Discover our services →Every architectural project rests upon the convergence of ambitions, constraints and expertise. Construction management consists in orchestrating these elements — securing each stage, anticipating risks and ensuring execution in accordance with established standards of practice.
OPUS coordinates all project stakeholders, oversees the quality of works, manages the programme and ensures compliance with financial commitments. By entrusting the delivery of your project to our practice, you benefit from comprehensive and structured oversight, from design through to practical completion and the defects liability period.
These services are at the heart of our profession: transforming an intention into a completed work, faithful to your expectations, delivered under the conditions agreed.


Adrien Marquet
Founder of OPUS
For more than fifteen years, he has shaped projects with the same exacting standards one brings to an enduring work: understanding a place, listening to a need, then translating an intention into built reality.
His career has been forged on site, in close contact with buildings, materials and the people who bring them into being. Each project is approached as a unique composition, where technical precision, the balance of forms and the mastery of detail converge.
From the earliest sketch to the completed building, he accompanies his clients with a comprehensive vision, ensuring the coordination of all stakeholders and the fulfilment of every commitment made. His work reflects a constant pursuit of accuracy, functionality and harmony.
Today, drawing on fifteen years of experience, he designs and manages projects that unite aesthetic ambition, durability and constructive precision, within a relationship founded on trust and transparency.
