Next to Palazzo Stratti stands the Model Building designed, on behalf of the Municipality, in 1870 by the architect Giuseppe Bruni, the same architect as the Town Hall Building.

The name Model was chosen because it had to be an architectural model for the renovation of the Piazza Grande. It occupies the place where the two churches of San Rocco and San Pietro were located at the north-east entrance of the square. The civic chapel of San Pietro during the Middle Ages was also the seat of civil justice debates and was flanked at the end of the plague in 1602 by the chapel of San Rocco. The chapel of San Pietro was demolished in 1822 and the church of San Rocco in 1869.

The Model Building was rented as an inn by the Hotel Delorme, named after its manager the Frenchman Antonio Delorme, cook of Baron Pasquale Revoltella. A prestigious hotel with rooms and apartments also for large families, toilets on each floor, restaurant and views of the square and the sea, and fairly low prices. The hotel closed in 1912 and since 2008 has housed the offices and management of Acegas-Aps, the company that manages water, gas and electricity supply services.

Original are the statues, the Telamons, located on the top floor, sculpted in the act of touching the genitals in a superstitious gesture.
