Deloitte University, Bailly-Romainvilliers

Architect: Dubuisson Architecture

Wood type: Larch and European pine
Dimensions: Linear open 15x63 mm with a 22 mm joint
Finish: In custom colour

Located in Bailly-Romainvilliers, just outside Paris, the Deloitte University EMEA has opened its doors — an international training campus focused on continuous learning in a modern, inspiring setting. The project — led by Dubuisson Architecture and with a construction budget of over €65 million — draws inspiration from classic French estates. The use of authentic materials like terracotta and wood creates a natural synergy between architecture and landscape, reinforcing the building’s sustainable identity.

Sustainable, aesthetic and acoustic solutions by Hunter Douglas Architectural

The interior material choices align with the project’s aesthetic and sustainability ambitions. In the entrance hall and circulation areas, sustainable wall and ceiling systems by Hunter Douglas Architectural were installed, made from solid wood and aluminum.

The spacious interiors convey openness and comfort. To enhance the warm, natural atmosphere, Hunter Douglas Architectural supplied approximately 6,500 m² of Derako® solid wood linear systems: around 4,000 m² for ceilings and 2,500 m² for wall cladding, using larch and European pine. Two larch finishes were used — one with a transparent terracotta varnish and the other with an oak-look finish — playfully combined to create variation. The pine, finished in white (RAL 9003), was applied to walls in the circulation zones and predominantly on the suspended ceilings of the auditorium.

In addition, around 2,500 m² of Luxalon® Tavola™ aluminum baffles were installed in the “Town Square” relaxation zone and adjacent corridors leading to the restaurant, classrooms, and auditorium.

Acoustic comfort and technical challenges

Acoustic performance was a key requirement for this project. The solutions provided by Hunter Douglas Architectural easily met these demands.

The construction site also posed significant technical and customization challenges. The wooden wall and ceiling systems required specific solutions for column cladding, and complex triangular elements were realized. Numerous invisible inspection hatches were developed for this project as well, enabling maintenance without compromising the design.

Certified sustainability

Deloitte University EMEA has been awarded several leading sustainability certifications, including BREEAM Excellent, WELL Gold, and Cradle to Cradle. The project also won the 2023 MIPIM Award for ‘Best Alternative Project’ and the 2024 Trophée Économique Val d’Europe.
