There are few cities in the world where architecture, both historical and contemporary, plays such a prominent role as in Barcelona in Spain. For most cities it is the intrinsic, functional and historical value of architecture that determines the importance assigned to an area, a building or a landmark. In Barcelona, architecture is also widely celebrated as an art form by visitors from all over the world. The development of architectural projects that not only co-exist but that are admired and appreciated alongside some of the world's most famous buildings, is both an extremely demanding and stimulating challenge. b720 Arquitectos, an international practice established by two Catalan architects and one from Madrid at the end of the 90's, has thrived on this challenge, providing architecture, masterplanning and design services to private and public sector customers.
