Dr. Barbosa de Castro Street. Árvore Association building, old manor house of the Jordão Family.

Some of the buildings display a functional typology with two fronts, typical of wider allotments, with two façades and two accesses. As is frequently the case in Porto, these buildings form interruptions on the built front, punctuated by façades with a certain apparatus, which emphasize symmetry and establishing a dialogue with the walled patios. These buildings either resulted from the agglomeration of the usual narrow lots, in allotment processes, or reflect the conservation of a partitioning of irregular spaces urbanized henceforth. Their size and potential led, in many cases, to their subsequently occupation by industries or services.
