Depends very much on the region/country/jurisdiction/county you're living in.

Walls are your's? Not when it falls under some heritage laws/building codes which forbid too much deviation from the original.

As much solar as you want? Again, very much depends on not disturbing someone elses view, or the 'general character' of the surrounding landscape. OFC again dependent on jurisdiction.

Big bad antenna? See above. Cats 'n dogs, again dependent on country/county. The same for tree.

All of this applies to some regions only, where your next neighbour is far away, out of sight, usually.

And even then you can have shit like 'water rights', like in Colorado.
