In the link provided is my first ever Minecraft Tutorial where I show you layer by layer, easy to follow allong how to build the Best Survival Base, with everything you need and lots of room to expand, the build includes a crop farm, and has enough space inside to add up to 3 rooms, you can even add levels under your house to make a good size base even bigger. you can stop building on layer 5 if you just wanted a 1 story home.
