Exceeded Expectations!

We’ve wanted a greenhouse for years and finally found one with the looks, functionality, and price we hoped for. The service was excellent, materials of great quality, instructions easy to follow, and assembly totally possible for an older couple to manage by ourselves. (We have some construction experience.) The fan with thermostat works well and the interior is customizable for our needs. We love it and are so glad we got the Bellerose.

Incredible!

It’s an incredible greenhouse. Everything is so perfectly formulated to fit together when you build it I was so hyper impressed with the quality and function of every piece. I would buy another one again in a heartbeat, although I’d probably hold out for their biggest model because as soon as you get a little bit of space, you wanna fill it up really fast.

Greenhouse

Best greenhouse ever. This is my 2nd greenhouse, but so wish I would have found this a year ago, before I purchased my first one. Very sturdy and well made. Took me and my husband about a week to put together. But we took our time. We are retired. The only thing we needed help with is put on the roof. Need a couple of strong guys for that. We laid everything out on the ground keeping each board in stacks , by alphabetical order. Screws, nuts, bolts etc. Kept in order in a box. The instructions were actually easy to follow. Couldn't ask for a better product.
