This will probably be the 2nd achievement you get. Players who have played this game on the Windows Phone will unlock it once they select their existing village.
For the other that haven't played it on WP yet, you need to build habitats and farms. By doing the quests, you will build a couple more of each. Besides, when you have a few thousand gold you can select the gold coins on the bottom right side of your screen, and build more buildings and habitats from there. A fire habitat only costs 100 coins, so whenever the limit for habitats is raised, you can get the achievement with only 700 coins. You should get this achievement by natural play though. I got it around level 7-9, so it will unlock pretty fast, after you've started the game.
