Plan Dedicated Areas for Larger Storage Needs

The 40′ × 80′ post-frame garage is the largest featured option, with 3,200 square feet across a broad, extended footprint. That combination of width and depth gives you room to plan dedicated areas for equipment, vehicles, supplies, inventory, and long-term projects. Organizing those uses into separate zones can make a large building easier to navigate and keep frequently needed items accessible.

Equipment and implement storage
Vehicle and trailer storage
Long-term project areas
Inventory or business storage where permitted

Discuss the access and clearance your intended use requires with Keystone before finalizing the design.

Choose the Wall Height That Fits Your Plans

The 40' × 80' 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 40' × 80' 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.
