Design and build complex structures with a unique building system. Start by placing columns on an empty foundation. Connect them with beams to form a frame, then add walls and floors within. Add stairs to go higher, or rafters to place a roof. Cut openings in walls to place windows and doors.

Cobbwood is a freeform building system that operates much like a game. You control a character within a tiny virtual world, moving around to place the individual elements that form your structure, and tour your creation when you are done. There are rules for how elements can be placed, but there are no goals or deadlines beyond what you set for yourself. What you build is up to you.

For complex structures, planning is important. The floor plan editor allows you to design a layout with several layers, then provides chalk marks within the world to serve as placement guides.
