Oh, I love your greenhouse! I am one of those not familiar with blueprint so it will be fun learning about it. Oh, I remember glass floor tiles! I loved them! Those would be worth finding. Thanks for all the helpful hints and letting us know of alternatives when we don't have a specific object. Really great idea saving the greenhouse for future use. :)
Your summer house project sounds like fun. Not only to you get to recreate it, but you get to relive the memories in the process. I can see where CC would be the only way to go. I think you will be much happier with the results doing it that way. That's really special that your dad built it. Do you know if the house is still there?
