Overview
Wall Decoration Modules are a planned Build Mode feature for inZOI scheduled for the Q4 2026 (October to December) timeframe per the 2026 Roadmap Part 1 letter. The feature will introduce a modular interior and exterior wall decoration system, expanding what players can place on wall surfaces.
As of April 25, 2026, Wall Decoration Modules have not shipped on the live build (v0.7.5). The current Build Mode supports placing individual decorative items (paintings, shelves, mirrors) on walls, but does not yet offer a structured module system that lets players quickly assemble matching wall treatments. The Q4 2026 update will fill this gap.
Confirmed Components
Component | Description |
|---|---|
Interior Wall Modules | Decorative panels, trim, wainscoting, and other module-based interior wall treatments. Specific module types have not been individually disclosed. |
Exterior Wall Modules | Siding, trim, and decorative module-based exterior wall treatments. |
Mix-and-Match System | Modules will be designed to combine flexibly, enabling players to create custom wall treatments rather than using preset all-or-nothing wall styles. |
Connection to Other Q4 2026 Build Mode Updates
Wall Decoration Modules are part of the Q4 2026 building expansion that also includes:
Basements: Underground floor construction.
Wall Decoration Modules: This article.
Terrain Editing: Custom landscape sculpting (initial development).
These three features together substantially expand the customization toolkit. Wall Decoration Modules slot in as the surface-level expansion, while Basements and Terrain Editing expand the structural and environmental dimensions.
Use Cases
Once shipped, the module system will enable:
Detailed Victorian-era wainscoting and crown molding for traditional homes.
Modern minimalist wall accents and trim for contemporary builds.
Cohesive exterior siding patterns (clapboard, shingles, brick) without manual placement of individual decoration items.
Custom patterned walls for themed spaces (tiled bathrooms, painted nursery walls, accent walls).
Existing Wall Decoration Tools
Before Wall Decoration Modules ship, players can already customize walls through:
Standard Build Mode wall paints and materials.
Hanging individual decoration items (paintings, mirrors, shelves) directly on walls.
AI-generated wall textures via AI Texture.
Custom textures uploaded as.png files and applied through the same AI Texture interface.
The Wall Decoration Modules feature is additive: it extends what's possible without replacing the existing tools.
