Introduction or preface

This paper describes the method employed for the restoration of the Maison La Roche and the Villa E-1027 buildings, considered emblematic for modern French architecture. The radical atten- tion to material conservation was the main objective, supported by substantial research of the archives and minute analysis of the existing buildings, the results of which are reported. Maison La Roche became a museum compliant with the requirements of a public utility building. A discussion is given of the study and restoration of the murals by Le Corbusier conserved at Villa E-1027, which has not yet found a new function.
