Strong returns.Easy management.
We secure and equip self-storage facilities — the construction of the units is delivered with our partner companies.

One of the most resilient real-estate investments in Europe.
Self-storage has become one of the most resilient real-estate investments in Europe. Occupancy rates run above 85%, and gross yields typically range from 12% to 15% depending on location — well ahead of traditional residential rental.
85%+
Sustained across the European market.
12–15%
Depending on location. Well ahead of residential rental.
Flexible contracts
Short commitments and simple terms keep the asset liquid and the tenant mix easy to refresh.
Controlled operating costs
Few staff, low maintenance load and predictable running expenses on a building that mostly looks after itself.
Structurally strong demand
Demand is driven by long-term shifts in how people live and how businesses hold stock, not by a cycle.
A rare combination of stability and performance.
Everything that secures and equips a facility.
Coroni installs and maintains the systems that secure a self-storage facility: access control, CCTV, fire safety, intrusion detection and electrical equipment. The construction and fit-out of the units is delivered with partner companies.
Modular structures
Load-bearing modular systems laid out to the footprint you already have, sized for the unit mix that pays best.
Partitions
Partition walls that split the volume into rentable units and can be re-cut later as demand shifts.
Secure doors
Roller and swing doors specified for daily tenant use and for the security rating the site needs.
Access control
Per-unit and perimeter access control — the discipline Coroni has installed across France since day one.
CCTV
Camera coverage designed with the layout rather than bolted on after it, so there are no blind corridors.
Fire safety
Detection, alarm and signalling — installed with the partitioning rather than after it, so dividing the volume into bays leaves nothing uncovered.
Intrusion detection
Perimeter and volumetric detection tied into the access control, so an authorised opening and a break-in do not look alike.
From site study to handover.
Step 1: Site study
We survey the existing building or plot and establish what the volume can actually yield.
Step 2: Design
Unit mix, circulation, structure and security are drawn as one scheme rather than four separate trades.
Step 3: Installation
Structures, partitions, doors, access control and CCTV are installed and integrated by our own teams.
Step 4: Handover
You take delivery of a facility that is ready to let, commissioned and documented.
A finished facility, outside and in.
