Recently, Dutch firms have carried their control over the sea one step further, pioneering floating buildings and cities as a solution to rising sea levels. One of them is the developer Dutch Docklands, which describes itself as having ‘learned to live with the water instead of fighting it’. it works closely with the firm of architects Waterstudio, run by awardwinning architect Koen Olthuis.
“The climate change generation is no longer interested in iconic architecture, but are looking for iconic solution,” says Olthuis. “It is not the result of the individual architect that that counts, but the effect on society.” Perhaps their most futuristic work is the Krystall hotel, which will open at the end of 2016. Designed to look like a giant floating snowflake, it is being built in the icy seas near the city TromsØ in Norway. The Hotel will have glass roofs so guests can watch the Northern Lights. Its hallways will be lined with futuristic blue shapes and fireplaces will be converted in transparent blocks to look like ice.
“We call it scarless development. If you take it away after 100 years or so, it will not leave any physical foot-print,” explains Olthuis, who says that Dutch attitude is: where there is nothing, anything is possible. “The Dutch created Holland out of the sea, and that mentality is in our DNA, forcing us to be creative in situation where there seem to be no obvious solution. Some of the innovations that were born of necessity soon show potential for worldwide use.”

From the very first moment of seeing the planned location for this villa Architect Koen Olthuis of Waterstudio set out to design a subtle villa that would allow for the optimal experience of its surroundings.

In order to maintain the rural character of the location, the assignment came with strict regulations limiting the volume allowed above the ground level. These limitation eventually proved to give rise to a rather sophisticated design filled with spatial solutions.

With the volume limited, Waterstudio decided to make a floor under ground level, providing extra surface within the limited dimensions of the building-envelope. Solutions for allowing daylight in the lower floor turned out to be the main architectural highlights.

The volume was taken up as a white frame outlining large surfaces of glass, making the whole villa rather transparent. Some touches of wood add subtlety and warmth to the scheme. The white frame curling along the facade closes off both ends of the house. In the middle the frame rises to mark the entrance.

The concept of transparency was maintained throughout the house by creating an open layout where, almost no doors are used. Typical eye catchers in the interior are the kitchen situated in the center of the house.

Beside the exterior of the Villa, Koen Olthuis designed the interior and the garden what brings the total design of the plot in harmony. In the green sloping garden the water of the New water is literally brought into the plot.

Floating homes may be answer to flooding in Thailand

By Reuters
South China Morning Post
2015.March.13

Nestled among hundreds of identical white and brown two-storey homes crammed in this neighbourhood for factory workers is a house with a trick – one not immediately apparent.

Hidden under the house and its wrap-around porch are steel pontoons filled with styrofoam. These can lift the structure three metres off the ground if Ban Seng village, two hours north of Bangkok, floods as it did in 2011 when two-thirds of the country was inundated, affecting a fifth of its 67 million people.

The 2.8 million baht (HK$667,145) amphibious house is one way architects, developers and governments around the world are brainstorming solutions as climate change brews storms, floods and rising sea levels that threaten communities in low-lying coastal cities.

“We can try to build walls to keep the water out, but that might not be a sustainable permanent solution,” says architect Chuta Sinthuphan of Site-Specific, the firm that designed and built the house for Thailand’s National Housing Authority (NHA).

“It’s better not to fight nature, but to work with nature, and amphibious architecture is one answer, says Chuta, who is organising the first international conference on amphibious architecture in the Thai capital in late August.

In Thailand, as across the region, more and more construction projects are returning to using traditional structures to deal with floods, such as stilts and buildings on barges or rafts. The amphibious house, built over a man-made hole that can be flooded, was completed and tested in September 2013. The home rose 85cm as the dugout space under the house was filled with water.

In August, construction is set to begin on another flood-resistant project – a three million baht floating one-storey house on a lake near Bangkok’s main international airport.

“Maybe in the future there might be even more flooding … and we would need to have permanent housing like this,” says Thepa Chansiri, director of the NHA’s department of research and development.

The 1,000 square foot floating house will be anchored to the lake’s shore, complete with electricity and flexible-pipe plumbing.

Like the amphibious house, the floating house is an experiment for the NHA to understand what construction materials work best and how fast such housing could be built in the event of floods.

