Welcome to my first shell challenge! Place this shell on a 40x30 lot or bigger and make your own house with it. You can only use Expansion Packs, and you're not allowed to touch the walls I made. Upload your build until October 31 using #lineashellchallenge to make chance to win a pack of your choice.
