I wish there was a true place for the fridge in the kitchen. When previous owners put on an addition, that moved the fridge to the other side of the room so it's just sitting there, at the end of a counter. I also wish there was some way to flush out the big honking radiators so the house was warmer. Oh and the built-in cabinets and bookcases that encompass one entire wall of the TV room? Not loving them so much anymore as, between that wall covered in cabinetry, one wall all windows, and another wall not there, just open to the next room, there is exactly ONE WAY to arrange the furniture.
I hate that we haven't gotten to many of the things we thought we'd "fix" in our 115 year old house. Rooms need painting, carpets need replacing, and there is just SO MUCH STUFF in here. We haven't even truly unpacked, so the spare room in the basement is full of boxes from our last move- 15 years ago.
