Designed by award-winning architect ... Carsten Jensen as a prototype for high performance sustainable houses, this leading-edge environmental home has achieved an EnerGuide rating of 87 - the highest reported in the area to date. The superinsulated shell creates a superior level of comfort with an almost constant base temperature and excellent sound insulation. Solar collectors (photovoltaic and thermal), rainwater harvesting and a green roof are additional environmental features. Conceived as a play of cubes, the assertively modern exterior of the house is softened by a cedar entrance and planted trellises. The rich but restrained interior foregrounds natural materials and is enhanced by a constantly changing play of natural light. The house features superior finishes throughout. The interior presents a harmonious material palette with Eastern maple floors, fir doors and deep wood window casings. An eleven foot ceiling in the great room lends emphasis to the contemporary gas fireplace in a dramatic south-facing window wall. The designer kitchen showcases Silestone countertops, European appliances and an Italian ceramic tile floor. There is a private deck on the upper level adjacent to the green roof and a generous south-facing deck in the fenced backyard. Professional landscaping complements and enhances the architecture. Featured in the 2010 Oceanside Home and Garden Tour and extensively published, this is a special house for a discerning purchaser. MLS# 323441.
