What Séquences does

Séquences, Architecture et Urbanisme is a Toulouse-headquartered French architecture and urban planning firm that has operated as a SARL since at least the mid-1980s, founded by partners — Antoine Fleuriot (engineer), Pascale Lecumberry (architect), and Jérôme Terlaud (architect) — who first collaborated on Toulouse's first metro line competitions. The firm employs approximately 40 professionals organized into four specialized poles (Conception, Économie, Réalisation, Administration), with its headquarters at 51 bis rue des Amidonniers in Toulouse and a secondary office at 15 rue Traversière in Paris. Its practice is explicitly generalist: the firm deliberately works across diverse building typologies — healthcare (hospitals, EHPADs, mental health centers), education (schools, high schools, universities, research facilities), mobility infrastructure (cable cars, parking, transit hubs), residential housing, tertiary/industrial facilities, and cultural/sports venues — to enable cross-pollination of solutions across programs. The firm deploys Building Information Modeling (BIM) selectively for project coordination and synthesis (e.g., Bâtiment Numérique, Equipement mutualisé Rigal), but does not develop or commercialize proprietary technology platforms.

The firm's reference portfolio includes the €93M Téléo urban cable car in Toulouse (delivered 2022 alongside Mandataire Poma), the €56M Urgences Réanimation Médecines building at CHU de Toulouse (delivered 2015), the €26.1M Espace Clément Ader research facility for ISAE SUPAERO (delivered 2013), the €24.9M Lycée Martin Malvy in Cazères (BEPOS and E4C1 certified, delivered 2020), the €19M Crédit Agricole Nord Midi-Pyrénées headquarters (2023 competition win), the Airbus Terminal D at Colomiers (BREEAM Excellent, delivered 2023), and the €23.8M Centre Hélo-Marin for Centre Hospitalier de Perpignan (delivery expected 2026, winner of the 2023 MNH/UAFS Quality of Life and Working Conditions 1st Prize). Séquences holds long-term implementation partnerships with Poma (mobility/industrial consortium work) and Eiffage Construction (parking, residential), and collaborates with peer firms such as Fontaine & Malvy and Art & Build on specific mandates.

Séquences generates revenue through project-based professional service fees — design, engineering coordination, urban planning, and project management — acquired primarily via competitive public procurement (concours) and direct client engagement with institutional buyers. Pricing is project-specific, determined by scope, surface area (SDP/SHON), mission type (mission de base, OPC, synthesis), and complexity, with no publicly disclosed rate card; typical project values range from €3.5M to €93M and span 2–5 years from conception through construction delivery. The customer base is predominantly French public-sector — regional councils, municipalities, university hospitals (CHU), universities, and mobility authorities — with select private-sector clients including Airbus and Crédit Agricole Nord Midi-Pyrénées. The go-to-market is sales-led, relationship-driven, and dependent on institutional procurement cycles; geographic coverage extends across at least nine French regions plus French Guiana (Kourou). Marketing is limited to a portfolio website (sequences.fr), LinkedIn, Facebook, and Instagram, with no evidence of paid advertising or systematic outbound demand generation.
