To put it simply, a home Extension or home addition is expanding the square footage of your home by building upward, outward, or toward the back of the property.

  • Insufficient space
  • Increase outdoor space and enjoyment
  • Increase the property’s worth

Tross Construction will tell you about these important aspects below so you can plan your project mindfully and easily.

Now you might be thinking, why do you require a home Extension?

In the first place, you should consider for yourself why you would like a home Extension. What is your goal?

A home Extension can provide many benefits to your family. Are you considering opening a home business and requiring an office? Do you require an additional living area? Perhaps, you have a backyard area you want to enjoy with a sunroom or covered patio?

Whatever your goal is, be sure to define your goal and choose a design that suits that goal. You don’t want to invest money in a project that will not be worth your time and money.

Whatever your objective is, be sure to determine your goal and choose a design that aligns with your goal. You don’t want to put money in a project that will not be equivalent to your time and money.

Before beginning a home Extension, you are required to consider some important factors in planning the project. Check restrictions and zoning regulations in your area.

In Ottawa, a home addition of around 10 square meters requires a building permit.

It is advised to collaborate with a contractor to define your:

  • Architectural style
  • Size of your Extension
  • Complexity of the project
  • The estimated cost of your home addition

Looking for inspiration? There are countless home Extension ideas to explore—from second-story additions to garage conversions and backyard suites. The right one depends on your lifestyle, budget, and long-term plans.

Home Extension Ideas To Choose From

A home Extension provides different options depending on your space, budget, and objectives. Expanding your home can improve functionality and property value.

Lateral Home Extension

Lateral Extensions increase your home size by increasing it sideways. This option is generally used to add garages, time and again with bedrooms and bathrooms above. It’s generally suitable for bungalows and cottages. However, it requires more land space.

Floor Addition

Adding a second story provides significant new living space, generally matching the square footage of the ground floor. It’s a big construction project and may need structural certification to make certain the foundation can support the new load. A staircase will be added, often causing homeowners to renovate the ground floor altogether. Roof removal may also need temporary relocation.

Rear Addition

Rear additions extend your home into the backyard and align with many home types, such as bungalows and cottages. There are two types:

Additions on Piles: No excavation required. Perfect for sunrooms or family rooms, though less insulated unless heated floors are added.

Additions on Concrete Foundation: More pricier, but enable Extension of both main and basement floors.

Important Considerations

Some municipalities restrict second-floor additions, making rear Extension a more preferred choice. Always think about your home’s current worth and possible ROI. Check local building permit needs in cities like:

  • Toronto
  • Ottawa
  • Sudbury
  • Richmond Hill
  • Markham

Professional Guidance

Begin your project by consulting architects, engineers, and contractors to establish a safe and valuable Extension.
