STORY HIGHLIGHTS

The first units will be unveiled this month (June), with prices starting at $150,000 for a studio apartment, and going up to $250,000 for a family home

Amidst looming environmental crisis and rising sea level, a floating city is being made just 10-minute boat ride from Maldives’ Male city in the Indian Ocean.

According to CNN, the city will be designed resembling a brain coral. It will consist of 5,000 floating units including houses, restaurants, shops and schools, with canals running in between.

The first units will be unveiled this month (June), with prices starting at $150,000 for a studio apartment, and going up to $250,000 for a family home.

The developers are expecting residents to begin moving into the island in early 2024, with the whole city due to be completed by 2027.

The Maldives Floating City, developed jointly by the Dutch firm Waterstudio and the Maldives government, aims to house 20,000 people in less than five years.

Notably, this will be the second floating city in world. The first one was announced in April by the United Nations off South Korea’s second-largest city, Busan. Known as Oceanix City, it plans to provide homes for a community of 12,000 people, potentially rising to 100,000, with construction due to start in 2023.

This is “new hope” for the more than half a million people of the Maldives, said Koen Olthuis, founder of Waterstudio, the architecture firm that designed the city.

“It can prove that there is affordable housing, large communities, and normal towns on the water that are also safe. They (Maldivians) will go from climate refugees to climate innovators,” he told CNN.

Features of Maldives Floating City includes rainbow-colored homes designed to attract local people. Wide balconies and seafront views are added onto each home. For transportation, residents will get around on boats, or they can walk, cycle or drive electric scooters or buggies.

Floating city“Tech is not the problem, but it is the regulatory framework that takes time to adjust,” Olthuis explained.

“Money talks and so this means when authorities understand that the cost of floating development are lower than the cost of destruction of waterfront infrastructure and properties then this next shift in city development will fly.”

the maldives is building a floating ‘island city’ in response to rising sea levels

 

WATERSTUDIO + DUTCH DOCKLANDS BUILD MALDIVES FLOATING CITY

Architecture firm Waterstudio has teamed up with Dutch Docklands to develop a floating city that responds efficiently to the threat of the rising seas in the Maldives. The project, which was created in collaboration with the local government, is located in a warm-water lagoon just minutes away from the Maldivian capital. This first-of-its-kind ‘island city’ consists of 5,000 floating units, including dwellingsrestaurants, businesses, and schools, with canals running between them in a pattern similar to brain coral. Inhabitants are expected to begin moving into the complex in early 2024 while the entire city will be completed by 2027.

 

MODELED AFTER AN ACTUAL BRAIN CORAL

The Maldives Floating City serves as the beginning of a new era in which Maldivians return to the ocean through durable, environmentally friendly floating constructions. The newly unveiled project features a unique nature-inspired road and water canal system modeled after the efficient structure of actual brain coral. In this way, the complex projects and stimulates coral growth by creating blue ecosystems above and beneath the sea surface. Artificial coral banks will be linked to the city’s underbelly, encouraging natural coral growth. The lagoon’s submerged and protected coral reefs will act as a natural wave breaker, providing occupants with comfort and safety when combined with the interconnected grid of floating structures.

 

A SEA-LEVEL RISE-PROOF URBAN DEVELOPMENT

The architects at Waterstudio and the developers at Dutch Docklands envision the floating metropolis as a next-generation structure that balances sustainability and livability. The project is being created as a practical solution to the hard reality of sea-level rise, rather than just a future ideal. Its smart infrastructure and dynamic, adaptable configuration can respond to weather and climate change, as the city will rise with the tide.

The structure protects and enriches the pristine maritime ecosystem by employing innovative sustainable development technology and ecological best practices. The project seeks to deliver security and development space to the Maldives, as well as a mix of green technology, safety, commercial feasibility, and a healthy new lifestyle that will serve as the foundation for future floating cities. As a result, the Maldivians’ fate will be rewritten from climate exiles to climate innovators.

