Considering the very strict spatial organization regarding structural walls that cannot be moved nor demolished, our approach was:
The main entrance to both beauty center and the medical clinic is the one on the left looking from the staircase, which gives access directly to the reception, and in the same time divides the floor in two separate zones.
The space in the middle (social zone) needs easily movable furniture so it can be occasionally transformed into a cocktail party zone, along with the terrace. For this occasion the second entrance door would be opened for guests, meanwhile the main door would be closed, in order to avoid unnecessary passing through the medical clinic.
Manicure - Tables and chairs are contemporary, white and turquoise.
Pedicure - is placed in the room next to the bathroom, so the water can be easily supplied and it is near to the main drainage pipe. The floor is elevated 15cm so all the pipes can run beneath.
The door between the manicure and the massage is widened to give more space and access to the bathroom after massage.
Waiting room - it is placed in a less lit room, because it is the only one that doesn't actually need a lot of daylight. It gives access to the second bathroom.

Floors remain the same as per client's request. Walls are painted in white.
