Shell challenge series! Here's the first of five that I will be creating. Rules are the same as most other challenges, do not change what exists already on the lot. Do not delete or change existing roof pieces, platforms, halfwalls. Add interior walls, but do not delete any already placed. Add balconies, platforms, rotate lot, adjust wall height, etc. Have fun and happy puzzling! #shellchallenge #shellseries #cynzushellseries #buildchallenge
