Our neighbor works so fast building his addition, we said it must be elves doing. We joke but the truth is he is doing it all himself. We did get to help put in his 6 inch wide doors, they were heavy, just ask the spiders. Now he can put in the insulation and drywall in air condition comfort.He can work on the decking he has planned for the addition. He will need the help of his deck elves soon.
