Executive Summary
A construction tech platform improved its AI model’s accuracy in interpreting floorplans by annotating underrepresented elements like small interior rooms and outdoor zones. A detailed review and enhancement of ~5,000 plans enabled better recognition of complete residential layouts.
Introduction
Background
AI tools interpreting architectural plans often miss minor but critical features. This project addressed these gaps through improved annotations.
Industry
Construction / PropTech / Architecture / AI Automation
Challenge
Problem Statement
Small indoor spaces (e.g., robes, pantries) and external areas (e.g., decks, patios) were inconsistently labeled, resulting in flawed AI outputs.
Impact
This reduced estimation accuracy, feature detection, and user trust in the tool.
Solution
Overview
The annotation team introduced a new class (“External_areas”) and thoroughly reviewed all previous floorplan labels.
Approach
- Identified missing elements like WIP areas, boxed robes, and bulkheads
- Labeled outdoor areas including decks, alfresco zones, and verandas
- Used visual cues like line thickness to detect hidden rooms
- Applied consistent polygon-based labeling
- Verified results with QA sampling and reference guides
Results
Outcome
Model accuracy improved significantly, especially for small spaces and external areas.
Benefits
- 35%+ improvement in detecting small rooms
- More complete recognition of usable square footage
- Better user confidence and platform adoption
- Foundation for future features like automated BOM generation
Conclusion
Summary
Refined annotations corrected critical blind spots in AI floorplan interpretation.
Future Plans
Add furniture and fixtures, enable 3D rendering, and support compliance checks.
Call to Action
Architectural and construction tech teams should implement detailed annotation strategies to support more intelligent AI floorplan analysis.
