For the Cologne architect Oswald Mathias Ungers (1926-2007), owner of a
famous collection of books on architecture, who also repeatedly
addressed the theoretical aspects of building, the construction of his
own house, in 1958/59, was more than a private adventure. For him it
meant a chance to gain spatial experience and explore what was possible.
It was a laboratory, »a little universe«, »a piece of world«. Three
decades later, Ungers expanded the cataract of forms of his first home
by adding a geometrically strict cube, intended to house his library.
The shock aesthetics of the early work had evolved into the rigorous
abstractness of his late work.
