Selected work

A portfolio of lived-in rooms.

Each project is a study in proportion and patina — designed to age well and read effortless on day one and year ten.

Full renovation

Rosedale Townhouse

A four-storey Victorian reopened around a central oak stair, with limewashed walls and reclaimed Burgundy stone underfoot.

Furnishing & styling

Lakeshore Penthouse

Forty-second-floor glass softened with bouclé, travertine, and a custom 4-metre walnut dining table seating ten.

Interior architecture

Mile End Loft

A former textile floor stripped back to brick and timber, then re-planned into a single flowing 200 m2 family space.

Ground-up build

Forest Hill Family Home

Five bedrooms organised around a courtyard of birch, with warm plaster, brushed brass, and oak throughout.

Compact renovation

Old Montreal Pied-a-Terre

Sixty-eight square metres reworked with full-height joinery and a hidden kitchen behind cerused ash doors.

Full service

Niagara Vineyard Retreat

A weekend house wrapped in linen, lime, and local clay tile, framing the escarpment through steel-and-glass openings.

What we do

Three ways to workwith the studio.

From load-bearing decisions to the last cushion, we hold the whole composition. Engagements are scoped to your home, not a template.

Full-service design

Concept to keys. We lead architecture, joinery, finishes, furnishing, and install — a single point of judgement from first sketch to final styling.

Interior architecture

We reshape how a home is inhabited — walls, light, circulation, and millwork — drawing the bones before a single fabric is chosen.

Furnishing & styling

For finished spaces that feel unfinished. We curate furniture, art, lighting, and textiles into rooms that finally settle.

Bespoke joinery

Kitchens, libraries, and built-ins drawn to the millimetre and made by hand in our partner atelier in cerused oak, ash, and walnut.

Sourcing & procurement

Trade access to 300+ European and Canadian ateliers, with one purchase order, one delivery window, and one accountable studio.

Art & objects

We place commissioned and collected pieces last — the layer that turns a well-built room into a home with a point of view.

In their words

The studio our clients keep coming back to.

Maison Cle saw a home in our house that we couldn't. Three years in, every room still feels exactly right — nothing we'd change, nothing we tire of.

Helene & David Marchetti
Rosedale Townhouse

They protected the budget as fiercely as the vision. One contact, one timeline, zero finger-pointing. We've already hired them for the cottage.

Priya Sundaram
Lakeshore Penthouse

I've worked with architects who draw beautifully and decorators who style beautifully. Maison Cle is the rare studio that does both, in one voice.

Before we begin.

What size of project do you take on?

Full-service residential engagements typically start at $150K CAD in construction and furnishing combined. We also take focused furnishing or joinery commissions on finished homes.

How long does a home take?

A full renovation runs 9 to 16 months from first concept to install — design and procurement up front, build and styling after. We share a realistic, padded timeline before you commit.

Do you work outside Toronto and Montreal?

Yes. Roughly a third of our work is in Niagara, the Laurentians, and Muskoka, plus the occasional pied-a-terre abroad. Travel is built into the proposal.

Can you collaborate with our architect or builder?

Often. We're happy to lead the interior alongside your existing team, or bring our trusted contractors and trades when you'd prefer a single accountable studio.

How do we start?

With a paid discovery session at your space. We listen, measure, and return a tailored proposal with scope, phasing, and an honest budget — no obligation to proceed.

Tell us about your home.

We take on twelve projects a year. Share your space and timeline, and we'll tell you honestly whether — and how — we can help.
