Suburban Zombie Dog-Walking Lady, Part 3

I have discovered the lair of the zombie dog-walking lady. It's at the furthest point of my walk before I begin the loop back. I have varied the timing of my walks (more by accident than design) and--arriving early one morning--discovered it standing by the circular drive, still, unmoving, looking for all the world like a giant, white, overweight, female jockey boy statue holding the reins to the dog. (So, just like one of those obnoxious jockey boy statues except for the giant, white, overweight female part.) It did not move an inch as I went past.

The house is strange but in a very subtle way. It is single story, as so many others in the neighborhood are, but with a roof that rises to the level of a two story structure without gables or skylight. It also has a half turret appendage attached to the back. (The back abuts an empty lot which in turn faces another road that is part of my walk so I can, between the two see the entirety of the place.) It can not be hollow under those huge eaves. No one would be crazy enough to heat or cool all of that empty space.

Since no house in south Florida has a basement, the water table being far too high, the only logical conclusion is that the reanimation lab is tucked up under the roof, invisible to the casual observer.

I have never seen lights on in this place, nor a car in the driveway. Since any closer inspection will involve either deception or trespass, I am not sure where to take the investigation from here.
