The Number 6

The Number 6 is the best renovation of 2015 according to Archdaily, the most visited architecture site in the world.


From 6 February 2015

The most beautiful house in the world

The Number 6 is the baroque palace a stone’s throw from Piazza San Carlo that Piero Boffa’s Building Group has transformed into a contemporary avant-garde condominium. The Building of the Year award from the American portal ArchDaily – 7 million visits per month, 2 million Facebook fans, 335,000 Twitter followers – has selected over 3,000 projects distributed in a global geography from Chile to Vietnam, including China, Australia and Europe; more than 18 thousand architects participated in the ArchDaily Building Award 2015 selections, including archistars and famous studios including Renzo Piano, Jean Nouvel, Álvaro Siza and Kengo Kuma. The Number 6 of Building was chosen from among the top 5 projects in the Restoration category by ArchDaily readers who selected it along with a house in central Portugal, the re-functionalization of a 16th century church near Madrid, the conversion of an ancient convent in Belgium and a green house in the center of the Vietnamese capital Hanoi.

The Number 6 was conceived to give back to the ancient Palazzo Valperga Galleani in Canelli di Barbaresco, in Via Alfieri 6 in the heart of Turin, the intrinsic vocation of a prestigious and noble “building of income”, which during the XVII and XVIII centuries dictated the most significant transformations still legible and recoverable today as architectural facies of the entire area. The building built in 1663 by Maurizio Valperga, and extended in 1781 by Michele Luigi Barberis, has undergone profound changes both in form and in use over the centuries. Palazzo Valperga Galleani is today a building with multiple interpretations: from architecture to art, from modern functionality to wellness. The architectural project was designed by the architect Luca Petrone, responsible for the design of Building; The Number 6 combines historical spaces, protected by the Superintendency of Architectural and Cultural Heritage of Piedmont, with the public art of the installations of the artist Richi Ferrero, sculptural elements and environments accessible to citizens and inserted as guest works in the last two editions of the exhibition Artist’s Lights.

The renovation, a few steps from Piazza San Carlo, covered a total area of ​​about 6,500 mq including the 5-storey building plus two mezzanine floors. It houses 36 apartments, 36 underground car garages, a modern Beauty & SPA for condominiums (sauna, Turkish bath and emotional shower) and a gym equipped with Technogym technology.
