Here is a link to my thread showing how I made this house. https://www.backyardchickens.com/forum/viewtopic.php?id=2159
We had a storm last spring with winds up to 80 miles an hour and a microburts and the hoop house took it with no problems. The base is 2X4's and heavy so that probably helps.
that makes sense about the base. from this picture i did't know it had a base. probably woulnd't need a base most places but i was just thinking about some of the wind here. i really did't realize that pvc could bend like that. i have some ideas for a couple things around here. what does one tube like you used cost.