The projects in Thailand are a throwback to an era when Bangkok was known as the Venice of the East, with canals that crisscrossed the city serving as key transport routes.

“One of the best projects I’ve seen to cope with climate-related disasters is Bangkok in 1850. The city was 90 per cent on water – living on barges on water,” says Koen Olthuis, founder of Dutch architecture and urban planning firm Waterstudio.

“There was no flood risk, there was no damage. The water came, the houses moved up and down.”

Olthuis started Waterstudio in 2003 because he was frustrated that the Dutch were building on land in a flood-prone country surrounded by water, while people who lived in houseboats on the water in Amsterdam “never had to worry about flooding”.

His firm now trains people from around the world in techniques they can adapt for their countries. It balances high-end projects in Dubai and the Maldives with work in slums in countries such as Bangladesh, Uganda and Indonesia.

One common solution for vulnerable communities has been to relocate them to higher ground outside urban areas – but many people work in the city and do not want to move. Olthuis says the solution is to expand cities onto the water.

Waterstudio has designed a shipping container that floats on a simple frame containing 15,000 plastic bottles. Waterstudio’s aim is to test these containers in Bangladesh slums, giving communities flood-safe floating public structures.

A couple years back, Disney used the space-age material Corian to build a real-life version of the futuristic house from the 1980s movie Tron. Now a firm in the Netherlands has clad a submarine-shaped home next to a lake with the material, for a very high-tech effect. Indeed, the one-story home with floor-to-ceiling windows by Waterstudio.NL has the rounded edges and elegant white shell of a living space created by Apple engineers.

Building in the rural location of Westland, Holland comes with rules about the permitted heights for structures. The resulting Corian-and-timber house is low to the ground, with a main entrance on the side of the volume, and a subterranean level that is obscured from the lake-side. “The concept of transparency was maintained throughout the house by creating an open layout where almost no doors are used,” architect Koen Olthuis writes.

Villa New Water by Waterstudio.NL

Koen Olthuis of Waterstudio.NL has designed Villa New Water, a waterfront home for a family in Westland, The Netherlands.

The description from Waterstudio.NL

From the very first moment of seeing the location for this villa, Koen Olthuis, architect and founder of Waterstudio.NL, set out to design a subtle villa that would complement its surroundings and enhance the experience of its surroundings.

In order to maintain the rural character of the location, in the project the New Water, the assignment came with strict regulations which limited the volume allowed above the ground level. These limitations eventually proved to give rise to a rather sophisticated design filled with spatial solutions.

With the volume being limited, Waterstudio decided to make a floor under the ground level, providing extra surface within the limited dimensions of the building envelope. Solutions for allowing daylight into the lower floor turned out to be major architectural highlights.

The volume was taken up as a white frame outlining large surfaces of glass making the whole villa rather transparent. Touches of wood here and there add subtlety and warmth to the overall scheme. The white frame, curling along the façade, closes off both ends of the house by framing different views of the outside. In the center, the same frame rises to mark the entrance. The entrance is designed to be a space to take in the morning sun. The façade alternates between materials like Corian and glass. A flawless material like Corian helps in realizing the strong and seamless building form as envisioned by the architect while glass helps by imparting transparency to the façade.

Besides the physical form of the villa, Koen Olthuis also designed its interior and garden. This brings together the different aspects of the design to harmonize with each other. At the site of the villa, one is welcomed by a few hills. These hills help in scripting the perfect approach for the house. As one approaches the hill, the house which is tucked away behind the hills, slowly comes into full view. The hill also serves as a natural route for the cars arriving at the house. On the other side of the water, a boathouse and a bar take shelter underneath the hill. A good view of the house can be enjoyed from the bar.

By keeping the garden green and simple, and bringing the outside water into it, the garden seamlessly blends with its surroundings. This seamless blend makes the entire area appear like one large garden from the house. To blend the green further with the house, an artificial strip of grass was used at the edge of the house. This would merge with the garden to give an appearance of the house floating over a green garden.

For the building, the guiding concept for design was transparency. Transparency was maintained throughout the house by creating an open layout where almost no doors were used. From the main entrance, one steps into an open hallway and is guided to the left or right by the round edges of the house. The ground floor contains a living room, kitchen and a dining room. The kitchen, located at the centre of plan in the ground floor, is surely the eye-catching design of the house. The long glass walls on the ground floor merges the outside and inside imparting a transparent feeling to the building.

