What K&+ Architecture Globale does

K&+ Architecture Globale is a multi-disciplinary architecture firm founded in 2006 in Strasbourg, France, operating as a SARL with six associates and approximately 51 collaborators pre-merger. The firm delivers comprehensive architectural services spanning conception, BIM Management, construction economics, and environmental consulting across residential, healthcare, commercial, and urban planning sectors, organized into five specialized poles (Conception, Réalisation, Économie, Administration, and R&D). Its subsidiary KUB architecture & design provides interior architecture, space planning, furniture selection, and decorative arts services, enabling integrated exterior-to-interior delivery.

The firm has built differentiated expertise in two segments: sustainable certified housing (Passivhaus, BBCA, NF Habitat, HQE) and specialized healthcare/social facilities, particularly for autism and disability care — a niche where it holds the national Prix du Projet Citoyen 2021 and recurring commissions from AEDE. Its revenue model is project-based professional services fees, with project acquisition driven by architectural competition participation, direct commissions from approximately 20 recurring developer and institutional clients (Bouygues Immobilier, Néolia, Batigère, AEDE, Ophéa, Habitation Moderne, Opydia, Marignan), and a stable ecosystem of 18 partner engineering firms. Marketing is conducted through industry events (MIPIM, SIMI, Salon Immobilier Grand Est), editorial coverage in D'A, Archistorm, and AMC, and active leadership in Unsfa and Untec professional associations.

On January 1, 2026, K&+ merged with Studio Gardoni to form PASSAGE architecture groupe, a 62-collaborator entity operating from Strasbourg and Lyon, explicitly oriented toward projects of national and European scope. The firm has no disclosed external investment, operates as a founder/associate-owned entity with €10,000 registered capital, and has no disclosed revenue figures — though a D'A magazine ranking of 170th by revenue among French architecture firms (with a 42-place year-over-year improvement) signals a mid-tier but rising market position in the Grand Est region.
