Pre-Engineered · Delivered · Installed in 1-3 Days
From $1,995 · Rent-to-own, no credit check · Free delivery & installation
Pre-built storage sheds are the fastest way to add weatherproof storage to your property. Unlike kit sheds (which take weeks of weekend assembly) or stick-built sheds (which can take months of construction), our pre-built sheds arrive fully engineered and are installed on your prepared pad in 1-3 days by our professional crew. No construction project. No DIY frustration. No contractor to hire separately.
Bulldog Steel Structures manufactures pre-built storage sheds from compact 12×11 units ($1,995) up through 24×40 large storage buildings ($14,995). Every shed is pre-engineered steel construction, includes stamped engineering drawings for permit submission, carries a 10-20 year warranty, and qualifies for our rent-to-own program with no credit check and no interest.
No credit check
A good pre-built storage shed should pay for itself — not through monthly rent to a self-storage company, but through equity in a structure you own. Our rent-to-own program makes that math work for buyers who don't want to pay cash upfront or deal with traditional loan paperwork.
Approval based on income verification, not credit score. 15-minute application, same-day approval typical.
Straightforward monthly payments with a reasonable markup over cash price — no compounding interest, no origination fees.
36-month, 48-month, or 60-month plans. Monthly payments typically run $55-$280 depending on shed size and term length.
Pay off any time with no prepayment penalty. Many customers pay off within 18-24 months.
A 10×20 commercial storage unit runs $150-$300/month nationwide. Your pre-built shed on rent-to-own typically costs $130-$180/month on comparable size — and you own it after the term.
All prices include free delivery and professional installation on prepared level ground within our 30+ state service area. Rent-to-own available on every size with no credit check. 14-color paint selection included.

Buyers researching storage sheds generally compare three options: kit sheds (DIY assembly), stick-built sheds (contractor construction), and pre-built sheds (our category). Here's the direct comparison on the factors that actually matter.
| Factor | Pre-Built (Us) | Kit Shed (DIY) | Stick-Built |
|---|---|---|---|
| Price (12×21 shed) | $2,395 | $1,500-$2,800 + your time | $4,500-$8,000 |
| Your time investment | ~1 hour (order + prepare pad) | 30-80 hours of DIY work | 8-16 weeks managing project |
| Installation time | 1-3 days by our crew | 2-4 weekends solo, 1-2 with help | 4-10 weeks contractor time |
| Engineering stamps | Included | Rarely included | Varies by contractor |
| Warranty | 10-20 year manufacturer | Limited (your assembly voids most) | 1-year workmanship typical |
| Lifespan | 50-60+ years (steel) | 15-30 years (varies) | 25-40 years (wood) |
| Fire resistance | Excellent (steel) | Poor (wood kits typical) | Poor (wood construction) |
| Annual maintenance | $30-$80 | $150-$400 | $200-$600 |

From a mower and garden tools to a small business's inventory, these are the six ways customers use their sheds — and the sizes that fit each one.
The #1 use case. Lawn mowers, string trimmers, leaf blowers, pressure washers, gas cans, hoses, hand tools, garden supplies, seasonal decorations — all the stuff that doesn't belong in the garage but needs to stay dry and secure. A 12×21 pre-built shed holds a riding mower plus everything else a residential property needs.
A pre-built shed makes an ideal starter workshop. A 16×21 or 20×21 shed gives you room for a workbench, tool storage, and project space. Add electrical pre-wiring, insulation, and a workbench light package, and you have a dedicated workshop separate from your garage or house.
Hobby cars, motorcycles, musical instruments (climate-controlled), collection storage, model trains, hunting gear, fishing equipment — pre-built sheds give hobbyists dedicated space without carving it out of the family garage.
Small businesses need secure storage for inventory, tools, equipment, and seasonal items. A 20×26 pre-built shed provides commercial-grade storage at a fraction of warehouse rent cost. Landscape companies, construction trades, mobile service businesses, and e-commerce sellers all use pre-built sheds this way.
Pool pumps and chemicals need weatherproof storage separate from the house. Pool supplies, pool toys, outdoor furniture during winter — a 12×21 or 14×26 pre-built shed handles the full pool-area storage load.
