Barcelona City Council chose the construction proposal submitted by Sorigué’s city utility company, Constraula, in partnership with the Polytechnic University of Catalonia (UPC)
, as one of the three winners of the urban challenge launched to improve the livability, comfort and energy performance of the city’s apartment buildings.
As part of this challenge, launched by the BIT Hábitat Foundation with the support of the Municipal Institute of Planning and the Department of Planning, over the course of one year Barcelona will test the three winning prefabricated construction prototypes to sustainably expand its apartment buildings.
The proposals selected are metal or wood structures added on to new building façades. This also frees up space for the homes in terms of balconies or community areas, or for adding an elevator, improving insulation and sunlight. In addition, these can placed on rooftops for adding solar panels, green roofs or reusing rain water.
Sorigué’s proposal is regenerating Barcelona
The business group’s proposal, called Regenerating Barcelona (Regenerar Barcelona), relies on a self-supporting wooden structure that moulds to a building's façade to design interior and exterior spaces.
Its goal is to enhance the living conditions, exterior appearance and energy performance of apartment buildings.
The prototype was designed together by Constraula and UPC research groups: REARQ – Architectural Refurbishment and Restoration and GICITED – Interdisciplinary Group of Building Science and Technology.
