MOCO Concept Store is a retail interior project located in Barcelona, conceived as an immersive architectural environment. The space is defined by a continuous monochromatic envelope executed in microcement, integrating walls, floors and bespoke furniture into a single spatial system. Organic geometries, rounded openings and recessed niches organize circulation, display and lighting. The construction required custom fabrication, precise execution of curved surfaces and seamless junctions between materials to achieve a unified and highly controlled interior suitable for art and collectible objects.
