20×13 FT Metal Sheds
Twenty by thirteen feet is garage scale: roughly 237 inches wide, 152 inches deep and 100 inches tall, close to 250 square feet with a ridge high enough to stand under anywhere in the building. This is the size that takes a car, a trailer, a mower and a workshop corner at the same time.
Units this large are shipped as a multi-package flat-pack and are usually installed on a concrete slab by a two or three person crew over a weekend. Budget for the slab as part of the project — at 250 square feet it is a significant part of the total cost — and confirm delivery access, because the cartons are long and heavy and will not go through a side gate. Check with your municipality as well: at this size a permit is normally required.
