I guess we have a bunch of neat features, and one in progress. I'll only inflict a few of them on you!
The end of our kitchen island faces the dining area and we put a TV inside that end of the island.
DH built a 17 foot, stone, Rumford style, wood-burning fireplace in the livingroom. The fireplace divides the living room from the kitchen/dining and you can walk around either side to get to the kitchen/dining. On the back wall of the fireplace that faces the kitchen, the center is brick with a bordering arch of stone, and we have a cast iron woodstove hooked up there. The woodstove heats the house very nicely. We have another in the walkout lower level and the furnace hasn't been on all winter.
In progress: Dh is building a tunnel walkway that will go from the house basement to the basement of our detached barn/garage, about 50 feet away. The top surface of the walkway will be a sidewalk to the 1st floor side door.
We have a little outbuilding that looks like something from Frontierland. It has wood siding, old mullioned windows and door, and a "loading dock" along the front that has a bunch of antique crates and barrels, and an old fashioned park bench to sit on while you wait for the stage coach!
