The rules are simple!! DONT TOUCH MY WALLS!! You can change wall height, add plattforms, roof, patio, balcony etc but you cant add walls OUTSIDE or change them. A garden is optional. You can freely rotate and place the house on the lot where you want. You can use all packs! Be creative and original!! Have fun and good luck creating!! :D Use #neoyon1 so I can find, like and comment your build!!! #shellchallenge #shell #fun #challenge
