I was building on Plot 24 untill I realised that something was off. My character was floating. Not gamebreaking but certainly immersion breaking. I fixed it by using boardwalks to my house and heighten them but somehow it looks off.
Also logged on with another character but still the same thing. I tried to lift my house and then brought it to ground floor again. Maybe this is what causing it?
Same plot same issue,deco is floating and so are you and your visitors :> Place your house far behind and have entrance facing towards coast for now. The good thing is about this plot, i kinda marked its outline early on with trees and towards the oceanside it expanded a little bit as if it grew 
I had the same idea! What I just did is put a lot of boulders on the far corner towards the sea and put my house on top of it. Then build ramps with platforms leading to it. I intend to make a viewing platform looking over the sea. So like you my problem became something great. Still, I hope Blizzard keeps the air elementals in check on this plot
