Building Add-ons

A 20×30 outdoor garage with 9′ walls is a practical choice when you need secure vehicle storage without oversizing the footprint. This size works well on residential lots where space matters but enclosed protection is still the priority.

With 600 sq. ft of total space, the interior easily handles daily parking while leaving room along the walls for shelves, tools, or seasonal items. The single 9×8 roll-up door keeps vehicle access easy, and the front walk-in door makes it easy to step in without opening the garage. Two 24×36 windows bring in natural light from both sides, which helps when the building is used regularly instead not just for the storage purpose.

The vertical roof improves water runoff and reduces debris buildup, which matters over years of use. Fully enclosed steel walls add security and weather protection, while the Taupe wall color with Cocoa Brown roof keeps the building looking clean without constant upkeep.

This layout is best suited for parking-first use with light storage, rather than equipment-heavy work or tall vehicles. If you’re storing lifted trucks or planning overhead storage, a taller wall height would be worth considering.

All components including the doors, windows, colors, and layout — can be customized to fit your site and needs. If you’re unsure whether this size fits your vehicle or driveway setup, our team can help with that before ordering. Call building experts at Longstar to order your custom metal garage at direct factory prices.
