The project on Via Corio, in the Porta Romana district of Milan, involves the transformation of an attic space with a newly created pocket terrace, internally connected to the lower apartment already occupied by a family of four.

The master bedroom and en-suite bathroom were relocated to the upper level, alongside a flexible hybrid space designed for study, dining, and relaxation, complemented by a compact kitchen. The terrace represents the core of the intervention: its construction required a complex structural solution, as the fully glazed façade—set “out of alignment” with the building below—was supported by a custom trestle structure installed using a 30-meter crane.

The internal oak staircase was also particularly challenging, custom-shaped on site due to the constraints imposed by the existing timber floor structure.

From an energy standpoint, the sloped roof was insulated with polyurethane panels, completed with a new plasterboard lining and supported by an air conditioning system.

Relocating the master suite required a reorganization of the lower floor as well, where a grey lacquered wood filter volume now marks the entrance and connects the two levels. The attic floor was conceived as a fluid, light-filled space, with movable partitions and integrated walnut-clad volumes concealing storage and services.

The exposed roof beams were painted light grey, while brushed oak flooring was laid in a traditional Italian herringbone pattern. The terrace and bathroom are finished with Ceppo di Gré stoneware slabs by Marazzi.
