Frequent passerby in the neighborhood of Santa Margarita, Spain may find themselves a bit lost when they can't seem to find the white wall they just passed by. Appearing at first as a simple sheet of folded paper, this beautiful white-walled building features a facade of panels that open in brilliant pops of color. Designed by Romera y Ruiz Arquitectos, "Ocho casas inscritas y tres patios" is a sustainably constructed social housing complex with a facade that changes according to the wishes of its inhabitants!
