I want to create a shell for anyone to build off of. Here are the rules: you can not extend the exterior shell or add on to it. You can do whatever you want inside but you can't modify the exterior shell. Feel free to have fun with the landscaping but no additonal builds outside of the main shell. A smaller lot is recommended. hashtag #nardshell so I can see your builds. #shell #shellchallenge #nardvillain
