To find and complete the "Tarrey Town" side quest in The Legend of Zelda: Breath of the Wild, you need to talk to the character Hudson in the game. He will ask for certain materials to build houses in the town. After fulfilling his requests, new characters will arrive, leading to the completion of the quest.
Locating Hudson and Starting the "From the Ground Up" Side Quest
In "The Legend of Zelda: Breath of the Wild," the "Tarrey Town" side quest starts with the "From the Ground Up" side quest. To begin this side quest, you need to travel to the East Akkala Stable. From there, head northeast to find a small house on the hill overlooking the ocean, between Akkala Citadel Ruins and the Giants' Forest. Inside the house, you will meet Hudson, who is a Hylian that you need to recruit for the construction of Tarrey Town.
Completing Various Tasks to Build Tarrey Town
To progress with the "From the Ground Up" questline and ultimately build Tarrey Town, you need to help Hudson find suitable personnel. Hudson will ask you to find specific individuals to join the Tarrey Town project. This involves finding a Goron, a Zora, and a Gerudo, who will each contribute their unique skills to the construction efforts.
Recruiting a Goron
To find the Goron, travel to Goron City, located in the Eldin region. Look for a Goron named Greyson who is willing to join the project. Greyson can be found near the southern mine entrance in Goron City. Speak to him, and he will agree to move to Tarrey Town to contribute to its construction.
Locating a Zora
For the Zora recruit, head to Zora's Domain in the Lanayru region. Look for a Zora called Fyson who can be found near the bridge leading to the domain. Fyson will be willing to join the construction efforts in Tarrey Town. Speak to him and convince him to move to the new settlement.
Recruiting a Gerudo
Lastly, you need to locate a Gerudo to complete the trio of recruits. Travel to Gerudo Town in the Gerudo Desert region. Look for a Gerudo named Palm who is usually found walking around the town. Palm will agree to join the project and move to Tarrey Town once you talk to her and inform her about Hudson's offer.
Completing Tarrey Town Construction
After you have successfully recruited all three individuals (Goron, Zora, and Gerudo), return to Hudson in the East Akkala Stable. Once all the required personnel are gathered, Hudson will relocate to Tarrey Town with the new recruits, and construction will commence. Throughout the process, you may be required to provide certain materials and resources to aid in the construction efforts.
Benefits of Completing Tarrey Town
Once Tarrey Town is fully constructed, you will have access to various amenities, including vendors selling rare and unique items, a dye shop for customizing your clothing, and a house that you can purchase. Furthermore, completing the "From the Ground Up" questline and building Tarrey Town is a rewarding experience that adds depth to the game world and establishes a thriving community in the vast land of Hyrule.
