Une Pièce en Plus

Une Pièce en Plus operates 36 self-storage facilities across Île-de-France, with nine centres located in Paris itself, plus locations throughout the region including Seine-et-Marne, Yvelines, Essonne, Hauts-de-Seine, Seine-Saint-Denis, Val-de-Marne, and Val-d'Oise. The company was founded in 1997 and is part of the Safestore group. It serves both personal and professional clients, including students, people moving house, those undergoing renovations, and businesses needing archive or stock storage.

Storage units range from 1 m² (telephone box size, for baggage) through to 50 m² or larger for commercial enterprise needs. Each unit comes with individual access—you hold the only key. Rental contracts require a minimum 30-day commitment with no mandatory long-term duration; tenants can exit on 14 days' notice. All centres are accessible 7 days per week and feature 24/7 video surveillance and anti-intrusion alarms. Pricing varies by unit size and centre location, with peripheral locations generally cheaper than central Paris. Free quotes are available through the website or by phone. The company reports a 4.8 out of 5 rating on Google from over 10,000 customers and a 92 per cent satisfaction rate based on customer surveys.
