The 6' x 12' Kennsington Greenhouse is the only unit on the market with easy access doors in the front and the back. Finally it’s simple to move most wheelbarrows or garden carts (24” door opening) through the greenhouse, picking up and dropping off soil and plants without reversing direction. It also makes it more comfortable for two people to be working inside at the same time.

The Kennsington Classic 6' x 12' kit uses a patented push-lock interlocking frame system and features rigid polycarbonate panels that are 4 mil. thick and twin walled for maximum insulation. Panels simply slide into place and become part of the rigid frame system, which includes an air circulation Smart Vent in the wall.

Assembly Note: This project will require 1-3 days with 1-2 people systematically following the assembly manual. Two people make the project easier and more enjoyable.
