Zalie Greenhouse build

I have been impressed with the build quality and how well everything went together. The Zalie Greenhouse has been a welcome addition to our backyard! I tried to use the BILT App but found it not helpful. The directions say to lay everything out and check to make sure everything is included and put like items together. I only had half of a two car garage to work in so this was not possible. Everything is arranged by it how it fits within the whole pallet - not necessarily like items together. I found it very helpful to pull the packing list from each of the 8 boxes and use them to find each item as I needed it (keeping most items in each individual box until they were needed). I put each wall together in the garage, by myself, over about a two week period and then my son helped me carry them out and assemble them on a leveled area with a base made out of treated 2X4’s that had been leveled. Another son came to help us and we had everything put together in about 3 half days. We are very pleased with the results and the greenhouse is definitely a great addition to our backyard!

Beautiful and Functional for My Family!

[This review was collected as part of a promotion.] I wanted a greenhouse to extend my garden’s growing season and to extend my house plant collection more easily! I needed something that would look good in my backyard and hold up well to Midwest weather. Finally, I needed it to be functional and spacious. The Zalie checked all those boxes! We put it together over a weekend and have really been enjoying it. I can’t wait to continue to learn and use it to its utmost potential! Thank you BYD for a fantastic product!

Incredible experience from purchase to assembly.

Laid out all pieces and labeled with painter’s tape so we could easily find our next piece. So easy to assemble with the detailed directions and pre-drilled holes.

Love our Zalie

Wonderful greenhouse! The instructions were very clear every step of the way. All the pieces were clearly marked and made it a very easy build. Just plan to put in some time. It is not a one day project. But once it is done, you will love it! It is also very, very strong and stable. Now we just have to see how it holds up during a Colorado Winter.

Hard work was worth it!

The final product is awesome, can't be happier! However, prep work is a must, need to categorize all the parts and hardware! It takes time and effort, but, it was worth it! It'll take two people, one with construction knowledge!

Absolutely Worth It!!!!!!

I shopped around for almost a year for a greenhouse. I almost went with an option that would have granted me a preassembled or assembled on-site. But it would not have had all of the same features.That is offered by a backyard discovery. Zalie is a beautiful greenhouse. There are a couple of things I would change. I wish it had an additional window opening in the ceiling of the greenhouse. I'm also not a huge fan of the windows. There is a slight gap there, that if it had windows that opened that particular gap would not be there.

I should have bought this year's ago!

I'm very pleased with my recent purchase of the Willow greenhouse! Adding a greenhouse to my garden had been on my to-do list for quite a while and I am really happy with my decision to purchase this brand. I assembled this mostly solo, only needing to call upon my partner for a couple of steps where his height or extra set of hands were crucial. I found the instructions easy to follow, and the pieces well labeled, with almost all holes pre-drilled and ready to go. The completed greenhouse is not only beautiful to look at, but the wood pieces, panels, and parts all seem to be high quality. Are there a lot of parts? Yes. Will it take a good amount of time to complete? Yes. Is it worth it? Absolutely! My foundation took me at least as long as building the greenhouse did, because I choose to go with pavers. Gravel would have been immensely easier, but I wouldn't recommend it based on friends who have done this with their greenhouses. A poured concrete slab would have probably been the best option, and what I would do if I did it all again. I would recommend maybe 4 days to build it if you are working mostly solo and not rushing, like I was. Half a day to unpack and organize before you actually get to the fun part of building. It is all very well packed, but it is not packed in the order that you need the parts, so pre-organizing it is essential to making the rest of the project go smoothly. You will need space to do this. This is very clear in the instructions as well. I kept a table set up near my build space, for all the parts/tools. For the greenhouse itself, I built it all the way up to before installation of the poly panels, then I applied the required sealant via spray application, to the frame inside and out. I also laid out all the other all the other remaining pieces at that point and sprayed those, so they were ready to go after the panels went in. That part only took a couple of hours. I hardest part was the roof, which took almost a full day in itself, due to all the up and down on the ladder. I am only 5'2", and even on a ladder, reaching as far as possible, I wasn't able to reach the center area of the roof in other to screw on the metal seam covers or apply sealant. Even my 6'2" partner found this a bit awkward/difficult. But we got it done. Once I got the door and window on, the plants moved in and I took my time with the other accessories because I don't currently have the power/water lines available yet. Oddities I ran in to: There were two holes not pre-drilled on the top frame pieces, that should have been. Easy fix, but it threw me off for a bit because I had to go back and re-check all the prior steps to make sure I hadn't made an error. At the very end we noticed there was also an extra pre-drilled hole in the top frame above the door, that wasn't utilized in the instructions- again- had to re-read everything to make sure I didn't miss a step. I wish they would have sent a real tube of silicone that goes in a caulking gun instead of the ones they did. Most people who own the other required tools- drill/square/rubber mallet/crescent wrench's, own a caulking gun. Finally, there are a LOT of extra parts left over when you are done, it's okay, don't sweat it. And hey, I had an extra part for the mysterious extra hole above the door, that matched everything else perfectly, so all is well that ends well. All these things are very minor in the big picture; I mention them only because I think they can be helpful to anyone still getting ready to do their own build. So long story, short, I can honestly say this kit is high quality and has many of the little extras you might be left wanting, if you go another route. To me it was worth the money and time spent and look forward to enjoying it for the many years I know it will last!

Perfect lil green house thats affordable too.

I purchased this green house in march, came in a little under 2 weeks and dropped in my driveway. I built the whole thing pretty much solo, taking about 3-4 days. I dug a somple PT treated dimensional lumber foundation by digging trenches, laying some gravel and setting the lumber in the trenches to the foot print of the green house. There are lots of parts, and i highly recommend organizjng everything first by number and setting it up as close to where your going to build it (stupidly i walked back and forth between my driveway and the site every time I needed a piece) Anyway, the green house came together great! I believe at the sale discount, this is going to be cheaper than buying your own lumber and design/building it yourself.

Great Greenhouse!

Absolutely love my greenhouse! My husband and I built it over prob a couple weeks, which is fine, we were in no hurry. But it was pretty straightforward and came with all the pieces and parts. Nothing came broken. I haven't used it much yet, since it's been too hot. But I plan on using it next spring for sure! Love the look and size of it. It's perfect!

Great Design!

I absolutely love my new greenhouse. The automatic ventilation and the hose spigot are excellent features that really help manage the plants I keep in there. The design is aesthetically pleasing and the polycarbonate appears to be really durable. Looking forward to all the things I can grow in my greenhouse.
