On a parcel of land in Paris's 17th arrondissement that is as long as it is narrow, where an obsolete tertiary building and overhead parking lot once stood, the Galia Group will shortly be delivering a mixed-use building combining 5-star hotels and operated offices. Here, we take a look at several of the trends driving today's city-building, from asset repositioning to new real estate uses and the integration of art, nature and culture into real estate assets, with Philippe Chiambaretta, architect and founder of the PCA-Stream agency, Brice Errera, President of the Galia Group, and Valeriya Savchuk, Director of Terlia.
