Hidden House by Standard Architecture is located on a serene 7-acre site in the Mount Washington area of Los Angeles. It’s a great example of open to outdoors house. It features two courtyards. The living space opens up to one of them, while the second one looks out over the city. The 3500 square feet home is made of sustainable materials including the redwood cladding, reclaimed endgrain block wood and the cork flooring in some rooms. Besides it also features some other “green” features. Its design allows excellent cross ventilation and day lighting, reducing the need to run forced-air conditioning or heat or energy-consuming electrical lighting. The house is solar-ready and appliances around it are highly efficient. The garden is planted with native landscape and vegetables.
