Carpenters (Harvest Moon: SNES)
Since this is the first harvest moon, there are not many extensions. Only two in fact, but they are still awesome! At the start of the game you start with a small log house and you can upgrade it twice!
Super Log House
Gold: 5,000g Lumber: 250
The super log house is the first extension and it only makes your house a big bigger and adds a carpet here and there. If you complete it before fall the carpenters will give you a watch for free. You need this extension to get married.
Super deluxe log house
Gold: 10,000g Lumber: 500
The super deluxe log house is the second extension and it will add one more room to your house and cradle (as well as a cool looking porch).You need this extension to have children. You can also paint it white.
