Why floating homes are popular in the Netherlands
The Netherlands is experiencing an increase in interest in floating homes as a result of rising floods and a housing crisis. More ambitious Dutch-led projects in flood-prone countries, such as the Maldives and French Polynesia, are being influenced by these floating villages.
Residents of Amsterdam's Schoonschip floating neighborhood were confident they could weather a severe storm in October 2022. As their community slid up and down its steel structural pillars, rising with the water and falling back to its original position after the rain stopped, they secured their bikes and outdoor seats, checked in with their neighbors to make sure everyone had enough food and water, and hunkered down.
According to Siti Boelen, a Dutch television producer who came to Schoonschip two years ago, "we feel safer in a storm since we are floating." "I find it really odd that construction on water is not a global priority."
Floating neighborhoods provide an experiment in flood defense that could help coastal cities better endure climate change as sea levels rise and supercharged storms cause seas to swell. The demand for these homes is rising in the Netherlands, a country with limited land but a dense population. Additionally, authorities are trying to amend zoning regulations to facilitate the building of floating homes as more people seek to erect buildings on the water there.
"The municipality wants to develop the concept of floating because it is multipurpose use of space for dwelling, and since the sustainable approach is the way forward," says GreenLeft Amsterdam city councilor Nienke van Renssen.
In the last ten years, the Netherlands' floating settlements have developed as proof of concept for larger-scale initiatives that are currently being led by Dutch engineers. These include not only European nations like Britain, France, and Norway, but also French Polynesia and the Maldives, an Indian Ocean nation where sea level rise is currently posing an existential threat. Even the idea of building little communities on floating islands in the Baltic Sea has been proposed.
We are used to living on water, says Marjan de Blok
Any beachfront can be used to build a floating home, which can withstand flooding caused by rain or rising sea levels by staying above the water's surface. Floating homes are fixed to the shore, frequently resting on steel poles, and are typically connected to the local power grid and sewer system, in contrast to houseboats, which are readily detached and moved. In order to stay stable in the water, they have a concrete hull that serves as a counterbalance in place of a basement, which makes them structurally comparable to homes constructed on land. Prefabricated, square-shaped, three-story townhouses made off-site from standard materials like steel, glass, and wood are common in the Netherlands. Floating dwellings are one possible model to increase urban housing in the era of climate change for cities dealing with increasing floods and a lack of available land.

According to Koen Olthuis, who established Waterstudio, a Dutch design business that specializes only in floating structures, in 2003, the main benefit of floating homes may be their low-tech character. In order to lessen the sense of movement caused by adjacent waves, the dwellings he builds are equipped with shock-absorbent materials and stabilized by poles that are excavated around 65 meters (210 feet) into the ground. When the water level rises, the houses rise, and when it falls, they fall. However, Olthuis argues that despite their seeming simplicity, they have the capacity to change cities in ways not seen since the invention of the elevator, which raised skylines.
Olthuis, who has created 300 floating residences, workplaces, educational institutions, and medical facilities, claims that "we now have the technology, the possibility to build on water." He went on to say that he and his associates "view water as a medicine and do not consider ourselves as architects, but as city doctors."
In the Netherlands, where a third of the country is still below sea level and the majority of the country is constructed on reclaimed ground, the idea is not entirely implausible. Hundreds of people have relocated into floating homes in once abandoned neighborhoods in Amsterdam, which has around 3,000 legally registered traditional houseboats among its canals.

Koen Olthuis Rotterdam, 90% below sea level and the location of Europe's largest port, is home to the world's largest floating office building and a floating farm where robots milk cows to provide dairy products to nearby grocery stores, so the notion of a crazy magician creating a floating house is no longer relevant. Rotterdam has been stepping up efforts to mainstream similar projects since the 2010 opening of the Floating Pavilion, a solar-powered meeting and event venue in the harbor. The city has named floating buildings as one of the cornerstones of its Climate Proof and Adaptation Strategy.We have reimagined ourselves as a delta city for the past 15 years," says Arnoud Molenaar, the City of Rotterdam's chief resilience officer. "We view water as an opportunity rather than merely an enemy."
The Dutch government launched the "Room for the River" program in 2006 to help protect cities from climate change. This program aims to embrace rising water levels rather than fight them by purposefully allowing some regions to flood during times of heavy rain. According to Olthuis, the Netherlands' housing scarcity may increase demand for floating homes, particularly in "Room for the River" neighborhoods where flooding is expected to occur, at least for a portion of the year. According to experts, building one million additional homes over the next ten years will be necessary to alleviate the housing deficit in the Netherlands. The lack of land for development may be lessened with the use of floating homes.
Developers from outside have started requesting more ambitious projects from Dutch enterprises that specialize in floating buildings. A projected network of floating islands in the Baltic Sea is presently being developed by Blue21, a Dutch tech company that specializes in floating buildings. A privately funded €15 billion ($16.9 billion/£12.5 billion) underwater train tunnel connecting Helsinki, Finland, and Tallin, Estonia, could be connected to the complex, which could house 50,000 people. Peter Vesterbacka, a Finnish investor and "Angry Birds" entrepreneur, is supporting the project.
This winter, Waterstudio will supervise the construction of a floating home development close to Male, the Maldives' low-lying capital, where 80% of the nation is below 1 meter (3 feet) above sea level. It is made up of reasonably priced, plainly constructed homes for 20,000 people. Artificial reefs will be built beneath the hulls to aid in the sustenance of marine life. Cold seawater from the deep will be pumped into the buildings to support air conditioning systems.The notion of an insane magician creating a flying home has vanished, according to Olthuis. "Now we're creating blue cities, seeing water as a tool."
