House Expansions
From Wild World Wiki
When you first start playing Animal Crossing: Wild World, you will think your house is a little claustrophobic to say the least at only four squares by four, giving you enough space for sixteen items. Your house also has a save room upstairs which is 6x5 squares in size, but you cannot use any of this space for storing items and the room cannot be decorated. Regardless of what you think of it, you must pay off the mortgage. To upgrade to the next house you must pay off 19800 bells.
The first expansion is added on as soon as you pay off your first mortgage and tell Tom Nook that you want an upgrade. After a night's work, your house's first floor will be much larger than before at 6x5 squares in size, giving you 36 itemsworth' of space. This will come at a price, however, and you will cost you 120000 bells.
When you have finished paying off your second mortgage, Nook will offer you the second expansion. This is again an increase in the size of the first floor, which will make the room 8x8 squares (64 item spaces). This is as big as your main room gets, and the mortgage for it will cost you 298000 bells.
The third expansion will add another floor to your house, slipped in between the first floor and the save room. The save room is still the top floor, but now there is a 6x6 room on the second floor that you can use for storing another 36 items, and you can also decorate it as you see fit. This second floor will come with a mortgage of 598000 bells.
Expansion number four will add a western room to the first floor of your house for a mortgage of 728000 bells. The new 6x6 room will lead off from the bottom left corner of your main first-floor room. This room is not expandable, but can be fully furnished and decorated.
The fifth expansion will add a right wing to your house identical to the western one added in expansion four. The mortgage for this expansion is 848000 bells.
The sixth and final expansion is the addition of a back room to your first floor. This room is again 6x6 in size and fully customisable. Once you have paid off the 948000 bell mortgage, you are free from having to expand your house ever again.
