Initial building guide with home design, houseboats, terrain modification, and waterpark features
The building system in Starsand Island has drawn comparisons to The Sims, and that comparison is earned. You do not just place furniture in a pre-built house. You can redesign walls, change the size and shape of rooms, swap roofs and windows, modify terrain, and build on three different property types.
You can own and customize three distinct spaces:
Homestead -- Your main house and farm on the island. This is where you start.
Houseboat -- A boat you can live on. The developers call it a "flagship feature." It unlocks through the main quest line.
Private island -- An offshore island you can eventually own and develop.
The DIY building mode gives you full control over structure:
Move, add, and remove walls
Change room sizes and shapes
Swap windows, doors, and roofing
Customize colors and designs on nearly every surface
Place objects anywhere within your property zone
Build block-by-block or use prefab buildings that require specific materials
There are over 300 furniture pieces and hundreds of decorative items. Serena's furniture shop is the main source, though you can also craft items yourself.
Beyond buildings, you can reshape the land itself:
Create hills and elevated areas
Dig waterways and moats
Build cascading terrace gardens
Add ivy and flora decorations to structures
This means your farm does not have to be flat fields. You can create a terraced hillside farm with a moat around your house if you want.
One of the more unexpected features: you can build water slides and waterpark attractions on your property. Once built, you ride them in first person. Preview coverage compared this to Planet Coaster 2's ride-building. It is a side activity, not a core progression system, but it is there.
Over 300 furniture pieces are available. Sources include Serena's furniture shop, crafting, exploration rewards, and seasonal events. You can place items freely within your property zones, rotate them, and customize colors where applicable.
A creation-sharing system via ID codes is planned for the full release. This would let you share home designs with other players. Multiplayer co-building is also planned.
