question about Zach's art

[unavez18]

Hi, just joined today although I've been lurking for a few weeks.  This has probably been discussed already since this movie came out a few years ago, but I just stumbled upon it this month (yay netflix!)  so in any case I was just wondering:

Is that Shaun/Gabe's house in Zach's mural?  The one that looks like it has a figure standing in a doorway?  Does anyone know more about his mural?
Just curious.
