Home Builder 5 is a parametric design plugin for Blender that automates the generation of interior walls, cabinetry, and furniture. This software extension provides a comprehensive toolset for interior space planning directly within the Blender environment. It focuses on the parametric generation of architectural elements, allowing users to define and adjust wall configurations, kitchen cabinet layouts, and various furniture pieces through a unified interface. By abstracting complex modelling tasks into adjustable parameters, the plugin facilitates rapid iteration of interior layouts. It is designed to handle the specific geometric requirements of architectural interior design, ensuring that components maintain structural logic while providing the flexibility needed for custom space planning and detailed room composition.

Users install this plugin via the standard Blender addon manager, which then integrates a dedicated panel into the interface. Once active, designers can drag and drop parametric components into the 3D viewport, adjusting dimensions and attributes through the sidebar properties. The workflow relies on real-time updates, where modifying a parameter instantly propagates changes across the selected model, streamlining the transition from initial space planning to detailed interior modelling within the native environment.

Ideal for residential and commercial interior design projects, this tool excels in the early stages of space planning and layout development. It is particularly effective for kitchen design, office interior fit-outs, and custom cabinetry modelling where frequent adjustments are required. By leveraging parametric controls, professionals can quickly generate multiple design options for client presentations. It pairs well with standard architectural workflows, allowing for efficient transition from conceptual layouts to final high-fidelity visualisations, ensuring consistency across complex interior design schemes.
