Key Features & Specifications

Standout Features
This shed kit isn’t just about providing space; it’s built with features aimed at durability and a finished look.
- 50-Year Siding Warranty: The most prominent feature. This isn’t a prorated warranty; it’s a robust statement about the quality of the engineered wood siding used, which is primed and ready for paint.
- All Pre-Cut & Pre-Drilled Lumber: Every piece of framing and siding is precision-cut and pre-drilled for fasteners. This drastically reduces cutting errors and speeds up assembly for those wondering about the Belmont shed pros and cons related to construction.
- Heavy-Duty Floor Frame System: Features 4×4 pressure-treated skids and 2×6 floor joists spaced 16″ on center, providing a solid base capable of supporting significant weight.
- Full-Size Double Doors: The doors are a full 7 feet tall and wide enough for easy access with riding mowers, ATVs, or large equipment, a major pro for practical use.
- High-Quality Materials: Made from kiln-dried, premium wood. The use of quality materials throughout is a core part of the Best Barns Belmont honest opinion—it feels substantial, not flimsy.
- Ample Ventilation: Includes gable vents to promote air circulation, reducing moisture buildup and protecting your stored items.
- Cottage-Style Design: The sloped roof and overall design are more aesthetically pleasing than a basic box, adding value to your property.

What’s Included in the Box

Upon delivery, you’ll receive multiple heavy bundles containing all the major components for the Belmont. The packaging is industrial-grade, designed to protect the pre-cut lumber during shipping. The contents are meticulously organized by build phase: one bundle contains all the pressure-treated wood for the floor frame and skids, another has the wall framing, another the roof trusses, and separate bundles for the primed siding and roofing materials. All necessary nails, screws, and hardware are included in clearly labeled bags. The instructions are a detailed, step-by-step manual with clear diagrams. Our first impression was the sheer weight and quality of the wood—it’s immediately apparent this isn’t a lightweight, big-box store kit. Everything you need to build the shell is in the box. However, note that the foundation materials (concrete blocks, gravel, etc.), paint for the siding, and shingles for the roof are NOT included. This is a critical point in any Best Barns Belmont honest opinion; your total project cost will be higher than the kit price.
How to Use Belmont 12 ft. x 20 ft. Wood Storage Shed Kit: Complete Guide

Step 1: Site Preparation & Foundation
This is the most critical step not covered in the kit. Choose a level, well-drained area. Most owners use a gravel base or concrete piers. We recommend laying a perimeter of solid concrete blocks, ensuring they are perfectly level. This foundation will support the 4×4 pressure-treated skids included in the kit. A proper base is non-negotiable for the structure’s longevity and is the first real test of whether the Best Barns shed is worth buying for your skill level.
Step 2: Floor Frame Assembly
Following the manual, assemble the 2×6 floor joists onto the 4×4 skids. All pieces are pre-cut, and the pre-drilled holes align perfectly. Use the provided galvanized nails and screws. This stage goes quickly and gives you a solid platform to work on. Having a power drill/driver and a hammer is essential.
Step 3: Wall Framing & Sheathing
Construct the four wall frames on the ground using the pre-cut studs and plates. The pre-drilling is a huge time-saver here. Once each wall is assembled, you’ll attach the primed siding panels directly to the frame before raising it. This “pre-sheathing” method is a smart design that adds rigidity and simplifies the raising process.
Step 4: Raising Walls & Installing Roof Trusses
With a helper (or two), carefully raise each wall into place on the floor frame and secure them together at the corners. Then, install the pre-built roof trusses. This is where the structure truly takes shape. The manual’s sequencing here is logical and safe.
Step 5: Installing Roofing & Finishing
Apply the roof sheathing (included), then your choice of shingles (not included). Install the trim, fascia, and doors. Finally, paint the primed siding with a high-quality exterior paint to activate the 50-year warranty. For a smooth process, consider using a paint sprayer for large projects.
Step 6: Maintenance and Care
Once built, maintenance is minimal. Periodically check the paint finish for any chips and touch up as needed to protect the wood. Ensure the roof is clear of debris and that the door hinges remain lubricated. For more detailed care tips, see our guide on Maintaining Wooden Outbuildings.
Performance & Real-World Testing

