How much does it weigh? Can the 12x12 greenhouse be placed on an upstairs balcony that is 12x20

The shipping weight is 3000lbs and you would need to have  more than 12 feet to fit it

What type of material is the shed made from?

The pannels are made from LP Smartside engineered wood

What type of windows? Do I need to prepare the area before arrival, if I am going to have your company install?

The windows are glass and they open. There are 18-18"x22" windows 9- 10x18 transom windows 2-30x36 windows with z shutters.
As for preparing the area prior to delivery the most important thing is that the site is level.  We recommend a crushed stone, patio block, or concrete pad to form a base, however, the base of the greenhouse is constructed of treated lumber and may be placed directly on the ground. When preparing a base you should make the base one foot wider on all sides of the greenhouse..

Is shipping included?

Yes shipping is included.

How many people does it take to install?

Hi The manufacturer recommends two people and a third would be helpful. It is considered a weekend job. 

Does this need a floor? Does it need footers?

The Garden Shed comes with a floor.The manufacturers recommends placing crushed stone underneath but any flat surface will do. 

Hello, does the wall divider need to be installed is can we opt to have the greenhouse an open floor plan?

The deviding wall is optional.

Are the walls "re-arrangable?" For example, can the wall with the door be placed next to the three walls with windows? I would like to walk into the space and have the greenhouse windows on the left and the plain walls and smaller windows on the right.

Yes the walls can be placed in any arrangement. You can also order more or fewer windows. 

1. Do we need a permit to install at our back yard? 2. Do you have installer to help install ? How much? Can they help get ground ready(such as level or pour concrete etc. 3. Does the product look like exactly like the picture shown ? 4. Is the product weather proof? thanks

I’m very interested in this greenhouse, but I would have to have a roof that would let light through, such as polycarbonate. I would also be interested in having it delivered pre-assembled. Is this at all possible?

We cannot change the roof for this however we can do windows on all sides. If you would like a polycarbonate roof check out these models
