Alison & Peter Smithson

It all began with a letter in May 1984, signed by a tom-cat in Bad Karlshafen, addressed to another tom-cat in London. In the letter, the cat known as Sir Karl, writing on behalf of his butler Axel Bruch- ha¨user, commissioned Snuff - the cat belonging to architects Alison & Peter Smithson - to construct two lookouts for his ''Hexenhaus''. The letter marked the start of a fateful collaboration between Axel Bruch- ha¨user and the architects, the prelude to permanent alterations to the Hexenhaus - itself a poetic construct of lattices and built-fabrics. Step by step, the house was expanded and opened to admit the light as well the trees, which became part of the interior. The Hexenhaus is a testament to the early, radical style of the Smithsons, to the corrective and anti-aesthetic character of their finest designs - and at the same time, a monument to the professional work of Alison & Peter Smithson.
