Ardian has taken Casaforte; Nuveen and Safestore hold Easybox. In two years the segment has moved from niche curiosity to declared target for pan-European funds, in a country with the lowest per-capita provision on the continent.
In the first quarter of 2026, Italian alternative asset classes, a category grouping data centres, photovoltaics and self-storage, drew €160 million in investment against €24 million in the same period of 2025. The percentage change is so large as to be uninformative; what matters is that a residual line in sector statistics has begun appearing as a category of its own.
In self-storage the sequence is precise. In late 2024 a fifty-fifty joint venture between Nuveen Real Estate and the British group Safestore acquired Easybox from TPG Angelo Gordon for €175 million, taking on ten operating stores and two turnkey developments. Safestore invested roughly €45 million for its share, the balance funded by joint-venture debt. In March 2026 Ardian acquired the majority of Casaforte, Italy's largest operator by floor area, lifting its total commitment to the sector across Italy, France and Spain beyond €300 million, with a further €200 million planned.
Why here
The investment thesis is explicit and testable. Italy has the lowest self-storage floor area per inhabitant in Europe. Awareness is equally low: according to Ardian's statement, only 12% of the population knows what the service is. In a mature market such penetration would be a demand problem; in a market where the structural drivers are already working, it is headroom.
Those drivers are three, and they push the same way. Urbanisation concentrates population where floor space costs most. Rising residential mobility multiplies the transitions in which temporary storage is needed. Shrinking average unit sizes in major cities have stripped homes of the cellars and box rooms that once absorbed the surplus. Ardian's Rodolfo Petrosino placed the bet on Southern Europe, naming Italy and Spain as the markets where penetration lags despite identical underlying dynamics.
Current scale shows how narrow the perimeter still is. Casaforte runs 24 centres totalling roughly 80,000 square metres, concentrated in the North but present in Milan, Turin, Genoa, Bologna and Rome. Easybox operates twelve centres and 75,000 square metres across Milan, Rome, Turin, Genoa and Florence. Together, the country's two leading operators control less floor area than a single large-format logistics shed.
The economics, and their limits
Self-storage behaves differently from a conventional income asset. Revenue is fragmented across many short contracts rather than concentrated in one tenant, which lowers counterparty risk but removes the multi-year visibility a lease provides. Pricing is dynamic and adjusts to occupancy. Recurring operating costs are modest relative to other operational asset classes, since the service is light on staff and increasingly managed remotely.
Returns depend on the lease-up curve. A new centre stabilises only after years of gradual fill, absorbing capital without full margin in the interim. Safestore estimated a 10% cash-on-cash return on stabilisation for the Easybox portfolio, with a slightly dilutive earnings effect in the acquisition year and accretion from 2027. Casaforte's 2024 accounts, the latest available, tell the same story from the Italian side: production value near €8.9 million, operating costs of €7.5 million, and net profit of €88,000 after more than €1.1 million in financial charges on €25 million of debt.
Two cautions remain. The first is the operational nature of the asset: value rests on management quality and fill rates rather than on contractual strength, which makes valuation less standardisable. The second is regulatory. As with logistics, there is no dedicated national planning framework, and use classification is handled case by case through categories designed for something else, with outcomes that vary between municipalities.
A segment in which two transactions reshape an entire national market is by definition a segment that has not yet reached scale. The relevant question is not whether growth will come, but how quickly pan-European platforms can build a development pipeline within a permitting environment that was never designed to accommodate them.
