The Diagonal Zero hotel is part of the set of buildings built at the start of Avinguda Diagonal, in the junction between Ram­bla Prim and Taulat Street, directly opposite to the Fòrum building, and diagonally opposite to the Princess Hotel. The scheme is designed as a series of volumes aligned to the streets surrounding the site. As each of those rises towards the maximum height permitted by the planning regulations (100, 80 and 50 m), the building is shaped both in height and plan to link all of those volumes into one stunning entity.
