Your Sierra Greenhouse can be built on almost any surface such as gravel, wood chips, cement, bricks, etc. as long as it is level. 

We are available to assist you with your site preparation, in order to assure your greenhouse will assemble square and true. Please discuss this with us prior to your job.

Please Note that Greenhouse sizes are not foundation sizes. Upon receipt of your deposit, you will be provided with a site prep drawing and exact dimensions for your foundation.
