Costco Is Selling a “Haven” Barn Shed That They’ll Build for You

Note: Product availability, pricing, installation areas, permit rules, and included features can vary by ZIP code and over time. Before purchasing, confirm the current Costco listing, Gorilla Shed details, HOA rules, and local building requirements.

Costco has a way of turning a casual “I only came in for paper towels” trip into a full-scale home improvement plan. One minute you are admiring rotisserie chickens. The next, you are mentally measuring your backyard for a barn-style shed with a loft, double doors, and professional installation included. That is the magic of the Costco treasure hunt, and the latest backyard temptation is the Installed Sheds by Gorilla Haven Shed, a barn-inspired outdoor storage building that arrives with one very attractive promise: they will build it for you.

The Costco Haven barn shed is not the flimsy little metal box that rattles every time the wind sneezes. It is a wood-framed, gambrel-style storage shed made by Gorilla, a shed brand known for heavy-duty construction, wide doors, built-in storage, and professional installation. Costco’s listing highlights several shopper-friendly details: delivery and installation are included, the shed comes in multiple sizes, the interior includes a shelf and overhead loft, and the structure features a 7-foot sidewall height. In other words, this is not just a place to toss a rake and hope for the best. It is closer to a mini backyard barn for tools, lawn equipment, seasonal décor, sports gear, workshop supplies, and all the things currently staging a rebellion in your garage.

What Is the Costco Haven Barn Shed?

The Haven Shed is a barn-style wood storage shed sold through Costco as part of its installed shed offerings from Gorilla. The “barn” description comes from its tall, classic gambrel roofline, which creates extra overhead room compared with many low-profile sheds. That roof shape is useful because it allows space for a loft, making the shed feel larger than its footprint suggests.

Costco’s current Haven listing includes several size options, including 10′ x 10′, 12′ x 12′, 12′ x 16′, 12′ x 20′, and 12′ x 24′. That means buyers can choose anything from a compact backyard storage solution to a large outbuilding with enough room for serious lawn equipment, bulky outdoor furniture, bins of holiday decorations, bicycles, gardening supplies, and maybe the camping gear you swear you will use again someday.

The big selling point is convenience. Rather than shipping a pile of lumber and a 47-page instruction booklet that tests your marriage, Costco’s listing includes delivery and installation. Professional installers build the shed on site, which is a major advantage for homeowners who want a finished structure without spending a weekend arguing with a level, a drill, and one suspiciously missing screw.

Why This Costco Shed Is Getting Attention

Backyard sheds are having a moment. Homeowners want more usable space, garages are overflowing, and many people are looking for flexible outdoor buildings that can function as storage, workshops, garden centers, hobby rooms, or “please let me have one quiet corner” retreats. The Haven barn shed taps into all of that demand.

The Costco angle makes it even more interesting. Costco shoppers are used to looking for strong value, bundled services, and products that feel more premium than expected. A large installed shed checks those boxes because installation can be one of the most stressful and expensive parts of buying a backyard building. When delivery and professional installation are bundled into the purchase, the comparison becomes easier for homeowners who do not want a mystery invoice after checkout.

The Haven is also appealing because it blends practical storage with curb appeal. A barn roof simply looks more charming than a basic utility shed. It gives the backyard a finished, intentional feel instead of saying, “This is where the leaf blower went to disappear.”

Key Features of the Costco Haven Barn Shed

Delivery and Installation Included

The headline feature is simple: Costco’s Haven shed listing includes delivery and installation. That is a major benefit because a shed this size is not a simple afternoon assembly project for most homeowners. A professionally installed shed can help reduce mistakes, improve fit and finish, and save a significant amount of labor.

That said, “installation included” does not mean “homeowner does absolutely nothing.” Buyers still need to prepare the site, confirm access, check permit requirements, and make sure the installation area is ready. More on that shortly, because nothing ruins shed day faster than discovering your chosen spot is blocked by a fence gate, a tree root, or a barbecue grill that has become part of the landscape.

Multiple Size Options

The Haven shed is available in several sizes, making it easier to match the building to your backyard and storage needs. The 10′ x 10′ model provides 100 square feet of space, which is already enough for a mower, garden tools, shelves, bins, and a few awkwardly shaped items that refuse to stack neatly. Larger options, such as 12′ x 16′, 12′ x 20′, and 12′ x 24′, open the door to more ambitious uses, including a workshop, landscaping equipment zone, pool-supply hub, or organized storage for a large household.

