Usually, the concept of sufficient stability of a floating structure is connected with the capacity to keep a small heel angle despite the moment of heeling. The variable responsible for these characteristics is the initial metacentric height, which is the relation between the hydrostatic features of the pontoon and the mass properties of the entire object. This article answers the questions of how heavy the floating system should be, what the minimum acceptable draft is, and whether it is beneficial to use internal fixed ballast. To cover various technologies, a theoretical model of a cuboid float with average density representing different construction materials was analysed. The results indicate that the common practice of using heavy and deep floating systems is not always reasonable. In the case of floating buildings, which, unlike ships, can be exploited only under small heel angles, the shape and width of the submerged part of the object may influence the stability more than the weight or draft.

The paper presents results from social research on the Polish business representatives potentially interested in using the floating buildings. The main purposes of the study were to assess the level of knowledge about floating buildings and diagnose stimulants and inhibitors of their development in the hotel, catering, and water tourism industry. Combining the quantitative and the qualitative methodology, research was conducted using an on-line survey (CAWI) and Focused Group Interviews (FGI). Both involved a non-probabilistic, purposive sampling to reach a specific subgroup of the industry: owners or employees of catering, hotel or water tourism companies having or considering having a floating building. The group included both new and long-standing companies using facilities on water or with direct and indirect access to the water. The study identified stimulating and inhibitory factors broken down into internal (context-independent) and external (context-dependent) conditions. Results show that in Poland floating commercial buildings are a niche topic but also a developable one. Although 71% of the respondents notice difficulties resulting from the insufficient infrastructure and 66.5% of them indicate the lack of legal regulations, they also see the potential of floating buildings: depending on the industry, from 90 to 95% respondents find them “definitely attractive” or “rather attractive”. The most common reason for rejecting floating development is the lack of attractive moorages in the area (43.5% answers).

The paper presents an example of the world’s largest design floating housing community – Waterbuurt, formed at the water within the limits of Amsterdam in the Netherlands. Construction on water undertakes a number of engineering, planning and legal challenges, influencing the new aesthetic as well as economic value of the investment.

Przedstawiono przykład największego na świecie zaprojektowanego osiedla zabudowy na wodzie – Waterbuurt powstającego na wodnym kwartale, stworzonym w granicach Amsterdamu w Holandii. Budownictwo nawodne podejmuje szereg inżynieryjnych, planistycznych oraz prawnych wyzwań, wpływając na nową estetyczną, jak też ekonomiczną wartość inwestycji.
