about
PDA Architecture is an architecture and interior architecture firm based in Paris since 2002. Led by Donatien Dalous, architect and environmental engineer, it works on the refurbishment, restructuring and vertical extension of office and hotel buildings. Its name, Partners & Dalous Architecture, reflects a way of working: in close partnership with clients, engineering consultants and contractors.

The studio develops bespoke projects, in line with the uses, technical constraints and identity of each client. Every project is born of a dialogue between aesthetics, functionality and precision of execution. From design to site, the team pays particular attention to details, materials and the experience of future users, to create spaces that are sustainable, sensitive and contemporary.

Our premises on avenue de l'Opéra are designed as an extension of our practice. From the worktable where sketches are born to the material library, where materials are displayed in the light, every space reflects how we design. This is where ideas take shape before reaching the construction site.
A team of 33 people, based on avenue de l'Opéra and organised into three complementary departments.