The underground level contains the private functions for the family like a master bedroom, kids’ bedrooms, the wellness area and the lounge. The master bedroom with an open floor plan connects to a hidden inner garden at one end of the building. The inner garden with gravel and bamboo trees can be experienced across the wellness area from the bedroom. The lounge is situated at the centre of the underground level and becomes part of the circulation area. Though this level is completely underground and covered from outside, one does not feel so from the inside.

The furniture in the house was also designed by Koen Olthuis. Using round corners and soft materials, the furniture is in contrast to the hard Corian used elsewhere. A good example of this is the cupboard with a fireplace that divides the living area and the kitchen. Another piece of furniture is the 10-person oval shaped dining table which is closed at the ends thus not allowing people to sit at the head of the table.

In this way, the concepts of transparency and seamless flow have been translated across the different scales of landscape, architecture and interior design.

Thailand tests floating homes in region grappling with floods

AYUTTHAYA, Thailand (Thomson Reuters Foundation) – Nestled among hundreds of identical white and brown two-storey homes crammed in this neighborhood for factory workers is a house with a trick – one not immediately apparent from its green-painted drywall and grey shade panels.

Hidden under the house and its wraparound porch are steel pontoons filled with Styrofoam. These can lift the structure three meters off the ground if this area, two hours north of Bangkok, floods as it did in 2011 when two-thirds of the country was inundated, affecting a fifth of its 67 million people.

The 2.8 million baht ($86,000) amphibious house in Ban Sang village is one way architects, developers and governments around the world are brainstorming solutions as climate change brews storms, floods and rising sea levels that threaten communities in low-lying coastal cities.

“We can try to build walls to keep the water out, but that might not be a sustainable permanent solution,” said architect Chuta Sinthuphan of Site-Specific Co. Ltd, the firm that designed and built the house for Thailand’s National Housing Authority.

“It’s better not to fight nature, but to work with nature, and amphibious architecture is one answer,” said Chuta, who is organizing the first international conference on amphibious architecture in Bangkok in late August.

Asia is the region most affected by disasters, with 714,000 deaths from natural disasters between 2004 and 2013 – more than triple the previous decade – and economic losses topping $560 billion, according to the United Nations.

Some 2.1 billion people live in the region’s fast-growing cities and towns, and many of these urban areas are located in vulnerable low-lying coastal areas and river deltas, with the poorest and most marginalized communities often waterlogged year-round.

For Thailand, which endures annual floods during its monsoon season, the worsening flood risks became clear in 2011 as panicked Bangkok residents rushed to sandbag and build retaining walls to keep their homes from flooding.

Vast parts of the capital – which is normally protected from the seasonal floods – were hit, as were factories at enormous industrial estates in nearby provinces such as Ayutthaya. Damage and losses reached $50 billion, according to the World Bank.

And the situation is worsening. A 2013 World Bank-OECD study forecast average global flood losses multiplying from $6 billion per year in 2005 to $52 billion a year by 2050.

FLOATING HOUSE

In Thailand, as across the region, more and more construction projects are returning to using traditional structures to deal with floods, such as stilts and buildings on barges or rafts.

Bangkok is now taking bids for the construction of a 300-bed hospital for the elderly that will be built four meters above the ground, supported by a structure set on flood-prone land near shrimp and sea-salt farms in the city’s southernmost district on the Gulf of Thailand, said Supachai Tantikom, an advisor to the governor.

For Thailand’s National Housing Authority (NHA) – a state enterprise that focuses on low-income housing – the 2011 floods reshaped the agency’s goals, and led to experiments in coping with more extreme weather.

The amphibious house, built over a manmade hole that can be flooded, was completed and tested in September 2013. The home rose 85 cm (2.8 feet) as the large dugout space under the house was filled with water.

In August, construction is set to begin on another flood-resistant project – a 3 million baht ($93,000) floating one-storey house on a lake near Bangkok’s main international airport.

“Right now we’re testing this in order to understand the parameters. Who knows? Maybe in the future there might be even more flooding… and we would need to have permanent housing like this,” said Thepa Chansiri, director of the NHA’s department of research and development.