  • A Dutch developer is building a sprawling, floating city in the Maldives.
  • The city is slated to house 20,000 people in a web of 5,000 floating buildings.
  • These buildings will include homes, shops, and even schools — all located 10 minutes away from Male.

A Dutch architectural firm is on a mission to create a floating city located just 10 minutes away from Male.

The Maldives Floating City, designed by Dutch firm Waterstudio, is an expansive mass of modular floating platforms in the pattern of a brain coral.

Koen Olthuis, the founder of Waterstudio, the architectural firm behind the city, told Insider that the project is a collaboration between the Dutch Docklands, a local developer, and the local government in Male. One of its aims is to free up more room for housing on the mainland.

Olthuis told Insider that building the floating city would also offer a solution to the threat of rising sea levels for generations to come.

“It will be a walkable city with floating streets, utilizing boats for the transport of goods and people within the city, and to the capital city of Male,” Olthuis said.

 

He added that the cost of living in the city itself would be comparable to local land-based developments in the Maldives.

“In 2027, we should have 20,000 people living in 5,000 houses,” Olthius estimated.

According to CNN, the city will be opening up its first units for viewing this month, with prices starting at $150,000 for a studio apartment, and going up to $250,000 for a family home. The developers expect residents to begin moving into the island in early 2024, with the whole city due to be completed by 2027.

Per the developer’s press release, the city will comprise modular, hexagonal segments connected to an outer ring of barrier islands. The bottom portion of the city will be attached to stabilizers that buttress it against the waves while also keeping the buildings and structures safe against the current.

Maldiividele plaanitakse ehitada ujuv linn kaitseks maailmamere tõusu eest

Maldiividele plaanitakse ehitada ujuv linn kaitseks maailmamere tõusu eest
Linn hakkab asuma ligi viiel tuhandel väikesel ujuvsaarel.

India ookeani saareriik Maldiivid asub vaid mõni meeter üle merepinna ning maailmamere tõus kliimasoojenemise tagajärjel ähvardab need saared kiiresti vee alla jätta. Selle vastu pakub lahenduse Hollandi disainifirma, mis ehitab ujuvaid linnasid.

Ujuvad saared pole iseenesest midagi uut, neid leidub nii Aasias kui Lõuna-Ameerikas ja neid on kasutanud elamiseks pärismaalased aastatuhandeid. Kinnisvaraarendajatele on ka juba pikka aega tundunud ujuvad saared väga ahvatlevad, sest maapinda ju pole vaja ning tagatud on vaade veekogule. Kuid selliste eluruumide muutmine moodsaks kinnisvaraks on alati olnud keeruline.

Ujuva elukoha pakub välja Hollandi disainistuudio Waterstudio koostöös Hollandis asuva Dutch Docklandsi ja Maldiivide valitsusega, et ehitada üleujutusohus Maldiividele selline linn, mis kunagi vee alla ei jää. See hakkab kerkima koos merevee tasemega. Praegu on Maldiividel 80% protsenti riigist vähem kui meetri kõrgusel merepinnast ja kui maailmamere tase peaks saja aasta jooksul meetri jagu tõusma, jääks enamus riigist vee alla.

Ujuv linn saab värvikirev, kesksel kohal on muidugi vesi ja veeteed.

Firma on ujuvaid maju disaininud isegi Läänemere äärde ja ehitanud Madalmaadesse mitmeid ujuvaid saari. Maldiivide projekt on siiski ambitsioonikam – laiendatav ala peab mahutama väikese linna jagu elamispindu ning kuna tegemist on ookeaniga, siis peaks see vastu pidama ka suuremale lainetusele ja tuultele.

Ujuv asula hakkab asuma soojaveelises laguunis korallrahude vahel kümneminutilise paadisõidu kaugusel Maldiivide pealinnast Malest ning Male rahvusvahelisest lennujaamast. Esimene omataoline «saarelinn» pakub revolutsioonilist lähenemist säästvale eluviisile taevasinise India ookeani taustal. Futuristlik unistuste maastik hakkab hõljuma paindlikul ja funktsionaalsel «võrgul» üle 200 hektari suurusel alal.

