Architects Beatriz Ramo and Bernd Upmeyer have designed an ultra-compact living space in the heart of Rotterdam, measuring just 6.89 square meters.

This project is a collaboration between their two architecture firms—STAR strategies + architecture, founded by Beatriz Ramo, and BOARD Bureau of Architecture Research and Design, led by Bernd Upmeyer.

Located on the top floor of a 1950s modernist building, the apartment is called “Cabanon,” inspired by the tiny cabin designed by French architect Le Corbusier.

The space is divided into four distinct areas, each with its own materials, colors, and ceiling heights: a 3-meter-high, ochre-toned living area

A standout feature of the living room is a wall divided into 12 “cubes” that open like an advent calendar. These compartments hold a foldable table, a small sink, a refrigerator, and shelves for books.

The apartment doesn’t have a full kitchen, but the architects say the neighborhood’s numerous restaurants make it unnecessary.

According to the designers, the creative layout and thoughtful zoning make the space feel open and airy despite its limited size.

The project cost approximately $23,000, excluding the time spent on design work.
