Sustainability is a concept that has been crucial in informing all components of the design, construction and daily use of the house. All living spaces receive daylight from more than one direction. Storage units, bathrooms and other ancillary spaces also receive daylight, some of it indirect. All artificial lighting is LED-based. Much of the furniture is built-in and where possible made of sustainable materials likeĀ  bamboo for the floors and wardrobes. via
