Mt. Hood models are six feet wide with plenty of headroom at 8'-4" tall at the peak. Narrow enough to fit in a limited space, each kit is made with a clear natural redwood frame, twin wall polycarbonate and includes two vents with automatic vent openers, Dutch doors and a base made with recycled plastic. With up to four optional benches, you can optimize your space no matter what you want to grow. If you are not sure which size is best, remember you can extend the both the 6' x 4' and 6' x 8' model at a later date by four feet with our extension kit. With our pre-assembled panels, you can easily assemble your GardenHouse in just a short time--a 6' x 8' model, one of our most popular, takes two people about three to four hours to complete. Each kit includes easy to follow printed instructions, clearly labeled panels, as well as an assembly video.
