I have expanded all of my rooms apart from the left room as it's my own little bedroom & I like it to be a lot smaller. ^-^ I feel that if I was to have it at the biggest expansion, I wouldn't know what to do with it.
In my old town I had every room but my left room upgraded. I had the cardboard set set up in that room and since it's a really small set, the medium sized room offered the perfect amount of space. It was my favorite room in my house by far. Now that I've upgraded my new house fully I feel like the intimacy and perfectness of that room is lost even though I kept the same layout and just filled in the space between the wall with snake plants and rubber trees.........
I've got my main, left, right and 2nd floors fully expanded. My basement is medium sized and a children's room, so the size is just perfect. I think I am going to fully expend my back room too.
I haven't fully upgraded, nor do I plan to. I like the side rooms, upstairs/downstairs being on the cozy side, and adding a back room throws the main room off-kilter, IMO. Right now I only have the main room fully upgraded (creepy/classic combo), a basement kitchen, and an upstairs bedroom.
I've fully expanded my mayors house and currently have 4 rooms (out of 6) furnished (I have pave, modern, harvest and balloon sets). it wasn't cheap for sure...
but now I have 3 other houses to expand, I'm progressing there but slowly because them loans aren't easy on my poor pockets lol
I've only got 2 more payments to make on my house. After that I'll either upgrade my alt's house or save my money and buy Gracie items.
Although my house is nearly complete I don't really have any furniture to fill it with
