It doesn't look like it but this project was an engineering feat the land was just fill the pool needed to be piered into soild rock. The walls on both ends are concrete block reinforced and either rendered or cladeed to stone. The pool top is is honed travertine and the filtration equipment is housed underneath the house as we removed a heap of rock to create a space to store all equipment we have included a small kitchen, change room and toilet underneathj the house as well. The suspended stair case runs between the upper landing and the newly constructed pool deck. This was once a old tired piece of unusable land and now is a entertainers delight!
