Build the triangular "User 4" castle supplied in the game. After building it, go to "Extend Castle" and make the castle SMALLER! It should consist of one small back wall, having small round towers at both ends, and a small wall extending from each tower and meeting at a gatehouse with a small building inside. Click on "End Design Word" to build it, and then immediately raze it. You should now possess around 60,000 tons of stone and wood for buliding materials.
