Lonely Planet review
This Unesco-recognised landmark house is just outside the city centre. Built in 1924 by Utrecht architect Gerrit Rietveld, it is a stark example of ‘form follows function’. Only six colours are used: red, blue, yellow, white, grey and black. Visits are by mandatory tour, which should be booked in advance at the Centraal Museum (see website for details); the museum will give you a map for the pleasant 25-minute stroll to the house or loan you a free bike.
