I find certian rooms seem to identify strongly with certian elements.
FIRE
*Kitchen
*Lounge
WATER
*Bathroom
EARTH
*Garden
*Cellar
AIR
*Conservetry
*Attic
Bedrroms take on the element of whoever sleeps in them. My room is shared with my younger brother. While I'm air and water, but he is fire and earth, so my room is a very ballanced place.
I'll post more soon. :D
