01Built form

Massing and elevation

The top scenario's massing, drawn from the engine's per-floor plates: an axonometric of the volume and a side elevation with story heights and use mix. Where the ground floor reads wider than the floors above, that is the computed setback envelope, not a stylization. The full report adds cross-sections at the critical heights and the sky-exposure plane.

02Floor synthesis

Synthesized floor plans

Per-floor plans drawn by the engine from the buildable envelope: cores sized to code, corridors, apartments with rooms and fixtures, and the roof with its bulkheads. Diagrammatic, for feasibility; not for construction. The PDF carries every floor of every scenario with a unit schedule under each plan.

Form: Quality Housing. District permits both forms. Quality Housing recommended: it is the practical pathway for new construction post-2018 / under City of Yes and typically yields a fuller envelope than the sky-exposure-plane Height Factor form on lots <100 ft deep.
