The swimming pool, which will form part of the Odiseo casino爱博体育官网 and leisure complex, cantilevers 20 metres on each side of central supports.
爱博体育官网According to this makes it the longest overhanging pool in Europe.
Studio founder Clavel Rojo took the first swim in the pool to mark the completion of its construction.
爱博体育官网"We looked to the tradition whereby the creator has to test first his own creation," he told Dezeen. "This is something really imbricated in the pop culture, just think about the crazy scientist that tries some new vaccine on himself."
爱博体育官网"Obviously the structure is totally safe but definitely there was some reluctancy to be the first to try it," added Clavel.
爱博体育官网"So we thought it was powerful that I was the first to try it – jumping into the pool inn speedos in frozen water, that talks about the way we see life and architecture in my office."
爱博体育官网When the building is complete, the swimming pool will be located within an elevated forest that is being built as part of a leisure complex on the outskirts of the town of Murcia.
The forest, which will be enclosed by a latticework of pipes to help shade the plants, will stand on top of the three-storey building that will contain a casino, as well as a nightclub and restaurants.
爱博体育官网The swimming pool will be part of a raised platform that is cantilevered on either side of two lift cores.
爱博体育官网According to Clavel, the pool's large overhang was a result of the client making the decision to add it to the project once construction had begun.
"Even though the pool was in the first sketches of the building the client discarded it before we started the detailed design," he explained.
"They only decided to build it when the project was halfway of the construction process. That meant the structure was not ready to resist that new weight, so we came up with the idea of supporting it over the two more rigid existing elements, the stairs cores."
"We strictly reinforced those foundations, not been able to touch the building in any other point. On the other side we clearly had to go through the façade to get views from the pool to the horizon," continued Clavel.
爱博体育官网"Once it was clear that it was going to be a very extreme structure we just pushed it a little further, to the limit, producing this really fun experience for the users of swimming in a 20 meter cantilever, second in the world and probably the slimmest as far as we know."
爱博体育官网Clavel hopes that the building can bring excitement to the city of Murcia, which was heavily impacted by the financial crisis.
"Consider that Murcia, the city where Odiseo is being built, is as a small city, far from everywhere and extremely hit by the last crisis that devastated not only the economy but somehow the citizen's self-esteem," he said.
爱博体育官网"Cities like this have heritage, great architecture since Roman times. The question is: What is the architecture we are building for the next generations? Not every building but specifically some public architecture has the responsibility of being meaningful and fulfil the human need for monumentality."
Clavel Arquitectos has offices in Spain, Miami and Dubai. The studio previously designed a concrete house near Murcia that has a ten metre cantilever.
