How We Build Your Custom Shed

Watch the video below to see the steps we take to build a standard shed!

Your perfect shed, custom built for you in Casselton, ND.

Depending on the city regulations, generally there will be a 3′ or 5′ setback from the property line for your shed. There may be a size limit for whether or not a permit is required, and watch out for those pesky HOA rules as well.

Many people want bigger sheds to maximize their space, and we build a lot of big sheds! For larger sheds, obtaining a permit is generally pretty easy. We can help you out with the process along the way.

Simply visit the building department, or apply for a permit online, and we can provide the necessary drawings or answer any questions that may arise. We are here to help!

Beau did an outstanding job building my shed on site. Despite the challenge of working in a fenced-in yard, they completed the project quickly and efficiently, all in just one day! They were extremely transparent and honest throughout the entire process, making it a stress free experience. Their pricing is very reasonable, and they’re incredibly easy to work with. If you need a shed built, don’t hesitate and hire Square Shed! Highly recommend!

They site built a shed for us 1 year ago. I purposely waited a year to review it. We are happy with our purchase. They did everything they said they would do for the price they quoted. More importantly, they did everything on time or ahead of the time they promised. This is absolutely unheard of with anything contractor related. Unheard of. The quality seems to be good one year later with no need for any return visits. (Again, this is unheard of.) They aren't the cheapest option, but they certainly make up for it in quality and keeping their word. I would hire these guys again.

Just a note to say I would have this company build again and again for me. I was notified if any changes always on time and workmanship was excellent. If you need a shed built on site the only way to go. Thank you so much. Sharon n

Beau was a pleasure to work with during the building process. I am extremely happy with the build and quality of the work. The shed was completed in a day with time to spare. The transparency and integrity experienced during our initial meeting ensured me that I made the right choice of going with SquareShed.

Square Shed built exactly what I wanted. Great communication via text and email explaining the process and the different sheds that were available. I went back and forth with the design of my build and they sent over several detailed drawings until I decided on what I wanted. My shed had to be built on a slab and they accommodated my needs and deducted a fair amount for the wood flooring. The build only took 2 days onsite and the guys were great to work with and very polite. I highly recommend Square Shed for a great shed with a great price. Rick G

Square Shed was fantastic to work with! From start to finish, everything was smooth, professional, and way above expectations. Special shoutout to Beau, the owner—his leadership and attention to detail set the tone for the whole experience. And Levi, the Fargo guy running the show, made everything happen quickly and flawlessly. Those two deserve all the credit for making the process not just easy, but actually enjoyable. If you want a company that does things right, treats you well, and delivers top-notch results—Square Shed is it. Highly recommend!

Beau and his team were extremely knowledgeable, friendly and patient with our somewhat complicated build. Their attention to detail was second to none, and this is high praise coming from a very picky and detailed oriented client! I would highly recommend and wouldn’t hesitate to use their services again for future projects!

Levi, Jordan and Landon did a fantastic job. They had to deal with the cold and rain in the beginning and with heat and humidity during most of the day. Very friendly and listened to what and where we wanted the shed. We really appreciate what they did, all in one day!!! Would recommend Square Shed to everyone!!

Highly recommend! Very responsive and excellent communication throughout. Not to mention they built our 10x12 shed in 1 day on the hottest day of the year! Hard working guy for sure. You won’t be disappointed.

Steve H.

Wow! Had a 10x12 installed today and could not be happier! Every step of the way, from quoting to install, was handled quickly and professionally. Beau stayed in constant contact during the quoting and scheduling phase, answering all of our questions and concerns. The install team took less than a full day to complete the work and left the site cleaner than they found it. Would highly recommend this company to anyone needing a shed built on their property. Will use again.

Square Shed did a fantastic job installing a shed in my yard. They arrived exactly when they said they would, were very respectful and friendly throughout the process, and finished it exactly on time and for the price agreed upon. If you need a reasonably priced shed built in your yard, Square Shed is absolutely the people to contact.

