The project concerns two apartments on two levels, connected by a staircase with a total area of 90 m². The aim is to redesign the premises in order to optimize the entire space and make it more practical, in particular with the addition of plenty of storage spaces. The staircase, formerly made of a very dark wood, has been redesigned to bring light and create an aesthetic and functional link between the two levels. The living spaces have been redesigned, the floors and ceilings have been leveled and standardized in order to create more consistency. The design of some custom-made furniture provide more storage spaces and a real reorganization of the bedrooms.
