The team composed of Stefano Boeri Architects and Diller Scofidio+Renfro won the international design competition for the regeneration of the Pirelli 39 site, in the Porta Nuova area. The contest was launched by Coima, the Italian real estate group which bought via public tender the property previously owned by the Municipality of Milan. The Italian-American team has beaten off the other five finalists admitted in the second phase of the competition: 3XN Architects; David Chipperfield Architects; Heatherwick Studio; Vittorio Grassi Architect & Partners; Wilmotte & Associés. The shortlist was chosen from 70 groups, with 359 architectural, landscape/urban design and engineering firms representing 15 countries (Italy, Austria, Belgium, Denmark, France, Germany, England, Norway, Netherlands, Switzerland, Spain, China, Colombia, Japan, USA) participating in the initial stage. This was the latest competition as a key part of the masterplan for the area -envisaged by guidelines issued by the Municipality of Milan and Coima- which includes other buildings under construction and planned (Gioia 22, Gioia 20, Pirelli 35). The plan envisages extension of Library of Trees Public's pedestrian areas to include a larger area of spaces accessible to the public, helping to regenerate the axis of Via Melchiorre Gioia, the intersection with Via Pirelli, Via Clelia and Via Bordino, the axis towards the Central Rail Station.
- New residential tower | Botanica (110 m): 1,700 square meters of vegetation, distributed on the floors so that the flora and forna will change the colours of the building as the seasons change, will absorb 14 tons of CO2 and produce 9 tons of oxygen per year, like a 10 thousand square meters forest. With 2,770 square meters of photovoltaic panels, the tower will be able to self-produce 65% of its energy needs. The building includes structural parts in wood that will decrease its carbon footprint, including 1,800 cubic meters of wood for the floors that will save up to 3,600 tons of carbon dioxide in the construction phases.
- Recovery of the existing building | P39 (97 m): the building will be adapted to meet the current standards of office spaces in terms of innovation and sustainability andin line with the Next Generation EU parameters; the project involves maintaining the character of the original building, while updating it in the plant equipment and energy performance and adjusting it structurally with the aim of enabling proper efficiency parameters solving its actual limits and allowing the reuse of the existing building rather than the alternative of demolition and total reconstruction.
- Bridge building | Greenhouse (27 m): using to the application of R.L. 18/2019, the project will redesign the separating ‘wall’ on Via Melchiorre Gioia by creating a new hub for events, shows and exhibitions, with meeting and wellness areas and a biodiverse greenhouse space as an extension of the Biblioteca degli Alberi that will be a dedicated laboratory to provide an immersive, educational, interactive and innovative experience among various plant species.