Ujuvasse linna on planeeritud elamispinnad kümnele tuhandele elanikule, majad asuvad ligi viiel tuhandel alusel, millele tulevad lisaks majadele veel ka restoranid, koolid ja kauplused. Moodulite vahel on kanalid ja sillad, et saaks nii paadiga kui jala liikuda.

Esimesed elanikud kolivad ookeanil hulpivasse linna sisse 2024. aastal ja kõik saab valmis 2027. aastaks.

Elemendid, millest saar ehitatakse, hakkavad paiknema korallimustrit meenutavalt. Korallid kaitsevad linna ookeanilainete eest.

Kuigi ujuv kinnisvara võib tunduda pigem vallasvarana või laeva või pargasena, mida saab ühest kohast teise viia, siis Maldiividel läheb see kirja kinnisvarana, millele saab laenu võtta ning millel on kindel postiaadress. Minema liikuda sellega ei saa.

Elektrit toodetakse taaskasutatavatest allikatest ning jäätmete vedu tahetakse ka lahendada roheliselt, nii et midagi ei peaks ära viskama. Prügi ladustamine on ujuval saarel võimatu ning merre ei saa ka midagi jätta. Pealegi on linna asukohas ohustatud korallid.

A LEBEGŐ VÁROS HÚSZEZER EMBERNEK AD MAJD OTTHONT

Gigantikus úszóvárost építenek a Maldív-szigeteknél

forrás: Youtube/DutchDocklands Maldives

Húszezer lakosnak otthont adó, úszó város épül az Indiai-óceánon, a Maldív-szigeteknél. A CNN online kiadásának hétfői cikke szerint a klímaváltozás miatt emelkedő tengerszint kihívására választ adó projekt öt éven belül készül el teljesen.
Az agykorall mintázatához hasonlóan tervezett város ötezer vízen lebegő egységből áll majd, házak, éttermek, üzletek és iskolák is lesznek, közöttük pedig csatornák futnak. Az első egységeket ebben a hónapban mutatják be, a lakók 2024 elején kezdhetnek beköltözni, az egész város pedig 2027-re készül el.

A város egy türkizkék lagúnában, mindössze tíz percnyi hajóútra Malétól, a Maldív-szigetek fővárosától épül a Dutch Doklands holland ingatlanfejlesztő és a Maldív-szigetek kormányának közös vállalkozásaként.

Az 1190 szigetből álló Maldív-szigetek a világ egyik legsebezhetőbb országa az éghajlatváltozás szempontjából: területének mintegy 80 százaléka fekszik kevesebb mint egy méterrel a tengerszint felett, és mivel az évszázad végére akár egy métert is emelkedhet a tengerszint, szinte az egész ország víz alá kerülhet.

Az úszó várost tervező Waterstudio építésziroda alapítója, Koen Olthuis szerint a vízen lebegő város új reményt adhat a Maldív-szigetek több mint félmillió lakosa számára.

Létrehozása bebizonyíthatja, hogy létezik biztonságos és megfizethető megoldás nagy közösségek számára

– fűzte hozzá.

A 2000-es évek elején alapított Waterstudio az elmúlt két évtizedben több mint 300 úszó otthont, irodát, iskolát és egészségügyi központot tervezett világszerte.

Hollandia élen jár ebben a kérdésben, az éghajlatváltozáshoz való alkalmazkodás megoldásaival foglalkozó Global Center on Adaptation (GCA) központja is egy úszó irodaépület Hollandiában, ahol úszó parkok és egy úszó tejgazdaság is található.

A Maldív-szigeteki projekt keretében kevesebb mint öt év alatt tervezik felépíteni a 20 ezer lakosnak otthont adó várost. Bár más úszó városok is épülnek, köztük a dél-koreai Puszanban tervezett Oceanix City, vagy a Balti-tengerre tervezett úszó szigetek, egyik sem vetekedhet ezzel a léptékkel és gyorsasággal.

