Industrial designer Octavio Barrera hails from Spain's Canary Islands, where this project was executed. Barrera was hired to design a full complement of furniture—benches, tables, shelves, etc.—for the offices of the Rayuela Association, a community organization in Tenerife.

To keep things affordable, Barrera designed everything out of plywood, all with straight cuts and unfinished edges. These pieces would be too lightweight to reliably stand on their own. Thus for ballast he specified Canary Island concrete block, the region's version of CMUs, which are made using local volcanic rock:

"The project is divided into two formats: firstly, interventions that facilitated a new organization of the space, such as a meeting room and video call booths; secondly, a modular system for furnishing the space, from tables to partitions and planters, all based on the same design principles. They were designed with the idea of ​​creating a visual language that would integrate all the pieces with their surroundings."

"All the pieces and modules were constructed with the same materials, and as a subtle nod to the original design, the Canary Island block was used to add weight to certain lightweight structures and create a visual harmony that connects the whole."
