Services We Offer

Second-Storey Additions
A second-storey addition allows you to double your living space; add bedrooms, bathrooms, offices etc.; and improve your home’s curb appeal. We can either remove your existing roof and build a new second storey from scratch or temporarily lift your roof and add a new level underneath, ensuring your second-storey addition seamlessly blends with your existing home and style.

Rear Extensions
Rear extensions are a common and practical home addition. They allow you to extend your living space to the back of your house, creating more room for your kitchen, dining area, family room, or any other space, and enhance views, natural light and indoor/outdoor connections. We can either extend your existing floor plan to create a new space or create a fresh first-floor layout.

Kitchen & Bathroom Expansions
Enhance the functionality and comfort of your home by enlarging your existing kitchen or bathroom. These expansions also offer a chance to make your home not just tailored to your needs, but also more energy efficient. Our design and construction experts will guide you through the process to create the dream kitchen or bathroom that meets your needs.

Sunrooms & Enclosed Porches
A great way to add more natural light and warmth to your home! Sunrooms and enclosed porches allow you to enjoy the outdoors without exposure to the elements or insects and can serve various functions, such as a dining area, lounge, hobby room, mud room, or greenhouse. We’ll design and build an enclosure that is well-insulated, ventilated, heated, esthetically pleasing, and durable.

Step 1 - Consultation

Step 1 - Consultation

This first meeting is crucial to lay the foundation of a successful home addition and to establish a strong working relationship. We determine if we are the right fit for each other and our team visits your home to assess its current condition. We then discuss your vision, objectives, expectations, and budget for your home addition renovation. Based on these discussions and our expertise, we provide you with a preliminary cost estimate.

Step 2 - Design

Step 2 - Design

In this phase we match you with an in-house designer, project manager and estimator who prepares a detailed scope of work and drawings for your dream project. We conduct a comprehensive house inspection to pre-emptively identify potential obstacles, ensuring a smooth construction process. We pride ourselves on maintaining close collaboration with you throughout the design phase and promise to deliver you a perfect balance between design and budget.

Step 3 - Quote

Once the design is finalized, we prepare a renovation agreement that includes a fixed-price quote, a comprehensive and detailed scope of work, and payment and construction schedules. Our team is committed to providing unparalleled quality and value, and collaborating with you to ensure the project remains aligned with your budget. The quote we offer encompasses all project specifics and will not increase throughout the renovation process. That is our promise to you.

Step 4 - Construction

Step 4 - Construction

Your dedicated project manager oversees the entire project, and an on-site supervisor ensures construction advances smoothly and on schedule. We prioritize limiting disruption to your daily life and maintaining a clean, safe working environment.

Then all that’s left is to enjoy your new space!

Questions Our Customers Often Ask About Home Additions

What is the cost of a home addition in Toronto?

Typically, they start at about $100,000. The cost may vary from $200 to $1,000 per sq. ft. and will depend on various factors, such as the type, size, design, and complexity of the home addition. Other factors such as the materials used, or if electrical, plumbing or HVAC work is required will also impact the price. Often, an addition requires replacement of an existing furnace. For a more accurate estimate for your home addition, contact our team directly.

The average project will take 8 to 15 months, including design and pre-construction planning. The duration of a home addition project depends on various factors, such as the scope and scale of the home addition, the design and planning process, the permit process, the weather and site conditions.

Home addition projects are complex and challenging and may encounter some issues or difficulties, including:

  • Appreciating the cost; often it is more than people are expecting
  • Finding a reliable and reputable contractor with a team of experts who can deliver quality work and service on schedule
  • Obtaining the necessary permits and approvals from the municipality and other agencies
  • Coordinating with neighbours who could be impacted by the project
  • Minimizing renovation disruptions and inconveniences to the homeowners and their home

As a one-stop shop, SOSNA will handle the entire project and eliminate these concerns. When you choose us, you are choosing a caring, reputable renovation company with an experienced team and proven process to ensure your home addition project is as stress-free as possible.

The Municipal Property Assessment Corporation (MPAC) assesses the value of your property, which determines how much property taxes you pay. MPAC considers various factors when assessing a property’s value, such as the location, size, age, condition, and features of your property, and the sales of comparable properties in your area. A home addition may increase your property value and, consequently, your property taxes. However, the increase depends on the type and extent of the home addition, as well as the tax rate of your municipality. You can contact MPAC or your local tax office to get an estimate of how much your property taxes may increase after a home addition.

Quote

Estimating renovation projects inherently involves some guesswork, but we take steps to minimize it as much as possible. Here’s how:

Crystal-clear Design Drawings: Our meticulous drawings go beyond basic sketches and floor plans. They include precise measurements, elevations, sections, and details with specifications for materials and finishes and clear layouts for plumbing, electrical, and mechanical systems. This level of detail allows us to calculate material quantities and labor hours more accurately.

Upfront Material & Fixture Selection: We work with you to select all materials and fixtures – tiles, flooring, cabinets, countertops, accessories down to the door knobs on your cabinetry – before finalizing the quote. This eliminates the need to estimate costs based on allowances, reducing the potential for surprises later.

Thorough Inspections: Before finalizing the quote, we thoroughly inspect your home’s structure, plumbing and HVAC systems, and electrical wiring. This uncovers potential unseen issues that could impact the project scope, cost, and design. By identifying these issues upfront, we can factor them into the quote, avoiding unexpected cost overruns during construction.

Only after we complete all the above-mentioned steps do we provide a fixed-price quote that we guarantee will not change during construction.
