Common Uses

What people build with a 30x45

1,350 square feet is enough to support a wide range of uses. Here are the four most common configurations our specialists see for the 30x45x10.

Residential 2-3 Car Garage

Park two full-size vehicles plus lawn equipment, bikes, and a workbench. Add a garage door opener and LED lighting package and this becomes your daily-driver garage.

Backyard Workshop

Ideal for woodworkers, hobbyists, and homeowners who need a dedicated shop separate from the house. Insulation and a walk-in door make it a comfortable year-round work space.

Household Storage

Keeps ATVs, kayaks, holiday decor, and seasonal gear locked up and out of the weather. 29-gauge walls and a 20-year Structural warranty protect what's inside.

Home Business / Hobby

Great for a side business, photography studio, or a detailing bay - the clear-span interior takes whatever layout you need without columns in the way.

Financing

Payment options on a 30x45

The 30x45x10 base package start in the low $16 Hundreds delivered and installed. Final price depends on height, gauge, colors, doors, insulation, and your state's engineering requirements - your specialist will build a firm, out-the-door number in one call.

30x45 metal building questions, answered

What's included with a standard 30x45 metal building from Keen's?
Every Keen's 30x45x10 enclosed building ships standard with (2) 10x10 roll-up doors, (1) 36-in. walk-in door, (2) 30x36 windows, a 14-gauge galvanized primary frame, 29-gauge roof and wall panels, and an A-frame vertical roof. Free delivery and free installation on your level site are included in the price, plus a 20-year Structural warranty on the frame.
How much does a 30x45 metal building cost?
A base 30x45x10 Keen's enclosed building starts in the low 16 hundreds installed. Final price depends on height, gauge, door and window count, color, insulation, and your state's wind/snow certification. Call 386-339-1676 for a same-day custom quote or use our online designer - we'll match your county's code and deliver a firm, installed price.
How long does delivery and installation take?
Lead time is typically 4-8 weeks from the day you reserve, depending on state, factory queue, and season. Installation on a prepared, level site usually takes 1-3 days for this footprint. Keen's has installed more than 75,000 buildings since 1999, and we schedule your crew, handle delivery, and anchor the building for you.
Do I need a concrete slab for a 30x45 metal building?
A concrete slab is recommended for most enclosed buildings this size, especially if you're parking vehicles, running a workshop, or bolting in equipment. Keen's can pour your slab as part of the project (rolled into your financing) - plan on roughly $6-$10 per square foot for a 4-inch reinforced slab depending on your region. We can also install on a gravel pad or directly to ground with mobile-home anchors for equipment storage.
Do I need a permit for a 30x45 metal building?
Most counties require a permit for an enclosed building of this size. Keen's will provide engineered drawings, wind/snow certifications, and foundation specs sized to your county - this is usually all a building department needs. Your Keen's specialist will walk you through the local process, and our state landing pages cover permitting nuances for your area.
What is a 30x45 metal building best used for?
A 30x45 gives you 1,350 square feet of clear-span space and 13,500 cubic feet of enclosed volume. It's a 2-car garage with a dedicated 20-ft rear bay for a workbench, lift, or lawn care equipment. With custom door, window, and height options you can adapt the same shell into a garage, workshop, barn, warehouse, or agricultural shelter.
Can I customize a 30x45 metal building?
Yes - you can upsize doors up to 14x14, add garage door openers, add windows, raise the side walls from 10 ft to 16 ft, add lean-tos, upgrade gauge, and add insulation. Color-match your roof, walls, and trim from 15 standard brand colors. Use our online designer or call 386-339-1676 - we'll walk you through the configuration.
