30x48 my origional plan was to split it with half workshop and half barn, and the lift at the overhead doors. We had our house and barn put up at the same time(the house is a 4 box modular). The barn was supposed to have 2 raised trusses at the overhead door, but they were never put in, since I didn't have the lift and was running out of money it didnt matter.
4 years later when I put in the lift I decided to put in inline with the sliding door 90 degrees to the trusses and have since modified one truss so I can raise my Pickup so I can stand under it, so it worked out for the better that the barn people left out the raised trusses I origionally wanted. I can have a car on the lift and still pull into my work area with another altho it is close.
I will say it again the lift is the best $2000 you can spend on tools if you do your own work.
My Ideal house is a 2 bedroom apartment on top of a 4 bay shop, my wife dosen't agree though.
