    TYPES OF HOME ADDITIONS

    Second Floor and Side Addition

    Adding a second storey is a great way to increase your living space without having to move or sacrifice your outdoor space. It also means that any permanent exterior features in your current home, such as patios, fences, sheds and driveways, can remain the same.

    Garage Addition

    A garage addition helps expand your existing garage on the property to add extra space for your cars, increase storage space, or even create a new living space. Garage additions are a great way to add a home office, guest suite, or rental home to your property and boost the resale value of your home.

    Dormer Addition

    A dormer is a cost-effective and straightforward home addition option. Unlike other home additions, a dormer does not interfere with the existing structure and only requires minimal wiring and water supply. If you’re in need of more space but have limited exterior space, a dormer is a great solution.

    Kitchen Addition

    Is your kitchen too cramped for you to cook comfortably or host guests? A kitchen addition will help increase much-needed floor and counter space, allowing you to redesign the kitchen layout to improve overall functionality.

    Basement Extension and Underpinning

    We lower and reinforce existing foundations through advanced underpinning techniques, creating full-height, functional basements with increased ceiling clearance, improved drainage, and long-term stability. From excavation and structural engineering to waterproofing and interior finishing, we manage every detail with precision.

     

    OUR BUILDING PROCESS

    Our mission is to set the highest standards for construction.

    Phase 1 : Consultation

    In this initial phase, we meet with the client to understand their needs, goals, and vision for the project. We assess the existing conditions, discuss feasibility, and outline the general scope, budget, and timeline expectations

    Phase 2: Design and Permits

    Our design team creates detailed plans based on client input and project requirements, including floor plans, elevations, and code compliance, and applicable permits with revisions made until final approval.

    Phase 3: Estimation

    Once the design is finalized, our project estimator will prepare the cost estimate. This includes materials, labor, and any other project-related expenses.

    Phase 4 : Construction

    With approvals and permits in place, construction begins. This phase includes demolition (if applicable), structural work, framing, mechanical systems, and interior/exterior finishes. Progress is monitored closely to ensure quality and adherence to the project plan.

    Phase 5 : Inspection

    This phase includes comprehensive inspections by our team and any relevant authorities to confirm that all work complies with building codes, safety regulations, and project specifications.

    During this stage, we also complete any necessary touch-ups, address outstanding items, and ensure that finishes and fixtures are polished and properly installed.

    Phase 6: Final Completion and Handover

    we meticulously review every aspect to ensure your satisfaction. The final handover process is seamlessly guided, marking the transition of your new custom home into your possession

    Home Extensions or Additions: Permits and Required Documents

     

     

    Building Permit
    A building permit is essential as it is formal permission to commence construction from the City of Toronto. Our engineers will review and stamp the architectural drawings for permit approval, which typically takes 15 to 20 days, depending on the size of the building.
    ‍
    HVAC Permit
    Adding extra space to your home means there will probably be adjustments to your current heating system. Whether it’s adding new radiators or upgrading the furnace system, our in-house mechanical engineers will provide stamp drawings of the HVAC plan with heat loss calculations for the city officials to review and issue a permit. 

    Plumbing and Drain Permit
    A plumbing and drain permit is needed if the home addition project involves repositioning plumbing fixtures. If your project involves adding a kitchen or a bathroom, this permit is likely a requirement. Our team will handle all necessary documentation to meet the local plumbing permit requirements before commencing work.

    Environmental Report
    Demolition is often the first step in the home addition process. Older home demolitions can often release dangerous materials, such as lead paint or asbestos, into the environment. If certain designated substances are found in lab tests, remediation may be required before demolition.

    Frequently asked questions

    The cost of your home addition will depend on the type and size of the project. On average, renovation costs between $90 and $200 per square foot. Our project supervisor will help you create a budget during the design development stage.

    The duration of a home addition varies depending on the size and complexity of the project, but most additions take anywhere from 3 to 6 months to complete. Smaller additions or straightforward layouts may be finished in a few months, while larger or more customized builds can take longer due to planning, permitting, and construction stages. Your contractor will provide a detailed timeline based on the specific scope of work.

    Whether you need to move out during a home addition depends on the scale and scope of the project. In many cases, homeowners can remain in the house if the work is limited to external areas or can be safely separated from the main living space. However, if the addition involves major structural changes, significant electrical or plumbing work, or disrupts essential areas like the kitchen or bathrooms, temporarily relocating may be necessary for safety and comfort. Your contractor will guide you based on the specific details of your project.
