Abstract: The aim of this work is to analyse the recovery methods and strategies of a high-rise steel building, an approach to restoration of the modern that may not always be based on specific standards and pre-established procedures. In the present case, the report raises the topic of the recovery of a structure from the 1960s, a symbol of International Style and Rationalism, commissioned by the State TV and built on the project by Domenico Morelli: the RAI skyscraper in Turin. Since this is a unique work in its design and architectural choices, the approach to a possible recovery begins with a detailed knowledge of the structure, through the analysis of documents, testimonies of the time and the architect’s concept. Subsequently, the analysis of the current state of the structure, focuses on the presence of asbestos and methods of remediation of this harmful material. In harmony with the architectural sign, we propose a technological, regulatory and sustainable adaptation, through solutions that concern the materials, services and areas of the skyscraper, moving from a global vision to a meticulous focus on details. The final proposal involves the skyscraper’s application for LEED certification, issued to buildings with low environmental impact.
