This project studies the aggregation of a designed standard masonry element. Emphasis was placed on the unit’s ability to intersect with its neighbors and to stack without the use of mortar. Three simple units consisting of a quare with tabs and sockets in various positions allowed for simple mass production and experimentation. Following this initial step, many experiments were conducted to understand the surface-making potential of the units themselves. Finally, focusing on a bottom-up approach, the aggregation properties of the units themselves dictate the form of the resulting enclosure.
