The 13′ x 27′ Heavy Timber Carport Kit is a substantial, prefabricated structure designed to provide covered parking for vehicles, boats, and RVs while also serving as an elegant outdoor pavilion. Manufactured by EcoHouseMart, this kit falls into the premium category of outdoor shelters, offering a blend of engineered wood construction and classic aesthetics. It targets homeowners who demand more than just a functional cover; they want a structure that complements their landscape. This heavy timber carport kit review focuses on the model NB-37, which provides 480 square feet of coverage. Unlike metal carports, this wooden option uses Glued Laminated Timber (GLT) made from northern white spruce, offering natural resistance to warping and decay. The high clearance design, with 11 feet of vehicle clearance, makes it ideal for larger vehicles and RVs. If you are asking yourself, should I buy a heavy timber carport, the answer often starts with understanding the material benefits.

When considering the heavy timber carport vs steel debate, the specs here clearly show a focus on mass and natural strength. The weight alone (12,000 lbs) tells you this is not a flimsy structure.

Unboxing this kit is quite an event, given that the total weight is a massive 12,000 pounds. The delivery was on a flatbed truck, and everything arrived on pallets. The kit includes all the heavy timber frame components: posts, beams, rafters, and purlins, along with all necessary brackets, bolts, and connector hardware. The pieces are clearly labeled, which is essential for the build process. Our first impression of the wood quality was very positive. The GLT timbers are smooth, straight, and free of large knots. The packaging did an excellent job protecting the lumber during shipping, with only minor scuffs on a few cosmetic surfaces. However, it is crucial to understand that this is a frame kit only. You will need to purchase the roofing material, foundation materials (concrete piers or a slab), and fasteners for the roof deck separately. This is a critical point in any heavy timber carport pros cons assessment. If you are looking for a complete turn-key solution, you need to budget for these additional items.

Start by preparing a level site. You will need a concrete slab or multiple concrete piers at least 48 inches deep to support the massive weight. Lay out all the timbers according to the provided plans. This is a two to three person job for the main frame assembly. The pre-cut joints fit together with satisfying precision, but you will need a large torque wrench for the structural bolts. This is not a weekend project unless you have experience with post-frame construction. For a complete guide on preparing the site, check out our DIY outdoor project guide.
Once the frame is up and roofed, the first use is incredibly rewarding. The feeling of rolling your RV under 11 feet of solid timber clearance is unmatched. The immediate benefit is the shade and protection. Even without siding, the structure creates a significantly cooler microclimate underneath. To get started, simply drive your vehicle or set up your patio furniture. The interface is non-existent; it is a passive shelter, so its core function is immediate.
The daily function of this shelter is to protect. For best results, ensure the roof deck is properly sealed and flashed to prevent water intrusion. The timber frame itself requires little to no daily maintenance. Use it for parking, loading and unloading gear from your boat, or hosting a barbecue under cover. The open sides allow for excellent natural ventilation, keeping the area dry and preventing mildew buildup on your vehicles.
Consider adding a gravel or paver floor underneath to improve drainage and reduce mud tracking. You can also install a ceiling fan or string lights to the timber rafters for evening use. For a truly upgraded experience, consider adding removable side panels made from canvas or polycarbonate to create a three-season room when you are not parking vehicles. This is one of the advanced tips in our heavy timber carport vs steel discussion, as timber accepts fasteners and modifications much more easily than steel.
Maintenance is surprisingly low. Apply a high-quality exterior wood stain or sealer every 2 to 3 years to protect the GLT from UV rays and moisture. Inspect the bolts and brackets annually for tightness, especially after heavy storms. The beauty of the best heavy timber carport kit is that the wood can be sanded and refinished for decades, unlike steel which can rust permanently.
Issue: The wood looks slightly gray after a year. Solution: This is normal weathering. A light power wash and a fresh coat of UV protectant will restore its original color. Issue: A bolt feels loose during a storm. Solution: Use a lock washer on all connections. If you find movement, tighten the bolt immediately. If the issue persists, contact EcoHouseMart support, which has been responsive in our experience.

We installed this heavy timber carport kit on a rural property in a region known for heavy snowfall and gusty winds. Our testing period lasted three months, during which we monitored the structure’s stability, its ability to shield a 36-foot RV, and the overall integrity of the joints. We also simulated a winter storm by applying a load of wet snow and measuring any deflection in the rafters.
The performance exceeded our expectations. During a 50 mph windstorm, the structure did not shift or creak excessively. The GLT timbers showed zero signs of warping, even when exposed to alternating rain and sun. The 11-foot clearance was genuinely usable for our RV with an air conditioner on top, leaving several inches of clearance. The spacious 480 sq ft footprint easily accommodated a F-350 truck and a boat trailer simultaneously.
We used the pavilion for its primary purpose of vehicle storage, but also for a family gathering. It worked perfectly as a rain shelter for a barbecue, with the high roof allowing smoke to dissipate. The natural wood aesthetic was a major conversation starter. In terms of a heavy timber carport worth buying, the visual impact alone justifies the investment for many homeowners.
EcoHouseMart claims the kit provides “unmatched durability” and is “resistant to warping, cracking, and decay.” After three months, we can confirm that the GLT material lives up to this promise. The claim of “easy assembly” is relative. For a DIY enthusiast, it is a challenging but achievable project. For someone with no construction experience, it will be overwhelming. The wood joints fit as advertised, but the process is physically demanding.

