Overview
Build Mode is the construction and decoration system in Starsand Island. It lets you design and customize your home, homestead, and any unlocked property on the island, from the walls and roofs of your house down to individual furniture placement, fish-tank arrangement, and exterior landscaping. Build Mode is the primary gameplay loop for the decoration side of the game and is deeply tied to the Blueprint Library for save-and-share designs and to the Land Expansion system for enlarging the footprint you can build on.
Three Construction Perspectives
Build Mode offers three different camera perspectives, each optimized for a different kind of placement task. You can swap between them freely while Build Mode is open.
Perspective | Best For |
|---|---|
Free-View | Bird's-eye perspective for placing exterior structures, fences, paths, gardens, and large outdoor decorations. Rotate and pan the camera freely across the plot. |
Character Perspective | First/third-person view for arranging indoor furniture, wall-mounted items, and room-to-room decoration. Uses the same camera as regular gameplay so you see the space as your character sees it. |
Local View | Close-up mode for detailed placement in small spaces such as fish tanks, planters, shelves, and display cases. Fine placement precision inside a bounded area. |
Features
Nearly 1,000 placeable items across furniture, decorations, structures, functional stations, and outdoor props.
Eight paint textures for walls and structural surfaces: wood grain, brick, stone, gloss paint, matte paint, metallic paint, micro cement, and ceramics.
Full Blueprint Library integration for saving entire builds (or individual rooms) to share with other players and reload later.
Eight pre-designed layouts for players who want a ready-made look, including a Floating Oasis houseboat design.
Property expansion via the Land Expansion system, unlocking additional land tiles in Hopeland, Cloudrest Lake, Blue Beach, and Windflute Island.
Undo history for the last five placement actions so misplaced items are easy to roll back without leaving Build Mode.
Multi-select for bulk moving, rotating, or deleting groups of placed items in one motion.
How to Access Build Mode
Build Mode is available from the start of the game for your initial home. The system unlocks its full feature set after you complete the early Island Life progression steps with Solara, which introduce you to building, decoration, and the Self-Service Terminal. Press the designated Build Mode key on your platform (check Controls and Keybindings for the current binding) to enter or exit Build Mode. Most players remap this to a convenient key on PC or a dedicated face button on Xbox controllers.
Build Mode can be accessed anywhere on unlocked property. The available item list is limited to what you have purchased from
You can purchase furniture and decorations from Lex Woodworks (Serena's shop in Starsand Town) or craft most pieces at your Worktable. Some items are also sold at the Starsand Shop in the Community Center, at Zerine's General Store, and at specialty vendors.
Blueprint Library
Every build you make in Build Mode can be saved to the Blueprint Library as a reusable template. Blueprints capture the full geometry of a structure plus every placed decoration inside it. Two use-cases drive most Blueprint Library activity:
Saving your current home before remodeling, so you can roll back to an earlier design if a new layout does not work out.
Sharing designs with the community or pulling down other players' builds by exporting and importing blueprint files. This becomes the foundation of the Island Visiting feature planned for the June 2026 multiplayer update on the Post-Launch Roadmap.
Tips
Save a blueprint of your house before any major remodel. Blueprint rollbacks are far cheaper than rebuilding from scratch.
Place a bed outside your house or inside a shed on your property. You can sleep in any bed you own, and an outdoor bed skips the house-loading screen compared to the indoor bed.
Purchase furniture from Lex Woodworks (Serena's shop) for styled pieces that are hard to craft, and craft structural elements like walls, roofs, and basic furniture at your Worktable.
Use the multi-select tool when moving or deleting large groups of items. It is much faster than picking each piece up individually and prevents accidental misclicks on nearby decor.
When using Local View inside a fish tank or planter, zoom fully in before placing small items. The placement preview is more accurate when the camera is close to the target.
If the build bar opens empty ("No items in current category"), this was a known bug fixed in patch 0.4.8191. Update to the latest build on your platform.
