The De Castillia 23 project, designed by Progetto CMR for Gruppo Unipol, has transformed a building left unfinished for over fifteen years into a modern complex for advanced tertiary use in the heart of Milan’s Isola district. The intervention stands out for its sustainable approach and energy efficiency, thanks to the use of BIM methodology and cutting-edge technological solutions.
The prismatic façade, composed of triangular glass panels, creates dynamic light effects and gives the building a unique architectural identity. Interior spaces have been redesigned to ensure comfort and functionality, with a significant increase in natural light and reduced energy consumption.
Fiandre contributed to the project by supplying porcelain stoneware surfaces from the Core Shade collection, integrated with Active Surfaces technology, which makes the slabs photocatalytic, antibacterial, self-cleaning, and anti-pollution. This innovative solution, combined with the Granitech® ventilated façade system, improves thermal insulation and durability, reducing maintenance costs and environmental impact.
The complex is powered by photovoltaic and geothermal systems and uses recyclable materials, contributing to the reduction of NOx and VOC equivalent to 200,000 sqm of green areas, in addition to the 2,000 sqm of real greenery included in the project. Interiors, clad with the Fjord collection, guarantee safety, aesthetics, and easy cleaning.
De Castillia 23 stands as a model of sustainable and innovative architecture, a true “smog-eating building” that combines design, technology, and environmental respect, marking an important step in Milan’s urban regeneration.
