From the architects IPEA:
The design of this private library has started from a requisite of space from a bibliophile: to organize and expose a collection of books previously confined in boxes. It was proposed a dialogue between daily habits cultivated in a pre-existing house and a large garden area available.
The additional library’s area intended to maintain distance enough for the recognition of new volume autonomy as well as to be placed comfortably close enough to complement and connect existing balconies and external areas. The zone of transition between new and old volume was established by a generous garden, and its incorporation into the project was determined from distinct purposes of the openings.
