Yes, we have a full, finished basement. LOL, I actually don't consider it a basement as we spend most of our time down here.
My DH did all of the work himself, it took a long time but was way worth it. Half of it is an open room with the family room (a wood burning stove, TV, couches etc) at one end and the other end is my 'office'', computer desk, filing cabinet and walk-in closet.
The other half of the basement is divided by my eldest DDs bedroom with a walk-in closet, a full bathroom (which she 'claims' is hers) and the laundry room with a door that goes out to our patio. It doesn't feel like a basement because only 2 walls are under ground.
Also, we wanted to the two levels to flow together so you wouldn't feel like you were leaving the 'living space' to go down into a dungeon. We have oak hardwood floors upstairs, so he opened the dining room wall up and put in an oak railing and staircase so that the rooms sort of blend and the downstairs is more inviting. (if that makes any sense)
I love having a basement, I have never lived in a house without one. We use the attic for the 'junk'.LOL...