Specialized recreational vehicle storage requires more width than a typical backyard shed. A 14×21 or 16×26 pre-built shed provides a dedicated garage for ATVs, UTVs, dirt bikes, or motorcycles with room for gear, trailers, and maintenance supplies.
Six steps from a list of your stuff to the right size. When you get to step 5, match your number against the price table above.
Walk through your garage, basement, and current storage spots. Everything that currently has nowhere good to live is a candidate for the shed. Group items by size (small tools vs mowers vs seasonal furniture).
Riding mower? Need 60+ inches of width clearance. Snowblower? Need 36+ inches of width + length for handle. ATV? Need 50+ inches of width + 90+ inches length. Your biggest item sets the minimum interior dimension.
You need clear aisles to move around items. Add 24-36 inches of aisle width on at least one side of your largest item. For sheds that will hold multiple items, add aisle space between them too.
Buyers almost always underestimate how much they'll want to store. Add 25-40% buffer to your minimum calculated size. The marginal cost of a larger shed is low ($400-$800 difference between sizes); the cost of outgrowing it is substantial (you'd buy a second shed).
Common right-fit sizes: 12×11 for pure overflow storage, 12×21 for a residential property with a riding mower, 16×26 for a workshop + storage combo, 20×26 for a serious hobby or small business operation, 24×40 for maximum residential-scale pre-built shed.

Bulldog Steel Structures delivers pre-built storage sheds throughout a 30+ state service area covering the East Coast, Southeast, Mid-Atlantic, Midwest, South, and parts of the Southwest. Call us with your ZIP code to confirm your exact delivery availability and timeline.
Free delivery and professional installation are included for all addresses within our service area. There are no hidden shipping charges, no 'last-mile' delivery fees, and no separate installation contractor to hire.
Check My ZIPPre-built means the shed is pre-engineered at the factory (every component designed, cut, and prepared to exact specifications) and professionally installed on your site by our crew in 1-3 days. It's the middle ground between fully-assembled sheds (which have size limits around 10×20 because they have to be towed to your site) and kit sheds (which require 30-80 hours of DIY assembly). You get the convenience of professional installation with the size flexibility and durability of custom metal buildings.
Total timeline from order to standing shed is typically 3-6 weeks: 3-4 weeks factory manufacturing + 1-2 weeks shipping to your site + 1-3 days installation. Rush builds (urgent timeline) can compress this to 2-3 weeks total. Compare to kit sheds (immediate delivery but 2-4 weekends of DIY work) and stick-built sheds (4-8 months for a contractor to complete).
No. Our pre-built sheds install directly on a prepared level pad of compacted gravel or dirt. The shed anchors to the ground with mobile home anchors (for concrete pads where present) or auger anchors (for dirt/gravel pads), both included at no extra charge. You CAN opt for a concrete floor if you want workshop-grade flooring, but it's not required for the shed itself.
Start with your biggest item: a riding mower needs 60+ inches of width, an ATV needs 50+ inches, a snowblower needs 36+ inches plus length. Add 24-36 inches of aisle space, then add 25-40% buffer for growth. Common right-fit sizes: 12x11 for overflow storage ($1,995), 12x21 for residential with a riding mower ($2,395), 16x26 for workshop + storage ($4,195), 20x26 for serious hobby or small business ($5,995), 24x30 for dual-vehicle + workshop ($11,495).
Yes. Our rent-to-own program is available on every size with no credit check, no interest, and 36-60 month terms. Monthly payments on a $2,395 pre-built shed run roughly $75-$80 on 36 months, and on a $5,995 shed roughly $130 on 60 months. Early buyout available with no prepayment penalty. We also work with traditional lenders for buyers preferring bank financing.
For most buyers, yes. Pre-built sheds cost 20-40% more than kit sheds up front but save 30-80 hours of DIY assembly time, include professional engineering stamps for permits, carry 10-20 year manufacturer warranties (kit shed warranties often void when you assemble them yourself), and typically last 50-60+ years vs 15-30 for kit sheds. If you value your weekends and want a shed that will outlive you, pre-built is the better long-term value even at the higher upfront price.
The terms are often used interchangeably but describe slightly different things. 'Prefab' (prefabricated) is a broad umbrella covering any shed built off-site and delivered — includes kit sheds (DIY assembly), fully-assembled sheds (small sizes towed to your site), and pre-built sheds (our category — pre-engineered + professional installation). 'Pre-built' specifically means pre-engineered with professional installation included. All pre-built sheds are prefab, but not all prefab sheds are pre-built.
