Haus Wittgenstein (also known as the Stonborough House and the Wittgenstein House) is a house in the modernist style on the Kundmanngasse, Vienna, Austria. It "shows remarkably similar characteristics in its obsession with detail and complete disregard for the requirements of the people who are expected to live within it." The house was commissioned by Margaret Stonborough-Wittgenstein, who asked the architect Paul Engelmann to design a townhouse for her. Stonborough-Wittgenstein invited her brother, the philosopher Ludwig Wittgenstein, to help with the design. In the end, he became more author than helper.