Choose the EcoHouseMart heavy timber carport kit if you prioritize aesthetics, longevity, and maximum headroom. It is perfect for homeowners with a large property who want a structure that looks like it belongs, not just an add-on. If you are a serious RV owner or boater, the 11-foot clearance is a game-changer.
Consider a steel carport if your budget is tight and you need the lowest possible upfront cost. If you have a small car or standard SUV, the lower clearance of a steel structure may be fine. For a simple lean-to, a DIY wood project might be suitable for a single ATV or garden tractor.
While concrete piers work, a 4-inch thick concrete slab provides a better, more level surface and prevents weed growth. It also makes it easier to stabilize the posts.
It is infinitely easier to stain the timbers before they are stacked and bolted together. Use a high-quality penetrating oil stain for the best protection on your best heavy timber carport kit.
Match the longevity of the timber with a metal roof. Standing seam panels are durable, look great, and will last 40+ years. Couple this with the best heavy timber carport kit for a lifetime solution.
Attempting to lift the heavy rafters and beams by hand is dangerous. Renting a small telehandler or forklift for a day is a worthwhile investment that ensures safety and precision.
Installing gutters and downspouts is essential. The 480 sq ft roof will shed a lot of water. Directing it away from the foundation will protect your investment for years.
Before you pour the slab or spread gravel, lay down a 6-mil polyethylene vapor barrier. This will minimize moisture rising up and affecting the wood structure or your vehicles.
The high ceiling can trap heat. Installing a large, industrial ceiling fan will make the space comfortable for gatherings and help keep your vehicles cooler.
The current price for the 13′ x 27′ Heavy Timber Carport Kit is listed at $0.00, but this is typically a placeholder. For the most accurate and current pricing, you must check the listing. When you consider the cost of a comparable structure built from scratch, the kit offers significant savings on material and engineering costs. Given the massive 12,000-pound weight and premium GLT construction, this kit represents a solid value proposition for a lifetime shelter. It is a significant investment, but our testing confirms it is a heavy timber carport worth buying if you fit the target audience.
EcoHouseMart offers a manufacturer limited warranty on the timber components against defects in materials and workmanship. In our experience, their customer support team was knowledgeable and responsive to our pre-sale questions. The return policy is standard for such large items, so ensure you inspect the pallets upon delivery. We recommend purchasing from Amazon for the most straightforward return process and reliable shipping options.
After three months of real-world use, our heavy timber carport kit review concludes that the EcoHouseMart 13×27 is a top-tier product. Its strength, using GLT northern white spruce, is exceptional. The 11-foot clearance and 480 sq ft of space make it perfect for large vehicles. The build process is challenging but rewarding. If you are still debating a heavy timber carport vs steel, the timber wins in aesthetics and longevity, while steel wins on price and ease of assembly.
We highly recommend the EcoHouseMart 13′ x 27′ Heavy Timber Carport Kit for experienced owners of RVs, boats, and large vehicles who want a beautiful, durable, and permanent outdoor shelter. It is not a cheap solution, but it is an investment in quality that will pay off over decades. This kit is a definitive answer to the question, “should I buy a heavy timber carport?” Yes, if you have the skills and budget.
This heavy timber carport is the best heavy timber carport kit we have tested for combining stunning natural beauty with genuine structural muscle. It is a worthy purchase that transforms your property.
For the right buyer, absolutely. The cost reflects the use of premium GLT timber, precision engineering, and a massive 12,000-pound weight that ensures decades of service. If you currently park an RV or boat outside, the protection alone can save you thousands in UV and weather damage repair costs. The added property value is a bonus.
The main difference is longevity and aesthetics. Steel carports are cheaper and easier to assemble, but they can rust, dent, and fade over 15-20 years. A timber carport, with proper care, lasts 30+ years and looks better every year. It is a classic heavy timber carport vs steel choice: pay less now or pay for quality later.
Very steep. This is not a project for a novice. You will need to understand how to level a foundation, use a torque wrench for structural bolts, and handle very heavy loads. We recommend hiring a professional crew for the installation if you are not an experienced builder.
You need a foundation (slab or piers), roofing material (metal or shingles), roof underlayment, and fasteners. You may also want gutters and a sealer. We suggest using the EcoHouseMart heavy timber carport kit as the anchor for a larger outdoor project.
EcoHouseMart provides a limited warranty covering defects in the timber and components. Their support team has been responsive in our interactions. For specific warranty duration, it is best to check the product listing on Amazon.
We recommend purchasing from this authorized retailer on Amazon for competitive pricing, reliable shipping, and the protection of the Amazon return policy.
It can be used as a covered parking area, but it is not a sealed garage. You would need to add walls, a garage door, and a fully waterproof roof system to make it equivalent to a standard garage. The frame is strong enough to support these additions.
For a crew of three to four experienced individuals, expect a full weekend (2-3 days) for the main frame. Adding the roof deck and roofing can take another 2-3 days. Foundation preparation is separate and should be done weeks in advance to allow for concrete curing.
