the barcelona-based studio’s project has exercised the integration of blending the building structure within an urban ensemble. with this, the design aimed to minimize its exterior volume by inverting the program’s logical order. this response has led to the exhibition spaces located below ground level, in such way that the emerging structure -above street level- only comprises of the public spaces. consequently, the volume’s reduced footprint has allowed the existing garden to be extended and improves the overall organization.
externally, the new extension’s cubic form is clad in sculptural concrete slabs; visualized as organized tiles that reinforce its expressiveness and autonomy with respect to the existing villa. in addition, the new build has been developed with an independent identity from its historical counterpart. in subtle ways, the extension has subtly reinterpreted elements to allow an architectural dialogue to be established between the two.
both buildings follow a central symmetrical plan and use geometry as a tool to spatially link the two schemes together. in the extension, this classical configuration also makes it possible to simplify the structural system and to organize the exhibition halls on the lower levels.
