Casa Gialla is a renovation project just completed by gon architects in Madrid, Spain. The new 505-square-foot apartment was once a dark attic in a building in the center of Puerta del Sol. Now, the multifunctional apartment houses hidden rooms, a Murphy bed, lots of storage, and an outdoor shower and bath, all coming together as an oasis in the city.

The homeowner, an Italian woman who loves design, technology, and the good life, asked for two things of the new design ? it must be pragmatic and enjoyable. To make that happen, partition walls and wooden beams were removed to reveal an open and bright rectangular space.

The main living space’s most notable feature is the wall of mustard yellow shelving and storage. On the opposite wall is a minimalist kitchen made up of only lower white cabinets and built-in appliances. The kitchen counter sinks down on the left side to become a desk for the home office. By lining the walls with the necessities, it frees up the center to be other things, including a small dining area.
At one end of the apartment is a southwest facing terrace that includes more than just seating and plants ? there’s also an outdoor shower and hidden bathtub.

Hidden behind the yellow storage wall is a passageway to the bedroom and a bathroom.

There’s an opening in the cabinetry between the bedroom and living space that houses a pop-down projector. There’s also a matching curtain that can offer privacy when needed.

A two-s...
