We've got plans to redo the bathrooms and the kitchen in our house. We've already done a kitchen before, so we know what we're up against. There won't be any change to the floorplan, just new and updated materials, so it's not that bad.
The master bathroom -- I want to bump out the shower area into the eaves over the garage. There's a huge amount of space back there, and with a little finish-work, it could significantly expand the storage capacity of the master closet as well.
Oh, and re-carpeting the upstairs and the den.
These will be on a reasonably tight schedule. We will be getting professionals for all these projects.