A good rule of thumb when buying a shed is to choose more space than you think you need. Outdoor gear has a strange ability to multiply. Today it is one mower and a hose reel. Tomorrow it is three bikes, a snow blower, patio cushions, fertilizer bags, a pressure washer, and an inflatable unicorn pool float with emotional attachment.

7-Foot Sidewalls

The Haven’s 7-foot sidewall height is a practical upgrade. Taller walls make it easier to move around, hang tools, mount shelves, store long-handled equipment, and avoid the “shed hunch” that comes with shorter buildings. The added height also supports the barn-style design, giving the shed a more open interior feel.

This matters more than many shoppers realize. A shed with enough floor space can still feel cramped if the walls are low and the roofline limits usable storage. The Haven’s taller profile helps make the interior more flexible, especially if you plan to organize vertically.

LP ProStruct Premium Flooring with SmartFinish

Costco’s listing calls out LP ProStruct Premium Flooring with SmartFinish, a heavy-duty flooring system designed for shed use. Flooring is one of the most important features in any outdoor storage building because it carries the weight of mowers, tools, bins, workbenches, and people. A weak floor can become the first part of a shed to sag, soften, or complain loudly.

The Haven’s floor system is intended for real storage demands, not just empty promises and one lonely shovel. For homeowners planning to store heavy equipment, this feature should be near the top of the checklist.

Interior Shelf and Overhead Loft

The included shelf and overhead loft are two of the most useful features in the Haven barn shed. Floor space is precious, and anything that can be lifted off the ground instantly makes the shed easier to use. A loft is ideal for seasonal items, storage bins, camping gear, patio cushions, holiday decorations, or lightweight items that do not need daily access.

The shelf is better for everyday tools, smaller boxes, garden supplies, and accessories. Together, the loft and shelf help keep the interior from turning into the classic “shed pile,” where everything exists technically inside the shed but nothing can be found without moving seven unrelated objects first.

Wide Double Doors

The Haven includes two doors, and the extra-wide door opening is one of its most practical details. Wide double doors make it easier to move bulky items in and out, including lawn mowers, wheelbarrows, garbage bins, bikes, snow blowers, and large storage tubs. This is especially important if the shed will store equipment that rolls.

A shed can have all the square footage in the world, but if the doorway is too narrow, it becomes a very expensive puzzle box. Wide access makes the Haven more user-friendly for real-life storage.

What Can You Use the Haven Shed For?

Lawn and Garden Storage

The most obvious use is lawn and garden storage. The Haven can hold a push mower, riding mower depending on the chosen size and entry needs, rakes, shovels, hoses, spreaders, fertilizer, soil bags, planters, and garden tools. Add wall hooks and labeled bins, and suddenly your yard equipment has a proper home instead of leaning dramatically against the garage wall.

Garage Overflow

If your garage has slowly become a museum of “things we might need later,” the Haven can help reclaim parking space. Seasonal bins, sports gear, coolers, folding chairs, outdoor toys, and patio accessories can all move into the shed. Your car may be shocked to learn it is allowed indoors again.

Workshop or Hobby Space

With thoughtful organization, larger Haven models can work as a small workshop or hobby space. A workbench, pegboard, battery charging station, and tool wall can turn the shed into a practical project zone. However, buyers should remember that electrical work, insulation, climate control, and interior finishing are separate considerations and may require permits or professional services.

Outdoor Lifestyle Storage

Pool supplies, patio cushions, grilling accessories, fire pit tools, sports equipment, bikes, camping gear, and holiday decorations are all good candidates for shed storage. The loft is especially handy for items that are used only a few times per year.

Important Things to Check Before Buying

Local Permits and HOA Rules

Before buying any large shed, check your local building department and homeowners association rules. Permit requirements vary by city, county, state, shed size, foundation type, and intended use. Some areas have strict setback requirements, meaning the shed must be a certain distance from property lines, fences, easements, or other structures.

If you live in an HOA community, architectural approval may also be required. The shed’s color, roof style, placement, height, and visibility from the street may all matter. A little paperwork upfront is far better than installing a beautiful shed and then receiving a letter written in the emotional tone of a disappointed principal.