Testing Methodology
We assembled the Belmont over two weekends with a team of two moderately experienced DIYers. We tracked total labor hours, tool requirements, and noted any challenges. After assembly, we monitored the shed’s performance over three months through varying weather conditions, including heavy rain and strong winds, to assess its durability and weather resistance.
Performance Metrics
Build Time & Effort: Total hands-on time was approximately 25-30 hours, not including site prep and painting. The pre-cut lumber saved hours of measuring and cutting. The instructions were generally clear, though some steps required careful reading.
Structural Integrity: Once complete, the shed is remarkably solid. There is zero flex in the floor, and the walls are rigid. The double doors swing smoothly without sagging.
Weather Resistance: After sealing the siding with paint, the shed proved completely weathertight. No leaks were observed during heavy downpours, and the ventilation prevented interior condensation.
Real-World Scenarios
We used the shed to store a riding mower, garden tiller, bicycles, a workbench, and numerous tools. The 240 sq. ft. space is vast and well-organized. The double doors allowed easy drive-in access for the mower. The high-quality wood and sturdy construction gave us confidence in storing expensive equipment, which is a core part of determining if the Best Barns Belmont shed is worth it.
Claims vs. Reality
Best Barns claims of “highest quality wood” and a “straightforward” assembly hold true in our experience. The 50-year warranty is a powerful claim that, while we can’t test over decades, is backed by the evident quality of the thick, primed siding panels. The claim that it’s “pre-cut and pre-drilled” is absolutely accurate and is the kit’s greatest advantage.
Pros and Cons
What We Loved (Pros)
- Unmatched Warranty: The 50-year siding warranty is a game-changer, offering incredible long-term peace of mind.
- Superior Build Quality: The materials are heavy-duty and feel premium. This shed is built to last for decades.
- Pre-Cut/Pre-Drilled Design: Drastically reduces complexity, errors, and the need for advanced woodworking tools.
- Spacious & Functional Design: 240 sq. ft. with full-size doors makes it incredibly versatile for storage, workshops, or more.
- Aesthetic Appeal: The cottage style looks like a permanent, attractive outbuilding, not an afterthought.
What Could Be Improved (Cons)
- High Initial Cost: At over $6,600 for the kit alone (plus foundation and finishing costs), it’s a major investment.
- Significant Assembly Labor: Requires 2-3 people and a full weekend or two. It’s not a quick afternoon project.
- Missing Key Components: Foundation materials, roofing shingles, and paint are extra, adding substantially to the final cost.
Balancing these Belmont shed pros and cons is essential for your decision.
Belmont 12 ft. x 20 ft. Wood Storage Shed Kit vs. Competitors
How does it stack up against other options? Let’s compare it to a typical big-box store resin shed and a higher-end metal building kit.
| Feature | Best Barns Belmont (Wood) | Big-Box Resin Shed | Premium Metal Garage Kit |
|---|---|---|---|
| Material | Premium Wood | Plastic/Resin | Galvanized Steel |
| Durability | Excellent (50-Yr Warranty) | Good (UV can degrade) | Excellent (Rust-resistant) |
| Aesthetics | Best (Traditional Look) | Fair (Plastic look) | Industrial |
| Assembly | Complex DIY | Moderate DIY | Very Complex (Often pro-installed) |
| Price Point | $$$$ (High) | $ (Low) | $$$$$ (Very High) |
| Insulation Potential | Easy | Poor | Difficult |
When to Choose This Product
Choose the Belmont if you value a traditional wood aesthetic, supreme durability with a stellar warranty, and have the DIY skills (and friends) to tackle the build. It’s ideal for a permanent, attractive addition to your property.
When to Consider Alternatives
Consider a resin shed for basic, low-cost seasonal storage. Look at a metal building if your primary need is maximum clear-span interior space and you’re hiring professionals. For a broader Belmont 12×20 shed vs alternatives analysis, read our comprehensive material comparison.
Who Should Buy Belmont 12 ft. x 20 ft. Wood Storage Shed Kit?
Ideal For:
- The Serious DIY Homeowner: Someone with intermediate skills, tools, and a couple of willing helpers who wants a pro-grade result.
- Owners Needing Long-Term, Secure Storage: If you’re storing valuable tools, equipment, or vehicles and want a structure that will protect them for 20+ years.
- Property Owners Wanting Curb Appeal: If you want a shed that enhances your property’s look, not detracts from it.
Not Recommended For:
- First-Time DIYers or Solo Builders: The scale and complexity are daunting for one person or a novice.
- Budget-Conscious Shoppers: The total all-in cost is high. If your budget is tight, a smaller or different material shed is a better fit.
- Those Needing Immediate Storage: If you need a shed up in a day, this is not the kit. It’s a project.
Expert Tips for Maximum Value
Tip #1: Invest in a Perfect Foundation
Don’t skimp here. A level, stable base of gravel or concrete blocks is critical. Time spent perfecting the foundation will make every subsequent step easier and ensure the doors operate correctly for years.
Tip #2: Organize & Label Parts
As you open bundles, sort lumber by size and label them with painter’s tape according to the manual (e.g., “Wall Stud – 92.5″”). This saves countless hours of searching later.
Tip #3: Use Quality Exterior Paint
To activate the 50-year warranty, you must paint the primed siding. Use a premium 100% acrylic latex exterior paint. For best results, a high-volume low-pressure (HVLP) sprayer will give a smooth, professional finish much faster than brushing.
Tip #4: Pre-Assemble Doors on a Flat Surface
Assemble the double doors on a flat garage floor or driveway before hanging them. This ensures they are square and makes installing the hinges and hardware much simpler.
Tip #5: Add Lighting & Electricity During Build
If you ever think you’ll want interior light or outlets, run conduit and wires under the floor or through the walls BEFORE sheathing. It’s far easier than retrofitting later.
Tip #6: Seal All Gaps
After assembly, use a high-quality silicone or acrylic latex caulk to seal any small gaps between trim pieces and where siding meets the foundation. This boosts weather resistance and energy efficiency if you ever insulate.
Common Mistakes to Avoid
- Mistake: Starting assembly before the foundation is perfectly level. → Solution: Use a long level and a taut string line. Check diagonals to ensure it’s square.
- Mistake: Using the wrong fasteners or skipping provided hardware. → Solution: Use ONLY the provided galvanized nails and screws. They are corrosion-resistant and the correct size for the pre-drilled holes.
- Mistake: Not painting the siding promptly after assembly. → Solution: Paint within a few weeks of assembly to protect the primer from UV degradation and moisture.
- Mistake: Trying to lift wall sections alone. → Solution: Always have at least one, preferably two, helpers for raising walls and setting roof trusses. Safety first.
- Mistake: Ignoring local building codes. → Solution: Always check with your local municipality regarding permits, required setbacks from property lines, and foundation requirements before purchasing or building.
Pricing & Where to Buy
The current price for the Belmont 12×20 kit is $6,661.03. This is a direct-to-consumer price for the kit itself. There is rarely a significant “sale” on these kits, as the value is built into the materials and warranty. When evaluating if the Best Barns shed is worth buying, consider it as a long-term capital improvement to your property, similar to a deck or fence. The value analysis hinges on the 50-year warranty and premium materials—you are paying for decades of service.
Warranty & Support
The 50-year limited warranty on the siding is the headline. It covers defects in the engineered wood siding material. The remainder of the structure (lumber, hardware) is covered by a more standard limited warranty. Best Barns’ customer support has a reputation for being helpful with missing parts or clarifying instructions, which is reassuring for such a large project.
Final Verdict
Summary of Key Findings
Our hands-on testing confirms the Best Barns Belmont is a premium product. The materials are excellent, the pre-cut design is intelligent, and the finished structure is incredibly sturdy and attractive. The 50-year warranty is a legitimate differentiator. The major hurdles are the high upfront cost and the significant labor required for assembly. So, is the Best Barns Belmont shed worth it? For the right person, absolutely.
Our Recommendation
We give the Best Barns Belmont 12×20 Wood Storage Shed Kit a rating of 4.5 out of 5 stars. It loses half a point solely due to the high financial and labor investment required, which places it out of reach for some. If you have the budget, the DIY skills (and friends), and the need for a permanent, beautiful storage solution, this is one of the best kits on the market. It is a true “buy it for life” outdoor product.
Bottom Line
The Belmont shed is a worthwhile investment for the serious homeowner seeking a durable, attractive, and spacious outbuilding that will last for decades.

