Design Build Additions

Without the assistance of an experienced, competent, professional, and trustworthy contractor, the process of designing and building an addition can be intimidating. Since 1995, we've been successfully planning and building superior extensions for our customers in the GTA and neighboring areas. At Irex, we provide complete turn-key design and construction services. When you deal with Irex, you'll have designers, draftsmen, engineers, project managers, and trades all working together as a team to ensure you get a final product that you and your family will be proud of for years to come. We will collaborate with you to develop a project plan that meets your requirements.

It is important that designers and project managers work together to ensure that what is on paper is within your budget. The key to a successful design is a thorough understanding of how the homeowner intends to use the space. We'll strive to grasp how the space will be used after we've taken the time to understand why you're adding square footage to your current home, and then make recommendations on how to maximise the functioning of your newly planned home.
