HH Construction

Home additions in Montreal

Adding on often costs less than moving. We run the whole job, from foundations to the last coat of paint, and tie the new space into the old so it looks like it was always there.

FAQ

Your questions

Do we need a permit for an addition?

Always. Plans must be prepared by a professional and approved by your borough or city. We help you through the application.

Who draws the plans?

An architectural technologist or an architect. If you don’t have one, we can suggest some.

Can we live in the house during the work?

In most cases, yes. The opening into the existing house is made at the end, once the new space is closed in.
