This custom-made city retreat is almost invisible from the street & is nestled on a quiet cul-de-sac of sun-soaked Potrero Hill. Tucked behind a private fence, the Japanese inspired home is approached through a rock garden with Japanese maple trees and large stepping stones. Upon entry you are greeted with an open, airy design that mixes modern materials like-integrally-colored cinder block, glass and steel with natural wood. The floor-to ceiling windows and doors have removeable shoji screens. The main level features an open floor plan concept, sunlit kitchen, full bathroom & direct access to the serene backyard with a bubbling pond, bamboo garden and spectacular cherry blossom tree. The lower level of the home has an industrial-style feel with concrete floors, exposed ceilings and the continued cinder block walls. Perfect for a primary suite, this level currently has a half bathroom with the potential to add a spacious spa-like bathroom, & has direct access to the front and backyard.
