Best 12×20 Metal Building Kits for Storage, Vehicles, and Backyard Workshops
The best 12×20 metal building kit depends on whether you need enclosed storage, vehicle access, or a more open shelter. The VanAcc, Devoko, and SHPAI options are closest to the requested footprint; the K Knowbody 13×20 is a slightly larger alternative with a floor base kit. Backyard Discovery is a wood carport with a steel roof, not a metal building kit, but may suit buyers comparing covered outdoor structures.
| Product | Best For | Key Difference |
|---|---|---|
| VanAcc 12×20 Shed | Storage and workshop use | Transparent panels, windows, and vents |
| Devoko 12×20 Shed | Vehicles and flexible access | Three doors and windows |
| SHPAI 12×20 Carport | Drive-in storage | Front and side doors |
| K Knowbody 13×20 Shed | More floor area | Galvanized floor base system |
| Backyard Discovery Norwood | Open-sided coverage | Cedar structure with steel roof |
VanAcc 12×20 Shed With Windows
Best for: Buyers who want an enclosed 12×20 space for yard equipment, seasonal storage, or a backyard workshop. The listed dimensions are 12 by 20.2 feet, making it a close match for the requested footprint.
Two transparent panels and four side windows bring daylight into the shed. Four vent windows are intended to improve airflow, while wide double doors help with moving larger items in and out. The doors have a lockable design.
Why it was selected: It combines a near-12×20 footprint with light, ventilation, and access features useful for storage or projects. Limitation: The supplied product details do not specify a floor or foundation system, so confirm what the package includes before planning installation.
Devoko 12×20 Shed With Three Doors
Best for: Buyers who need an enclosed metal structure for vehicle or equipment storage and value separate walk-in access. The product description presents it as a combined carport and tool-shed option.
Its listed layout includes main doors and a side door, both with lockable latches. Windows and built-in vents are described as supporting airflow and a brighter interior. The metal construction has a UV-resistant surface coating, according to the product information.
Why it was selected: The 12×20 size and multiple access points make it a direct match for buyers comparing enclosed storage layouts. Limitation: The provided details do not give specific panel gauges, foundation requirements, or weather-load ratings, so check those specifications before purchase.
SHPAI 12×20 Metal Carport Garage
Best for: Buyers seeking a 12×20 structure for a vehicle, lawn equipment, or bulky outdoor items. The product is described as a metal carport and garage with front and side access.
SHPAI lists UV resistance, rust resistance, moisture protection, reinforced roof beams, and a higher roof intended to make entry more convenient. Front and side doors support drive-in and walk-in access. The listing also describes the doors as lockable.
Why it was selected: Its stated footprint and dual-door arrangement address common vehicle-storage needs. Limitation: The supplied features do not provide a specific roof-load rating or the exact foundation and anchoring requirements. Verify these details for your location and planned use.
K Knowbody 13×20 Shed With Base
Best for: Buyers who can use a little more width than a 12×20 building offers and want a floor-support system included. This metal garage shed measures 13 by 20 feet and has an 8-foot peak height.
The galvanized steel base system creates separation between the structure and the ground and includes ventilation channels. The listing states 250 pounds per square foot of support for lawn equipment. Wide-swinging double doors are described as providing access for vehicles and equipment.
Why it was selected: It is a close size alternative with a clearly described base-floor system. Limitation: It is 13 feet wide, not 12. The product information recommends a concrete foundation and included anchors; soft surfaces may require separately purchased heavy-duty auger anchors.
Backyard Discovery Norwood Carport
Best for: Buyers comparing open-sided covered parking or outdoor living structures rather than an enclosed metal building. The Norwood measures 20 by 12 feet, but its structure is cedar wood with a hard-top steel roof.
Listed features include a PowerPort with three electrical outlets and three USB ports; a power source is not included. The product description states that the structure is tested for up to 12,600 pounds or 30 inches of snow and winds up to 100 mph, and it lists a five-year warranty.
Why it was selected: Its footprint matches the 12×20 search, and the steel roof makes it a relevant covered-structure comparison. Limitation: It is not an all-metal enclosed shed and does not provide the same locked storage arrangement as the metal shed options.
Buying Guide: How To Choose A 12×20 Metal Building Kit
Do you need an enclosed shed or a carport?
Choose an enclosed shed if you want walls, doors, and a more defined space for tools or stored belongings. A carport may suit vehicle coverage when open access matters more than enclosed storage. Check the listing carefully: terms such as “garage” and “carport” do not always mean the structure has the same wall and door configuration.
Which size and access layout fit your use?
Measure the available site and the items that need to pass through the doors. A 12×20 footprint is not interchangeable with a 13×20 model if width is limited. For vehicles or large equipment, compare door placement and opening dimensions; the supplied details do not state exact clearances for every product.
What should you check about the base and anchoring?
Confirm whether a floor or base frame is included, and plan a level foundation suited to the product instructions and site. The K Knowbody 13×20 listing specifically recommends a concrete foundation and anchors. Its guidance also calls for separate heavy-duty auger anchors when installing on soft ground. Do not assume another kit uses the same anchoring system.
How important are windows and ventilation?
Windows and transparent panels can increase natural light, while vents can help support airflow. These features may be useful in a workshop or frequently accessed storage shed. They do not replace checking the manufacturer’s guidance for moisture management and safe storage of specific equipment or materials.
Frequently Asked Questions
What is the closest match to a 12×20 metal building kit?
The VanAcc, Devoko, and SHPAI products are listed as 12×20 or approximately 12×20 structures. Compare their door layouts and included components before choosing.
Is a 13×20 shed a suitable alternative?
It may be suitable if the extra width fits your site. The K Knowbody option is one foot wider than a 12×20 footprint and includes a galvanized base system.
Does every option include a floor?
No. The provided product information specifically describes a galvanized base or floor system for the K Knowbody 13×20 model. Check the package details for other products.
Can a 12×20 shed be used as a workshop?
The VanAcc and Devoko descriptions identify workshop use as a possible application. Check the actual interior layout, access, foundation needs, and product instructions for your intended setup.
Is the Backyard Discovery Norwood a metal building?
No. It is a cedar pavilion or carport with a hard-top steel roof, so it is an open-sided alternative rather than an all-metal enclosed building.
