Choosing an appropriate design & function for your greenhouse will be a major factor in determining it's size. Will your structure be used for propagating or housing a collection of plants or flowers? Will it be used for something entirely different such as an aviary, a spa, an exercise room, or a little retreat?
 
Each greenhouse is made to order, allowing a greater freedom in style and features. Our framing and glazing options accommodate your individual needs and tastes.
 
Sierra Greenhouses come in 3-foot increments. Choose from the standard 9x6, 9x9, 9x12, 9x15 or wider versions; choose from a 12x12, 12x15, etc. You determine how small or how large your greenhouse will be. 

Please note: Greenhouses larger than 9x12 may need a building permit.
