterior design of the modified home. Home additions with dormer construction give you a chance to reimagine your home’s interior design and exterior style.

    Your home addition doesn’t have to be attached. If you are dreaming of the perfect private space for your home office, build an outdoor office in the garden. Backyard offices are extremely popular, allowing you to take full control of the size, style, and isolation from the rest of the house. By choosing the amount of glass, you can also enjoy an indoor-outdoor living design or watch the garden from your desk as you work.

    Your garage has infinite potential when it comes time for a home addition. Work with your custom home builder for a garage conversion, to expand the garage, or to add a second story addition above the garage. You can make room for more cars or build a garage workshop. You can add a guest suite, teen clubhouse, or home office above the garage. Or you can transform your entire garage and addition into a massive new living space for the whole family.

    A laneway house is also known as a backyard suite. It is a self-contained extra residence just for guests. In other words, your home extension contractors can build a luxuriously cozy guest house in your backyard. These separate little homes are typically connected to the back lane (why they are called laneway houses) and are perfect for hosting holiday guests or opening a private Airbnb.

    A garden house is an adorable little interior structure in your garden. It can double as a guest house, clubhouse, or home office without the requisite features of a laneway house. Your garden house can be anything you want it to be, from minimal to luxurious. Our house extension builders can craft your garden house to be versatile or dedicated to your own private purposes.

    When adding utility to your home, you can’t beat kitchen and bathroom additions. Many homes have tiny kitchens or not enough bathrooms – but improvement is within your power. Our expert house extension builders can not only make more room for your kitchen or add new space for bathrooms, we can also professionally re-plumb and wire the space for all the modern home features you’ve been dreaming of to make your custom home design complete.

    The beautiful thing about home additions and extensions is the ability to truly customise your home. Our custom home builders are proud to provide you with new space and personalised features to transform your current house into your dream home.

    Home Additions & Extensions FAQs

    The timeline will generally depend on the size and complexity of the addition, but generally a standard home extension would take an average of 8 to 12 weeks from breaking ground to completion.

    Large-scale projects that include second story additions or a multi-room expansion will take 3 to 6 months, depending on the necessities. This process will cover design, permits, foundation work, framing, and completing the finishing touches.

    We always provide a detailed timeline upfront, so you know exactly what to expect. Our expert team ensures your home addition is completed efficiently and to the highest standards.

    Yes, as a general rule, a building permit is issued before any sort of home addition or extension can begin. Again, the needs will vary from project to project, depending on the size and scope of your project. In general, the following are projects that usually need permits:

    • Room additions
    • Building a second story
    • Bump-outs
    • Extensions to your footprint (rear and side)
    • Major interior remodels that change the load-bearing walls
    • New plumbing, electrical, or HVAC systems as part of the addition

    Minor cosmetic updates may not require a permit, but it’s always best to confirm with your local municipality. For official guidance, check your local Ontario Building Permit requirements.

    Indeed! A professional home addition builder can construct and design freestanding buildings such as garages, guest houses, or in-law suites. These projects are in high demand to add property value as well as habitable space. Here’s what to expect:

    • Detached Garage Builds: Perfect for 1-car, 2-car, or even multi-vehicle storage with full electrical and workshop areas.

    • Guest House Additions: Constructed to order with bedrooms, bathrooms, and even mini-kitchens, perfect for rental income or in-laws.
    • Value Boost: Canadian data shows that well-planned accessory dwelling units (ADUs) can increase property value by 15% to 25% (source: CMHC: Additional Units in Homes).
    • Turnkey Service: Full design, permitting, and construction, from ground up to last finish.

    Yes, a well-planned home addition is one of the most effective methods of adding value to your home in the market. Whether you’re increasing living space or increasing usability, buyers will always be drawn to bigger, more usable houses. Here’s how different types of additions will typically add value:

    • Extra Bedrooms/Bathrooms: Can raise home value by 15% to 20% on average.
    • Additional Bedrooms/Bathrooms: Can add home value 15% to 20% on average.
    • Second-Story Additions: Usually increase value by 25% or more, depending on quality and location.
    • Finished Basements or In-Law Suites: Highly desirable for multi-generational living or rental income opportunity.
    • Rear and Side Extensions: Add living area and functionality of the entire house.

    Every marketplace is different, but spending money on a quality home extension generally pays off in the form of comfort and resale.

    There are many types of home additions available, each designed to add space, functionality, and value. Here’s a breakdown of popular options:

    • Room Additions
    • Second-Story Extensions
    • Sunrooms and Conservatories
    • Garage Conversions
    • Basement Finishing
    • Kitchen Extensions
    • In-Law Suites
