Second-storey addition
A common solution for Crawford Park's post-war houses and the Sud-Ouest's shoebox houses that are short on bedrooms. The existing structure is checked first.

Home additions in Verdun and the Sud-Ouest
Add a storey, extend toward the back or open up the roof with dormers. We manage your addition from the zoning review to the finishing touches.
Home additions
Types of additions
Rear addition
A bigger kitchen, a family room or a ground-floor bedroom, by extending the house into the yard.
Dormers
Turn the space under the roof into livable rooms, with more headroom, light and usable floor area.
Side extension
An office, an entry vestibule or an extra room on the side, depending on your lot's setbacks.
What we check before we start
A successful addition starts with what the bylaws allow on your lot. Each borough sets its own rules, and two neighbouring houses don't always have the same options, for example on a corner lot.
We do these checks before giving you a price, so the quote matches a project that can actually be built.
- Height, setbacks and footprint allowed by the borough
- Capacity of the existing structure and foundations
- Architect's plans and engineering calculations required
- Building permit application
- Tie-in to the existing roof, plumbing and electrical

Frequently asked questions
What people often ask us
Do I need a permit to build an addition in Verdun?
Yes. An addition requires a building permit from the borough, with plans. We prepare the application with your professionals.
How long does an addition take?
It depends on the scope of work and on permit delays. You get a schedule with the quote, and we keep it updated during construction.
Can you add a storey to a shoebox house?
Often, yes: we built a second storey on a shoebox house in Ville-Émard. Some boroughs protect these houses, though, so we first check the rules that apply to yours.
Can we live in the house during the work?
Often yes for a rear addition. For a second storey, it depends on the project. We discuss it at the first visit so you can plan ahead.