The 100 square meter (1,000 square foot) floating house will be anchored to the lakeshore, complete with electricity and flexible-pipe plumbing.

Like the amphibious house, the floating house is an experiment for the NHA to understand what construction materials work best and how fast such housing could be built in the event of floods and displacement.

FLOATING CITIES?

The projects in Thailand are a throwback to an era when Bangkok was known as the Venice of the East, with canals that crisscrossed the city serving as key transportation routes. At that time, most residents lived on water or land that was regularly inundated.

“One of the best projects I’ve seen to cope with climate-related disasters is Bangkok in 1850. The city was 90 percent on water – living on barges on water,” said Koen Olthuis, founder of Waterstudio, a Dutch architecture and urban planning firm.

“There was no flood risk, there was no damage. The water came, the houses moved up and down,” he said by telephone from the Netherlands.

Olthuis started Waterstudio in 2003 because he was frustrated that the Dutch were building on land in a flood-prone country surrounded by water, while people who lived in houseboats on the water in Amsterdam “never had to worry about flooding”.

His firm now trains people from around the world in techniques they can adapt for their countries. It balances high-end projects in Dubai and the Maldives with work in slums in countries such as Bangladesh, Uganda and Indonesia.

One common solution for vulnerable communities has been to relocate them to higher ground outside urban areas – but many people work in the city and do not want to move.

Olthuis says the solution is to expand cities onto the water.

Waterstudio has designed a shipping container that floats on a simple frame containing 15,000 plastic bottles. The structure can be used as a school, bakery or Internet cafe.

Waterstudio’s aim is to test these containers in Bangladesh slums, giving communities flood-safe floating public structures that would not take up land, interfere with municipal rules or threaten landowners who don’t want permanent new slums.

“Many cities worldwide have sold their land to developers… and now when we go to them, we say, ‘You don’t have land anymore, but you have water,’” Olthuis said. “If your community is affected by water, the safest place to be is on the water.”

Testing the Waters: Floating home development in Florida

By Amy Martinez
Florida Trend
February.2015

 

A 2013 U.S. Supreme Court ruling could lead to a first-of-its-kind floating home development in south Florida.
(Amy Martinez)

 

 

