The investor wished for an extension to his farmhouse in Southern Bohemia, one that he could rest and relax in – a lookout and an observatory. We extended the volume of one of the wings of the building with a semi-transparent timber structure. In terms of articulation of form, the extension is in complete harmony with the original farmhouse. In terms of structure, however, the transparent timber frame, along with its zen atmosphere, is a complete contrast. The ground floor serves as a storage for firewood. Once through, one can climb up a spiral staircase onto a bridge connecting the old attic with the new. Each of the spaces encloses a single room. The old attic serves as an astronomical observatory, the new as a lookout.
