building a shop

[zen]

so what would you consider essentials in building a home workshop? some parameters:

1. i'm building a new freestanding garage. probably two car or oversized one car depending on cost and available funds.
2. assume basic wrenches and etc are already covered. also have air compressor and related tools already.
3. i possibly have access to a 12' lift for a good price.
4. primary purpose is for regular maintenance of several cars and working on one project car at a time. mostly the maintenance side though.

so what are the things to target?

• minimum amount of space around the car for work room (i know get the most possible, but what would you consider a minimum including workbench space etc.
• shop essentials like utility sink (which means i have to run plumbing), power placement, lighting, allow small room for painting/powerdercoating, oven...
• and any other considerations in making it "shop friendly".

budget is pretty limited. i am guessing (this is before even having talked with an architect) that i will have $15-$20k to spend and have to have the garage look like belongs with the house (HOA) so have to do stucco. so i have to cover garage and tools with that money.
