That's true for aluminum tanks, but it's not true for Carbon Fiber tanks, which SpaceX is rumored to be considering for the BFR. Having a larger diameter first stage has a bunch of advantages: It would make the rocket shorter, which would make it easier to work with.
Bigger Is Better. Garages are used as workshops, parking spots, laundry rooms and for storing all those things you wish you would have never bought. With so many uses, it's important to allow plenty of space. Two-car garages are typically at least 18 feet wide by 22 feet deep. This allows room for two 9-foot garage doors and for cars to pull in completely. Of course, if you don't plan on parking a car in your garage, you may opt for a smaller structure.
One plan for a two-car garage provides 24â² x 24â² (576 SF) on the first level and includes a loft with 300 square feet of space accessible with a drop down ladder. Expand to 26â² x 28â² (728 SF) and include full stairs to a 380 SF storage, workshop, or office space.he size you choose will be the major factor in overall cost. The minimum size for a single-car garage is about 12â² x 20â² (240 SF). A two-car garage minimum structure is about 20â² x 20â² (400 SF). A 3-car minimum is 32â² x 24â² (768 SF).
