Segond-Guyon Architectes

What Segond-Guyon Architectes does

Segond-Guyon Architectes is a private architecture firm headquartered in Lyon, France, founded in 2004 by Guillaume Segond (EPFL Lausanne, 1999) and reconstituted in 2008 as a partnership with Claude Guyon (Ecole d'Architecture de Grenoble, 1999, trained at the Cra-Terre earthen architecture laboratory). The firm employs approximately 10–11 people, including HMONP-qualified architects, a UTBM-trained engineer and an administrative assistant, and operates as a boutique design studio rather than a scaled practice.

The firm's core offering is professional architectural services delivered across the project lifecycle — competition entry, schematic and detailed design, and construction supervision — covering seven primary service areas: French international schools (Lycées Français in Sydney, Abu Dhabi, Nouakchott, Lomé, Brasília), embassy and diplomatic compounds (French Embassy in Accra, diplomatic campus in Jakarta), heritage restoration (Palais des Gouverneurs, Lomé; Hôtel de la Villéon Relais & Châteaux), public educational infrastructure (Groupe Scolaire E. & R. Badinter in Bron, ESAD Grenoble), sports facilities (Gymnase Armand, Villeurbanne), judicial facilities (Nouveau Palais de Justice, Lyon), and cultural buildings. Approximately 50% of firm activity is international/export-driven, with active projects spanning Western Europe, West Africa, the Middle East, Southeast Asia, Oceania and South America.

Revenue is generated on a project-based, quote-driven professional services model via direct participation in French public architectural competitions and direct commissions from institutional clients such as the French Ministry of Justice, the French Ministry of Foreign Affairs, AEFE, and local authorities (Villeurbanne, Bron). Distribution is conducted through the firm's project portfolio website and AFEX (Architectes Français à l'Export) network membership, with no formal marketing channels or standardized public pricing. Operating geographies span France, Australia, Ghana, Mauritania, Indonesia, UAE, Togo and Brazil, anchored by a single Lyon office at 4 rue Victor Lagrange.
