The Plan of 1758 for the reconstruction of Lisbon's Baixa Pombalina followed principles of unparalleled efficiency and regularity. The grid of rectangular urban blocks with pre-designed street façades had a lasting impact on urban identity. Today, the original features of the blocks of flats allow renovation strategies that address changes in domestic life and present-day comfort demands: making use of alcoves and the enfilade to address intimacy; turning kitchens into social areas; using multiple entrances for flat division; introducing lifts according to staircase design. Recent renovations show how the flats' original features contribute to unconventional flexible layouts adapted to contemporary living.
