This seed spawns a Woodland Mansion so close to your spawn that you only need to look slightly to your left to find it behind some trees. This seed is awesome not only because the mansion is incredibly close, but also because it's cut right into a mountain -- giving you a great place to start a mine and farm the materials you need to take on the evil villagers inside the mansion.
Note that this seed requires Minecraft PE 18.104.22.168 or later. You need to sign up for the beta to get these releases. Android users can do this via Google Play.
