Do's and Dont's For Facilities on Private Property

I recently bought my first home and for the first time I can build a mew and weathering yard that won’t have to be moved after just a few years. I’ve always had to just adapt to the situation I was in, and be ready to move. I could really use some input from falconers with permanent or semi permanent faculties built on land they own or have owned. What kind of foundation did you use? How have your facilities impacted your property value? Have neighbors complained? Did you require a building permit? Whats something you wish you’d thought of before building? I know this kind of thing is super situational, but that’s exactly what makes it hard to find info on. As always any input is appreciated, happy hawking.
