Build with confidence.
Owner’s representation & construction management,
in Saint-Barthélemy and on the Arcachon Bay

what we do
Two missions, one single representative.
Owner’s representation
You are leading a project and you want it kept on track: its brief, its budget and its schedule. As your owner’s representative, Lagarde acts on your behalf: we define your needs, we bring the design team together, we make the call on every decision and we make sure each one serves the original ambition of the project, from the first study to the operation of the building.
Construction management
Design is entrusted to the architect of your choice; Lagarde delivers it. From the initial survey to the as-built documentation, we lead the technical studies and the works, we coordinate the contractors and we take delivery of the building, drawing on a knowledge of construction gained in the field, from the Compagnons du Devoir craft guild to the building sites of Saint-Barthélemy.
our method
Anticipate
An exceptional building never happens by chance. It is prepared decision by decision, before work begins on site.
Coordinate
Dozens of stakeholders, technical, administrative and financial constraints: we hold the thread between the architect, the engineers and the contractors.
Secure
We decide, we check, we take delivery. Our job is to turn complexity into peace of mind.

Plans are read on site, with the contractors. That is where the precision of a building is decided.
about
Building an exceptional home should never be a source of uncertainty.
Yet behind every ambitious project lie hundreds of decisions, dozens of stakeholders, and technical, administrative and financial constraints that can undermine the best intentions. We believe that a successful project does not rest on a good idea alone. It rests on the ability to make that idea buildable.
At Lagarde, we stand for a demanding approach to client support. One where technical expertise comes before stylistic effect. Where every choice is guided by use, coherence and durability. Where elegance comes from control rather than display.
Our approach was built in the field. From the Compagnons du Devoir craft guild to the most prestigious projects in Saint-Barthélemy, we have learned that an exceptional building never happens by chance. It is the result of careful anticipation, a deep knowledge of construction and attention to every detail.
We act as our clients’ representative. The partner who coordinates, secures, decides and makes sure every decision serves the original ambition of the project. Because beyond plans and materials, what we create above all is an experience.
A house that works seamlessly. Spaces designed for entertaining. Systems that make everyday life simpler. Comfort you can feel in every detail. Like the finest private estates of Saint-Barthélemy, we create places that offer the discreet refinement of a hotel with the privacy of a personal residence.
Our job is to turn complexity into peace of mind. And to let our clients build with confidence.
“Architectural excellence does not lie only in the beauty of a project. It lies in its ability to be built with precision, control and peace of mind.”
