This paper focuses on the transformation of housing typologies by using a grammar-based methodology assisted by the use of space syntax measures. In this paper we start by describing three different types of housing buildings regarding their functionality by using syntactic measures. The studied buildings were constructed in Lisbon from the 18th to the 20th century and are representative repetitive cases in the city. The buildings’ descriptions are then used as part of the systematization of rehabilitation principles for the transformation grammar. We concluded that the particular characteristics of those buildings enable specific rehabilitation strategies to be carried out and that those different strategies may be integrated in the general grammar framework but defining specific sub-grammars.
