CALQ's design teams work on different types of new or rehabilitation operations, both on tertiary projects (Kléber Etoile, 14 Londres, Art&Co) and on works dedicated to retail (Galeries Lafayette Detaxe, Forum des Halles, Les Eleis shopping centre), as well as housing and equipment operations (UNESCO, Théâtre Traversière).

A centre dedicated to interior architecture works on the enhancement of the noble areas of the projects (Covivio headquarters, offices of the Departmental Council 92), as well as the interior design of luxury hotels and apartments (Hôtel Le Claridge).

CALQ is also increasing its collaborations with fellow architects on the French and international scene (RCR Arcquitectes, David Chipperfield, Michael Green, Studios Architecture, Franklin Azzi, etc.) for the realization of large-scale mixed projects (Cultural Project on Île Seguin in Boulogne-Billancourt, Morland Mixité Capitale in Paris), as well as with designers such as Ora-ïto (Pathé cinemas, Hotel YOOMA), Studio Jean-Philippe Nuel, Tristan Auer, Samuel Nageotte.
