Abstract. The house and farm of Valflores, located near Lisbon, are an important evidence of the Portuguese Renaissance civil architecture from the first half of 16th century, built by Jorge de Barros, the overseer of the Portuguese king, D. João III, in Flanders. Its style has its roots in Italian villas. As was common at that time, the property was a villeggiatura site. In 1982 the house and the farm were listed as property of public interest. In 2000 the property was inserted in a Portuguese list of heritage at risk and in 2001 the property was in a state of pre-ruin. It was bought by the municipality in 2006. After 2007 a partnership between a Local Heritage Association (ADPAC), the Municipality of Loures and the Lisbon School of Architecture developed a series of initiatives for the safeguard and restoration of this Heritage. Several studies were performed, including multiple three-dimensional surveys on several occasions. Ultimately, these studies led to the development of a restoration project in 2016 for European funds application. At the present date, the restoration works are going on. The objective of this paper is the discussion of how three-dimensional documentation played a fundamental role on the several stages of this process, namely after 2007, permitting to gain insights about metrics, space and form distributions, deformations, structural condition, state of conservation, history, and allowing dissemination and public engagement.