A Maldív-szigeteknél épülő város színes házakkal, széles erkélyekkel és tengerparti kilátással vonzza a helyi lakosságot. A lakók csónakokon közlekedhetnek majd a lagúnákon vagy gyalog, kerékpárral, illetve elektromos robogókkal az utcákon.

Az árak Olthuis szerint versenyképesek: 150 ezer dollárnál (57 millió forint) kezdődik egy lakás és 250 ezer dollárnál (95 millió forint) egy családi ház ára.

A moduláris egységek egy helyi hajógyárban készülnek, majd az úszó városba vontatják őket. Miután a helyükre kerültek, egy nagy víz alatti betontesthez rögzítik őket, amely teleszkópos acélcölöpökkel kapaszkodik a tengerfenékbe. A környező korallzátonyok természetes hullámtörőként védik a várost, amely így szelíden ringatózik a vízen.

Olthuis reméli, hogy az úszó város olyan válasz lehet az éghajlatváltozásra és az urbanizációra, amely egyszerre praktikus és megfizethető.

Te wyspy znikną z powierzchni Ziemi. Jedynym ratunkiem jest pływające miasto

W emitowanym w poniedziałek 20 czerwca w Polsat News programie Debata Dnia poseł Janusz Kowalski z Solidarnej Polski przekonywał, że zmiany klimatyczne to tylko ideologia, a na świecie nic się nie zmienia, bo “czasami jest ciepło, a czasami jest zimno i zawsze tak było”. Tymczasem po drugiej stronie świata, mieszkańcy Malediwów przygotowują się do tego, że ich kraj w ciągu najbliższych stu lat całkowicie zniknie z powierzchni Ziemi.

  • Malediwy to kraj wyspowy, który może zniknąć z powierzchni Ziemi w ciągu zaledwie 80 lat.
  • Ponad 80 proc. jego powierzchni położona jest mniej niż 1 metr n.p.m. Prognozy wskazują, że na skutek zmian klimatycznych poziom morza do 2100 roku wzrośnie o metr.
  • Władze Malediwów we współpracy z holenderskim biurem projektowym rozpoczęły budowę pierwszego pływającego miasta, do którego będą mogli się przenieść mieszkańcy znikających wysp.

Ostatnie słowa poprzedniego akapitu brzmią brutalnie, choć nie ma w nich ani grama przesady. Malediwy położone są na 1190 mikroskopijnych wysp, których powierzchnia nigdy nie wznosi się na więcej niż na metr wysokości. Zważając na to, że woda w otoczeniu Malediwów na skutek ocieplenia klimatycznego spowodowanego przez człowieka podniesie w najbliższych stu latach swój poziom o ponad metr, pół miliona mieszkańców tego kraju zostanie bez dachu nad głową oraz bez lądu, na którym można by było ten dom wybudować.

Pływające miasto na Malediwach – wizualizacje

Pływające miasto na Malediwach już powstaje

Niezmiernie zatem cieszy, że zaledwie kilka minut od archipelagu Malediwów siłami specjalistów powstaje całe pływające miasto, w którym znajdą się zarówno domy mieszkalne, szkoły, przedsiębiorstwa rolnicze, parki, kawiarnie, sklepy jak i punkty usługowe, które samodzielnie będą mogły służyć nawet 20 000 mieszkańców. Fakt, że cała konstrukcja miasta powstanie w ciągu zaledwie pięciu lat i będzie unosiła się na wodzie jest kluczowy. Niezależnie od tego ile woda się podniesie w tym rejonie świata, miasto zawsze będzie znajdowało się na jej powierzchni. Warto tutaj zauważyć, że podobne projekty budowane są także w Korei Południowej czy na Morzu Bałtyckim.

