This paper presents an analytical framework for evaluating the impact of the two main processes identified in Madrid timber-framed courtyard buildings reinforcing the courtyard's crucial role in architectural heritage sustainability:their development caused dwellings to darken(1737–1950),and the existing challenge is to open new patios according to the listed buildings'protection *** findings in archival research and existing building assessments led to completed data collection and *** exploring construction expansion,from the house towards the collective prototype around a gradually reduced patio and dwelling darkening(1737–1786),buildings resulted in open,semiopen,underlighted and closed *** area on-site assessment uncovered the transition from the older low-rise type(1–3)floors to the modern closed model of up to(4–6)*** enlargements,consequently reducing original green areas and courtyards,call for reversing that process or formulating a new *** debates the partial demolition of listed buildings in upgrades and its agreement with the needed“blue courtyard”strategy(PGOUM),resulting from joining new rear individual patios to create a communal building block *** uncovered“in-between”type(1864),which integrates two open-air collective spaces,an inner courtyard and a back garden,appears challenging to explore.
