And here is a drawing of what the new area should be.

The mansion is to be stone-based, with stained clay spires. It is supposed to be a rich mans house, so not ruined or anything. Make sure it is merged into with the terrain, and when you create the overhang please make sure you have my exact guidance. If you have any more questions, do not hesitate to message me. Please clear out all spikes and edit terrain so the mansion looks good. Don't worry about it being on the map, the area you are working on is off-map.