Bulldog Steel Structures delivers pre-built storage sheds throughout a 30+ state service area covering the East Coast, Southeast, Mid-Atlantic, Midwest, South, and parts of the Southwest. Call us with your ZIP code to confirm your exact delivery availability. Free delivery is included in your quoted price — no hidden shipping charges or last-mile fees.
Our largest standard pre-built shed is 24×40 (960 sq ft) at $14,995. For larger storage needs, we offer extra-large metal sheds up to 50×80 (4,000 sq ft) through our Extra Large Metal Sheds product line — these are still professionally installed but use heavier framing suitable for commercial-scale storage.
With basic maintenance (seasonal walkaround, occasional hinge lubrication, touch-up paint for scratches), our pre-built steel storage sheds last 50-60+ years. The structural steel can last 75-100 years — paint and panels are typically the limiting factor. 29-gauge painted panels last 25-40 years before needing repainting. 26-gauge upgraded panels last 40-60 years. Compare to wood kit sheds (15-30 year typical lifespan) and stick-built wood sheds (25-40 years).
Yes, when properly configured for your climate. Standard regular-roof pre-built sheds handle 20 psf snow load and 90-115 mph wind (adequate for mild-climate zones). For snow country or hurricane coasts, upgrade to vertical roof (40-50 psf snow, 140-170 mph wind). All our pre-built sheds include stamped engineering drawings showing specific ratings for permit submission.
That's it. 3-6 weeks after you place the order, our crew is at your prepared pad building your shed.
Use the pricing table above. If you're unsure, 12×21 ($2,395) is our most popular small shed and 20×26 ($5,995) is our most popular mid-size.
Call or submit the online form with your ZIP code and selected size. We confirm delivered pricing within 24 hours.
Cash buyers place a deposit and we schedule manufacturing. Rent-to-own buyers complete a 15-minute application (no credit check) and typically get same-day approval.
If your storage need is bigger than our pre-built lineup covers, see our extra large metal sheds (up to 50×80 commercial scale). For enclosed vehicle storage specifically, see our metal garages. For dedicated workshop configurations, see our metal workshops line.
I'm really happy with the way my building turned out! Due to living in city limits I had to make changes to my original plan but working with Bryan made it easy. He was great to work with!
Bulldog Steel Structures is fantastic. We had a 24'x40' garage built with two 10' garage doors, an entry door, two windows and fully insulated for under $16,000. The whole experience was so easy. Our salesman was Bryan Valadez. Bryan was so helpful and was easily available to answer my questions. Rebekah Aldridge handled all the documents and signing of them. The whole process was great. The building is well constructed and the crew that erected it were courteous and cleaned the worksite afterwords thoroughly. They did an excellent job in a time efficient period. Our experience with Bulldog Steel Structures was just great and we highly recommend them.
I'm in early stages, just put deposit on building. I reviewed about 10 quotes and worked with many vendors in the space to assess. Constance from Bulldog Steel Structures made the experience fabulous and was key in our decision making. It's so refreshing to see a company like this have such outstanding client facing service. We are excited and huge shout out to Constance and the team. Bravo!
I have purchased two structures/buildings from them and have been greatly satisfied. From "idea to implementation" it has gone smoothly. I love the idea of having one single point of contact (Noah) for any questions or concerns. The install crew comes in and gets right to work and the quality is the best I have seen. Highly Recommend!
I worked with Bryan Valadez in putting together my bids for a 2000 SF shop/garage. He was great to work with, very quick to respond and answered all my questions and concerns during several very thorough conversations regarding my project. I recommend you give Bulldog a shot when searching for your next building, their pricing was very good compared with some of the others, and they just seemed to have it very together for their process. Great Job, thanks Bryan. Jason
Showed up on time and excellent quality. Could not be more pleased with the results!
I called and spoke to Bryan. With some back and forth he helped me finalize the design (40x100 foot print). I placed my order and had to wait for my King County building permit to be issued. Once the slab was completed the installation team arrived with all the pieces. They got right to work and the building was completed in 8 days !!! I would highly recommend Bryan and Bulldog to any one :) Many thanks john in the pacific northwest
Great company to do business with. Would recommend them to others.
Great to deal with. Building went up with no problems.
