TMF-2 > The Mansion Family - Vol. 2

[Toybox]

You could build a second file starting in Jack's house, and when you get up you can go right or left:

• to the left there is, as you suggested, the proper new mansion;
• to the right there is one room in common with TMFV1-TMM but you add something which blocks the way - a car, something.
  

As for further TMF mansions: don't forget Jack can go out through a perpendicular street too
