Frequently asked

What our clients ask.

What happens in the first consultation?

Bring your ideas, photos, inspiration, or simply your questions. We will discuss your home, priorities and possible next steps. No preparation is required.

How much does residential interior design cost?

Design fees depend on the scope and level of support required, from one room to a full-home renovation. During the consultation, we discuss your goals, investment range and the most practical way to move forward.

Do you work with our contractors or yours?

Both. We produce clear drawings any good contractor can execute, and we can recommend trusted partners proven on our worksites.

Where do you work?

Across Greater Montreal (Montreal, Laval, South Shore, North Shore) and throughout Quebec, for example for a cottage or a second home. The 30-minute consultation happens online or on site, depending on your project.

Do you also handle the construction?

We design and we stay involved. The work is carried out by a contractor, yours or one of our trusted partners, with our site follow-up through the final details.

How long does a project take?

A kitchen: typically 2 to 4 months from concept to delivery. A major renovation: 6 to 12 months. The timeline is set at concept stage and closely tracked.

Next step
