The GZDG is an architecture studio in Rome, specialized in semisubmerged architectural structures, marine parks, floating habitats and yacht design. It was founded in 2001 by the architect Giancarlo Zema as a dynamic and flexible organization, which guarantees the whole design process, from the concept to the executive details. We use advanced technologies and design software, which allow us to project and calculate different planning solutions. With the use of computer-aided design systems, we can realise 3D models, prospective views and renderings, by means of full layout presentation. This offers the client all the necessary information
