The building, with 5 floors plus 1 in the mansard and 1 attic floor, has 3 frontages (North, West, and South) and an annex to the South with two floors. It was, for a long time and until the end of 2016, occupied by office spaces.
In the 1950s, it underwent significant alterations. During those works, the wooden partition stair core was replaced by a reinforced concrete structure and brick masonry walls, and an elevator was introduced. The annex to the South was entirely rebuilt in concrete and new openings were made to allow the use of the -1 floor for parking.

Externally, the façades were subject to numerous modifications, including the replacement of some window bays with French doors, the extension of balconies, the addition of one floor, and the reconstruction of the roof.

All floors of the Main Building were fully occupied by office spaces, divided by plasterboard partitions, with the exception of five rooms on the 2nd Floor. In these rooms, located to the North and West, wooden wainscoting with tile panels was preserved, some in Neoclassical style, others with Pombaline patterns, along with decorative paintings on the walls and ceilings sharing the same thematic language.

In this intervention, the building was returned to residential use, with 12 units. The main changes were made to the interior, particularly in terms of partition walls. The circulation core and main structural elements were retained where no expansion occurred.

However, to enhance the South Elevation, a lightweight balcony structure was added on all floors, allowing the apartments to take advantage of the privileged river view.

The façades and principal architectural elements deemed characterizing features were maintained and duly restored: the plaster finishes, the window frame expression, the tiled roof, stonework elements, and so forth.
