Once divided into small spaces, the last two floors of a building in the heart of Athens were redesigned by Zege architects and transformed into a two-storey penthouse with light aesthetics and unobstructed view. Its trademark is the floating staircase connecting the two floors. The rooms are totally unified on the top floor, while the design logic changes on the lower floor, with bedrooms and kitchen enjoying more isolation. The dining room has an unusually casual style and a leading role on the lower floor, while the bathrooms are very atmospheric, covered with white marble.
