Architecturally graphic yet light and airy, Petra revamps whole-home storage to suit your space and wow your walls. A vision in black, the cabinet and bookcases are made of ebonized solid oak and oak veneer and iron tubing that's finished with a blackened acid patina. The minimalist cabinet floats between the two wide bookcases anchored to the wall and bridging two offset shelves between them. Open and closed storage abounds with 14 open shelves, a drawer and cabinet space. Linear and minimalist, Petra updates mid-century wall systems for a look that's distinctly contemporary and truly room-transforming.
