If you're new to building or just want to refine your techniques, the supplement from the Head Builder of Dawn of the Ages is, IMHO, excellently written and useful for both new and advanced builders. It's focused around the creation of a Merc/Diku-style area, but the general tips given there will pertain to any codebase.

I looked over the introduction and the room description examples and I was impressed at both the terms used and method of providing guidance to improve an obviously lacking redit to an exceptionally good one.

Kudos to those involved, in my opinion it's a wonderful asset for teaching new builders and some with bad habits from the old days.

Psst, wasted, not waisted hehe, can't help it, I'm a builder too.
