This third volume in the Compendium ARQ series is dedicated to buildings that build the city, contributing to the improvement of quality of urban life. Following an open call, the selections was in charge of a jury specially summoned for the occasion. The chosen projects were built after 2010 and within urban areas of Chile. They range from public buildings in small towns (where the project itelf creates the urban condition) to to apartment buildings embedded in the metropolis. The objective is to highlight those projects that are not afraid to face the complexities of the urban condition - from citizen demands to those of the real estate market - but, on the contrary, understand them as part of the wealth to which architecture must add.
