The design process of Dr Américo Durão´s House is a manifestation of an “architectural design” coming out of Porto, of which Siza is universal master and Matos Ferreira a practitioner working alongside him, but which owes to both of them the possibility of emerging work, that is to come. An “architectural design” which informs about that movement of resistance and experimentation undertaken, among others, by these officiators in the elevation of doing the very same thing which is architecture.
