The Cabanon is a fully equipped apartment of 6.89m² including an infrared sauna and a whirlpool bath. It hosts four rooms and it is most likely the smallest apartment in the world; certainly the smallest with a spa.

The inside dimensions of the Cabanon are H: 3 m, W: 1,97m, L: 3,6m. It has a 6m² window overlooking the city. It is organized into four spaces extravagantly different in materials and heights: a 3m-high living room with kitchen, a 1.14m-high bedroom with plenty of storage, a toilet with a rain-shower, and a spa.

The Cabanon makes clear that different rooms with different sizes and functions might not need the same height. The Cabanon seemed to get bigger the more programs were added to it. The adaptation of heights made that possible.

The Cabanon is the conversion of an existing attic used for storage into a living space. It is located on the top floor of a 1950’s residential building in the centre of Rotterdam. The four spaces in the Cabanon have been shaped based on standard products: the bedroom was designed with a specific mattress in mind; the spa according to the bathtub length; the kitchen based on the mini-fridge depth, in order to avoid the need of customized objects, but rather the other way around: the Cabanon would adapt to standard and affordable products.

The Cabanon takes its name from the eponymous cabin of Le Corbusier at the Côte d’Azur. Like the Le Corbusier cabin, the Cabanon of Rotterdam has been conceived by the same architects who will use it. It is 6,89 m², half the size of Le Corbusier’s unit and –unlike his Cabanon– fully autonomous and designed for a couple.

The Cabanon is a temple in the proportions of its owners who became the modulors of their Cabanon. It is an experiment in space for them who increasingly saw personal growth in voluntary reduction. However, this reduction was never understood as austerity. The Cabanon is of the most luxurious smallness, an epicurean reduction.

This project was conceived by STAR and BOARD shortly after completing their large research project in 2012 into the “maximization of space” by sharing, on their project “Co-Residence” for the AIGP (Atelier International du Grand Paris). For the Cabanon, STAR and BOARD, took an opposite path and experimented on reduction.