Tak będzie wyglądało pływające miasto na Malediwach

Za budowę pływającego miasta odpowiada wspólnie rząd Malediwów i holenderski deweloper Dutch Docklands. Za projekt natomiast odpowiada holenderskie Waterstudio, które od ponad dwudziestu lat projektuje pływające domy, szkoła czy ośrodki zdrowia i ma na swoim koncie już ponad 300 takich budynków.

Circondata dalle acque cristalline delle Maldive, a soli 10 minuti di barca dalla capitale Male, è in costruzione una città galleggiante progettata per ospitare fino a 20 mila persone.

Il progetto – una joint venture tra lo sviluppatore immobiliare olandese Dutch Docklands e il governo delle Maldive, firmato dallo studio di architettura Waterstudio – è un tentativo di risolvere il problema dell’innalzamento del livello del mare, a cui le Maldive sono estremamente vulnerabili: l’arcipelago, composto da 1.190 isole che emergono per meno di un metro dal livello del mare, potrebbe essere completamente sommerso entro il 2100.

Dal punto di vista urbanistico, Maldives Floating City ha una forma che ricorda quella del corallo cerebrale e si compone di 5.000 unità galleggianti che ospiteranno case, ristoranti, negozi e scuole, collegate attraverso un sistema di ponti, canali e banchine. Ciascun modulo abitativo viene costruite in un cantiere navale locale, quindi rimorchiato e trasportato nella città galleggiante. Una volta posizionato, viene fissato a un grande scafo subacqueo in cemento ancorato al fondale tramite palafitte telescopiche in acciaio che gli permettono di fluttuare assecondando il moto ondoso.

Alcune unità sono già in via di completamento e i primi residenti potranno trasferirvisi all’inizio del 2024, mentre si prevede di completare l’intera città galleggiante entro la fine del 2027. Ogni residenza sarà affacciata sul mare, avrà una superficie che va dai 100 metri quadrati (a cui si aggiungono 40 metri quadri di terrazza sul tetto) in su e prezzi che partono dai 250 mila dollari.

L’impatto ambientale di questa città galleggiante “è stato rigorosamente valutato da esperti locali di coralli e approvato dalle autorità governative prima dell’inizio della costruzione” ha spiegato alla CNN Koen Olthuis, fondatore di Waterstudio.

Mesto prihodnosti že raste na morju #video

2022.June.20

Maldive sestavlja več kot tisoč otokov in država ima že leta velike težave z naraščajočo gladino morja, ki je že pogoltnilo marsikatero človeško naselje. Število klimatskih beguncev naj bi se povečalo za več kot pol milijona v naslednjih letih. Zato je bila maldivijska vlada prisiljena ukrepati in kot odgovor na spremembe v naravi se je rodila ideja o plavajočem mestu.

Ta mesec bodo javnosti predstavili prve hiše v novem mestu na Maldivih, ki bo v celoti zgrajeno na morju, poroča CNN. Gre za prvi obsežni projekt lokalne vlade v boju z globalnim segrevanjem in naraščajočo gladino morja. Novo mesto, ki se bo nahajalo deset minut vožnje z ladjo od maldivijske prestolnice Male, bo do leta 2027 imelo več kot pet tisoč hiš in okoli 20 tisoč prebivalcev.

Plavajoče mesto

Država Maldivi, ki ima več kot tisoč otokov, ima že leta velike težave z naraščajočo gladino morja, ki je že pogoltnilo marsikatero človeško naselje. Število klimatskih beguncev naj bi se povečalo za več kot pol milijona v naslednjih letih. Zato je bila maldivijska vlada prisiljena ukrepati in kot odgovor na spremembe v naravi se je rodila ideja o plavajočem mestu. “Gre za novo upanje prebivalcev. Dokazali bomo, da lahko na vodni gladini postavimo varne domove po ugodni ceni,” je za CNN projekt komentiral glavni arhitekt mesta Koen Olthuis.

