What Une Pièce en Plus does
Une Pièce en Plus is a French self-storage operator founded in 1997 and headquartered in Rueil-Malmaison, operating the densest self-storage network in the Île-de-France region with 36 centres, including 9 inside Paris. The company serves both individual consumers (people moving, renovating, decluttering, and students) and businesses (SMEs, e-commerce operators, artisans, flea-market dealers, and multi-site enterprises) by renting secure storage units ranging from 1 m² to over 50 m², with units up to 100 m² available for large commercial requests. Pricing is month-to-month with no minimum commitment, ranging from approximately €52/month for a 1–3 m² unit to €528/month for 20+ m² units, plus mandatory insurance and on-site packing supplies.
The core technical platform consists of physical storage infrastructure secured by app-based and badge-based access control (06:00–23:00 in over 20 centres), 24/7 CCTV with remote surveillance, intruder alarms, fire protection systems, and a customer-only personal lock protocol. Customers transact primarily through a self-serve digital channel (online quote and centre finder on the company website), with phone-based inside sales and on-site advisors providing support. There is no public API, SDK, or AI/ML capability.
Une Pièce en Plus generates recurring revenue through subscription-based storage rentals paid by SEPA direct debit, mandatory insurance attached to every contract, and ancillary one-time sales of packing materials. The company has been a wholly owned subsidiary of Safestore Holdings PLC (LSE: SAFE) since July 2004, giving it access to the parent group's operational scale across 200+ European centres. Distribution is wholly direct-to-consumer via company-operated sites, with cross-promotional partnerships with Europcar and Des Bras en Plus adding relocation-adjacent services.
