Studio founder Clavel Rojo took the first swim in the pool to mark the completion of its construction.
"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."

"Obviously the structure is totally safe but definitely there was some reluctancy to be the first to try it," added Clavel.
"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."
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.
The swimming pool will be part of a raised platform that is cantilevered on either side of two lift cores.

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."
Clavel hopes that the building can bring excitement to the city of Murcia, which was heavily impacted by the financial crisis.
Clavel Arquitectos has offices in Spain, Miami and Dubai. The studio previously designed a concrete house near Murcia that has a ten metre cantilever.