Novo mesto bo zgrajeno do leta 2027, zaenkrat ima le delovno ime "Maldives Floating City". | Foto: waterstudioNovo mesto bo zgrajeno do leta 2027, zaenkrat ima le delovno ime “Maldives Floating City”. Foto: waterstudio

Hiše in druge zgradbe, ki bodo tvorile novo mesto, zgradijo v za to prilagojeni ladjedelnici. Vse zgradbe potem z ladjami odvlečejo do mesta, kjer raste novo mesto, ter jih pritrdijo na dno morja s posebnimi teleskopskimi jeklenimi “hoduljami”. Te zgradbam omogočajo, da kljubujejo valovom in se le rahlo zibljejo z morjem. “Pri načrtovanju mesta smo upoštevali najstrožje standarde glede zaščite okolja. Eden izmed zelo pomembnih ciljev gradnje je vzpodbujanje rasti koral,” je poudaril Olthuis.

Mesto bo tudi samozadostno. Sonce bo zagotavljalo elektriko, vse odpadke bodo reciklirali in jih ponovno uporabili. Tako bodo vse kanalizacijske vode uporabili za gnojila za rastline. Namesto klimatskih naprav bodo iz globine morja črpali hladno vodo, ki bo ohlajevala celotno mesto.

Mesta na vodi rastejo po celem svetu

Samo v lanskem letu so poplave po celem svetu naredile za več kot 70 milijard evrov škode. Do leta 2030 bo zaradi poplav v nevarnosti za več kot 600 milijard evrov nepremičnin, ki se nahajajo v urbanih naseljiv. Zato ni čudno, da plavajoča mesta rastejo po celem svetu. V južnokorejskem Buzanu nameravajo zgraditi plavajoče mesto za deset tisoč ljudi, medtem ko v Estoniji načrtujejo kar plavajoče umetne otoke.

Waterstudio - Maldives Floating City

De Malediven krijgen een drijvende stad in de buurt van de hoofdstad Male

By Roccarainola
2022.June.20

De archipel van de Malediven, ongeveer 1.000 kilometer ten zuidwesten van Sri Lanka, in de Indische Oceaan, wordt lange tijd beschouwd als een van de landen die het meest zijn blootgesteld aan de gevolgen van klimaatverandering: 80% van het grondgebied ligt binnen een meter boven de zeespiegel en naar schatting zou door de stijgende zeespiegel een groot deel ervan tegen het einde van de eeuw volledig onder water kunnen staan. Onder de mogelijke oplossingen waarmee de lokale autoriteiten zijn begonnen te experimenteren, is er een heel bijzondere: de bouw van een nieuwe drijvende stad die tien minuten per schip zal stijgen van de hoofdstad Malé en die na voltooiing plaats zal bieden aan maximaal 20 duizend inwoners.

Het initiatief is ontstaan ​​uit de samenwerking tussen de regering van de Malediven en het Nederlandse vastgoedontwikkelingsbedrijf Dutch Docklands; het project werd uitgevoerd door het in Nederland gevestigde architectenbureau Waterstudio, dat in het verleden betrokken was bij het ontwerpen van honderden drijvende woningen, kantoren, scholen en gezondheidscentra over de hele wereld .

De nieuwe drijvende stad zal verrijzen in een lagune van ongeveer 2 vierkante kilometer en zal duizenden gebouwen herbergen die zijn gebouwd op een reeks “drijvende eilanden”, waaronder huizen, restaurants, winkels, scholen en hotels. De gebouwen zullen worden uitgerust met elektriciteit die wordt verkregen uit fotovoltaïsche systemen en zullen beschikken over airconditioningsystemen met zeewater , die het water dat uit grote diepten wordt gepompt gebruiken om de kamers te koelen. Op de eilanden, gescheiden door verschillende kanalen, kunt u zich te voet, per fiets of met elektrische scooters verplaatsen.

De drijvende gebouwen worden op een locatie in het gebied gebouwd en vervolgens de lagune in gesleept, waar ze worden verbonden met een betonnen platform dat door telescopische stalen pylonen aan de zeebodem is bevestigd. Zowel deze structuur als het koraalrif rond de lagune zullen het mogelijk maken om de drijvende stad stabiliteit te geven, waardoor de trillingen die door de golven worden veroorzaakt, worden verminderd.

