I am a single mother of a 6 year old boy. I am on a low income budget and my son understands that. However, the only thing he asked Santa for Christmas was a clubhouse or playhouse to play in backyard. My dad said if I can get the materials and a floor plan, he would try to help me build one. Can you help me with a design or an idea, so I can give my son the Chirstmas he has been wanting all year. Thank you for your time.
