Awesome product!

Bought this about 6 weeks ago. My husband and I were able to assemble it no problems! And we are both retired! Love the look of it and am looking forward to using it!

Great Greenhouse

We purchased this greenhouse about a month ago and just love it. We wanted a greenhouse for a very long time and chose yours in our long time search. Very easy to put together and looks beautiful. Just the right size for our needs!

So well thought out

We are so excited about our new greenhouse. It was a dream to put up and it is so well thought out. Exactly what I was looking for with ventilation and fans as well all my plants are ready to grow this summer and it fit perfectly on my back patio

Worth the Price

Impressed with the high quality of this greenhouse! Solidly made. Looks amazing. Was like a lego kit. Follow the instructions and it goes together nicely.

As advertised

Only tried this kit because the reviews were so good. Unboxing and organizing was tedious. Could not believe how easy assembly was. The pre-drilled holes and labeling system was great.

Happy with Greenhouse

Was very impressed with the Greenhouse. It was shipped quickly. All parts were acounted for and labeled. Took 2 people all of 2 days to erect. Instructions were very good and everything fit together perfectly. Would definitely reccomend it.

Hope It Is Worth the Effort

I purchased this product in June 2025 and finished (mostly) in September. That should give you a clue how easy and quickly it can be built. Pictures in the Installation Booklet were very helpful but must be read VERY CAREFULLY. It would help if pictures were even more detailed. Be prepared for a ton of parts being dumped on your driveway. It took weeks to separate and organize the parts. Hope you have a lot of space available. The roof of the building CANNOT be constructed as described, even with lots of extra helpers. We successfully put it together in an entirely different order. Details are available for a small fee. The use of metal pieces looks like an afterthought - it seems like overkill. The metal pieces beg for predrilled holes. We threw away the ones separating the roof panels since the polycarbonate joint connectors, properly sealed with the provided silicone, seem more than adequate. We used the rest of the metal parts because they made the structure look nice. Another source of confusion and frustration: We knew that spare parts would be included by having them lie around but did not know if they were indeed extras or would be needed later during construction. Towards the end of construction, we ended up with a door handle that did not include the pictured plate that would use bilts to hold the front and back pieces together. We manufacted a solution that mostly works. I will have to use super glue to hold it together if I don't get a complete working replacement There's more, but you get the idea.

Great overall quality

Just put one up for a friend, overall good quality. Took me 4 days of 4 to 5 hour days, so not too long. Biggest gripe is the silicone, 2 bottle exploded all over when squeezing them. Ended up saving the hassle and bought a tube of clear roof adhesive, much easier to apply. Also couldn't find anywhere in the instructions for the double sided tape.

No more weeping for my Willow!

Absolutely love my new greenhouse! It is exactly what I have always wanted. First of all, love the design. We live in the mountains in the Shenandoah Valley of VA, so we built the decking platform in advance. We enlisted some friends for our building weekend. Taking the time to open every box & lay everything out and organize is key. As so, many of said, everything is clearly labeled and align with great detail. Keeping it square is crucial in the end! We spend a good 2 1/2 days to complete it of course, then I started customizing! We put insulation down on the floor and then laid finished pine on top, which I stained darker for contrast. We also are adding a small sink that we will find very useful. It’s as tight as a drum and we’re so excited for spring. Great product and great value. Highly recommend!

Best instructions ever using 3D application.

all parts were marked and referred to during each step of the build. all steps were very clear and not confusing. what makes this build the best I've seen is being able to look in detail using the computer app to ensure that pilot holes and grooves in the material or in a proper position. without instructions this project would be very difficult. I feel that a beginner DIY'er would get a sense of pride building this high quality greenhouse. Nothing was spared in the materials.
