How Big Would A House On The Moon Need To Be To See It From Earth?

In the future some of us will be living on the moon. Or maybe not! We just have to wait and see. But if we could build a house on the moon, could you see it from Earth? And how big would our Moon home need to be for someone standing on Earth to see it with the naked eye?
