What is the name of the De Stijl icon designed by Gerrit Rietveld in Utrecht?

The De Stijl icon designed by Gerrit Rietveld in Utrecht is the Rietveld Schröder House.

Built in 1924, the house was commissioned by Truus Schröder-Schräder, who worked closely with Rietveld on its design. Located at Prins Hendriklaan 50, it rejects the enclosed, symmetrical appearance of conventional houses through intersecting planes, strong horizontal and vertical lines, and carefully composed colors associated with De Stijl, including red, blue, and yellow.

Its most radical feature is the upper floor. Instead of a fixed arrangement of rooms, sliding and revolving panels allow the space to shift between an open family area and separate rooms. Windows are hinged so they open at right angles, reinforcing the house’s abstract geometry and blurring the boundary between inside and outside. The building was constructed mainly from brick and plaster rather than concrete, which Rietveld had initially considered.

The house is also called Schröder House, so that shorter name is a defensible variant, but the stored answer is the standard full English name. Truus Schröder lived there until her death in 1985. It became a UNESCO World Heritage Site in 2000 and is now preserved as a museum.
