Multifamily Conversion Floorplate & Plumbing Layout Parser

Adapting office properties to multifamily usage requires rapid evaluation of core-to-window depths and existing plumbing stacks. Construct a computer vision and document parsing tool to analyze floor plan schematics and flag unviable living unit deep space zones. Achieve 90% accuracy in identifying non-compliant windowless dwelling spaces.

What you are building

Build a floor plan parsing pipeline to extract core-to-window distances and evaluate multifamily layout compliance.

How work is evaluated

Evaluation

Evaluates accurate calculation of deep floor space percentage lacking natural light.

Datasets

Public datasets, plus the private datasets you have access to.

How submissions are scored

Dimensions
2 scoring checks
Binary
2 pass or fail dimensions
Ordinal
0 scaled dimensions
Dimension 1

pct_close

Ensures unviable space percentage is calculated accurately.

Binary check

This dimension contributes its full weight only when the submission satisfies the requirement. Partial credit is not awarded.

Dimension 2

area_mae

Mean Absolute Error in dark zone square footage calculation. • target: 50 • range: 0-1000

Binary check

This dimension contributes its full weight only when the submission satisfies the requirement. Partial credit is not awarded.

Learning goals

  • Process commercial floor plan images or vector PDFs to extract outer perimeter and structural core boundaries

  • Calculate maximum distance from habitable space to exterior light source windows

  • Flag residential layout unit designs violating municipal daylight codes (>30 ft depth)

  • Output structured spatial metrics for conversion architects
