16 × 24: cabin, garage or studio at 384 square feet

A 16 × 24 footprint is 384 sq ft. It is a classic small-cabin and large-shed size partly because 24 ft is exactly three 8 ft sheets of plywood end to end, so the sheathing goes on with little cutting. It also makes a roomy single garage with a shop along one side, or a detached studio. The outline is 80 ft around and 28.8 ft corner to corner, which is the check for square when you set the forms.

A 4 in slab under it runs to about 5.2 cubic yards with a little spare, a comfortable single truckload. Finished inside, expect 22 boxes of flooring, and for 8 ft walls 3.37 gallons of paint for two coats on 589 sq ft, which is more economical in a 5 gallon pail (by the can it is 3 gallons + 2 quarts).
