Choose the Wall Height That Fits Your Plans

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 30' × 40' 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.
