Inside a small bonded warehouse that is no longer bonded.
What the building does now, and what it used to do. A short report from a corner of the Sheerness industrial estate that has been gradually adapting itself, over the past two decades, to a series of uses none of which were what it was built for.
The building was constructed in 1924, as a small bonded warehouse serving the commercial port. It held, in its working life, mostly imported wine and spirits awaiting customs clearance. The bonded designation was a legal status: goods stored in the warehouse were treated, for tax purposes, as not yet having entered the country. They could be re-exported, blended, or held indefinitely without duty being paid, on the understanding that duty would be paid the moment they left the warehouse for the domestic market.
The building lost its bonded status in 1981, when its operator went out of business and the licence was not renewed. The building was, for the following six years, empty. It has, since 1987, been put to a series of uses by a succession of owners. None of those uses has, by any measure, made full use of the building. The building is, in 2026, somewhere between two-thirds occupied and one-third in a state of polite ongoing decline.
What the building was built for
A bonded warehouse, in its 1920s form, is a particular kind of building. It is built to hold a large quantity of liquid stock, in barrels or bottles, in a controlled atmosphere, with a single point of access for inspection by customs officers. The building has, by deliberate design, very few windows. The walls are thick. The floors are reinforced to take the weight of stacked barrels. The internal layout is open, with a small office at the front, a large open warehouse space behind it, and — at the back, accessible only by a single internal door — a small "tasting room" where the customs officers and the importers would inspect samples of the stock.
All of these features are still, in 2026, intact. The thick walls are intact. The few windows are intact, in their original frames, with the original metal grilles still on them. The reinforced floors are intact, although there are, in two places, signs of subsidence that the current owner has, he tells me, been meaning to look at for some time. The office at the front is intact. The tasting room is intact, although it has not, since 1981, been used for tasting anything.
What the building does now
The building's current uses are, in their way, characteristic of how former industrial buildings in small coastal towns tend to get adapted. The front office is rented, on a long lease, to a small accountancy practice that serves the local trade. The main warehouse space is divided into three: a small theatrical-prop hire business occupies the largest portion; a self-storage operation runs the middle section; and the back third is rented, irregularly, to a series of short-term tenants who need a large unheated space for periods of weeks to months.
The tasting room — the small back room — is, since 2019, used as a workshop by a local boat-builder who specialises in the restoration of small wooden craft. The workshop is, by his account, perfectly suited to the work. The thick walls keep the temperature stable. The natural light, although limited, is even. The room is, he says, the best workshop he has ever rented, and he intends to keep it for as long as the rest of the building remains standing.
"Nothing in here was built for what's in here now. The building doesn't seem to mind."
What this tells us
I have been thinking, since visiting the building, about what it means for a building to be used for things it was not designed for. The bonded warehouse is, in 2026, doing four jobs simultaneously, none of which involves storing imported wine, none of which requires the bonded designation, and none of which would have been understood by the building's original designer as a likely use.
This is not, in itself, an unusual state of affairs. Many of the buildings in any working British port have, by 2026, been adapted away from their original purposes. What is interesting about this particular building is how little adaptation has been required. The thick walls work for self-storage. The reinforced floor works for theatrical props. The even natural light works for boat restoration. The office at the front works for an accountancy practice. The building has, almost incidentally, turned out to be useful for things its designers could not have anticipated.
This is, the current owner tells me, the reason the building still exists. A similar warehouse a hundred yards down the road was demolished in 2003 because it had, by then, become uneconomic to maintain. The building I am standing in did not, by his account, become uneconomic. It found tenants who wanted what it offered, and the rent has, in the past two decades, just about covered what the building needs spending on it.
What happens next
The owner is sixty-seven. He has, he tells me, no specific plans for what will happen to the building when he retires. His children are not interested in the building. He has had one approach, in the past five years, from a developer interested in converting the building into flats. He has not, so far, engaged with the approach. The building, he says, is doing useful work for several tenants and providing him with a modest income. Conversion would change all of that. He is not, on the whole, in favour.
I left the building with a strong sense that I had seen something fairly unusual: a piece of industrial architecture that has, by a slow process of adaptation, become quietly indispensable to a small number of working tenants in a small coastal town. The building is not, by any measure, a heritage site. It will not be listed. It will not be photographed by Historic England. It is, however, still doing the work, in a modest and slightly improvised way, and the work would be considerably harder to do without it.
