Parametric Massing Generator

Generates a buildable massing envelope from zoning constraints, on a rectangular or an irregular parcel, with AI-assisted parsing, source citations, and an independent reviewer pass.

Generation history (traceable record)
Nothing generated yet this session.
Buildable envelope only, a first-pass generative check before detailed design. Height/construction-type and daylighting notes are simplified rules of thumb, not code-compliance advice. Built with Three.js.
