Complete sustainable refurbishment of an apartment in Barceloneta. To make a maximum profit of the space (25 m2), the concept was to concentrate storage space, and let the apartment as spacious as possible, maintaining the soul of the original character of this apartment, using only sustainable materials. The floorplan is an open kitchen/bar, which at the same time is the dining space, the closets are hiding all the equipment, around the bed is the wardrobe for clothing. The small but functional bathroom has a shower, and there is a bath in the bedroom with views at the sea. To maintain the original character, the hydraulic floor tiles were polished in combination with a wooden floor. Finishing of all walls in bathrooms and kitchen is eco wax, this smooth surface without joints in combination with the white and light blue painted walls give the apartment a spacious feeling.
