The house shown is a Lantana and a couple of my friends have done the same in their Lantanas...made that dining room area a sitting room.....both look great.
Don't worry too much about decorating, your home will be lovely, and not because of the furniture, but because of the people who will live there...
Mike and I are in the process of trying to pick out new flooring for our three bedrooms and my neighbors, friends, have been so sweet, letting me walk through their homes, check on their flooring choices, sharing how much they paid, who did the work, etc. Each home was decorated so differently, and all were so lovely!!! Of course I know I have the nicest neighbors in the world...
Enjoy, it's going to be fun, fun, fun!