My family’s experience with SquareShed was nothing short of spectacular. The owner’s accommodating spirit combined with the top-notch service provided by all of the employees, made for a truly relaxing and enjoyable experience. Beau and his crew went above and beyond our expectations, by listening and brainstorming options which, in the end, ensured that our build was exactly what we had envisioned. We were incredibly impressed with the efficiency with which they worked, finishing the project in less time than we had imagined, but with attention to even the smallest details. I hope all of our family’s projects will go as smoothly as this one but I’m betting I’ll be hard-pressed to find a more professional company to work with.

We are very happy with our new shed. It was made to the exact specs that were discussed and quoted, no surprises!! The workmanship was top notch . All walls, floor, and roof are plumb and square. All workers were very courteous, professional , and hard working. They took less than one day to complete the build. All wrappings, trash, and left over material was picked up and taken away. We would not hesitate to recommend Square Shed.

As a realtor I am constantly asked for referrals for various vendors. I will now be recommending Square Shed! They were careful to check my build request details, great communication and reliability. They were able to return and make some small adjustments to make my shed the best on the block! Now I have the shed of my dreams! Thank you Beau and all the guys at Square Shed!

I had been looking online at pre-build sheds for several months. Once I decided it was time to buy, the sheds I had been looking at had been sold, so I started looking again. This time, I found SquareShed and liked that they build onsite, they use 2"x6" boards for floor trusts (pre-built only used 2"x4"), you don't have to tear down your fence to get a pre-built shed into your backyard, and the price was similar to (if not less than) the smaller pre-built sheds I had considered. I called them on 9/5/24 (after 5:00pm) to ask some questions and the owner actually answered the phone (impressive). He asked me to submit a request online so he could get me a quote and told me to contact the City of Fargo to start a building permit application for my 12' x 24' shed (you don't need a permit for some smaller sheds). On 9/16/24, one of their men came over to see exactly where the shed would go in my yard, confirm the size/features I wanted, and get my deposit. Later that same day, the owner emailed me the drawings I needed to submit with my permit application and gave me the answers I needed for questions on the application I wasn't sure how to answer. On 9/20/24, I got my permit from the City. On 9/24/24, the crew arrived to start building. By mid-afternoon the next day, my shed was finished, my yard had been cleaned up, and they were gone (when they said they'd get it done in 2 days I wasn't sure they'd be able to do it -- but they did!). Now I just need to move everything I want from the garage and my older, smaller sheds (that my wife is VERY happy I'm getting rid of) into the shed. Go online. Check them out. Based on my experience, I highly recommend SquareShed!!!

The shed SquareShed built for me is perfect! Beau is great at communicating throughout the process, which I really appreciated. More importantly though, he built a sturdy, high-quality shed with close attention to detail at a very reasonable cost. Plus, he did it all in one day! I hope he expands his business and adds decks or stairs to his offerings. I'd be very happy to his business again.

We are so incredibly happy with Square Sheds. They were honest and transparent from the beginning. They worked with us on our deadline, and were very kind. They finished our size of shed in a day, start to finish. They cleaned up after themselves and left us with a perfect shed. We couldnt be more happy with their service and workers

I struggle to find the words to express how great SquareShed is. From the beginning the communication has been the best. Beau has kept me in the loop thru the whole process. Something that many companies do not do. I did shop around and the biggest selling feature with SquareShed for me was the foundation. I know that shed will stand for a long time. So shop if you want, you may find cheaper but you won't find better quality. I love my new garden shed! Thanks to your team and to you Beau!

Had a great experience with Square Shed. From the initial contact, the communication with Beau was timely and professional. He followed up with all request and did exactly what he said he would. They arrived on the date as promised and built a 10x12 in about 10 hours. The quality and construction of the shed is excellent. The best part is with Beau and his team building on site, I did not have to remove my fence and they did not tear my yard up with heavy equipment. They left my property as clean as they found it. Highly recommend Beau and his team!
