The transformation was not only cheaper than demolishing and constructing a new building, it also used far less material, reduced the energy consumption of the building, gave the inhabitants more space, did not destroy the community, and turned something considered ugly into something beautiful.

Rainwater runoff is managed via two permeable basins in the park that enables the water to infiltrate the underlying soil and groundwater. The infrastructure mitigates urban flooding and promotes water awareness by showing the capabilities of basalt to enable natural water infiltration and the replenishment of groundwater.

Approaching completion: La Quebradora will filter 68 megaliters of runoff per year and filter an additional 32 megaliters of wastewater for use in a system of public toilets that serve those that, although having the facility, do not have water. The park will more than triple the number of trees in the area and increase the open space from 1 to 3 sqm per person.
