Very special thanks to Alexandra in NH for sharing these terrific step by step photos of her very beautiful 
Cedar-Built Lean-To.  What an awesome ocean view as well!

Day 1:  (Oct. 09, 2003) " We have the "bones" up.  It went up really quickly once the guys got in the swing of things - they  were really impressed with the bit attached to the instructions! 
 I think the guys began the project a bit skeptical about a greenhouse kit, but each one has said to me individually how well made it is and how organized the pieces are! 
Hooray for you all!
The smell of that cedar is sooooo nice!"
