The Carpenter’s shop is open between 9 AM and 5 PM Monday through Friday. It’s open between 9 AM and 2 PM on Sunday and is closed all day on Saturday. You’ll need to drop by when you want to start construction. Keep in mind that most upgrades take a few days to complete. You can get bronze ore from the Earth Mine, silver ore from the Water Mine, and gold ore from the Wind Mine. After that, your dream home is just a smelt away.
