We constructed this last summer.  Happy to report how it has withstood some heavy wind storms.    Would argue that it could be constructed by only 2 people (maybe if they were very tall).  4 workers is what worked for us.  Very happy with detailed written and digital instructions.  We understand it met minimum code requirements, but a little beefier construction would have been preferable.  Looking forward to adding gutters and rain chain as well as light & fan fixture this summer.  Thanks for a nice quality product.
