A Compact Garage for Everyday Storage

The 20′ × 24′ post-frame garage gives you 480 square feet in a compact rectangular footprint. It provides usable space for a vehicle, lawn equipment, household storage, and small projects without overwhelming the property. The open floor area leaves flexibility for shelving or a modest work area, so the same building can support everyday storage and occasional hands-on work.

Choose the Wall Height That Fits Your Plans

The 20' × 24' garage is available with 10', 12', 14', or 16' wall heights. A 10' building is a practical starting point for common residential storage, while taller options provide additional clearance and flexibility. Door size, equipment clearance, and future interior plans should be reviewed with Keystone before the final design is approved.

Make the Garage Your Own

The 20' × 24' plan is a starting point. Talk with Keystone about exterior colors, door and window placement, additional openings, overhangs, porches, concrete, and other available options. Custom features can affect pricing, engineering, and construction time and should be confirmed in the project-specific quote.
