Second Story Additions Toronto

Second story additions are a great solution to add additional living space if your home does not meet property line considerations. By building up, you may actually have more space than building an extension. We have summarized what you need to consider when creating second story addition floor plans.

  • An addition that doesn’t require extra land: A second-story addition keeps your home’s footprint the same, giving you the extra living without losing part of your yard. Adding a second story also creates more square footage than your basic ground floor addition.
  • Significantly improve the home’s resale value: Second-story additions instantly upgrade your home’s resale value. Not only does it add square footage, but it creates additional functional space,  but it makes your home more appealing to potential buyers. 
  • Almost double the amount of living space: Adding a second story can almost double the amount of livable space in your home. If your family needs room to grow, adding more square footage to your current property will cost less than buying a new home in the long run.
  • Residents need to live elsewhere for months: Second-story home additions can take several months to complete. We suggest making different sleeping arrangements for your comfort and safety. Many families find a nice rental in the same neighbourhood to minimize disruption — especially if you have kids.
  • Consider aging-in-place and mobility issue: We ask clients to consider mobility and aging-in-place for second story additions floor plans. Think about adding open shower rooms, wide doorways and even a bedroom for a guest or caregiver. 
  • Local zoning: Second story additions may be restricted in some neighbourhoods. It’s essential to follow local by-laws and get the proper permits before starting construction.

Second story additions cost starts at $300 per square foot and there are a few different types for you to choose from:

  • Dormer: A dormer is a small room with a window that sticks up vertically from a sloped roof. These additions to attics and small second floors can provide more livable space and lots of natural light.
  • Partial second-story addition: The partial addition is a more cost-effective way to add square footage without committing to a full second story addition.
  • Full second story addition: This addition adds a second story that covers every inch of your original main floor. This will maximize your new livable space and your home’s resale value.

Room Addition Toronto

Room additions are the perfect way to get the extra living space you need. Adding a new bedroom or kitchen extension will increase the functionality of your home and its resale value. Here is some important information to think about when planning a room addition.

  • No second story required: By not building up, you are simplifying the construction process. You will get more square footage more quickly, without paying for basement underpinning or extensive electrical and plumbing work for a second floor.
  • Increase home value: Even something simple like a family room addition or mud room addition can add significant value to your home. Any additional square footage will be more appealing to potential buyers.
  • Added functionality: Room additions give you more space to live your life. A kitchen extension makes cooking and entertaining more enjoyable while a mud room extension helps keep your house cleaner and more organized.
  • Home access: Depending on the location and type of room addition, homeowners may not be able to access that certain area during construction.
  • Mobility planning: Are you planning to age-in-place with your current home? Any room addition design should consider accessibility and functionality for an elderly homeowner.
  • Property lines: Some local by-laws may restrict how close a home addition can come to your property line. The laws must be looked at and permits must be picked up before construction starts.

The cost of single room additions are also calculated with a price per square foot, starting at about $300 per square and going up depending on the scope of project and the type of materials required.

  • Sunroom addition: This addition allows you to enjoy the great outdoors all year long from the comfort of your home. It creates more room for living that increases resale value.
  • Kitchen extension: A kitchen extension makes room for a dining area, breakfast nook, or expanded countertops. Any kitchen renovation, especially kitchen additions, are guaranteed to add value to your home.
  • Mudroom addition: Finally, you can have a place to store everyone’s coats, hats, shoes, and boots. A mudroom addition can make a home feel less cluttered and help keep it cleaner for longer.
  • Family room additions: Are an excellent way to extend the functionality of your home while giving it more space. Whether you need a spot for games or just want extra storage, adding onto one side can give what’s needed without taking up too much valuable living space in other areas!

Garage Addition Toronto

Garage additions are a cost-effective and simple way to get more usable space in your home. You can build a man-cave, a mother-in-law suite or create a rental property. A garage addition can mean minimal disruption to your family at a reasonable price. We’ve collected the most important points to consider about garage additions.

  • Simple addition: A garage is a simple structure that’s quick and easy to build. There is no plumbing and HVAC installation required.
  • Increase value: Adding a garage can do wonders for your home’s resale price. Even if you’re just creating a new space for vehicle parking, securing storage or a dream workshop, you’re adding a functional area and value to your home.
  • Cost-effective: Without the need for plumbing, HVAC, insulation and fine decorative finishes, a garage ends up costing a lot less than other home addition options.
  • Size matters: The size of your garage addition depends on how many vehicles or how much you want to store inside. Then, consider whether your desired garage size and orientation to the road will work.
  • Attached or detached: Attached garages are less expensive to build and very convenient; you can go right from your warm home into your car during the winter. Detached garages are more expensive to build, but provide more security by being isolated from your home
  • Zoning laws: Some neighbourhood by-laws may restrict detached or attached garage additions. We do the zoning research and get the permits for you.

The cost of an attached garage can start anywhere between $55 and $65 per square foot, while a detached garage can cost more, starting between $65 and $75 per square foot.

  • Attached: Attached garages are connected to your home’s original structure, requiring minor renovations for an entryway. They are less expensive garage additions because there is less to build and existing utilities to connect with.
  • Detached: Detached garage additions are separate buildings with their own foundation that allows much more flexibility with design and placement. They are more expensive to build because they require more building materials.

Required Documents for Your Future Home Addition

Ensuring you have all the necessary documents in order is crucial to avoid complications down the road. At Lumara Homes, we understand the complexities of this process. Our expert team will not only help you identify the required documents but also assist in obtaining them, making your home addition project a seamless and stress-free experience.

Every home addition needs a permit for construction to begin and every permit begins with an application and architectural drawings sent to the city for review. Our designer drafts plans and ensures that the proposed addition meets local by-laws and regulations.

A separate permit is required if you’re making changes to your HVAC system. Because a home addition adds more square footage, you’ll need more radiators and ductwork. We provide certified drawings in your permit application, including heat loss prediction.

When it comes to moving old or existing plumbing or adding new pipes to your home, you may need to obtain the required plumbing and drain permits. Our dedicated team will take care of the paperwork on your behalf, ensuring a hassle-free and efficient process.

Before the demolition phase of your home addition begins, an environmental report is required to find possible toxic and hidden building materials such as asbestos. If harmful substances are found, they may have to be professionally removed before construction can begin.
