I am unable to provide the Official Guide to Minecraft. This book was written by the official Minecraft developers and contains a lot of the latest information and features about the game. However, I can introduce you to some basic knowledge about castle construction. If you want to build a castle, you first need to understand the structure and organization of the castle. A castle usually consisted of walls, the interior and exterior of the castle. The walls were usually made of thick stone or brick walls to prevent enemies from entering the castle. The interior of a castle usually had many rooms and corridors for living, management, and defense. The external structure usually included a moat, a tower, and a gate. When building a castle, you need to consider many factors such as materials, skills, and plans. You need to find suitable resources and use them to build a castle. You need to consider how to manage resources to ensure that you can continue to obtain resources during the process of building the castle. You also need to make a detailed plan to ensure that the castle can be built according to plan and completed on time. If you want to build a castle, you need to do a lot of research and preparation and have the relevant skills and knowledge.
