Check out how the walls of a decrepit slaughterhouse in Madrid have been rebuilt using recycled roof shingles. Originally built in the 1920s, the building's roof in particular needed a serious upgrade. When it was replaced, stacks of some perfectly good clay tiles were left behind. Arturo Franco Architects saw opportunity in this waste pile and decided to use it to rebuild the interior walls. While the exterior was left largely unchanged, the stacked clay interior has been transformed into an inspriring, avant garde office, stockroom and event space.
Figuring out how to stock and bond the tiles so that they could be used as an interior building material required a lot of thought. It was also important to manage their weight, but the designers prevailed in the end thanks to their ingenuity. Laid on top of one another, the tiles make hollow bricks that create a harmonious acoustical environment.
While most of the walls are comprised of shingles stacked on top of one another, certain portions were left unstacked, allowing natural lighting to permeate the dark building. This configuration also creates optimum thermal massing so that the building won’t require too much energy to maintain a comfortable temperature. The original architect, Luis Bellido, would no doubt be proud to see the tiles that are no longer great for roofing put to such spectacular re-use.
