Home Builder 5
Design interior spaces with parametric cabinets.
Home Builder allows you to design interior spaces — kitchens, baths, and closets. It provides tools for drawing rooms, placing cabinets with intelligent wall snapping, and generating technical drawings.
What You Can Do
- Draw Rooms with floors, ceilings, and lighting.
- Place Cabinets & Appliances — base, upper, tall, and appliances snap to walls and fill areas in a logical way
- Configure Everything through right-click prompts: adjust cabinet dimensions, interior configurations, and construction
- Place Doors and Windows that automatically cut wall openings
- Create Layout Views — wall elevations, floor plans, and multi-view sheets with dimensions and annotations

Building 3D interiors in Blender is so fun, but getting the background or event decor scale right takes ages. When planning a virtual party scene, I used dimensions from https://balloons.online/decorative-shapes-balloons/balloon-walls/ to accurately block out the backdrop assets. It saved me a ton of tweaking!