Eind juni worden de eerste gebouwen opgeleverd en begin 2024 kunnen de eerste bewoners er hun intrek nemen: het doel is om binnen vijf jaar een zelfvoorzienende stad te creëren die functioneert alsof ze op het vasteland staat. eind 2027.

Het is al lang bekend dat de Malediven door de klimaatverandering in het water dreigen te komen te staan ​​en tegen 2100 te verdwijnen. Het lijkt echter nogal ingewikkeld om concrete en haalbare oplossingen te vinden om de noodsituatie op lokaal niveau op te lossen, vooral gezien het feit dat volgens verschillende analyses de toezeggingen die tot nu toe op mondiaal niveau zijn gedaan om vervuilende emissies te verminderen en zogenaamde koolstofneutraliteit te bereiken , niet voldoende om een ​​verdere stijging van de temperatuur tegen het einde van de eeuw te voorkomen, met catastrofale gevolgen voor de hele planeet.

Voorlopig is een van de meest ambitieuze projecten die door de regering van de Malediven zijn gelanceerd, de bouw van het kunstmatige eiland Hulhumalé , dat ook een paar kilometer ten noorden van Malé ligt en de “City of Hope” is genoemd. Net als de nieuwe drijvende stad, was het in de eerste plaats ontworpen om de mensen te huisvesten die vandaag in de hoofdstad wonen – een van de dichtstbevolkte steden ter wereld – en degenen die in de toekomst misschien geen huis meer hebben. Zijn project vertoonde echter enkele opmerkelijke beperkingen, zoals het risico op schade aan het mariene milieu en het probleem van afvalbeheer.

Koen Olthuis, uitvinder van Waterstudio, vertelde CNN dat de milieu-impact van de drijvende stad zorgvuldig is geëvalueerd in samenwerking met mariene biologen en overheden, en dat het nieuwe project zal aantonen dat er “betaalbare huisvesting, uitgebreide gemeenschappen en veilige steden, ook op het water ».

Ook Patrick Verkooijen, hoofd van het Global Center on Adaptation (GCA), een internationale organisatie die zich bezighoudt met het evalueren van mogelijke oplossingen voor adaptatie aan klimaatverandering, lijkt het daarmee eens te zijn. Volgens Verkooijen kan het bouwen van drijvende gebouwen een functionele en economisch duurzame strategie zijn om het probleem van de stijgende zee aan te pakken: er moet echter nog veel gebeuren om dit soort projecten op grotere schaal en op een steeds efficiëntere en snellere manier te bouwen.

A floating city in the Maldives begins to take shape

 

 

Acity is rising from the waters of the Indian Ocean. In a turquoise lagoon, just 10 minutes by boat from Male, the Maldivian capital, a floating city, big enough to house 20,000 people, is being constructed.
Designed in a pattern similar to brain coral, the city will consist of 5,000 floating units including houses, restaurants, shops and schools, with canals running in between. The first units will be unveiled this month, with residents starting to move in early 2024, and the whole city is due to be completed by 2027.
The project — a joint venture between property developer Dutch Docklands and the Government of the Maldives — is not meant as a wild experiment or a futuristic vision: it’s being built as a practical solution to the harsh reality of sea-level rise.
An archipelago of 1,190 low-lying islands, the Maldives is one of the world’s most vulnerable nations to climate change. Eighty percent of its land area is less than one meter above sea level, and with levels projected to rise up to a meter by the end of the century, almost the entire country could be submerged.

But if a city floats, it could rise with the sea. This is “new hope” for the more than half a million people of the Maldives, said Koen Olthuis, founder of Waterstudio, the architecture firm that designed the city. “It can prove that there is affordable housing, large communities, and normal towns on the water that are also safe. They (Maldivians) will go from climate refugees to climate innovators,” he told CNN.

