A Prefabricated Marvel in the English Countryside

Architectural Flexibility in Action with the Koto Haku

The newly completed units at the Denton Estate in Yorkshire exemplify the structure’s versatility. Configured as luxurious hotel suites featuring wood-burning stoves and rain-shower bathrooms, these units make the most of a unique loophole in UK planning law. Classified legally as caravans, thanks to their wheeled chassis, the cabins bypass typical location restrictions, allowing placement in previously inaccessible areas.

The Freedom of Mobile Living

Measuring 9.74 meters in length, 3.60 meters in width, and 3.85 meters in height, the mobile cabin requires no permanent foundation. Its installation and removal leave the landscape unmarked, enhancing its appeal for eco-conscious users. Each cabin boasts a timber frame with an organic facade crafted from expanded cork, providing a sustainable yet chic finish. Koto offers full furnishing options, enabling quick deployment as a turnkey hospitality solution.
