Due to the high volume of shed and cabin orders, we are not able to take new greenhouse orders for this summer (we build these as a seasonal item).

We apologize for this inconvenience, but if you want to be put on our list of customers for when we build more, please let us know by email or phone. We expect to build more greenhouses this fall or for sure by winter so you can use it early next spring!
