Application of multi-criteria method to assess the usefulness of a hydrotechnical object for floating housing

Abstract

This publication presents the analysis of three hydrotechnical objects located in the Municipality of Gdańsk with a view of mooring Floating Houses. The assessment of the adaptation of a hydrotechnical object has been carried out by a multi-criteria method AHP and using the main criteria such as: mooring system, communication with the mainland, availability of the utility networks, waste disposal and location of the parking spaces. The analysis allowed to conclude that there are no hydrotechnical objects in Gdańsk, which would be fully adapted to mooring of Floating Houses without additional infrastructure investments. The most adapted site out of the three ones considered in the Municipality of Gdańsk is location no. 1 – the Rybackie Pobrzeże.

Proposed concept for the development of residential floating facilities

“…Development strategies should include solutions to formal and legal [1][2][3][4][5][6][7][8][9], technical [5,[10][11][12][13][14], economic [1-3, 5, 7-8], environmental [15][16][17][18][19][20][21][22][23][24], demographic and socio-cultural [2,[25][26] issues.…”

Enviromental factors as the elements determing the development of floating homes

“…Nevertheless, more and more frequently residential floating structures can be observed in Polish towns (Figure 4). Therefore, an increasing number of Polish researchers are concerned with the subject of floating structures, as evidenced by publications [10,13,14,[19][20][21][22][23][24][25][26][27][28] The positive and negative environmental impact of FH are both still unspecified and additional research is essential in this area. The identified knowledge gap causes certain difficulties to various decision makers (including the decision makers dealing with water areas) and municipalities in creating a framework for spatial policy and regulating as well as facilitating the development of new projects connected with FH [5][6][7].…”

The Selection of Anchoring System for Floating Houses by Means of AHP Method

“…The Netherlands is the exception because the popularity of floating houses increased in manner forced by nature. Around 50% of the area of the Netherlands is located below sea level [3][4][5]. The consequence of the greenhouse effect is climate change, which causes the sea level to rise and storms to become more violent.…”

“…The consequence of the greenhouse effect is climate change, which causes the sea level to rise and storms to become more violent. Therefore, in the Netherlands it has been decided not to fight with the sea, but to use its strength and adjust to it [5]. A necessity soon turned into a lifestyle, fashion, a symbol and synonym of freedom, luxury, and a comfortable life.…”

“…The first floating house was located in Wrocław in 2010. Since then, many changes have taken place and the awareness of the society has been raised enough for floating houses to be accepted and generate interest of growing group of people [5,6]. The consequence of the phenomenon is the dynamic market development and substantial growth in the number of producers offering floating houses, which are ready to move into or designed according to the needs and indications of an investor.…”