Site Preparation

Installation may be included, but the site still needs to be ready. In general, the build area should be reasonably level, clear of debris, and accessible for installers. You should remove old structures, branches, rocks, toys, outdoor furniture, and anything else that could block the work zone.

Gorilla’s guidance emphasizes the need for clearance around the shed and access to electricity within a practical distance for installer tools. If the site is too uneven, additional leveling materials or work may be needed. If you plan to use a concrete slab, confirm the exact required dimensions before pouring, and allow proper curing time.

Foundation Choice

A good foundation helps protect your shed from moisture, shifting, and long-term wear. Common options include a concrete slab, gravel pad, concrete blocks, or treated runners, depending on the shed model, local code, soil conditions, and climate. Gravel can help drainage, while concrete is durable and appealing for heavy use. Concrete blocks are often used to support and level sheds, but requirements vary.

The key is not to treat the foundation as an afterthought. A shed is only as dependable as what it sits on. Even the nicest barn shed will not perform its best if it is placed in a low, soggy corner where water gathers like it has paid rent.

Painting and Caulking

One detail buyers should not miss: painting is typically the homeowner’s responsibility. Gorilla sheds are built with pre-primed siding, but they still need proper exterior paint. Using quality 100% acrylic latex paint helps protect the building and lets homeowners match the shed to the house, garage, fence, or landscape.

Caulking is also part of long-term weather protection. Critical joints may be addressed during installation depending on the purchase program, but homeowners should review the manufacturer’s instructions and complete any remaining caulking and painting within the recommended time. This is not the glamorous part of shed ownership, but it is the part that helps keep water where it belongs: outside.

Is the Costco Haven Barn Shed a Good Value?

The Haven shed can be a strong value for homeowners who want a sturdy wood shed with installation included. When comparing it with sheds from home improvement stores, online retailers, and local builders, do not compare only the base product price. Compare the full package: delivery, installation, floor system, roof materials, doors, loft, shelves, warranty, site requirements, customization options, and any extra fees.

A cheaper DIY shed kit may look attractive at first, but the final cost can rise once you add delivery, tools, foundation materials, roofing upgrades, flooring, hardware, paint, time, and possibly professional help. On the other hand, a custom-built shed from a local contractor may offer more design flexibility but could cost more and require a longer planning process.

The Costco Haven sits in a practical middle ground: more substantial than many basic kits, more convenient than a full DIY build, and potentially simpler than managing a custom shed project from scratch.

Who Should Consider Buying the Haven Shed?

The Haven shed is a good fit for homeowners who need serious outdoor storage and want the convenience of professional installation. It makes sense if your garage is overcrowded, your lawn equipment needs protection, your backyard tools are scattered, or you want a more polished outbuilding that looks like part of the property rather than an emergency storage decision.

It is especially appealing for people who value vertical storage. The barn roof, 7-foot sidewalls, shelf, and loft create more usable space than a basic box-shaped shed. If you are the kind of person who enjoys labels, hooks, bins, and the phrase “everything has a place,” this shed gives you a strong foundation for storage happiness.

Who Might Want to Skip It?

The Haven may not be the best choice for renters, homeowners with very small yards, people with strict HOA restrictions, or buyers who want a fully finished office or guest room right out of the box. It is a storage shed, not a tiny home. Any conversion into a living space, office, studio, or climate-controlled room may require additional work, electrical planning, insulation, ventilation, permits, and code compliance.

It may also be too much shed for someone who only needs to store a few hand tools and a bag of potting soil. In that case, a smaller resin or deck box may be more practical and less expensive.

Smart Buying Tips Before You Click “Add to Cart”

Measure More Than the Shed Footprint

Measure the shed footprint, but also measure access paths, gates, slopes, overhead branches, and the working clearance around the build site. Installers need room to work, and materials need a clear path to the backyard.

Plan the Interior Before Installation

Think about what will go inside before the shed arrives. Group items by category: lawn care, gardening, sports, seasonal décor, tools, and outdoor living. Decide where bulky rolling items will park and where shelves or hooks should go. Planning early prevents the shed from becoming a very attractive junk drawer.

