Gabarró collaborates with the ETSAV project for the construction of 2 outdoor classrooms

Students of the Master in Parametric Design in Architecture (MPDA) taught at the ETSAV build 2 outdoor wooden classrooms in 2 educational centres.

The COVID measures adopted during the past school year have motivated the creation of new teaching spaces that allow the extension of classrooms, beyond the security measures in times of pandemic, from the interiors of current school buildings to the adjacent outdoor spaces.

Semi-outdoor classrooms provide an ideal space for direct communication between people, without screens or other technological filters, in natural environments. On the other hand, they must configure meeting and teaching spaces in environments protected from solar radiation and ventilated.

Constructed classrooms are designed with digital tools that allow intensive use of geometry to reduce energy and weight of structures and are manufactured using numerically controlled machines that allow for fast, efficient, and prefabricated production.

The first structure, Zollinger, built in Can Cuní in Banyoles, is a shell made of WISA B-S / BB Birch Plywood, 18 mm WBP supplied by Gabarró and of metal angles.

The second structure, 3way, built at the ETSAV, is an ultra-thin reticular shell of WISA B-S / BB, WBP Birch Plywood pieces of 6.5 mm (widths and lengths) also supplied by Gabarró. The system is based on the tracing of 3 families of pseudo geodesic curves on a common surface, and that can be built from completely straight slats without any loss. The manufacturing technology is very simple and lies in the exact definition of the holes at the intersections. The MPDA program has allowed the optimization of the positioning of the curves.

In both cases, student groups followed a program of continuous reviews by international experts on structural design, wood construction, computational geometry, and membrane patterning. The students solved all the design, numerical fabrication and construction processes themselves.
