Rees, pretty much if someone has an idea of the way they want to build a condo, we'll build it. We have a section here that some people post their ideas and I like most of them too.
I'm waiting on this house dealing thing to settle before buying anything for now, even a few bags of crete. I sold or gave away my lawn service co. today, getting to old for that hot work. I have some 4" pvc, 3 to 6 foot pieces. I'm looking for more. I can set them in concrete for some boo condos. Another idea, dig a hole about the size of the milk crate. Drive a stake into the hole at different angels place the boo into those holes then cover with crete and water. Different ideas of the way to build them won't hurt anything. Have a bunch laying down and some standing, all will work.
