For the Outdoor Jacuzzi, I tried to create a modern and linear design, with no many alterations to the present fabric. I suggest a glass canopy with metal frame, in order to let the light inside. This canopy is not a closed one from the side of the stair, so it les the air inside too. During the winter, the canopy will protect the Jacuzzi from the rain, and the air, but the temperature will be almost the same as the external one.
The cover of Jacuzzi is timber, such as the rest interventions (the timber shower and the timber footsteps). The lighting system consists of linear LED waterproof lights inserted into the stone walls.
