Rua das Flores, Porto

The aim of the project was to rehabilitate the building, preserving and enhancing its original architectural features.

According to the information gathered the building, built between the end of the seventeenth century and the beginning of the eighteenth century, has served various purposes, from housing to commerce, functioning also as a hotel and an educational building at some point. These different types of occupation are reflected in its current internal organization. The building, with an area of approximately 1200m2, presents a traditional eighteenth century Oporto building typology: stone masonry exterior walls, timber floors and some interior timber walls. The building has an.

NCREP developed this project in two phases: the 1st phase involved the structural inspection and diagnosis of the building; the 2nd phase, which was conducted in accordance with the results obtained in the 1st phase, consisted in the structural rehabilitation/retrofitting project.

The structural inspection and diagnosis carried out allowed to assess existing damage and its causes, through which was concluded that the building presents a reasonable state of conservation, and that it is possible to maintain a considerable part of its structural elements, through localized rehabilitation and (or) structural reinforcement. Furthermore, in order to monitor some damage detected and their evolution over time, a static monitoring system, consisting in crack meters, was installed.

Following the 1st phase, the structural project was carried out, seeking a solution witch complies with technical, economic and architectural requirements, taking into account the existing structural materials and systems. The structural project gave particular focus to the need to improve the connection between vertical elements (bearing walls) and between them and the horizontal ones (floors and roofs). This was made in order to promote the behavior of the building as a “closed box”, and thus allowing a good distribution of horizontal loads throughout the structural elements and increase its capacity resistant to such loads.
