I would do it in this way:
Let's say there are two tables building and room_detail. Let building
be

Let room_details be:
db.define_table('room_detail',
Field('detail_key', string),
Field('detail_value', string),
Field('building', db.building))
For every new information for a room, you can use a new record with a
distinct detail_key like 'name', 'owner', etc. Further, every
detail_key can be a value from a lookup table like
'room_detail_lookup' which contains the superset of all possible
detail_key values:
db.define_table('room_detail_lookup', Field('lookup_name', string))
OR use a validator in the room_detail table:
db.room_detail.detail_key.requires = IS_IN_SET(['OWNER', 'NAME',...])
Hope this helps.
