This historic theater, in the center of Covilhã, has been completely renovated to meet the contemporary requirements of cultural shows. The project modernized the technical and acoustic installations, while preserving the façade and other historic elements. Space restrictions prevented the installation of modern air conditioning and air renewal systems for years. GM collaborated in the process of optimizing the solutions to be installed and supported the construction inspection in the analysis of installers' proposals and in the dialogue with the design team.