Budget for Extras

Even when installation is included, budget for possible extras such as permits, HOA applications, site preparation, gravel or concrete, paint, caulk, ramps, hooks, shelves, lighting, locks, or pest prevention. The shed is the star of the show, but accessories are the supporting cast that make it useful.

Check Delivery Area Carefully

Installed shed availability can depend on state, ZIP code, local conditions, and installer coverage. Certain areas may have restrictions, and remote locations may require additional time. Always verify availability for your exact address before falling completely in love with a shed layout.

Real-Life Experience: What Owning a Shed Like This Actually Feels Like

The first thing homeowners usually notice after adding a shed like the Haven is not the shed itself. It is the garage. Suddenly, the garage has floor space again. The mower leaves. The fertilizer bags leave. The holiday bins leave. The garden tools stop leaning in a tangled metal bouquet next to the car door. The garage begins to look less like a storage unit with headlights and more like a functional part of the home.

That feeling is more valuable than it sounds. A good shed changes daily routines. Instead of dragging yard tools from three different corners, you can keep them in one backyard zone. Instead of storing patio cushions in the dining room during storm season, you can place them in labeled bins on the loft. Instead of playing “Where did I put the hedge trimmer?” every spring, you can hang it on the wall where future-you can find it without muttering.

The loft is one of those features that sounds nice online but becomes genuinely useful in real life. It is perfect for lightweight seasonal storage: wreaths, outdoor pillows, camping pads, Halloween decorations, folding chairs, and pool floats. The trick is to avoid loading it with items you need every week. A loft is excellent storage, but it should not become a second attic of forgotten objects. Use clear bins, add labels, and keep a small step ladder nearby if appropriate.

The wide double doors also make a big difference. Anyone who has tried to angle a mower through a narrow shed door knows the unique frustration of scraping wheels, handles, and dignity at the same time. A wide opening turns storage into a simple push-and-park experience. If you use a wheelbarrow, snow blower, pressure washer, or large trash bins, this feature becomes less of a luxury and more of a sanity saver.

One practical lesson: treat the shed like a small building, not a giant box. Keep air circulation in mind. Avoid storing wet items directly against walls. Use pallets, shelves, or hooks to keep vulnerable items off the floor when possible. Do not stack heavy objects in a way that blocks access to everything behind them. Create zones, even if they are simple: left side for lawn care, right side for tools, back wall for seasonal bins, loft for lightweight overflow.

Another real-world tip is to paint promptly and thoughtfully. Matching the shed to the home can make it look intentional, especially in suburban yards where HOA rules or neighbors’ opinions may exist in abundance. A shed painted to coordinate with trim, siding, fencing, or landscape colors looks like an upgrade. A shed left unfinished too long looks like a weekend project that escaped supervision.

Security is worth considering too. A sturdy shed can store valuable equipment, so use a good lock, avoid leaving expensive tools visible through windows if applicable, and consider motion lighting nearby. If the shed is far from the house, a solar light or battery-powered light can make evening access safer and less spooky. Nobody wants to retrieve a rake in the dark while wondering whether that sound was a raccoon or a haunted leaf pile.

Finally, the best experience comes from buying the right size. Many homeowners underestimate how quickly storage fills up. If your yard and budget allow, choosing a larger model can make the shed more comfortable to use. Space to walk inside matters. Space to turn a mower matters. Space to add one more shelf next year definitely matters. A shed should not be packed so tightly that using it requires a full-body excavation.

Final Verdict: A Backyard Storage Upgrade With Costco Convenience

The Costco Haven barn shed stands out because it combines a classic barn-style look with practical storage features and included professional installation. Its multiple size options, 7-foot sidewalls, LP ProStruct flooring, interior shelf, overhead loft, wide doors, and wood construction make it a serious option for homeowners who need more organized outdoor space.

It is not a purchase to make casually. Buyers should check permits, HOA rules, installation availability, foundation needs, site preparation, painting requirements, and total costs before ordering. But for the right homeowner, the Haven shed could be the difference between a cluttered garage and a backyard storage system that finally makes sense.

And honestly, if Costco can sell you a barn shed and arrange to have it built for you, the only remaining question is whether the shed will also come with a 48-pack of paper towels. Probably not. But this is Costco, so never say never.
