01 — Warmth
An Embrace
Every space we design should feel like one. Livable, layered, and full of life — never cold, staged, or intimidating.
A boutique interior design studio. Rooted in Palm Beach — working with clients across the United States.

— A Quiet Tribute
Trois — French for three — is a quiet tribute to our founder, one of three sisters raised in a home where warmth was not decorative, it was structural. Trois Hous is her life's work made visible: spaces that hold people the way a family holds each other.
We bring that sensibility to every kind of space we touch — private residences, boutique offices, multifamily amenity floors, and the occasional auto garage that wants to feel like more than a garage. We draw on a Mediterranean-organic vocabulary — arched doorways, natural stone, aged brass, handmade tile, living greenery — and ground it in the particular light and energy of Palm Beach, Florida.
— Warm. Crafted. Rooted.
— What We Believe
01 — Warmth
Every space we design should feel like one. Livable, layered, and full of life — never cold, staged, or intimidating.
02 — Craft
The texture of a zellige tile. The weight of unlacquered brass. The curve of an arch. Craftsmanship is never optional.
03 — Story
Great design tells the story of the people inside it. We listen deeply before we draw a single line.
04 — Roots
We are Palm Beach — not visiting it. Our local knowledge, relationships, and presence are advantages we extend to every client.
05 — Light
Florida light is a design material. We use it intentionally — through arches, open plans, natural stone, and palettes that glow.
06 — Three
Our origin is rooted in threes — three sisters, one vision. Every project: client, space, and designer in collaboration.
— What We Design
The complete design journey — discovery through final installation — for private homes, estates, and high-end condominiums.
Boutique offices, professional suites, and family offices — designed with the warmth and craft of a residence, the discipline of a workplace.
Lobbies, lounges, fitness, pool decks, and resident clubs — amenity floors that lease the building and feel like an extension of home.
For the garage that wants to be more than a garage — collector storage, showroom, and lounge, designed with the same craft as the house.
Discovery calls, design audits, strategy sessions — and pre-sale staging programs for agents, brokers, and developers across Palm Beach.
— The Process
Phase 01 — Discovery
Site visit, brief, and a mood board grounded in your life — not a template. We learn how you live, how you host, and how the light moves through the rooms.
Phase 02 — Development
Space plans, elevations, finish specifications. Materials curated from our trade vendors and visited in person whenever possible. Every selection considered against the whole.
Phase 03 — Installation
Procurement, contractor coordination, install, and final styling. We manage the chaos so you arrive to a home that feels — from the first moment — already lived in and loved.
— A Note from Our Founder
"Palm Beach is not just where we work. It is where we are rooted. Every arch, every tile, every fixture is a decision we make together — yours, first."
We are not the biggest firm in the market. We are the most personal. Every project is led by our principal. Every space is designed with the specific people inside it in mind. That is not a positioning strategy — it is a promise.
