Interior designer Veneta Nikolova and architect Dimitar Karanikolov have transformed an attic in Sofia, Bulgaria into an amazing apartment. The two-year Loft 9b project yielded amazingly clever results. For starters, there’s a large dark cube that conceals the bathroom that sits on top of the building’s elevator shaft. The cube’s walls are just 16mm thin, with custom made concrete panels on the inside. Due to privacy concerns, the entire apartment is outlined with tall cantilevered aluminum planters, which also does double duty to create a soothing and lush green courtyard. The upstairs bedroom has a bathtub in the middle of the room, which sounds great to us when we can’t manage to stagger our way to the shower. Other highlights include black metal panels around the ventilation system, a wooden drawer concealing the air conditioner, and magnet-held Edison bulbs above the dining table.
