The renovation process mainly focuses on the rooftop apartment as its inadequate waterproofing leads to leakage on the lower levels. The materials on the terrace have also deteriorated as a result of water leakage. Apart from these issues, the terrace consists of multiple materials which compromise the aesthetic quality of the penthouse. In order to improve the aesthetics and coherence, all the surfaces including the walls, the floors and the roof edges are finished with a very light pre- patinated zinc. It is Naturally resistant to corrosion and requires minimal maintenance.
