Emphasis was placed on block pressing to reduce waste, resulting in shapes developed accordingly. Additionally, postprocessing options were explored, leading to successful repressing of blocks solely from machining waste without binders. The team also devised a design algorithm for acoustic patterns, optimizing for both sound insulation and minimizing extraction from walls, thus reducing post-processing while maintaining superior acoustic performance. A developed web interface illustrates practical implementation. It guides users—architects to beginners—through designing homes on Barcelona rooftops, densifying the city. This versatile tool accommodates different sizes, shapes, and personalized designs with acoustic patterns and surface finishes, showcasing the system’s adaptability in urban settings.
