Four luxurious flats were designed for the Chesa Akelei building project, in a particularly privileged location. Geopietra® manufactured stone was included firstly because of the customisation possibilities, and secondly because of its technical features, a guarantee of safety and durability. Geopietra® in this case was able to install Abitasistema®: we’re talking about the tested and guaranteed procedure for the installation of Murogeopietra® on external EPS thermal insulation, specifically conceived to allow efficient design free from structural and technical constraints, and also able to guarantee energy savings and the best conditions for living comfort. The Geopietra® finish chosen for the exterior was Garda, combined with the light tone of the GeoBi Sabbia mortar. The finish with full joints of the mortar makes the masonry linear, creating a harmonious picture of soft tones, contrasting with the important circular play of the façade. Stone has also been used as a connecting element between inside and outside on the walls of the garage and the staircase of the residence, in perfect harmony with the porphyry tones of the floors of the transition areas.
