A small place the Sant Gervasi neighbourhood is the space chosen by the customers - a couple - to enable it as a dance and music studio. The premises, in a building from the beginning of the 20th century, is a cube enclosed between buildings, with two free levels: the façade on Ballester Street and the roof. The latter is also the terrace of the homes in the same building. Over the years, this space has been successively taken up by craft workshops, small industries and shops, suffering very aggressive interventions that completely hid its original state. After removing all the superfluous, we find a diaphanous, double-height box, with light entering at two ends, one zenithal and the other one on the façade, and with a single element that presides over the space: a pillar of two wooden shafts that collect the rafters of the roof. The addition of a mezzanine responds to the program (which required more surface area): rooms of various sizes and qualities for dance or music and of flexible use, as well as annexes. Without renouncing the possibility of being able to continue having the overall reading of the space, we decided to place this piece looking for volume and light to flow from one side to the other. The loft is understood as an individual and self-supporting element. Its structure, exempt from the rest of the building, has its starting point in the double wooden pillar and from this point it expands isotropically, creating a structural grid of three equal spans. You go up to the upper floor through a wooden piece of furniture that has the double function of container and ladder. You enter the premises through a first double-height space and after passing under the area compressed by the loft, the space gains height again and expands towards the skylight. The loft is wrapped around two double-height spaces, the spaces through which light enters, filling all the corners. The different glass divisions also allow a visual continuity of the space both on the lower and upper level, as well as a precise placement of some wall mirrors that multiply the volume by creating unexpected geometries. The place is a closed space; the openings in the façade are very high, and the skylight barely allow views to the outside. However, because of its large openings and good orientation (south-east façade), the cycle of natural light is lived intensely inside and gradually melts with the artificial light throughout the day. The few materials used have been chosen with great rigour and intention. At the entrance level we find continuous microcement flooring in the passage areas and pine flooring in the great room. The linoleum flooring, which starts on the staircase and on the entire mezzanine floor, takes us through the rooms on this level. Both in the large room on the ground floor, and in the two smaller rooms on the upper level, the ceiling is finished in Heraklith to achieve acoustic and environmental comfort.
