Need quotes from home extension contractors?

In 2026, across Canada, a typical kitchen bump-out (or micro-extension) often falls between $30,000 and $70,000, depending on structural complexity and region. The cost per square foot generally ranges from $300 to $700, which is higher than for larger extensions due to fixed costs (engineering, mobilization). This estimate includes structure, foundation (often helical piles), high-performance insulation suited to Canadian climates, and interior finishing. While the price per square foot is higher than new construction, compared to a full multi-storey addition (often $150,000+), a micro-extension limits overall budget impact while addressing a specific space constraint.

Are you finding yourself hoarding more and more stuff, are your kids getting older, and moving out yet your house is shrinking in front of your eyes? If your home no longer meets your needs in terms of space, maybe it’s time to consider a home extension or addition project. Maybe a kitchen extension, storage area, or a new family room is in the books.

Whether for your growing family, for the arrival of a long-term house guest, or simply due to a lack of space, the reasons behind building a home addition are plentiful. Amongst the many possible solutions presented to those wishing to build a home extension, there is the home addition on screw piles.
