tricks of the trade
if you are new to the game, try building your house out of the side of a mountain or a hill, if you chance upon a cave they are very good for houses, however you must remember that caves are not always one single cave and are more often than not connected to a cave system. This technique will allow you to expand your house with relative simplicity, it also requires minimal resources as the walls and roof do not need to be built. Once you are finished digging out your house and are content with the size you can start decorating it. Remember to light your house, if you have built it underground then there is a very slim chance that you will be able to create windows.