In 2005, Hurricane Wilma destroyed a pair of dilapidated marinas in North Bay Village where Fane Lozman, a former Marine pilot and software developer, kept a two-story floating home.
The Category 3 storm struck from the south, scattering splintered docks and other large debris into more than a dozen neighboring floating homes.
For years, Lozman had relished the camaraderie and convenience of living on Biscayne Bay, especially the easy access to deep-sea diving and fishing and his favorite Miami Beach restaurants. “Your speedboat was tied up right outside your front door. And you could enjoy the south Florida water lifestyle immediately and at any time,” he says.
After Lozman’s floating home, which had been docked at the north end of the marina community, emerged relatively unscathed, he quickly began looking for another place to anchor. In 2006, he had his home towed 70 miles north to Riviera Beach and rented a slip at a city-owned marina.
His new neighbors told him not to get too comfortable, however, because a planned, $2.4-billion marina redevelopment project soon would displace them. Lozman sued Riviera Beach to stop the project. And that led to another dispute, which eventually wound up before the U.S. Supreme Court.
In 2009, after failing to evict Lozman in state court, Riviera Beach went to federal court, seeking a lien for about $3,000 in dockage fees and nominal trespass damages.
The city argued that because Lozman’s floating home could move across water, it was a vessel under U. S. maritime law. A federal judge in Fort Lauderdale agreed, and the home was seized, sold at auction and destroyed by Riviera Beach, which cast the winning bid.
Lozman countered that his home was similar to an ordinary landbased house and should have been protected from seizure under state law. The home consisted of a 60-by- 12-foot plywood structure built on a floating platform — with no motor or steering — and could move only under tow.
Lozman’s appeal caught the Supreme Court’s eye. And in early 2013, it handed him a victory. Justice Stephen Breyer wrote in the majority opinion that because Lozman could not “easily escape liability by sailing away” and because he faced no “special sea dangers,” his home was not a vessel and not subject to seizure under maritime law. Lozman is still seeking compensation from Riviera Beach for his home’s destruction.
After the Supreme Court’s ruling, Kerri Barsh, a Greenberg Traurig attorney who helped argue Lozman’s case on appeal, contacted Netherlands-based Dutch Docklands, a developer of floating homes.
Founded in 2005 by architect Koen Olthuis and hotel developer Paul van de Camp, Dutch Docklands had designed hundreds of floating homes in Holland and was looking to expand to the United States. Barsh believed the high-court ruling created an opening for the company to pursue a first-of-its-kind floating home development in south Florida.
It meant, for example, that buyers could get a mortgage and homeowners insurance, though they’d also have to pay property taxes. The Coast Guard couldn’t enter their homes to inspect for life jackets and other safety measures — and “if a gardener or maid is injured on your property, you don’t have to comply with strict workers’ comp standards,” she says. “You also may be entitled to a homestead exemption.”
Dutch Docklands now is proposing a collection of multimilliondollar floating homes at a privately owned lake in North Miami Beach. Plans call for 29 man-made, private islands that are attached to the lake bottom with telescopic piles to guarantee stability.
Each island would cost an estimated $15 million and include a 7,000-sq.-ft. home, infinity pool, sandy beach and boat dockage, plus access to a 30th “amenity” island with clubhouse. The target market is celebrities and wealthy foreigners who want both privacy and proximity to downtown Miami, says Frank Behrens, a Miami-based executive vice president at Dutch Docklands.
“Buying your own island is a very complex process, and yet it’s a dream a lot of people aspire to,” he says. “Basically, what we’re offering is a way to realize that dream. Within two minutes, you can be on land and go to a Heat game or fancy restaurant.”
Historically, floating homes have not been widely embraced in Florida. A case in point is Key West’s Houseboat Row, which started in the 1950s as a playground for the rich, but in the 1970s deteriorated into floating shacks and live-aboards. In the 1990s, then-Mayor Dennis Wardlow repeatedly criticized Houseboat Row as an eyesore and environmental hazard. And by 2002, the community’s residents had been evicted and moved to a city-owned marina at Garrison Bight.
Today, the city marina has 35 floating homes and won’t accept any more. “We prefer to take in a registered marine vessel that’s Coast Guard certified,” says marina supervisor David Hawthorne. “Most marinas have moved out of it because of the liability, and there’s just more money in” short-term boat rentals.
To succeed in Florida, Dutch Docklands will have to change perceptions. The company promotes its brand of floating homes as a response to rising sea levels and climate change. And south Florida — as ground zero for sea level rise — could prove a receptive audience. Because of how they’re anchored, the floating homes move vertically with the tides, but not horizontally, enabling them to adapt to longterm climate changes and also hold steady in storms, Behrens says.
He hopes to begin construction next year at Maule Lake, a former limestone rock quarry with direct access to the Intracoastal Waterway. But his plans may be optimistic. The company recently filed for zoning approval and still faces questions about environmental impacts, the homes’ ability to withstand hurricanes and visual effects on the surrounding community.
“One of the big struggles we’ve had in this state is coming to grips with the fact that there’s a finite amount of land and water,” says Richard Grosso, a land-use and environmental law professor at Nova Southeastern University. “We tend to not recognize the importance of open space — the aesthetic and psychological value of it.”
Condominium towers — some pricier than others — surround Maule Lake. Behrens says local residents are understandably concerned about the project.
“If all of a sudden, a foreign developer comes and says, ‘Hey, we’re going to build private islands on this lake,’ I’d be upset, too,” he says. “But if you live in a $200,000 condo, and you get a $15-million private island on the lake in front of you, where a celebrity lives, you can imagine that the value of your real estate will go up.”
Even if all goes as planned for Dutch Docklands, it’s unlikely to spark copycat projects throughout Florida. Maule Lake presents “a pretty unique set of circumstances,” says Miami environmental lawyer Howard Nelson. At 174 acres, it’s big enough to accommodate a floating development without blocking boats — “and there’s very few bodies of water where the submerged land is privately owned,” says the Bilzin Sumberg attorney.
Meanwhile, Lozman has bought 29 acres of submerged land on the western shore of Singer Island in Palm Beach County. He says he’s talking with developers about building his own floating home community.
“I could see maybe 30 floating homes out there one day,” he says. “It would essentially duplicate the North Bay Village community that was destroyed in Wilma.”

