Transcript-sourced update: seamless indoor/outdoor (no loading screens), grid alignment + perspective mode precision tools, weather/time/lighting preview for perfectionists, decorative items by style category, 8 named presets, terrain editing specifics for Windflute Island, beginner guide
The building system in Starsand Island has drawn comparisons to The Sims. You do not just place furniture in a pre-built house. You redesign walls, change room sizes, swap roofs and windows, modify terrain, and build across multiple property types. Seed Sparkle Lab built a custom engine from scratch to support this system.
House interiors and exteriors are designed as a fully integrated system. You move seamlessly between indoor and outdoor spaces with no loading screens. Walk from your front yard into your living room without any transition.
The building system can feel overwhelming. The developers have introduced a beginner-friendly building guide for anyone who feels intimidated by the full build mode. If you want to skip the learning curve entirely, there are eight preset home layouts you can build with a single click once you have the materials.
The building system includes precision tools for detailed work:
Grid alignment -- Snap items to a grid for clean, even placement.
Perspective mode -- Check how things look from your character's eye level.
Foundation laying -- Set down building foundations before adding walls.
Item rotation -- Freely rotate any placed object.
Eight pre-designed home layouts are available. Gather the materials and build your dream home with one click. The presets are well-designed and go beyond basic templates:
Chinese Courtyard -- Traditional courtyard design with cultural details.
European Villa -- Classic European architecture.
Luxury Amusement Park -- Includes actual rides and attractions. A full amusement park on your property.
Houseboat -- A floating home on the water.
Advanced Modern Retreat -- Sleek, contemporary design.
Three additional preset layouts with different themes.
You can start with a preset and customize it from there, or build entirely from scratch. The presets are designed to be inspiring starting points, not limitations.
For perfectionists, build mode lets you preview your home in different weather conditions (rain, snow), times of day, and lighting setups. This is useful for testing how your property looks at night, how outdoor lighting works, and whether your landscaping holds up in winter snow.
Free-view -- Overhead camera for planning layouts and placing structures.
Character perspective -- Third-person view from your character's position. Check sightlines and how rooms feel at ground level.
Local view -- Close-up view for fine-tuning individual items and decorations.
You can own up to nine homestead subplots across three environments:
Blue Beach -- Coastal plots with ocean views and beach access.
Cloudrest Lake (Bamboo Forest) -- Lakeside plots surrounded by bamboo groves and rolling hills.
Windflute Island (Private Island) -- Elevated island plots with open sky and wind. This is where full terrain editing is available.
Nine subplots need to be unlocked through gameplay to expand your homestead.
A boat you can live on. The developers call it a flagship feature. You customize it the same way as a house: walls, floors, furniture. You can even farm on it using planter boxes.
The DIY building mode gives you full control:
Lay foundations, rotate items, use grid alignment and perspective mode for precision
Move, add, and remove walls
Change room sizes and shapes
Swap windows, doors, and roofing
Eight texture types: wood grain, brick, stone, plaster, metal, tile, concrete, and glass
Customize walls and floors with different materials independently
Decorate your space with almost anything you find in the game, from snacks to old tools
Build block-by-block or use prefab buildings
There are nearly 1,000 decorative items available across multiple style categories:
Classic -- Timeless, traditional designs.
Modern -- Contemporary, clean-lined furniture.
European -- Ornate, continental-style pieces.
Traditional -- Chinese and Asian-inspired decor.
Whimsical fairy tale -- Fantasy-themed decorations.
Serena's furniture shop is the main source. You can also craft items, earn them from seasonal events, or turn giant crops into seasonal furniture.
On Windflute Island (your private island), you have full terrain control. The limits are nearly endless:
Shape hills and elevated areas
Dig lakes and water features
Lay roads
Design gardens however you like
Build cascading terrace gardens
Add ivy and flora decorations to structures
A Kickstarter base goal feature. Build water slides and waterpark attractions on your property. The Luxury Amusement Park preset layout includes actual rides and attractions, including what appears to be a ferris wheel and roller coaster-style elements.
A Kickstarter $250K stretch goal. Save your building designs and share them with other players via ID codes. Download someone else's house layout and build it on your own property.
The Camera App on your phone lets you take photos that can be framed and hung on walls as decorations.
