Tears of the Kingdom does not include a free-form house building system despite its robust construction mechanics. Link cannot use Ultrahand, Fuse, or any other ability to build a player-designed house structure in the game world. Instead, Nintendo provides two housing options through quest lines: you can purchase and furnish a pre-existing house in Hateno Village (carried over from Breath of the Wild) or complete the "Mattison's Independence" quest chain to unlock customizable housing in Tarrey Town. The Tarrey Town option lets you choose room layouts and exterior aesthetics from preset templates, but you're selecting from Nintendo's designs rather than placing walls and roofs yourself. This is a deliberate design choice. TotK's construction system focuses on vehicles, combat contraptions, and puzzle solutions rather than permanent architecture. The physics engine and Zonai device mechanics are optimized for mobile creations that serve gameplay functions, not static buildings. If you're searching for this because you want player housing with some creative control, the Tarrey Town quest is your best route. You unlock different room configurations (workshop, dining hall, etc.) by spending rupees and materials, then decorate interiors with furniture. It scratches the customization itch without the structural freedom of games like Minecraft or Fortnite Creative. From a game design perspective, this keeps TotK focused on exploration and experimentation with temporary builds rather than settlement management. The construction budget and part limits are tuned for contraptions you'll use for ten minutes, not permanent structures. If Nintendo wanted player-built housing, they would have needed different save systems, part libraries, and likely a dedicated building zone to avoid performance issues across Hyrule's massive map.
