This is the first monograph dedicated to the work of Nieto and Sobejano in several years. 394 pages to develop 21 projects carried out between 2004 and 2017 plus a comparative annex of sections. A double volume on the trajectory of this team of Spanish architects that also includes the projects that are being finalized, explained and developed with photographs and, as always, with plans and constructive details. Experts in working on historic buildings, the interventions of Nieto Sobejano in consolidated heritage are grafts that give rise to a new type of space. In them, the resonance of the past is permanent, and the tangible signs form a very dictionary for each project that expands the contemporary architectural language with neologisms.
