The construction system using so-called flat-packs is used quite frequently; however, delivering buildings made up of large-format modules flat- packed is rather unique. The cultural centre in Rybník, Czech Republic, with an area of 324 sq. meters, consists of 10 large-format Comfort modules, and the vertical clearance of the hall, comprised of 6 modules, must have a clear height of 4.3 meters. The centre’s facilities, i.e. a kitchenette, restrooms, storage rooms and a clubroom, were built from 4 standard modules with a clear height of 2.8 meters.
