  This paper presents a method for generating floor plans for structures in
Minecraft (Mojang 2009). Given a 3D space, it will auto-generate a building to
fill that space using a combination of constrained growth and cellular
automata. The result is a series of organic-looking buildings complete with
rooms, windows, and doors connecting them. The method is applied to the
Generative Design in Minecraft (GDMC) competition to auto-generate buildings in
Minecraft, and the results are discussed.
