Use the existing shapes to create a build! You cannot add any exterior walls - but you can add interior walls and delete interior walls when merged! Get creative by moving them up a level or down to create a basement! #delibuildcrest #deligracy - this is my entry for Deli's building challenge, and I did my best to not use packs! this is supposed to be for 4 green-thumbed, hacking, musician, friends, but there is some bathroom sharing involved. please comment if anything is inaccessible!!
