Sumit Singhal loves modern architecture. He comes from a family of builders who have built more than 20 projects in the last ten years near Delhi in India. He has recently started writing about the architectural projects that catch his imagination. Social Housing at Can Batlló in Spain by ESPINET / UBACH ARQUITECTES I ASSOCIATS S.L.P.January 15th, 2019 by Sumit Singhal
Article source: ESPINET / UBACH ARQUITECTES I ASSOCIATS S.L.P. The architecture studio Espinet / Ubach has completed a project consisting of 26 social housing units situated next to the emblematic old textile factory Can Batlló in Barcelona. A central courtyard is the driving element of the project, as it regulates the temperature of the building and acts as the epicentre of community life. The residential building of Can Batlló is the result of a public competition organized by the Municipal Patronat de l’Habitatge de Barcelona (PMHB). It is located on a residual site, bordering the former textile factory of Can Batlló (which has been classified as ‘of public interest’), in the heart of the Sants district. The plot has three sides that look out onto varying urban landscapes.  Image Courtesy © Pedro Pegenaute

Under the title ‘Opening Roads’, the competition presented the concept of a ‘wrapped’ structure of different heights, in accordance with local regulations on exterior and interior levels. This initial approach allowed us to explore the qualities of an interior courtyard, not only as a lighting and ventilation element, but also as an instrument of connection between the dwellings. The courtyard works as a climatic machine and has obtained very favourable results in the bioclimatic study of the building.

A ring of service areas has been placed around the courtyard, in the inner crown, and flexible living areas on the exterior facade. The ‘skin’ of the building adapts to each façade and produces optimal visual assembly. The result is the subtle fractures in the façade, the de-orthogonally of the envelope, and the break in geometric order of the dividing walls.

More than a mere passageway to the apartments, it becomes an oculus that opens towards the sky, attracting the light of night and day, winter and summer. It is both a conduit of the exterior environment and expels undesirable atmospheric conditions that are produced in the interior of the building, thanks to the current of air it generates.  Image Courtesy © Pedro Pegenaute  Image Courtesy © Pedro Pegenaute The building has a robust presence at street level. A porch shelters the entrance to the garage and enlarges the pedestrian access to the Can Batlló park. The treatment of facades reflects this intention; vivid white vertical perforations on the floors that accommodate the apartments and dark grey in the treatment of corrugated sheets on the ground floor. The building appears to ‘float’ thanks to this chromatic contrast.

All the perforations on the facade are vertical in character and in one, two, or three modules; depending on the interior space they serve. In all cases, their closure consists of a system of folding aluminium shutters, a constructive solution that ensures simple manoeuvring and solid closing.

The composition, located against the dividing wall, allows direct exit to the central courtyard, which also acts as a spatial distributor of the homes. El Patio The courtyard is fundamental piece of the structure of the building, acting as its thermal ‘chimney.’ This spatial structure acts likes a climatic engine that changes the heat (generated by solar infrareds), into an upward current of hot air, which counteracts with a cooler air from the environment. It uses natural energy as a driving force.  Image Courtesy © Pedro Pegenaute  Image Courtesy © Pedro Pegenaute The courtyard is also a place of social activities, foot traffic, games and visual stimulation. Its enclosures, which act as light and sight filters, are constructed with galvanized metal plates placed in parallel (orthogonal on the level of the hand railing.) On the first floor, the courtyard rests on soil, allowing a circle of vegetation fed by rainwater. The different regulatory heights of the façade allow interesting light inputs and a breakaway for the neighbourhood. They have avoided an excess of interior height.

All rooms enjoy natural, exterior light. The exception is the laundry that has interior light and ventilation. The layouts in each one is practically identical; with two or three bedrooms and integrated kitchens, separated spatially by a small service table.  Image Courtesy © Pedro Pegenaute  Image Courtesy © Pedro Pegenaute On the fifth floor, the configuration of volumes of the façade has allowed us to place two of the 4-bredroom duplex units of the three that exist in the project. The dividing wall is constituted as a separating element from the neighbouring building (it’s of a greater height) where we have situated the elevator motors, the installation room, and the opening of the staircase. A cat ladder leads to the highest point on the deck.  Image Courtesy © ESPINET / UBACH ARQUITECTES I ASSOCIATS S.L.P.  Image Courtesy © ESPINET / UBACH ARQUITECTES I ASSOCIATS S.L.P.
