I'm planning to finish my basement. My house is only 4 years old, the
basement is concrete walls & floor slabs. The previous owner framed &
insulated most of the walls, two walls remain un-framed.

The basement has one main room, with a bathroom and utility room
(furnace & wash/dryer). The bathroom door is in line with the slider
to outside. My floor plan was to have large tile floor in the
bathroom, but use the same tile in the main room for the portion that
connects the slider door and bath room door. The rest (85%) of the
main room would be carpet. The utility room also would be tile.

Not sure how well this will show up in google groups, the dots are
tile, equalsigns are carpet:

Not to scale of course but my point is that the main room will have
two different floor types (carpet & tile). Whats the best approach to
finish the floors?

Also, do I finish framing the walls first, or do the floors before the
walls? Or do I drywall the walls / ceilings THEN do the floors? Thanks.
