Graph Neural Network–Based Residential Building Layout Design

This is like an AI co-designer that learns from many existing apartment and house floor plans, then suggests new room layouts that follow good design rules—how rooms connect, where corridors go, and overall spatial flow—using graph mathematics instead of just pictures or text.

Executive Brief

Business Problem Solved

Manual residential layout design is slow, iterative, and highly dependent on expert architects to ensure functional adjacency (e.g., kitchens near dining rooms, bathrooms near bedrooms) and regulatory constraints. This approach uses a graph neural network to automatically learn patterns from many existing floor plans and propose new, valid layouts, reducing design time and improving consistency.

Value Drivers

Design time reduction for floor plans and variantsLower architectural labor cost on repetitive layout tasksMore consistent adherence to adjacency and circulation rulesFaster exploration of many alternative layouts for a given footprintPotential improvement in space utilization and functional quality

Strategic Moat

Potential moat comes from a large, curated corpus of labeled residential layouts encoded as graphs, plus any proprietary encoding scheme that maps architectural constraints into a graph structure suitable for GNN learning.

Differentiation Factor

Instead of rule-based or purely image-based generative design, this work models a layout as a graph of rooms and connections and uses a graph neural network to learn spatial/functional relationships directly from existing buildings, enabling structure-aware generation and evaluation of layouts.
