What our customers say

One of the best purchase I’ve made in forever.
“I bought my shed in 2020, and it’s been perfect. I ran highspeed internet to my shed and it’s got full electrical. All wifi plugs so I can control everything using Alexa or mobile app. I have a dedicated electrical circuit for my minisplit, so have full control over temp. Minisplit works great in here, with one of the smart thermostats, I can control temp from my phone and schedule, so in winter, it turns on about 30 minutes before I need to come in so its not an icebox and summer, it cools down in a few minutes so its never an issue. I have family that comes and stay during the summer and winter and they sleep in here (queen pullout sofa). They love it. One of the best purchase I’ve made in forever. I get so many compliments on it too as opposed to tuffsheds which are not visually appealing."

Outstanding product from top to bottom
“The wood is top-notch and really well crafted—the doors and windows feel super solid and sturdy. Putting it together was a breeze thanks to the clear instructions and all the parts being there—no surprises or fixes needed. It arrived quickly, and the team was great about answering all my questions honestly and promptly. In the end, it looks amazing—like a custom build that would’ve cost three times more. It’s nothing like those generic kits from big-box stores. Easily a five-star experience—would definitely recommend!"

We Love Our Shed!
“We purchased a Whales 10x10 in 2014 and love it. It went together like a dream, and we have appreciated the storage it has lent us over these past years. Once the shed was completed, roofed, and painted, with window boxes added, my 97 year old mother said she wanted to live in it!”

An important place of our home
“I want to let you know how much we love our shed. Now 3 + years after ordering it has become a very important place for us, an extension of the house. An office, art studio, dining room, and cozy place to take in the weather, it is a place to talk. Everyone that sees the shed wants one. I have shown it to multipal interested people whom I do not even know. I also want to congratulate you for inventing and producing such a brilliant and importaint product. It has made our living space much better."
