What a Home Addition Involves

An addition affects several aspects of your property. Here's what to plan for:

Freshly poured concrete foundation walls for a new house set against a grassy field and blue sky.

Structure and Foundations

Depending on the type of extension, the work may require full foundations, a concrete slab or helical piles. The team assesses the load-bearing capacity of your existing structure before recommending an approach.

Utility Connections

Electrical, plumbing, heating and ventilation systems must be extended to the new space. This work is coordinated with specialized subcontractors.

Building Envelope

The cladding, insulation, doors and windows of the new space must integrate with the existing structure, both visually and in terms of energy performance.

Permits and Compliance

A building permit is mandatory in Quebec. Some projects may also require architectural or engineering plans depending on the scope of work and your municipality's requirements.
