What Charles-Henri Tachon does

Charles-Henri Tachon, architecture & paysage is a French architectural and landscape design practice founded in 1999 by Charles-Henri Tachon, a Paris-Tolbiac graduate (1996) and Architecte D.P.L.G. The firm operates three offices across France — Paris (headquarters, 10 bis rue Bisson, 75020), Mercurey in Bourgogne (Rue de Champ Ladoit, 71640), and Nantes (16/18 rue François Evellin, 44000) — and employs approximately ten collaborators, all qualified architects (Architectes DE-HMONP) drawn from leading French architecture schools including Strasbourg, Marne-la-Vallée, Montpellier, Saint-Etienne, Paris Belleville, and ENSP Versailles.

The firm's core offering is project-based architectural and landscape design services across residential housing (500+ units completed or under construction for public and private clients), public facilities (covered markets, school cafeterias, university buildings), and landscape projects. Named projects include Rue Mousset Robert (Paris 12e), Ilot des Avelines (Saint-Cloud), the Trait d'union building (Paris 14e), Caserne de Reuilly (Paris 12e), and the Pavillon Laprade rehabilitation at the Cité Universitaire Internationale de Paris. The service is delivered through direct client engagement, public architecture competitions, and professional referrals, with revenue generated via project-based professional services fees.

The client base is bifurcated between public-sector maîtres d'ouvrage (municipalities, universities, government bodies) and private developers. The firm's reputation is anchored by two Équerre d'Argent recognitions (2019 win, 2024 nomination), the 2022 Architendance award, and publication in L'Architecture d'Aujourd'hui. The practice is founder-owned, with no parent company, institutional investors, or external capital, and operates exclusively within the French market.
