The aim of the project is to develop an innovative modular hotel vessel. The assumptions are to develop 3 prototypes of hotels floating depending on river conditions. The project is a response to the growing demand for attractive and unusual hotel spaces in city centres. The project will be implemented by 24 m from 09.2018 to 08.2020 and covers 4 stages. Industrial research (stage 1 and 2) concerns the development of the construction and construction of prototype vessels together with the development of a system of basic functionalities for intelligent building management. It is also planned to develop a low-energy building so that energy demand is minimal. The challenge is to develop modularity of the structure, which will allow for small immersion of the object and the possibility of multiple assembly and disassembly. Thanks to the above functionality, it will be possible to broaden the range of possible locations for hotel units, practically on every river basin and thus open the hotel market to unprecedented solutions. Stages 3 and 4 concern the verification of the developed construction technology during real-world tests. These steps will allow for the improvement of prototypes and the final confirmation of achieving the established design assumptions. The results of the research will be the basis for the use of the resulting results in the company’s own business activity. Newly developed structures, which constitute an innovation on a national scale at least, will be included in the offer of the Applicant and will be manufactured in Poland.
