Hi, a little introductory my name is Nathan, and I'm starting to build greenhouses. My design is that of the classic grambrel (barn shape). The dimensions are 8x8 and 8x12. The 8x8 is $1400 and the 8x12 is $1600. It is built with a wood frame with pressure treated on the base. It is then covered in clear corrugated PVC siding. (I have included a picture of the corrugated pvc) In the front there is a wonderful regular sized entry door and in the rear is located the ventilation door. Inside there are cedar slatted benches on both sides for you to put your pots and flats. Thank you for looking. And give me a call for any customizations. 1 541 990 1728 Location: Redmond it's NOT ok to contact this poster with services or other commercial interests oregon
