The wall you don't see in the (blue) office will have folding doors so we can make use of the big closet.
MBR - we'll be taking up carpet to expose hardwood. No plans to paint but that could change.
Family room - we are getting rid of fireplace to make clean corner and pulling up carpet. Probably doing cork. E will have wooden kitchen and play area at the part of room closest to kitchen -- the full width from where carpet currently starts to under extra AC unit, I think.
We are going to take down the wall separating DR and LR (have to move structural beam) to increase open flow.
Paint in E's room will be either pale blue or both blue and yellow.
We plan to have an art &craft area for E on the "wood" floor in the finished half of the basement. Carpeted area will contain our current basement office furniture. There will also be a futon for spillover guest (I didn't include photos of the currently pink but will be peach guest room on the main level). We might also give E some floor space for trains.
