The apartment is on the top floor of an historic building. The young owner requested a redistribution of existing rooms to derive a living room, an open kitchen, a study on the mezzanine, a master bedroom with walk-in closet and a bathroom. The new interior partitions, made by dry technology, configure spaces in dialogue with the historic masonry. The design of spaces, furniture, countertops and lighting has been designed in a unified way: the lines of the cuts in the ceiling, which let you see the original wooden roof, recall the partitions and furniture (designed by the architects, too), which in turn are underlined by the arrangement and the effects of lighting fixtures. Even the play of materials and colors involves organically all horizontal, vertical and inclined surfaces, emphasizing the particular spaces.
