Due to some recently-discovered mold issues in our 3-bed, 1-bath 1950s cottage that mean we're going to need to do some serious remediation work. Since we likely need to replace most of the walls and ceiling on the back half of our house, we're considering whether to use this as an "opportunity" to do some other renovations.

So of course to kill some time while I wait to hear back from various contractors, I thought I'd mock up some (very rough) floorplan ideas...

Essentially, the options I came up with would close up the pass-through from the kitchen to the den to create a room that could serve as an actual bedroom, convert our smaller bedroom into a second bathroom, and relocate our stacking Washer/Dryer from the kitchen to closer to the bedrooms (giving us back some much-needed pantry space).

Anyone with a better eye for layout than me think these ideas are great or terrible, or have suggestions for ways to tweak?
