As architects, we have been inspired to make the most of pre-existing infrastructure of our city. This lead us to the project U125 that recycles a house located in Lomas de Chapultepec and that was orignally built in the 50s. We saw the potential of this building and had the vision to convert it into our firm’s headquarters; we preserved the house, giving it added value and a cutting-edge look. The house that originally had 300 sqm in 3 levels was recycled, transformed and extended. Today it hosts an office program of 604 sqm in 4 levels plus a terrace. Considering the equity value of the house was the guiding line for our design process. We respected the proportions, openings, entrances and volume preserving its original essence, achieving harmony between the space that existed and our intervention.
