Building a villa in Saint-Barthélemy
Biophilic tropical sanctuaries, designed for hurricane resilience and barefoot luxury.
Our reading of the territory
What the island asks of a villa.
Our international destination. Since 2025 we have been designing biophilic villas in Saint-Barthélemy, with structures engineered to withstand category 5 hurricanes while opening fully to the trade winds.
Our international destination. Since 2025 we have been designing villas here that open entirely to the trade winds, yet whose structure is engineered for a category 5 hurricane. The two requirements do not conflict: they are drawn together.
Irma (2017) redefined building on the island: reinforced concrete structures anchored to the rock, roofs with low wind exposure, integrated hurricane shutters, self-sufficient water storage and energy.
Our villas follow the barefoot-luxury principle: through-spaces open to the sea, pools that extend the horizon, native planting that gives shelter from the sun and from view.
All logistics run through the port of Gustavia: we consolidate materials in containers from mainland France and Italy, with a reverse schedule set by the shipping rotations.
The land
Pointe Milou, Lurin, Camaruche, Gouverneur: plots sit on the flanks of hills, steep and with rock close to the surface. Anchoring to the rock, access and rainwater management set the budget long before the living area does.
The way we build
Reinforced concrete anchored to the rock, a roof with low wind exposure, hurricane-rated laminated glass and shutters built into the reveals. Inside, ipe, teak and coral stone, marine bronze for all the ironmongery — salt forgives no compromise on alloys.
Life in the house
Through-spaces open to the sea, a pool that extends the horizon, native planting that provides both shade and privacy. Barefoot luxury comes down to little: a breeze that passes through, a floor that does not burn, filtered light.
Materials & permits
What we use, what we get permitted.
Hurricane resilience cannot be seen: it lies in the load paths, the anchoring and the glazing. It takes nothing away from the openness to the sea — it makes it last.
Reference materials
Contractors and logistics
Structural work and steel frames by contractors based on the island, hurricane-rated joinery and marble consolidated in containers from mainland France and Italy, furniture shipped last. Everything passes through the port of Gustavia: the site schedule is built in reverse, from the shipping rotations.
What we handle for you
- Local planning code of the Collectivity
- Category 5 hurricane resilience
- Sea logistics via Gustavia
- Self-sufficient water & energy
The Collectivity’s code, and the lessons of Irma
Saint-Barthélemy is an overseas collectivity with its own planning code: rules on footprint, height and colour are set locally, and permits are processed in Gustavia. Since Irma in 2017, structural requirements have been redefined: anchoring to the rock, design for extreme wind, systematic protection of openings. As the island has neither a usable water table nor an extensive grid, each villa carries its own cistern, treatment plant and solar production with storage. We prepare the application locally and have the calculations verified by a structural engineering firm approved for hurricane zones.
Application prepared by our Planning & Architecture team before any work is committed.

Projects
What we have built in Saint-Barthélemy.
Every project can be visited by appointment, with our clients’ consent. Areas, timings and materials are those of the signed contract, not of a brochure.

Four months of design, twelve months of permit processing and advance logistics, then twenty to twenty-six months on site. The hurricane season, from June to November, requires the building to be weathertight before summer and lifting to be suspended during alerts.

Frequently asked questions
Building in Saint-Barthélemy, in practice.
Budget, timing, permits, materials: the six questions we are always asked, with the figures for this territory.
What budget should I plan for a villa in Saint-Barthélemy?
New construction in Saint-Barthélemy costs €8,200 – 13,500/m² excl. VAT, Signature finish. For a reference programme of 300 m², that means a budget of €2,730,000 to €4,615,000, including architect, engineering and insurance fees. The Prestige and Palace finishes add 22% and 50% respectively to the base. Our brokerage commission is paid by our partner contractors: it is never passed on to the client.
How long does it take to build in Saint-Barthélemy?
Allow 4 months of design and 3D modelling, 12 months of permit processing — the usual timescale for this territory — then 17 months on site for 300 m². That is about 34 months between the first meeting and the handover of the keys. We commit to this timetable in the contract: 100% of our projects have been delivered on time.
Which planning rules apply in Saint-Barthélemy?
Four points shape every project in Saint-Barthélemy: local planning code of the Collectivity, category 5 hurricane resilience, sea logistics via Gustavia and self-sufficient water & energy. Saint-Barthélemy is an overseas collectivity with its own planning code: rules on footprint, height and colour are set locally, and permits are processed in Gustavia. Since Irma in 2017, structural requirements have been redefined: anchoring to the rock, design for extreme wind, systematic protection of openings. As the island has neither a usable water table nor an extensive grid, each villa carries its own cistern, treatment plant and solar production with storage. We prepare the application locally and have the calculations verified by a structural engineering firm approved for hurricane zones. Our Planning & Architecture team prepares the entire application before any work is committed.
Which materials do you use in Saint-Barthélemy?
Our reference materials are hurricane-rated reinforced concrete, ipe & teak, coral stone, hurricane-rated laminated glass and marine bronze. Structural work and steel frames by contractors based on the island, hurricane-rated joinery and marble consolidated in containers from mainland France and Italy, furniture shipped last. Everything passes through the port of Gustavia: the site schedule is built in reverse, from the shipping rotations.
When can building start in Saint-Barthélemy?
Four months of design, twelve months of permit processing and advance logistics, then twenty to twenty-six months on site. The hurricane season, from June to November, requires the building to be weathertight before summer and lifting to be suspended during alerts. Hurricane resilience cannot be seen: it lies in the load paths, the anchoring and the glazing. It takes nothing away from the openness to the sea — it makes it last.
Do you also renovate in Saint-Barthélemy?
Yes. A major renovation in Saint-Barthélemy — remodelling, envelope, building services and finishes — costs €4,500 – 8,000/m² excl. VAT; interior fit-out alone €2,200 – 4,500/m² excl. VAT. A complete 200 m² remodelling therefore comes to €1,000,000 to €1,825,000 over about 24 months. We renovate villas and prestige apartments in Gustavia, Pointe Milou, Lurin, Camaruche, Gouverneur and Saint-Jean.
