Harvest Moon: Save the Homeland

To obtain this, you simply have to spend 15,000g to buy both the Kitchen extension for your house, as well as the Dog House addition, both purchased from Woody's Construction hut in the forest. The trophy won't appear until after you've seen the cutscene cinematics where the crew informs you of the new changes. Unlike most HM games, this one simply requires a day to pass before the upgrade is completed.
