What SEPTEMBRE Architecture does

SEPTEMBRE Architecture is a Paris-based architectural firm founded in 2010 by three partners — Sami Aloulou, Memia Belkaïd, and Lina Lagerström — operating as a privately-held practice with nine core staff and an extended collaborator network. The firm delivers architectural design services across housing (collective, intergenerational, student), mixed-use programs, cultural and community facilities, educational campuses, urban transformation, and limited hospitality/restaurant typologies, with active projects in France, Sweden, Tunisia, Senegal, and Spain. Its commercial pipeline is sourced primarily through French public and invited architectural competitions, supplemented by direct commissions from institutional clients including RIVP, Paris Habitat, AP-HP, RATP Real Estate, and TBS.

The practice is organized around a defined thematic anchor — domesticity (and specifically the kitchen) as a lever for urban transformation — and a proprietary methodology of "transformation en site habité" that allows complex inhabited renovations without resident displacement. Technical differentiators include 100% wood construction, energy-positive buildings, Nordic Swan ecolabel compliance, and HQE/RE2020 certifications. Noteworthy executed projects include the GENERATORN 112-unit intergenerational housing development in Sweden (€10.23M HT), the 8,000m² CITROËN garage rehabilitation in Paris, the BELLEVILLE collective housing (EU Mies Award 2017 nominee), and the Archipélia community center (Young Swedish Architecture Award 2019).

Revenue is generated through project-based, professional-services commissions with fees negotiated per project. Visibility is built through a project portfolio website, Instagram and LinkedIn presence, architecture exhibitions and biennale participation (Venice 2016 Nordic pavilion), academic teaching at Malaquais, Versailles, and Paris-Est, and an award portfolio spanning FAIRE 2021, Europe 40 under 40 (2018), Young Swedish Architecture Award (2019), and EU Mies Award nomination (2017). No venture-capital, private-equity, or external ownership structures are disclosed.
