SimTower Cheats

To build a two-story lobby, start a new tower. Now, select the lobby tool. Hold down the Option key and place your lobby on the ground level.

To build a three-story lobby, start a new tower and select the lobby tool. Hold down both the Shift and Option keys and click to place your lobby on the ground level.

Note that this will only work if this is the first thing that you build. Also, it does not work for Sky Lobbies.
