I have just had a fire at the shop I have rented for over 20 years and am in the planning stage of a shop attached to my home. I have been a carpenter wood worker cabinet maker for nearly 45 years and a back yard mechanic for longer than that. At this point I am considering an over under situation mechanics below with 12' ceilings and woodworking shop above. I am well aware of the space I need for the wood working area but undecided on the footage needed for the mechanics shop. What I am thinking is 24' x 32' x 12' for the work area which will contain a lift as well as all other basic tools. auto storage will be in a another building. So my ultimate question is given a 24' width building what depth would you go?
