The Mini-Maison (tiny house) is one of the many old small workers houses built in Forest, one of the 19 communes (districts) of Bruxelles, Belgium.

Transforming the modest house (each floor is only 245 square feet) into a contemporary house for a couple with no kids was a big challenge for Brussels-based architecture firm Vanden Eeckhoudt-Creyf Architectes.

The original staircase was replaced by a flight of stairs built into the wall and a fireman’s pole was installed for quick descent.

Finally, a fourth floor sleeping loft was added to increase the living space of the house.
