Floor Plan Datasets for Spatial AI and Real Estate Technology
Annotated floor plan datasets with room segmentation, space type labels, and metric dimension estimates. Built for floor plan parsing, spatial AI, and real estate technology applications.

The Challenge
Beyond Public Floor Plan Benchmarks
CubiCasa5K and Rent3D established floor plan parsing benchmarks. Production spatial AI for real estate search, facility management, and interior design requires floor plan coverage matched to your property types and annotation depth.
Real estate platforms need floor plan parsing across diverse property types, drawing styles, and scan quality levels found in listing submissions. Facility management AI needs metric space estimation and room type classification for commercial floor plan archives with non-standard drawing conventions.
Off-the-shelf floor plan datasets suffer from property type gaps (residential-only coverage misses commercial, industrial, and institutional floor plans) and scan quality gaps between clean benchmark drawings and real-world listing scans.
LXT builds custom floor plan datasets covering your property types, drawing styles, and annotation schema. We deliver room segmentation, space type labels, and metric estimates that train spatial AI systems for your specific real estate or facility management application.
Why Teams Upgrade
Limitations of Public Floor Plan AI Datasets
Standard benchmarks serve research well. Production deployments need more.
| Dataset | Primary Limitation | Impact |
|---|---|---|
| CubiCasa5K | 5,000 Finnish residential floor plans only; specific drawing style; no commercial, industrial, or non-European property types | Finnish residential |
| Rent3D | Apartment listings only; limited to residential; no commercial building or institutional floor plan coverage | Apartments-only |
| LIFULL HOME'S | Japanese residential market only; specific drawing conventions; no Western, commercial, or custom property types | Japanese market |
| R2V | Raster-to-vector conversion focus; limited annotation depth; no room semantic labels or metric dimension annotation | Vectorization-only |
| Structured3D | Synthetic 3D scenes only; no real floor plan drawings; sim-to-real gap limits production applicability | Synthetic only |

We've built datasets across dozens of domains and use cases. Let's scope yours.
Capturing Complexity
Edge Cases in Floor Plan Parsing
High-accuracy models handle rare attributes that public datasets miss.
Non-Standard Drawing Conventions
Older and international floor plans use non-standard symbols, abbreviations, and drawing conventions. Annotation guidelines document regional and era-specific convention handling.
Poor Scan Quality and Degradation
Real estate listing scans include folds, low contrast, and rotation. Realistic scan quality distribution in training data prevents failure on low-quality listing submissions.
Open Plan and Ambiguous Room Boundaries
Modern open-plan layouts have ambiguous room boundaries. Annotation guidelines define how to handle open-plan partitioning for consistent model training.
Multi-Floor and Complex Layouts
Multi-story buildings require understanding of stairwell, elevator, and floor connection elements. Multi-floor relationship annotation supports building-level spatial understanding models.
Ground Truth Quality
Human-in-the-Loop Annotation
Precise annotation bridges raw data and learnable signal. Expert annotators deliver precision automated tools can't match.
Room Segmentation
Expert annotators draw polygon boundaries for each room and space with room type labels from your classification taxonomy. Boundary precision guidelines applied per plan quality tier.
Metric Estimation Labels
Room area and principal dimension estimates by scale calibration or reference measurement for spatial size estimation model training.
Space Type Classification
Custom space type taxonomy annotation including room function, occupancy type, and building element labels aligned to your application schema.
