The derelict existing structure was freed from the excessive number of internal walls, to create generous living spaces. The architects cut new patios and openings into the building to maximize the daylight. A new floor was added on the top of the existing building, introducing a large overhang roof made of white concrete that provides shadow to the interiors. The new rooms were designed with minimal features to enhance the green roof garden. The top floor opens up panoramic views into the rich greenery, thanks to full-height glass screens, giving the impression of a secluded oasis within the city centre.
