Minecraft wiki entry for Half_hearted_hardcore, associated text: When you wake up, you can start building a house out of any easily obtainable material. It is not recommend you make it look pretty because you might get attached to it, and you will probably lose it at some point. Also, safety is a priority, so make sure you light up the house and make sure it is 100% mob-proof and sealed with an iron door. It is recommended you build a wall around the house and light up the area inside and around the wall to keep the mobs out. You will also need to set up a crop and animal farm (if you have mushrooms, then a manual mushroom farm as well), so hunger will cease to be a threat. And make sure to skip the nights, and try not to gather wood from forests (because mobs can spawn in the day), but from the surrounding areas instead. After you're done, you should have an outdoor crop farm, sugarcane farm, animal farm, manual sheep farm, chest room, smelting room, optionally bedroom, and some spare rooms you will need to use later, preferably for brewing or nether wart farming.
