Companies lose weeks searching the wrong category. "Warehouse" covers at least four different products that price and behave very differently: the giant <b>big-box</b> distribution shed, the mixed-use <b>flex</b> unit, the manufacturing-led <b>light-industrial</b> building, and the small, expensive, city-edge <b>urban / last-mile</b> box. Here is the honest distinction and who each one is for.
The four types at a glance
Warehouse categories compared
Big-box logistics — 10,000 m²+, 10-12 m clear, many docks - storage & distribution at scale
Flex — 500-3,000 m², warehouse + workshop + office in one, 6-8 m - SMEs, trade, e-commerce
Light-industrial — Making, assembling, repairing; heavy power & floors; some office
Urban / last-mile — Small units close to the city; highest rent per m²; fast delivery
Big-box logistics
A single-purpose distribution warehouse, usually 10,000 m² and up, with 10-12 m clear height, one dock per roughly 1,000 m², deep HGV yards and a floor built for high racking. It suits 3PLs, retailers, manufacturers and e-commerce players moving pallets at scale. You commit to a long lease (typically 5-10 years) and judge it purely on the operational specs, not on looks.
Flex
The all-rounder: a 500-3,000 m² unit that combines warehouse, a bit of workshop and a small office fit-out under one roof, usually with 6-8 m clear height and one or two docks or a level access door. It suits SMEs, trade counters, e-commerce fulfilment, wholesalers and light assembly - anyone who needs storage plus a few desks without paying for a big-box they cannot fill. Flex is the most common requirement by number of tenants.
Light-industrial
A production-led building for making, assembling or repairing things, where the storage is secondary. What matters here is heavy power (three-phase, high amperage), a strong floor, ventilation, drainage and sometimes cranes - plus a modest office. It suits manufacturers, engineering firms and workshops. It overlaps with flex but is defined by the process happening inside, not just storage.
Urban / last-mile logistics
Small warehouses close to or inside the city, used to hold stock near customers for same-day and next-day delivery. Land scarcity makes these the most expensive per m² of any warehouse type - often a clear premium over big-box on the motorway ring - but they buy you speed and lower final-leg transport cost. They suit grocery, parcel, pharmacy and e-commerce delivery operations.
How to choose in one line
- Moving pallets at scale? Big-box logistics - optimise for clear height, docks and motorway access.
- Need storage plus a workshop and a few desks? Flex - the cheapest way to get a bit of everything.
- Making or assembling things? Light-industrial - power, floor and services matter more than height.
- Need stock near customers for fast delivery? Urban / last-mile - pay the premium for proximity, keep the unit small.
