A home in Marbella, on the Mediterranean coast of Spain offers views of the sea while sunbathing or swimming in its rooftop glass-bottom pool.
Known as the Jellyfish House, it was designed by international architecture and design firm Wiel Arets Architects and features two means of navigating floors with a ‘fast’ and a ‘slow’ set of stairs that connect the home's four levels.
While the ‘fast’ staircase is enclosed in glass and leads from the exterior straight to the rooftop without connecting to the interior, the ‘slow’ staircase spans the entire length of the house with long treads and short risers, allowing those inside to house to go from the main entry in the ground floor to the terrace.
The house spans 650 square metres and includes three bedrooms on the first level and two guest rooms on the basement level. The guest rooms open up to a private terrace for the exclusive use of guests.
“As the ‘slow’ stair leads from the main entry to the guest bedrooms below, this area of the house is able to function as a separate entity,” the architects said.
The project’s most striking feature is the rooftop pool, which is cantilevered nine metres toward the Sierra Blanca mountain views and which weighs almost 60,000 kilograms. The swimming pool has an infinity edge, which makes it appear to merge with the sea in the distance. The pool has a glass-bottomed floor and a panoramic window at its interior facing edge, both of which were built with six-centimetre-thick security glass.
The pool can be seen from inside the house. The sunlight filters through the pool’s glass wall and floor, creating turquoise reflections throughout the interior. From the kitchen, it is possible to see those swimming in the pool, while another window connects the interior space with the living room and a terrace extends under the cantilevered pool.
The architects said light was a very important consideration in their design. The house is composed of poured in place white-concrete supported by one column at the right-rear edge of the pool and several smaller columns near the rear dining terrace. The interior walls were made with glazing to allow natural light to filter through the entire house. The bedroom closets are also finished in translucent glazing to help this sunlight diffuse.
“Taking full advantage of the ever-present Spanish sun, the Jellyfish House is an avant-garde expression of luxurious living; as most of its façades can be opened, and as its staircases are mainly outdoor, the house’s ever shifting boundaries between inside and outside are curiously blurred,” the architects said.
