Badonk - My 02.
I think you are doing this all wrong after looking at the shop and this new build. You said you are keeping the old shop. So you don't need another one. So don't make another one. One shop is enough.
Pick a shop... any... shop but just have one. Looks to me like you are storing cars in the old shop - but don't have enough room in the shop to do shop stuff with all the cars in there. So you have to shuffle cars to do shop stuff - no room in the shop cuz its full of cars. 2 post lifts are for shop stuff not storage. If keeping the shop and tools then treat it as such...all cars to the mountains, unless it is in rotation for work in the shop. Plus your current shop is setup to be productive.
The new build is a storage place - current shop is a work place. Why blast or ******** work on projects in the new space? It dilutes the functionality, just treat it for what it is - a showroom if you will. That way you can pick and choose what gets rotated in and out for projects but always have a clean space for the showroom. 4 cars, snowmobiles, motorcycles, maybe more cars...plus you need a go kart for that driveway.
You got tools at the old shop, you got tools (new) at the new build...do I need this tool at this shop or did I bring the parts from that shop - but why? Your old shop will be empty of cars - tons of room to work so keep all functionality there.
Too much stuff - and you ain't getting any younger old man so time to consolidate. I know you won't do that so - use the new build to store the fruits of your labor and results of your projects bust a grind at the old shop where you make dust and get dirty.
Have coffee in the morning and bourbon in the evening strolling through the showroom looking at the mountains and enjoy - take one out for a spin, setup a wash and detail bay, check tire pressures - that is about as dirty as I would get in there.
I would be worrying about where the artwork and big screen would go in terms of layout for Sunday F1 and football while polishing the cars vs. the blast cabinet. You already setup up the compressor at the old shop - def don't need two.
Could be a mix of cars and a 3D-Design studio? - clean projects.
Again just my 02. Please make sure there is enough storage room though in the showroom for another GSA. I want my bike to stay clean.
