What we need to see here is the house ON the site. It's a little worrisome (for me anyway) that the parts of the design BEYOND the exterior walls aren't being designed the same time as the parts WITHIN the exterior walls. Everything should be designed simultaneously, especially since you're going to have a pool with a pool house. Figure out where that stuff is the same time you're figuring out where the master bath is.
Design of a project should stop at the property lines, not at the exterior walls. Here's some examples:
But good luck with your project. Exciting times ahead!
