I love the unusual shape of my master bedroom. It makes the room and I love that it isn't just square or rectangular like the rest of my rooms. Oh, and I love that I have arches between my living room, dining room, and kitchen; gives some shape and character to my main floor since they are the only rooms on it and otherwise it would be a plain ole rectangle.
That my husband is building it himself from the ground up. We hired out the foundation and will hire the drywall. Everything else is all him and his dad.
Hm... not a whole lot. Our deck is twice the size of everyone else's in the neighborhood, so we get compliments on that. People also tend to love my obnoxiously bright blue door.
That's tough. Inside it's our stone fireplace. Once our LR is in order, I'll post pics in the house bio. Outside it's our backyard. There's a multi-acre tree buffer between our house and a private club which means no backyard neighbors.
