A larger storage shed should also make sense at the entrance, especially when a garden path or planting area is nearby. The Best Barns Shedquarters 12x20 Shed Kit with Sliding Doors gives homeowners a dedicated place for garden supplies, seasonal belongings, and outdoor gear, with doors that slide instead of swinging outward. Its long layout and tall side walls let you plan storage across the building and upward, while the primed siding leaves the exterior color up to you.
Benefits
Room to organize by use: The nominal 12'x20' size gives you a substantial building for planning separate areas for gardening supplies, project materials, and seasonal storage. You can arrange frequently used belongings nearer the entrance and reserve space farther back for items used less often.
An entrance without an outward door swing: Two sliding doors run on interior pocket tracks at the center of the gable end, so opening them does not require a swinging arc outside. This helps when planning the approach from a nearby path or garden area. Keep the interior door travel areas clear when arranging storage.
Height that supports your storage plan: The 8'1" side walls give you vertical space to consider for your own shelving and hanging storage. Planning upward can help you organize smaller supplies above lower storage areas while leaving room below for larger belongings.
An exterior color you choose: The LP SmartSide siding comes primed and ready for paint, allowing you to coordinate the shed with your home, fence, or other backyard structures. Paint is purchased separately, so you can select the finish as part of your project.
Prepared materials to start your build: Precision pre-cut components reduce some of the measuring and material preparation involved in building from raw lumber. The kit provides the structural components, sliding doors, track, and assembly hardware to work from, while some on-site cutting remains part of the build.

Don't Take Our Word For it! Here's What Our Customers Think:
Hats off to Homestead Supplier for superior customer service - these guys go above and beyond to answer all my questions. We purchased the Beach House shed for some extra storage but ended up using it as a backyard playhouse for the kids :). Now we have to buy another shed lol... The shed is great, sturdy, and would recommend to others.
- Sam B.
I found the buying experience to be far better than expected. Very easy to order, received immediate order confirmation, excellent customer service, order showed earlier than expected and in excellent condition. Would definitely recommend
- Dean G.
After 7 months of waiting for our pool to be completed, we are thrilled to have gotten our new shed built. It perfectly completes our backyard renovation. We love it! The instructions were clear, and the building is sturdy. We’ve had a number of inquiries about who we bought our shed kit from.
