The bar has an organic design and total openness to the terrace, with walls of glass allowing the interior to be seen from the outdoor spaces.

The terracotta tiles in shades of green and brown, designed by Openbook and produced by Viúva Lamego, blend in with the green of the surrounding garden, while the shape of the bar reflects that of the building.
