House located in Utrecht, considered one of the symbols of modern architecture. Designed by Dutch architect Great Rietveld in 1924. It is the only de Stijl style building that is characterized by the use of primary colors and abstract shapes. The horizontal plan of the house is almost devoid of any fixed internal wall, and the outside is linked to the inside through large glass windows, and the same colors that Mondrian used in his paintings were used. The horizontal and vertical elements of the building are also stressed. Since 2000 the house has entered the list of UNESCO World Heritage Sites.
