24 × 30: 720 square feet with room for a shop
A 24 × 30 building has 720 sq ft: a two-car garage plus about 6 ft of extra depth for a workbench, a mower and storage, or a small one-bedroom cottage. The perimeter is 108 ft. It works out to 1.65% of an acre, a figure that matters when a lot has a limit on how much of it buildings may cover.
Concrete for a 4 in floor is around 9.8 cubic yards with an allowance, about one full ready-mix truck, so plan for a crew: that much concrete has to be placed and finished before it sets. Painting the inside of 8 ft walls is 4.65 gallons for two coats over 813 sq ft. As finished floor area it is 792 sq ft of material, or 40 boxes of 20 sq ft.
