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.

I bought this about a month ago. While it does take some time putting together the end result is a wonderful greenhouse. Well worth the effort. Very well thought out assembly instructions which I had to work around a little as we didn't have enough space to assemble the roof frame separately. I assembled the roof in place rather than on the ground. Using this method meant that I was able to assemble the whole greenhouse by myself albeit two people would make it go a lot faster.

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.

I am very happy with this greenhouse it is very well engineered and constructed. You can tell a lot of thought went into the design. Lots of screws of just the right size every one pre-drilled with incredible accuracy. Looks beautiful and feels really solid.

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.

Well designed, quality wood, and love the built in vent fan. This is the ideal size greenhouse for our property.

easy to build, just follow the instructions and line up your guide holes. I built all four walls first, then put everything together. for clear and visual instructions download bilt app for a 3D view.

Love, love, love my new retreat / greenhouse. Unlike other reviewers it took us 2 weeks to build but only because we worked on it 4 hours a day (heat index was brutal). Got stuck twice, video straightened us out. Would recommend highly.

me being 25 instead 74 and 90 degree weather. darker stamps on the wooden parts. resealable bags for screws, bolts, nuts and washers. bbuilt on a level and square trex deck.

I just finished building my greenhouse and I am so happy with how it turned out. The instructions were extremely easy to follow and it was a labor of love well worth it! Solid quality.
