This apartment located in the historical center of Caltanissetta is the result of the fusion of three smaller residential units that are part of a building with a low architectural value. To join the three apartments arranged in a horseshoe around the central body of the communal staircase I’ve practiced some cuts on the existing walls, that in addition to physically connect the portions of the building they responded to precise visual and perceptive rules of the new distribution of the interior spaces. A result of the openings practiced on the existing walls was the “comb effect” corrected by a long wardrobe made to measure.
