So I have my base, and the enter key doesn't work on these forums. Anyways how can I extend it to make it look more aesthetically pleasing. Im not going to include pictures because everyone screams at me about lighting and the roof. in my house I have 1 hall but at the end of it is my piston room with some extra cobble chests in there. Im not extending from there! EDIT: Fine. Heres the pics. Teeny bit outdated but so what. https://www.dropbox.com/sh/5r29pwmbhr6mycd/Pn_aW4Mh5n
well, the only way to expand is making passways from the hall, maybe some branches? or make more floors and try to make then spacious and then hide the dirt/cobble/stone with some wood or any material you wish. I guess this is all i can give unless we get picture.
Try making a new world, and build a copy of your house on creative. Build something, and if you like it, go back to the main world, and build it there on survival. I have done that before, and it works. I hate building something, and hating it. Then I have to tear it down.
If you have access to the Nether move your portal into your base. If you have done this get some glowstone and make an underground farm. That way you will never have to leave. Make sure to include trees and cows. Also, try to get some screenshots.
