UMAN architect establishes a presence in the Grand Duchy of Luxembourg

15 September 2026

UMAN architect takes a new step in its development by welcoming Extenso, a Luxembourg-based architecture firm founded in Hobscheid 20 years ago.

This new chapter brings together two teams, complementary expertise and a shared commitment to architectural quality, listening and collaboration.

Founded by Damien Hublet, Extenso has built up solid experience over the years in supporting projects in the Grand Duchy of Luxembourg. Damien will continue to lead the team on a day-to-day basis, alongside Amélie Lessire, who is now an associate architect.

With this integration, UMAN architect strengthens its presence in Luxembourg and now brings together around forty employees across Bierset, Marche-en-Famenne and the Grand Duchy.

A new location, new complementarities and the same ambition: to design high-quality architecture that puts people and places at the heart of every project.
