SIFERA House is based on the concept of pre-design where the project is worked on jointly with the manufacturers from the initial phases. The manufacturers develop a construction system for SIFERA based on pre-industrialization, pre-assembly and the use of easily recyclable materials. The dwelling is to be built and operable in under two months. The structure is made of large laminated wood panels with the sustainability seal FSC. The envelope and interior finishes, like base molding, furniture, etc. have been pre-assembled in a workshop to be mounted on site in a maximum of fifteen days per system.

The Rambla Catalunya is the nexus avenue of connection and growth of l’Aldea. Parallel to this avenue is the Ayuntamiento Street, the station and the various public spaces like the Via Verde hiking trail, that generates a second umbilical cord for the site. Various roads that lead to the Delta cross this axis, like the Ligallo carvallo Street. The roads, or ligallos, are circulation axes that define a spatial fabric of farms of the Ebro River delta. The site is located at the junction of one of the ligallos road and a new street, product of the current urban planning. At this point, two spatial fabrics are superimposed, the traditional fabric of the rice farms and the fabric of urban abstraction.
