The circular internal courtyard intensifies this reference, all the while providing the library’s interior with biophilic characteristics: natural environment, natural lighting, natural cooling.
The geometry of the new library results from the radial outlines of the existing building — as well as from the contours and the limits of the existing slope that delimits the excavation. Parameters that ensure optimal integration into the landscape and connection with the existing building volume.
The expansion’s roof is planted and appropriately landscaped, mostly with low vegetation and exposed concrete arranged in freeform curves; it constitutes a vital part of the two buildings’ outdoor area and contributes to the new building’s bioclimatic character.
A glass aerial corridor – acting as the new landmark – begins from the entrance level of the building complex and connects the existing library to the underground expansion, via a vertical core.
