Original story here:
In 1996, Barcelona architects Eva Prats and Ricardo Flores were hired to convert an old community laundry into a penthouse. At just 27 square meters (290 square feet), the space was minimal; it was also just a temporary home and the clients wanted a home that was maintenance-free.
Prats and Flores (in collaboration with the Mallorcan architectural firm Duch-Pizà) delivered their solution in the form of two suitcases. Their “Casa en una Maleta” (House in a Suitcase) consists of two big trunks in the center of the room which can be opened throughout the day to satisfy daily living needs.
