In 1926, Ludwig Wittgenstein took over the interior design of a Modernist townhouse in Vienna for his sister, Margarethe. Retaining the overall structure designed by the architect, Paul Engleman, for two years Wittgenstein focused on the layout, dimensions and interior fittings – windows, doors, door handles and radiators. Haus Wittgenstein comes between the Tractatus (1921/22) and the notes, lectures and posthumous publication of the Philosophical Investigations, a radical re-think of his theory of language. Taking the building as a transitional object, ‘Wittgenstein’s Ruler: Haus Wittgenstein and the Aesthetics of Space’ is a collaboration with Ergin Çavuşoğlu exploring spatial epistemologies through drawings, installations, objects and video.
