My 10yr old son will have his slotcar set and train set upstairs. Also a Checkpoint Porsche pinball machine, tanning bed, tv, etc...The barn will fill up fast with a 2 post lift, cabinets, and more cars.
Concrete was $3 per sq ft. 5000 psi, 5 1/2 inches thick with fiber mesh. 8 inches thick by overhead door. 4 1/2 inches thick with wire mesh outside. Total invested north of 110k. Thanks for all the compliments!
