Other examples of underwater construction include, the Floating Seahorse villas that take the houseboat concept to the next level: each three-story retreat features an entire floor submerged beneath the sea. Brought to life by Kleindienst real estate and property developers, the villas are part of the Heart of Europe resort opening off the coast of Dubai.

On the outside hull, the architects used three main components: Glass Reinforced Plastic (GRP), steel, and acrylic. Connecting the acrylic to the hull was another challenge, as it required a highly flexible, long-lasting sealant that only about three companies in the world make -- of those, only one supplier was able to match the project's technical requirements.

Stretching across three levels, Floating Seahorse villas include two underwater bedrooms, an outdoor sun deck, and a rooftop with a glass-bottom Jacuzzi. Around 50 floating abodes will be ready to welcome guests at the end of this year, with a total of 131 villas expected by the end of 2017.

At just 9.5 centimeters thick, the floor-to-ceiling underwater windows make it seems like there's nothing between you and the fish. However they're not made of glass, as that would cause distortion and could not withstand the water pressure. Instead, the team looked to aquariums and submarines and used acrylic for its durability and crystal-clear views. <br />

Another example is the Floating House, designed by Singapore-based architect Dymitr Malcew, which aims to make the nomad life as leisurely and luxurious as possible. Each home is fully sustainable, built with its own water purification system and solar panels for electricity.

When building The Floating House, one of architect Dymitr Malcew's main goals was to complement the surroundings. Taking inspiration from nature, the design accentuates the landscape, featuring floor-to-ceiling glass curtain walls and an abundance of wood. Each room has easy-access to a wrap-around terrace, and enormous windows let in lots of natural light.<br />

Another ambitious project comes from Dutch developers ONW/BNG GO. The Citadel is Europe's first floating apartment building. It's part of the New Water development project, which will comprise six floating apartment buildings -- all designed to adapt to flooding and rising water levels.

The Citadel floating apartment building is home to 180 modules, which rest on top of a floating concrete foundation. A floating road connects the complex to the shore, so residents can park their cars on site. Dutch developers ONW/BNG GO designed the complex to be highly efficient, consuming 25 percent less energy than a conventional building of the same size.

This floating abode is all about sustainable, mobile living -- anywhere in the world. From the designers of Friday SA, a Portuguese design and engineering firm, Floatwing was built to travel and its modular design can be broken down and transported in two or three shipping containers. You can anchor where you wish, or motor around at a speed of up to 3 knots.

As stylish as it is sustainable, Floatwing homes come with a wine cellar, barbecue area and a rooftop terrace. As for sustainability, the designers chose eco-friendly materials such as cork and wood. It's energy efficient too, thanks to double-glazed panels for insulations and solar panels that cover up to 80 percent of energy consumption throughout the year.

House boats are nothing new in the Netherlands, where much of the land lies beneath sea level and is susceptible to flooding. Designed and constructed by +31ARCHITECTS, the 2,120-square-foot Watervilla de Omval floats on the Amstel River. It's a contemporary take on the traditional houseboat, featuring a curvaceous exterior, glass-front façade and a rooftop terrace to make the most of the surrounds.

You won't find any portholes aboard The ParkArk Oog-in-Al, but the contemporary houseboat still floods with natural light from enormous windows and skylights. Another custom project from BYTR architects, the copper-clad boat is moored on a leafy green canal in Utrecht right next to a footbridge. Due to its public location, the designers strategically planned the home's doors and windows to enable park and river views while maintaining a sense of privacy.

Breathtaking architecture found on and under water
CNN  — 

Europe’s first underwater restaurant is set to open in early 2019 in Lindesnes, in the south of Norway. The planned concrete structure features a 36-foot wide panoramic window and is designed to become part of the marine environment, with a menu that will focus on seafood.

These next-level underwater villas are making waves

The restaurant, called “Under,” is designed by Norwegian architectural firm Snøhetta, famous for its work on the Norwegian National Opera & Ballet and the Bibliotheca Alexandrina in Egypt. It will stand on the sea bed five meters below the surface, with thick walls designed to withstand the most variable sea conditions. It will be Snøhetta’s first underwater project.

“One of the benefits of this building is how it links nature and land, and how you can come safe from the land and in a very dramatic way go down through this concrete tube to the nature at sea level, and experience what normally is not experienced,” said Rune Grasdal, lead architect on the project.

Visitors can expect three levels and a capacity of up to 100 people. Below the entrance and the cloakroom there will be a champagne bar, to mark the transition between shoreline and ocean. Further down there will be a dining room, with two long tables and several smaller ones positioned in front of the large acrylic window, which will be 13 feet tall.

The restaurant will be completed in 2019.

Grasdal, who likened the building to a periscope, said it’s important people feel secure and not claustrophobic. To achieve this the design team took into consideration a myriad of elements, like natural materials – such as oak – and good lighting. Grasdal explains: “it should be an exciting experience but people should also feel secure and well when sitting down there.”

The structure will double as a marine biology lab.

Mural disappears with the tide

Head chef, Nicolai Ellitsgaard plans to offer a menu that will follow the flow of the seasons, with local vegetables in spring/summer and mushrooms and nuts in the winter, with shellfish influencing most dishes year-round.

Environmental considerations have guided the design, which is housed in a coarse concrete shell to invite mussels to cling on. Outside of opening hours, the unit will double as a marine biology research center, with planned experiments to study the behavior of marine life through shifting seasons.
