I download houses from the gallery and place them unfurnished, then decorate them. I absolutely adore interior decorating but don't have patience for the exterior (minus the backyard). I've only built one house and it turned out with a horrible floor plan. Maybe I'll do a remaster of it someday.
All of the above except for living rooms! I redecorate the interiors of gallery and Maxis houses a lot, so I've found joy in decorating every room... except the living room. I don't know why but I can never figure out where to put anything in it!
I can't post links/images yet, but I'll add a suggestion: Divided/two side/two-d-one-f sinks. They could literally just reuse existing in-game assets and I would be in love. Just ctrl+c the drain, move it to the left, ctrl+v on the right, ctrl+c the sink's side, slap it in the middle, then cut down the length a tad it do…
