I put this together in one weekend including laying the foundation.   I attached it to landscape timbers using long screws and dug them into the ground.  IT is secure and will not blow away.  The instructions have no words so you have to be visual and look at the pictures of what to do, but it is in order and at the top of the page it shows you what parts will be used and which screws.  Not hard jsut time consuming. I am using this to protect my citrus and Plumeria plants over the winter.  We can get down to the high teens overnight and in the 50's during the day.  It looks great in the back yard.
