The models in this section range from musea and cinema complexes to community based constructions. A museum is usually a specialized construction ranging often from the conversion of an existing (historical) building to purpose designed structure. Cinemas follow trends so multi-screen complexes with as many 10 screens are not uncommon and throughout Europe large corporations operate in several countries providing a set format and house style. Such are the numbers of these projects internationally that there are good cost models available. Other structures are one off community facilities like community centers with unsophisticated designs to conference centers which may be part of other facilities like hotels.
