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.

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!

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.

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!

Great Greenhouse

Its a great kit with lot of parts. It took about a week to complete. It takes a while to sort out the parts and put them in order of build. Make sure you take your time, I rushed a few steps and had to redo them to make it right. Read instructions closely .

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.

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.

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.

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.
