don't know if I unterstood you right, but what about buffering your
polygons (v.buffer with buffer=50m), i.e. the buildings. So you get a
map of overlapping areas where features not more far away than 50
meters. Afterwards you can use v.to.rast for rasterizing the buffer
zones and describing small towns for you case.
