Nice models, but to me the roofs don't really look medieval -- I'd expect thatch roofing and the such, not shingles.
perhaps hes going from reference photos of the buildings as they are now and very few old houses in this day and age have thatched roofs (iir they jsut dont allow it in the uk due to fire hazzards, but then again i dont go to rural areas so they might be rife with thatched cottages still)
i tend not to take photos of cambridge as its all been done before
the round church however deserves more than the 2 or 3 ive taken over the years
the lepper chappel also
and the windmill in fullbourn needs investigating as ive only ever seen it from a distance on the way to work
the rest is either too modern and uninteresting or photographed 100 times a day and i dont want to be the 101st
