Didier Demonchy, creator of the Locabox brand in 2007, made his mark on the self-storage sector with a clear vision: to offer modern, accessible storage solutions adapted to new consumption patterns. Within a few years, he structured and deployed a network of 27 Locabox centers, all operational today throughout France, thanks to a successfully finalized strategic investment.

Building on this success, Didier Demonchy co-founded DUOCLOSE alongside Jean-Baptiste Berenguer to meet a new market need: to support project developers in the creation or transformation of self-storage centers, by offering them a complete, flexible, and reliable technical solution.

This new venture is based on solid field experience, acquired in all dimensions of self-storage: from land acquisition to technical design, from space optimization to operational management. DUOCLOSE thus inherits unique expertise, built on dozens of projects carried out with high standards, mastery, and responsiveness.

Today, DUOCLOSE acts as a global technical partner, capable of constructing a closed and covered building, providing custom interior fit-outs, and supplying professional equipment (locks, doors, access systems). This integrated approach allows investors, operators, or developers to secure their project while maximizing profitability.

With DUOCLOSE, every project benefits from the expertise of a practical, grounded player, capable of anticipating needs, advising with precision, and executing with rigor. Expertise born from the field, serving your ambitions.
