House Additions | Toronto, Mississauga, Caledon, GTA

You love where you live, but your house is just too small.

Perhaps your home needs an extra bedroom, or a larger kitchen, or additional living space. Sometimes it's the need for a home office, a studio, a garage or a workshop. Whatever your additional space requirements, it may be time to consider building an addition to your home.

A house addition project requires careful planning and preparation. The house addition must not only meet the space requirements, but it must also integrate seamlessly with the existing house, both aesthetically and structurally. Items such as mechanical connections and services must be considered. Is the existing furnace sufficient to heat the larger space? How will the new duct work and plumbing be connected to the existing? Our goal is to have your house addition flow seamlessly from the existing home into the new space.

There are many types of home additions, and ways of adding a house addition or extension to your home:

  • Rear house addition / Back of the home addition
  • Side house addition
  • Front home addition
  • Second storey home addition/Second floor house addition
  • Room above garage
  • Split-level home addition
  • In-law suite home addition / accessory apartment

Second Storey Home Addition

Adding a second storey addition to a house, sometimes referred to as a second floor addition or a bungalow top up, is a great choice for bungalows and single storey homes, and when the existing property is too small for a house addition at the back or at the side of the home.

Second storey additions are also a popular choice for homeowners who enjoy their backyards and do not want to lose the backyard space.

A 2nd storey addition is usually built on top of a single storey home or a bungalow, although sometimes it may be also built on a split level house, or by adding a room above a garage.

Adding a second storey addition to your home usually includes extensive renovations to the main floor - especially in the case of a bungalow. Bedrooms are moved to the new 2nd floor, and the existing main floor bedrooms are often removed to make space for a larger main floor kitchen, living room and dining room, and sometimes a home office.

Rear House Addition

An addition to the back of the house is a popular choice where the existing house is already a two storey home, or in the case of smaller house additions where perhaps only one room is being added. Sometimes the desire for main floor living, and the avoidance of staircases is the reason space is added to the main level at the back of a bungalow.

Adding a room to the house, such as an additional bedroom, a new family room, or a larger kitchen are the some of the primary uses of back of house additions. An addition to the back of the house reduces backyard space, therefore homeowners should carefully consider what is important to them before choosing whether to build up, or to the back.

Front House Addition

Many older homes have small front entry spaces.  Limited space for multiple people, shoes, backpacks and closet space.

Adding a small addition or extention to the front of the house can improve the functionality of the home, as well as improve the appearance. Adding space to your house at the front entrance can make the home more livable.

We have designed and built many front home additions over the years, some of which are features in your house addition project gallery.

Third Floor Home Addition

Most older homes in the central areas of Toronto are already two storey homes, and are built on properties that are too small to allow an addition at the back of the home.

When the home is already two storeys, and there's no room to build to the back, a 3rd floor home addition may be an option to create additional space.

Third storey home additions are more complex than most house addition projects.

Secondary Suite Additions

Many homeowners are looking to adding space to their home to have extended family living with them.  It may be their aging parents, or sometimes it's their children.  But they want to create a separate space for them.

Most municipalities in the Greater Toronto Area allow the creation of a second dwelling unit within an existing home, or the expansion of the home to create a dwelling unit.

We have built house additions with as separate dwelling units with full services, including kitchen, bathroom, laundry and separate entry.
