It would certainly be easier to change the POV program to remove those
limitations than it would be to get it to produce wireframe renderings
of things like isosurfaces and blobs.

Instead of the object pattern, you could difference the building with a
thin box. The textures from the original building would only appear on
the faces that are perpendicular to the camera, and therefore invisible.
difference {
box {<-100,0.1,-100><100,0.1001,100>}
object {House}
pigment {rgb <0,0,1>}
finish {ambient 1}
}
// white bits seen through the hole
plane {y,0 pigment {rgb 1} finish {ambient 1}}
