A little tip for people, but it may of course be quite obvious too. I ordered a ramp to be built today which I thought would actually cut into the cliff above, but it doesn't so I have it sticking out so that you have to walk up the screen to go up and it takes up a bit of space.
It was only after going to another island I saw that someone has placed theirs left to right in line with the cliff above. It obviously takes the same space up, but it looks less intrusive and I really wish I'd realised this was possible. I'm dreading how many bells it is going to take to correct. I'm already deeply unhappy with the placement of most of my buildings.