Portrait: Waterstudio.nl, The Netherlands

 

Archi-News, February 2015

Facing the city planning and climate changing challenges, the Dutch office Waterstudio.nl chooses to work principally towards flexible strategies and large scale floating architecture projects proposing sustainable solutions.

In the Netherlands, one quarter of the country being under sea level, the architects are considering the ways to rethink the built environment. Koen Olthuis (*1971) is one of them. Founder of Waterstudio, he studied architecture and industrial design at the Delft Technology University. As per his words, we treat our cities as if they were static and we don’t stop erecting fixed urban elements, which after 50 years become obsolete and useless. But the to-morrow’s city is dynamic, hybrid, flexible and environment friendly, a moving town, which reinvents itself constantly. The architect’s work is more precise in order to especially respond to the pressing needs of climatic changes. Koen Olthuis proposes to live on the water, with the water. The first town created in this spirit is under construction between The Hague and Rotterdam. Called « The New Water », this 1200 house urban development takes place in the polder zone, intentionally filled with water after a few centuries of artificial draining.
Strict rules limit the volume authorized above sea level. This constraint gives life to a rather sophisticated design and to interesting spatial solutions, particularly a naturally lighted basement, large glass surfaces, parts with wood and a white Corian® curved frame running along the façade. First one of the 6 buildings foreseen in this project, Citadel is also, with its 60 luxury apartments, the first floating building in Europe. Easy to reach from the side by a floating road, the building is composed of 180 modular elements, placed on concrete foundations. The norms are identical to those of a house on dry land. Another element of the New Water project’s first part: the Waterfront villa has a concrete base with a boathouse and a swimming pool. Three U-shaped volumes enable to optimize the viewpoints at each level. Corian® is used as the main covering material.
Waterstudio develops a revolutionary concept for the cruise ships terminal. A sculptural triangular floating construction (700 x 700 m) situated outside the bank, disposes of more than 160 000sqm of conference halls, cinemas, shopping areas, spas, restaurants, hotels, etc. The triangular ring raises at one place to create a smaller interior harbour. Covered with aluminium panels and partly with photovoltaic cells, the structure anchors itself to the seabed by cables with shock absorbers, enabling a vertical flexibility, whilst ensuring horizontal stability. Modern, light and transparent, the De Hoef villa shows in a concrete way that floating architecture has now reached the same level as its land counterpart. Realized with a steel frame, the construction is an amphibian structure, floating on water but surrounded by land on three sides. The choice of this type of structure results from the fact that « normal » houses are not allowed in this peat landscape.
With the project See Tree, Waterstudio proposes a new concept for the high-density urban green points. With many layers of trees, this floating structure, unattainable for man, uses the petrol offshore platforms’ technology. It would be the first 100% floating object designed and built for flora and fauna.

At the other end of the world, Koen Olthuis undertakes a huge project: design a floating town in the Maldives. The masterplan proposes a solution to the dramatic situation created by the rising sea level. These floating developments, especially, have a real positive impact on the poor communities living near the coast. The architect reminds that the most exposed cities are Mumbai, Dhaka and Calcutta because of their huge populations threatened by the water level increase. In these cities, millions of people live in dense slums along the water and are vulnerable to floods especially during the rainy season. “With the City Apps, based on standard maritime containers, we want to use the technical knowledge coming from our floating projects for the wealthy people.” They can be compared to Smartphone with applications adapted to different needs, such as a special programme for slums. In view of their flexibility and small size, the City Apps use the space available on water and are very convenient to be used as residences or schools, for instance.

The objective is to reach 10 000 containers in 5 years, rented in the whole world. “The importance given to slums has opened new opportunities and has put me in touch with many interesting and influential people who understand the necessity for the architects to use their influence and creativity to change the lives of millions of human beings, underlines also Koen Olthuis”.
His approach to improve the coastal towns throughout the world with these floating urban components is a real challenge. « It is just as if we had discovered a small part of the water potential to make the cities more resilient, sure and flexible. I believe that our projects and those of many architects, who use the floating technology as a tool, will open new norms for the cities ».