Hub of floating architecture

Born and bred in the Netherlands — where about a third of the land sits below sea level — Olthuis has been close to water his whole life. His mother’s side of the family were shipbuilders and his father comes from a line of architects and engineers, so it seemed only natural to combine the two, he said. In 2003, Olthuis founded Waterstudio, an architecture firm dedicated entirely to building on water.
At that time signs of climate change were present, but it wasn’t considered a big enough issue that you could build a company around it, he said. The biggest problem then was space: cities were expanding, but suitable land for new urban development was running out.

However in recent years, climate change has become “a catalyst,” driving floating architecture towards the mainstream, he said. Over the last two decades, Waterstudio has designed more than 300 floating homes, offices, schools and health care centers around the world.
The Netherlands has become a center for the movement, home to floating parks, a floating dairy farm, and a floating office building, which serves as the headquarters for the Global Center on Adaptation (GCA), an organization focused on scaling climate adaptation solutions.
Patrick Verkooijen, CEO of GCA, sees floating architecture as both a practical and economically smart solution for rising sea levels.

“The cost of not adapting to these flood risks is extraordinary,” he told CNN. “We have a choice to make: we either delay and pay, or we plan and prosper. Floating offices and floating buildings are part of this planning against the climate of the future.”
Last year, flooding cost the global economy more than $82 billion, according to reinsurance agency Swiss Re, and as climate change triggers more extreme weather, costs are expected to rise. One report from the World Resources Institute predicts that by 2030, urban property worth more than $700 billion will be impacted annually by coastal and riverine flooding.
But despite momentum in recent years, floating architecture still has a long way to go in terms of scale and affordability, said Verkooijen. “That’s the next step in this journey: how can we scale up, and at the same time, how can we speed up? There’s an urgency for scale and speed.”

A normal city, just afloat

The Maldives project aims to achieve both, constructing a city for 20,000 people in less than five years. Other plans for floating cities have been launched, such as Oceanix City in Busan, South Korea, and a series of floating islands on the Baltic Sea developed by Dutch company Blue21, but none compete with this scale and timeframe.
Waterstudio’s city is designed to attract local people with its rainbow-colored homes, wide balconies and seafront views. Residents will get around on boats, or they can walk, cycle or drive electric scooters or buggies along the sandy streets.

It offers space that is hard to come by in the capital — Male is one of the most densely-populated cities in the world, with more than 200,000 people squeezed into an area of around eight square kilometers. And prices are competitive with those in the Hulhumalé (a manmade island built nearby to ease overcrowding) — starting at $150,000 for a studio or $250,000 for a family home, said Olthuis.
The modular units are constructed in a local shipyard, then towed to the floating city. Once in position, they are attached to a large underwater concrete hull, which is screwed to the seabed on telescopic steel stilts that let it gently fluctuate with the waves. Coral reefs that surround the city help to provide a natural wave breaker, stabilizing it and preventing inhabitants from feeling seasick.
Olthuis said that the potential environmental impact of the structure was rigorously assessed by local coral experts and approved by government authorities before construction began. To support marine life, artificial coral banks made from glass foam are connected to the underside of the city, which he said help stimulate coral to grow naturally.

Residents can get around the city by boat, and it's only around a 10-minute ride to the capital and international airport.

The aim is for the city to be self-sufficient and have all the same functions as one on land. There will be electricity, powered predominantly by solar generated on site, and sewage will be treated locally and repurposed as manure for plants. As an alternative to air conditioning, the city will use deep water sea cooling, which involves pumping cold water from the deep sea into the lagoon, helping to save energy.
By developing a fully functioning floating city in the Maldives, Olthuis hopes this type of architecture will be propelled to the next level. It will no longer be “freak architecture” found in luxurious locations commissioned by the super-rich, but an answer to climate change and urbanization, that’s both practical and affordable, he said.
“If I, as an architect, want to make a difference, we have to scale up,” he said.
