The Blue House was designed by the Dutch architect Pieter Weijnen from FARO Architecten. It is located in Steigereiland, one of seven man-made islands that were dredged from Lake IJ in Amsterdam in IJburg. Its color is reminiscent of the deep blue water that surrounds it, and that’s how it gets its name. The house was designed with sustainable energy use in mind. The large south facade lets in a lot of light and warmth. The cooling system is inspired by old Arabic cooling towers. Air from the house is pumped into an underground pipe from which the cooled air is returned to the house. Rainwater is reused for the toilet and washing machine. The building is made of wood and recycled materials. The beams in the facade are old bollards from Lake IJ. The copper plates in the hanging living room come from a church roof.
