Industrial Open Storage (IOS)
Leading professionals here to help you rent, let, buy and sell open storage land and provide you with the best advice on this new industrial asset class.
Overview
Industrial Open Storage (IOS), also known as open storage sites, open storage land or industrial land to let, has become one of the fastest-growing sectors of the UK industrial property market.
These strategically located sites play a critical role in supporting logistics, infrastructure, utilities, construction, transport and distribution businesses, providing the space required to store materials, equipment, vehicles and operational assets.
As demand for well-connected industrial land continues to increase, occupiers are seeking higher-quality open storage sites with secure boundaries, durable surfacing and excellent transport links.
This shift has transformed Industrial Open Storage from a niche property type into an established and highly investable asset class, attracting institutional investors, developers and occupiers across the UK.
With strong occupational demand, limited supply and growing rental values, IOS has become a key component of the modern industrial and logistics market.

What Is Open Storage?
Open storage sites are parcels of land used for the open storage of materials, equipment, vehicles and infrastructure assets.
Common uses include the storage of construction materials, scaffolding, plant machinery, containers, utility equipment, battery energy storage systems and engineering components.

How We Can Help
Acquire and Develop Open Storage Sites with Carter Jonas
Finding the right open storage site in the right location can be critical to long-term operational and investment success. Our dedicated IOS team proactively identifies both on-market and off-market opportunities through an established network of agents, landowners and industry contacts.
Using market intelligence, transaction data and occupational demand analysis, we identify areas where rental growth, infrastructure investment and occupier requirements are driving increased demand for open storage sites.
Once opportunities have been identified, we manage the acquisition process from initial site sourcing through to negotiation and completion, working closely with purchasers, vendors and professional advisers.
Our team also advises on strategies to enhance rental income and asset value. This includes assessing site improvements, reviewing occupier requirements, applying the IOS Four-Tier Classification System and determining the most effective letting strategy, whether for a single occupier or a multi-let open storage site.
