Hi! I just built a rose garden that is inspired by a park in Berlin that I went to last summer!. I also build other stuff in ACNH and is currently building a channel on it!
i was feeling this too. but then i quite noticed that islands/maps that seem to be much bigger than mine.... they just used their space carefully. or in other words, made sure to have each & every space to be useful as possible. i noticed the walkways are minimum to 1-2 blocks, then there's not really a lot of flowers or items aside from spaces where they want it to be. basically keeping the spaces minimized because a single line of fences already affect the size/space to use.
