This is a tough question to answer. Right now I am using my basement as a workshop for the work being done around my house. It is 18x30. I have found myself working on the back patio a bit this summer which is an additional 12x13. My permanent shop will be in my one car garage The back work area is a measly 6x12ish. With the car out, it grows to 24x12. I am also building a 10x14 shed in the back yard which may serve as a workshop of some sort.
