The project addressed the following specific issues:
Maintenance of the retaining wall. The retaining wall of variable height from 4 to 3 m, made of natural stone and partially plastered, was in poorly stable conditions. The existing wall was demolished and rebuilt in a length of 35 m, the new wall with structural functions is built in reinforced concrete and later covered with stones from the dismantling of the pre-existing wall. The final form reproduces exactly that of the original wall.

The tiles that cover the upper part of the wall (covered with stone) have great historical value, since some of them have rock art engravings (cupels). The original covers of the wall were numbered, dismantled, preserved and later replaced in their original position and sequence. The perimeter of the square was delimited by 8 tall trees. The trees were transplanted during the work and replanted at the end of the work.

Paving and channeling of rainwater. The original clay pavement has been removed and a new one made of Saltrio stone has been laid. The proposed pavement allows preserving the unitary and material aspects of the square. The 10 x 10 cm stone cubes were placed in parallel rows, following the direction of the steps of the church patio. The new pavement is waterproof and is grouted with cement mortar.

Rainwater is collected through a system of grids placed at the entrance to the plaza and then introduced into a channel dedicated to a mechanical pre-purification system (2 oil separators and 2 sand traps); once treated, the water is channeled and reintroduced into a natural receptor.

Furniture. A fountain was placed near the pedestrian staircase next to the churchyard. The fountain was made with an ancient block of Arzo marble, the water comes out of a brass faucet, recovered from the old fountain, and is screwed to a brass spout, supported by an IPE 100 natural oxidized steel profile. stone seats have been placed in the fountain, made up of large blocks of stone from Moltrasio, recovered from the excavated material from the square. The same type of seats was used at the entrance. Some of the boulders were also used for the construction of the stair steps under the retaining wall.

On the inside, structural consolidation work was carried out: in the basement, new walls were built and a new reinforced concrete slab (10 cm thick) was cast inside the original masonry; on the upper floors, the existing slab was replaced with a new one in reinforced concrete and metal beams, the surface of which was sown with porphyry aggregates from Cuasso al Monte and limestone from Moltrasio (Sasso di Caprino) and then smoothed.

The back wall of the original building was removed to gain space for the construction of the exposed concrete staircase, thus adding more rock surface to the interior of the building. Two new reinforced concrete walls and a new reinforced concrete slab were then built, which in addition to covering the new connection further consolidated the original building by connecting it entirely to the rock behind.

In the basement a bathroom was introduced which is separated from the corridor by a 3.5 cm thick curved concrete wall, on the upper floor the door connecting to the outside was changed into a window facing south and the existing roof was replaced. Everything else was left in its existing state or restored.

Externally, the façade of the building, which was also damaged, was restored, bringing back the original pictorial decorations and a new terrace was added to the existing one. The surface of both terraces was paved with re-used stones (Porfido di Cuasso al Monte, Sasso di Caprino, granite slabs and strips of white marble obtained from the re-use of ancient slabs with the names of the streets of the city of Lugano).

The original parapets have been maintained and modified to comply with the law; the new ones, also internally, are in rough oxidised iron.
