Arrighetti's work is characterised by innovation and attention to form, as well as to architectural structures and construction details. His architectures bring together various fields of expertise, from urban planning to social and economic theory and practice. In the exhibition "Arrigo Arrighetti. A public architect", on view during Dropcity Convention 2023 from 16th to 23rd April 2023, Arrighetti's works are presented through a series of bespoke photographic images created by photographer and visual artist Pino Musi, alongside the architect’s own drawings of plans, sections and rooftops.

The young architects’ collective HPO designed the exhibition. HPO was asked to dialogue with Arrighetti's work, and drew inspiration from it to generate a creative conversation between master and student.