I had a great experience with Bulldog Steel Buildings. The representatives were able to help me move from the online design to an actual building design to meet my goals. They set up the delivery and installation which turned out great. Installation was scheduled quickly after the foundation was done; and the building was completed within 2 days. Pricing was reasonable, and I'm very pleased with my new building.
Bryan was great- honest, helpful, responsive and knowledgeable. I will call him if I ever need another steel building
This company is the real deal. They go over and beyond to satisfy their customers. It is a joy to work with them. They are very knowledgeable and efficient. I looked forward to finishing my project with them.
Humberto was very responsive and it was a pleasure to work with. He went above and beyond to get delivery scheduled as soon as possible for our 30x50 building. Great company to work with.
Hey folks - these people at Bulldog are real. Noah helped me all the way through - extremely patient and knowledgeable. He answers most often and when he doesn't it's easy to get another HUMAN to speak with. I looked at several companies for this project - I settled on the right one. If you wind up doing business with Brian - you're in luck there to. Outstanding work - worthy of trust.
I purchased a 26x32 Garage from Bulldog Steel Structures they had it finished in two days. It looks really nice and the install crew was great. I’m thinking of getting another building and I will definitely contact Bryan Valadez again at Bulldog.
Great experience from start to finish. The sales process was easy and Casey helped me revise my plans several times to get the right building for my needs. Communication was excellent! The build crew was on time, friendly and professional. Beto took the time to understand what cutouts I needed and why I needed them in the sizes planned. Exceptional work. Highly recommend. Thank you!
I would recommend Bulldog Steel Structures highly. They are very professional and accommodating. Want to give special thanks to Randall Hall and also matt preslar. They were very accommodating and helping me fill out paperwork and handling things when a timely basis. The building we were very satisfied with and the installers also were very polite and had things done on a timely basis. Thanks again Randall and Matt you`ve got my five star rating
Bulldog has been great to work with. They explained everything from beginning to end. I live in the mountains of New Mexico and the staff made sure that my garage had the right support needed for this area of the country. I would highly recommend them for anyone building a new carport or gaeage!
Good design tool on their website. Great customer service.
Have had nothing but a positive experience with Bulldog! Bryan was super helpful and still is after our install! He still responds super prompt and helpful. No complaints about our structure, as it looks amazing! Installers did a great job and picked up very nicely after they were done. Highly recommend!!
I have now had my building in place for 3 months and I want to say that the whole team at Bulldog was very helpful throughout the entire process. My salesperson, Matthew, was extremely responsive. He was very helpful with the design phase, where we went back and forth with 3-4 different designs before settling on the perfect one. He always got back to me right away when I had a question. Although the delivery was delayed, understandable with the pandemic, he helped interface with Carolina Carports when I had delivery questions. So far I have no issues with the completed building. No leaks and all the doors are functioning perfectly. I would highly recommend using Bulldog for all your metal building needs.
Frank Rangel was very helpful and respectful. Also very understanding. I was pouring a concrete driveway and trying to put my down payment down. I may of got a little frustrated in the middle of it all. I could see the smile on Frank`s face the whole time! Thank you sir!
This is my second building from bulldog and I`m buying the same building , just different colors. They are great buildings that are strong and economical.
Excellent customer service during my order process, answered all my questions and they were very patient.
The website was very flexible and helped me customize my carport. The Bulldog staff was very prompt and helpful throughout the process.
Put up a RV cover for me on a concrete pad. Turned out great and the guys cleaned up after the work. Very satisfied. Would recommend these people.
I love my “She Shop.” It was amazingly easy. I sent an email, made 2 phones calls and it was done. The installation went even easier. Three guys showed up one day and finished the next. They were polite and cleaned up after themselves. My husband’s friends are all very impressed with the construction and materials used but were amazed at the reasonable price. I could not be more pleased. Thank you
I visited their website and used the 3D estimator and was able to see my building with doors, window placements, colors,and overall look. When you add or change any feature, including size, you can immediately see the result and change in price (if any). You can rotate the structure to see the overall look and framework. Once I placed my order, it was quickly and efficiently handled and the cost was lower than the estimate on the website The installers showed up early one morning and by noon the next day they had completed the structure. Everyone that comes by remarks on how nice it looks. I am very pleased with every aspect from ordering to installation.
