Before actually starting on any proper design work, I thought it might be a useful exercise to identify what it is about church architecture which so appeals to me. From looking again at the numerous photos, I was surprised to see that they actually fall into just a few categories:
1) the juxtaposition of different planes, how roofs, walls and buttresses relate to
each other, rows of wonky gravestones, vaulted roofs etc.
2) tracery patterns, positive and negative shapes
3) stained glass windows
4) adornment, e.g. gargoyles, carvings
5) the fabric of the building itself, i.e. stone, brick, wood and how these are affected
by time
Should be enough material there to keep me out of mischief for a while.
