High Quality Solid Build - Cute Too!

I purchased this greenhouse in September as a way of protecting my potted plants and succulents from our harsh North Texas winters. We have made it through several hard freezes successfully and I am very pleased! We sealed with a clear Thompsons Water Seal and it looks beautiful and smells like my grandmother's cedar closet! I love it- I am happy I spent the money for a quality product that was easy to assemble, sturdy and so cute!

Nice Kit

Very impressed with the kit. Very good instructions and all the pieces fit like they should. The packing folk are on top of their game. Nothing was missing and everything was labeled well! Did not have power on the property where we put it, so added some solar panels to power the fan.

Beautiful Greenhouse

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.

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 greenhouse!

WE bought this in fall and have been assembling bit by bit as the weather permits, here in northern Illinois. It is an amazing kit, well made with great directions to follow. Since we couldn't lay out all the pieces, one of my jobs was finding the parts, that that was simple as each box comes with a list of what it in it. It is beautiful and looks amazing on our lake shore. Can't wait til summer to grow some great plants! For the winter it is going to be a warming house for ice skating! Love it, Glad we decided to go with this kit instead of build from scratch. I honestly think with the quality, it was less to use this kit than to build ourselves!

Impressive Quality and Great Design.

I recently finished our new Zalie 12x7 greenhouse and we are thrilled with how it looks in our backyard. As a retired residential contractor I was very impressed with the quality of the kit and the ease of construction. All of the components fit well and the pre-drilling, including pilot holes, was right on. I took the time to pre-stain every piece of cedar on all sides and ends to ensure maximum protection in our wet environment.

Built To Last Designed To Impress

I recently purchased the Zalie 12 x 7 greenhouse, and as a first-year plant parent, I honestly couldn’t be happier with my choice. From the moment it arrived, the quality and attention to detail were obvious. The cedar wood frame feels incredibly sturdy, and the pre-stained finish gives it a beautiful, modern look that fits perfectly in my outdoor space. What impresses me most is the durability. It’s Pro-Tect™ tested to handle up to 4,400 pounds of snow load and winds up to 100 mph, which gives me huge peace of mind—especially with the included 5-year warranty. The commercial-grade 4-wall polycarbonate panels really make a difference, too. With my heater running, the greenhouse stays extremely warm, and I’ve already noticed how much better my plants are doing in this well-insulated environment. The built-in ventilation system is another big plus. The temperature-activated exhaust fan and two easy-open windows keep the air circulating and help maintain ideal growing conditions. I also love the thoughtful interior layout—86 square feet of space, a built-in workstation, and over 23 feet of shelving make it easy to stay organized. The PowerPort™ with electrical outlets and USB ports, as well as the interior and exterior hose hookups, make daily watering and using accessories super convenient. Assembly was straightforward thanks to the pre-cut, pre-drilled pieces and the step-by-step instructions on the BILT® app. Overall, this greenhouse has been hands down one of the best investments I’ve made for my plants. It’s durable, functional, and keeps my growing environment perfectly warm. As a new plant parent, I couldn’t ask for a better setup, and I highly recommend it to anyone looking for a reliable and stylish greenhouse.

I built my Willow solo!

I purchased my Willow 9x6 greenhouse in July but waited a few months to build it. It was too hot here in southern California to comfortably do that kind of work in the summer. In the meantime, I put Penofin stain & sealer penetrating oil on all the wood components. All the parts arrived in perfect condition. As a 65 year old woman (able-bodied with fairly basic DIY skills), I am proud to say that I constructed the entire greenhouse myself -- zero assistance from anyone! It's my first project as a retiree. The instruction manual is detailed and well illustrated. Whenever I was not precisely sure about something, the BILT app clarified the situation. I mostly followed the instructions closely. The exception to this was roof construction. Because I was working solo, I couldn't build the roof and then hoist it into place. Instead, I simply first installed the purlin cleats and rafters and then attached the purlins to them (a much easier method, I think). My Willow is anchored to a foundation of pressure-treated 4x4s that are attached to 8 buried 29-lb concrete piers (metal straps shortened with a hacksaw). I made the floor of square 12-inch concrete pavers and gravel. The most difficult aspect of this project was installing the metal splice covers and the metal trim around the edge of the roof -- they lack pre-drilled holes and I'm not particularly comfortable standing on the fourth rung of the ladder. I am thrilled to finally have a greenhouse! It's something I've wanted since I was a kid. After over a year of shopping online (investigating all the possibilities for small greenhouses), I decided to purchase the Willow because it had consistently excellent reviews that mentioned the quality of materials, clear instructions, and attentive customer service (I didn't have to consult customer service!). Although the price has increased by $200 since I purchased mine, I still think it's a great value. Now, I'm excited to fill it with plants. In the summer, I expect to need to cover it with shade cloth.

Sturdy and beautiful greenhouse

we bought this for garden starters, herbs, and to keep our lemon and lime trees (planted in 55 gallon trash cans) during the winter time in Oklahoma. Beautiful cedar wood, extra thick poly panels. Following the construction instructions through the BILT app is a must and easy to follow with 3D pictures.

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.
