I'm seeing coincident surfaces in the window, and doorway too, I believe.
Better scale those cutout boxes slightly upward in the facing direction,
translate slightly too if a side is on a zero plane.

Sandstone could be done by using a very small scale granite normal but it
wouldn't show up on a unlit side.  So a texture layer of granite pigment and
normal both over the one you have now would be better.  Just use a small enough
scale.
There's probably a sandstone in the stones.inc file already but not everything
is labeled enough I think.

I added a sandstone into that file (just looked) but since I changed much of
the naming scheme I'll just put a stand-alone one here for an example:

sphere {0,3
texture {pigment {rgb <1.2,.9,.4>}
 finish {diffuse .9 specular .1 roughness .1}
 }
texture {
pigment
 {granite
  turbulence 0.4
  color_map
   {[0.0, 0.1   color rgbf <0.8, 0.5, 0.4, 0.0>
                color rgbf <0.8, 0.6, 0.5, 0.6>]
    [0.1, 0.3   color rgbf <0.8, 0.6, 0.5, 0.5>
                color rgbf <0.9, 0.5, 0.35, 0.3>]
    [0.3, 0.5   color rgbf <0.9, 0.5, 0.35, 0.1>
                color rgbf <0.85, 0.7, 0.4, 0.0>]
    [0.5, 0.7   color rgbf <0.85, 0.7, 0.4, 0.0>
                color rgbf <0.8, 0.75, 0.5, 0.2>]
    [0.7, 1.0   color rgbf <0.8, 0.75, 0.5, 0.3>
                color rgbf <0.8, 0.5, 0.4, 0.0>]
   }
 }
 normal {granite .5 turbulence 0.4}
 finish {diffuse .7 specular .1 roughness .1 crand 0.1} // use zero if
animating
  scale .8
 }
}
