Behind a striking steel and glass facade lies a one-of-a-kind architectural residence on Potrero Hill's coveted north slope. Built in 2006, this custom four-level home blends bold design with refined luxury and seamless indoor-outdoor living. A sunlit courtyard entry sets the tonelush and tranquil, it flows effortlessly into the main living area through dramatic pivoting glass doors. The open floor plan features a chef's kitchen with dual refrigerator/freezers, wine fridge, sleek range, custom island, and integrated dining table. A built-in media center, gas fireplace, and flexible entertaining areas make this the ultimate modern gathering space. The extraordinary primary suite opens to a private terrace with sweeping skyline views. Its spa-like bath offers a jacuzzi tub, walk-in shower, and serene palette. An executive office with custom metal shelving and a wall of windows supports a stylish work-from-home lifestyle. On the lower level, a private patio invites outdoor movie nights or serene garden moments and connects to a detached guest suite with ensuite bath and sliding glass doors. With Venetian plaster walls, radiant floor heating, a two-car garage, and thoughtful details throughout, this home is a rare example of contemporary elegance and architectural ingenuity.