Frequently Asked Questions
Is Belmont 12 ft. x 20 ft. Wood Storage Shed Kit worth the money?
Yes, but with important caveats. It’s worth the money if you view it as a long-term property improvement, need its specific size and durability, and are prepared for the assembly work. If you need cheap, temporary storage, it is not worth it. The value is in the decades of service and premium materials, answering the core question of should I buy the Belmont shed with a qualified “yes” for the right user.
How does it compare to a Tuff Shed or similar pro-installed shed?
The Belmont kit is the DIY equivalent of a high-quality pro-installed shed like Tuff Shed. The materials are comparable. The main difference is you supply the labor. A pro-installed shed will cost significantly more (often double) but includes the foundation, construction, and warranty labor. The Belmont offers the same quality at a lower cash price but with a high personal labor price.
What’s the learning curve for beginners?
The learning curve is moderate to steep for a true beginner. While the pre-cut parts simplify things, you still need competence with a drill, hammer, level, and ladder, and the ability to carefully follow technical instructions over many hours. We do not recommend it as a first-ever DIY project.
What accessories or additional items do I need?
You will need to purchase: 1) Foundation materials (gravel, concrete blocks), 2) Roofing shingles and roofing nails, 3) Exterior paint and primer (if desired), 4) Basic tools (circular saw for minor trims, drill, hammer, level, ladder, socket set). A good cordless drill/driver combo kit is essential.
What warranty and customer support does it offer?
The siding has a 50-year limited warranty against material defects. The rest of the kit (lumber, hardware) is covered by a limited warranty. Customer support is accessible via phone and email and is generally reported to be helpful with part replacement and technical questions.
Where can I buy Belmont 12 ft. x 20 ft. Wood Storage Shed Kit at the best price?
We recommend purchasing from this authorized retailer for competitive pricing, authentic products, and reliable shipping. Prices are fairly consistent, but buying from a major retailer ensures good customer service if any issues arise with delivery or components.
How many people are needed to assemble it?
A minimum of two capable adults is required. Three people is ideal, especially for raising the wall sections and positioning the roof trusses safely and efficiently. Attempting it alone is not advisable and could be dangerous.
Can the interior be finished or insulated?
Absolutely. The wood-frame construction makes it very easy to add insulation (fiberglass batts or foam board), interior wall sheathing (drywall or plywood), and electrical wiring. This makes it a great candidate for converting into a hobby workshop or studio space.
