Arkéa Flex

What Arkéa Flex does

Arkéa Flex is a French PropTech startup and wholly-owned subsidiary of Crédit Mutuel Arkéa, a major French bancassurance group. The company has developed a patented modular building system ("bâtiment évolutif") in which residential buildings are constructed as open floor plates with load-bearing facades and cores and no load-bearing interior partition walls. The system is organized around "alvéoles" (alveoli) — modular units that can be merged or separated through simple dry-construction partitioning work without affecting structural elements or technical ducts. Each alveolus is registered as a separate co-ownership lot, supported by novel legal frameworks including a right of first refusal for adjacent units and a "mémoire de la flexibilité" (flexibility memory) provision intended to preserve evolvability across ownership changes.

The commercial offer targets two B2B segments in France: property developers (promoteurs) such as Nexity, Foncia, Crescendo, Uniti, Tailora, and Izimmo, and social housing providers (bailleurs sociaux) such as Polylogis and Armorique Habitat. The go-to-market combines dedicated enterprise field sales with channel partnerships and is supported by an apartment configurator tool that proposes layouts respecting architectural, regulatory, and financial constraints and tracks project margins in real time. Revenue is generated through licensing of the patented building system and accompanying technical, regulatory, and commercial services, though no standalone pricing or revenue figures are disclosed for Arkéa Flex itself. The company's first completed project, Opération Tempo in Tours with Foncia (inaugurated February 2024), is described as the first fully modular co-ownership building in France; a second Paris project with Crescendo and MU Architecture covers 114 residential units, and a Nexity collaboration was announced in 2025.

Core offering

Arkéa Flex provides a patented modular/evolvable building system that allows residential buildings to be constructed with open floor plates, load-bearing facades and cores, and no load-bearing partition walls, so individual apartments (alvéoles) can be combined or separated through simple dry partitioning work. The offering is delivered to French property developers and social housing providers together with dedicated technical, regulatory, and commercial support and a proprietary apartment configurator tool. Each alvéole is structured as a separate co-ownership lot with right of first refusal on adjacent units, supported by a 'mémoire de la flexibilité' clause.

Product overview

Arkéa Flex is a PropTech startup that has developed a patented modular building system for evolvable (évolutif) real estate. The core offering consists of the Bâtiment Évolutif system with its proprietary Système d'Alvéoles, which enables buildings to be constructed as free-form floor plates without load-bearing interior walls, allowing units to be combined or divided through simple dry partitioning work. Each alveole functions as an independent co-ownership lot with legal protections like right of first refusal. The Configurateur d'Appartements is a complementary algorithmic tool that optimizes unit allocation during commercialization by verifying regulatory compliance and financial margins in real-time. The company also provides dedicated technical, regulatory, and commercial support services targeting property developers (promoteurs) and social housing providers (bailleurs sociaux). Arkéa Flex is an innovation of Crédit Mutuel Arkéa, a major bancassurance actor in France with over 11,000 employees, 2.5 billion euros in revenue, and approximately 5 million clients.
