Building Architect is a modular building generator for Unity that creates complete Buildings structures.Building Architect is a fully modular exterior building generator designed for artists, level designers, and technical creators who want fast, flexible, and reliable procedural architecture inside Unity.With a clean and intuitive workflow, you can generate complete buildings — including walls, floors, facades, sloped roofs, flat roofs, and roof props in a simple click. Every change updates instantly in the editor, making iteration fast and enjoyable.The system is built around a robust modular architecture: each building is assembled from interchangeable prefabs, allowing you to plug in your own assets, materials, and styles. Whether you're creating realistic cities, stylized environments, or prototype layouts, Building Architect adapts to your pipeline.Key Featuresprocedural generation Buildings Generate instantly floors, roof types, or design settings in 1 clic.Modular prefab‑based architecture Plug in your own wall modules, windows, doors, roof tiles, and props.Complete roof systemSloped roofs with multi‑row logicFlat roofs with edge and center modulesFully functional roof prop placement for both modesFacade generation Automatic placement of windows, doors, shops, and decorative elements with symmetry options.Captured facade plans Lock and reuse facade layouts across floors or entire buildings.Artist‑friendly controls Width, length, floors, symmetry, roof mode, and design presets — all editable in realtime.Clean hierarchy & optimized structure Generated buildings are organized, readable, and ready for further editing or export.Use CasesOpen‑world citiesStylized towns and villagesPrototyping and level blockoutsArchitectural visualizationProcedural content toolsGame‑ready modular environmentsBuilding Architect gives you the speed of procedural generation with the control of handcrafted assets — a perfect balance for modern Unity workflowsPerformance‑ready architecture: Generated buildings follow a clean, modular hierarchy that works seamlessly with Unity’s occlusion culling, frustum culling, and LOD systems. Whether you use Unity’s built‑in tools or a custom optimization pipeline, Building Architect integrates smoothly into performance‑critical environments such as open‑world cities or large‑scale levels.RequirementsUnity 2021.3+ (recommended)Works in URP, HDRP, and Built‑inEditor‑only generation (runtime generation optional with minor adjustments)IncludedFull building generator systemFlat roof generatorSloped roof generatorFacade and floor generation systemRoof prop system (Flat + Sloped)Sample modular assets (for demonstration)Complete C# source codeEditor tools and custom inspectorsFeaturesProcedural building assemblyModular prefab‑driven designRealtime editor updatesCaptured facade plansRoof prop placement with spacing, probability, and socket rulesSymmetry options for facadesClean, documented codebaseExtensible architecture for custom modulesPerformanceLightweight and optimizedNo heavy runtime overheadDesigned for large‑scale city generation workflowsPipeline CompatibilityWorks with any modeling style (realistic, stylized, low‑poly, voxel, etc.)Compatible with custom materials, shaders, and lighting setupsSupports nested prefabs and variant workflowsOptimized for real production environments: Building Architect is structured to work flawlessly with camera occlusion, frustum culling, and LOD systems. Each generated building is organized into predictable, modular groups, making it easy to attach LOD Groups, apply custom culling rules, or integrate third‑party optimization tools.
