The LotExpander will not be updated for Apartment Life.


This is the final version of the LotExpander. It has been superceeded by the LotAdjuster:

This version of the LotExpander works with all expansion and stuff packs, up to and including The Sims 2 Free Time. The latest release resolves an issue with continuing after an abort. Please see "Known Issues" below.

The LotExpander allows you to expand "The Sims 2" lots up to a size of 6 x 6 with a few mouse clicks.

To install, just download and unzip it. Run the EXE from the unzipped location. This is "alpha" software and is still in development; it is not guaranteed to work and may corrupt your lot. Be sure to backup your game before using this tool.

I have included the source code in There is no need to download this file unless you are a C# programmer who wishes to look at or modify the code.

- The program uses some DLLs from SimPE; they are included in the zip file.
- LotExpander is released under the GNU General Public License.
- You need the Microsoft .NET Framework 2.0 to run the LotExpander:

Known Issues:
1) The LotExpander sometimes does not work with Vista. There is no known solution at this time.

2) When moving a pool with rounded edges, the rounded edges will not move. For now, just delete the rounded edges before expanding the lot and add them back to the pool in the new location once the expansion is complete. If you accidently expand a lot without removing the rounded edges, the lot can be fixed using the normal build tools; however, it is more difficult than just removing them beforehand.

3) The expanded terrain takes its form from the terrain at the edges of the existing lot. This does not always produce the desired result, especially for hilly terrain and beach lots. I am investigating whether the LotExpander can use the actual neighborhood terrain for the additional land.

Please see the LotExpander tutorial at:

If you have any problems with the LotExpander, please let me know.

Small Lots:
Now everyone can create lots of whatever size they wish with LotExpander. Here are links to expandable lots which are 1 wide or 1 deep, and which have the sun shining on the back of the lot:


If you prefer the sun to shine from the front of the lot, take a look at aelflaed's brand new sunnyside lots:


And here are some North- and South- facing 2XN lots:

This program was designed and developed by Andi8104. He really deserves most of the credit for the LotExpander. I have been making minor changes to the tool since Andi died. The original tool is still available at:
