These old offices were not very big. That is why they had to make the most of every space in their workplace.
With Kewlox furniture, they optimise the storage capacity in each room because, thanks their sliding door system, these cabinets only use the space that is strictly necessary.
In practice they created cabinets which fitted their dimensions with doors, sides, black and shelves made of natural MDF.
A solid wooden frame and galvanised angle brackets gave them the solidity robustness needed for heavy storage.
