How to plan a home addition
When planning your home addition, start with a direction: up, down, or to the side? The direction you choose to extend is only one of many major factors involved in expanding your home. Find a home addition contractor to oversee the process with expert knowledge and skill.
How much does it cost to build an extension to your house?
Home addition projects can cost as little as a DIY greenhouse kit and some weekend elbow grease, or as much as the price of your current home. Your location, the size of your house extension, and the structural changes involved will all contribute to your house extension costs. In most parts of Canada, the price per square foot varies between $100 and $200. Building on existing foundations is a good way to bring the price per square foot down.
|Type of renovation||Predictable budget|
|Home extension on piles||$200 – $250 sq. ft.|
|Home extension on foundation/slab||$300 – $250 sq. ft.|
|Storey addition||$250 – $350 sq. ft.|
Demolition not included.
What’s typically included in a home addition?
To add an extension to your house, you’ll usually begin by working with an architect or structural engineer to draw up blueprints and apply for a building permit. Once the blueprints are finalized and the permit is obtained, take the time to consult with your home addition contractor to determine how and when the work will take place. Demolition of walls and supports may be required, as well as laying a new foundation or installing concrete pilings. After the general structure of the home extension is in place, the rooms will be framed and the plumbing, electrical, and HVAC work will be completed. Finally, the drywall, flooring, and any painting or finishing can be done.
