The Coliseo Theater of Buenos Aires is a traditional theater with capacity for 1700 people, property of the Italian Consulate. Its history dates from the late nineteenth century, when it had a series of changes in its facade and interior structure, forming in 1961 the current imprint, work of the architect Mario Bigongiari.

The project of restoration, remodeling, equipment and modernization of the building facilities that began in 2013, started from a deep study of diagnosis that allowed the design of an integral project covering not only its stage house, but all the building infrastructure, both in its aspects of technical functionality and aesthetics.

The renovation was designed and planned so that it could be executed in different stages during recess periods as not to interrupt the theater activity. Within this framework, conserving both the original architecture and its setting, the complete repair of the 1250 m2 of façade was completed and the interior of the theater house was re-designed, also recomposing sectors that had been intervened in recent years and did not encourage the functionality of it. In addition, the respective lighting projects, thermomechanical and electric installation totally new were carried out.

The stage house was completely remodeled and modernized. A new system of grid and fly galleries was built, involving a metal structure of 75,000 kg. The new equipment included 30 automated motorized battens and motorized point rail systems, according to international safety regulations. A new system for activating the automated safety curtain and a new stage floor were built. For the stage floor a criterion of maximum flexibility of geometric transformation was adopted, which makes it a unique polyfunctional system in Argentina. A demountable modular acoustic shell was designed and manufactured in the country, which allowed to improve the acoustics of the house. The advance in technology allowed the theater to receive international productions of shows and provide a greater degree of security for both the technical staff and artists.

The areas of technical and artistic support were designed to return the operational potential to the functionality of the plan, creating efficient and compact spaces and optimizing each environment and common space. Within the artistic area, 2 levels of dressing rooms (with ring intercom), 2 rehearsal rooms and a green room, were remodeled. Within the technical support area, warehouses, a dimmer's room and an auxiliary control room were remodeled, including the construction of a warehouse specially designed for the piano.
