At RE minus four months, we went from an 800 sf condo to a 2,600 sf house. It's felt quite empty, and ironically, we've had a hard time finding places to put the last 15 or so boxes of the 6,000 pounds of stuff we actually moved, due to a lack of furniture and bookshelves. Our place still seems empty, but my wife seems intent on filling it up. I enjoyed adding a wall garage cabinet/workbench system, a scuba compressor, and a few shelves in the closets. I wanted a minimalist retirement, but Amazon boxes come almost every day of the week, now. Hopefully, to slow down, soon.
