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.
Site context
Brooklyn corridor multifamily
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.

FAR, envelope and program
The engine's interpretation of the lot's zoning rules, applied to produce the buildable envelope, height, and per-floor program.

The envelope, rule by rule.
Every constraint the engine applied to C6-3A, with the Zoning Resolution section that imposed it. The full report carries the complete citation table and a rule browser that explains each number from its inputs.
Envelope · C6-3A
Form: Standard Housing. Contextual district: ZR 23-731 confines the optional sky exposure plane regime to R6-R10 Districts without a letter suffix, so the ZR 23-432 standard height and setback envelope is the only residential form.
What the Code requires for this building.
Chapter 5 and its neighbours, applied to the Maximum Area Scenario scenario: construction type, egress, elevators, sprinklers, accessibility. This is the part an architect checks first.

City of Yes and the tax programs, checked.
Which bonus programs the lot qualifies for and what each one is worth here, and which tax incentives a project on it could claim. The report models the qualifying scenarios as buildings, not footnotes.
