Minecraft wiki entry for Blueprints, associated text: Taiga villages use spruce wood, Savanna villages use acacia wood. There are acacia logs instead of cobblestone in savanna villages except the blacksmith, church, and around the well. Desert villages have sandstone based variants of all the buildings substituting regular sandstone for cobblestone or wooden logs, and smooth sandstone for wooden planks. Wooden doors and fence posts are still used despite the lack of wood sources. Desert blacksmiths still use stone slabs on the roof. Also cobblestone in the church, the blacksmith and around the well is not replaced with sandstone.
