Arosa

Arosa helps New York build more housing. The city's housing affordability crisis is why we are building it: homeowners, small builders and developers need a clearer way to understand what each lot could become. Start with a New York address and a housing goal. Inspect zoning and property sources, compare building options, test the economics, and turn an explicitly assumed or imported plan into editable artifacts and a browser walkthrough. The demo follows 23-29 Broadway in Astoria: could one more home fit while keeping the existing building? Modeling and Underwriting work independently. Saved plan revisions connect the plan, IFC, Pascal scene, Blender file and browser model. Supported IFC identities, dimensions and placements are preserved, with import losses reported. Scan checks report alignment, face distances, tolerance and sampling. Photo-based illustrations remain separate from measured geometry. Hackathon additions include Meta-powered independent research workflows, durable review and reconnect behavior, improved plan provenance, consistent handoff artifacts, refined walkthrough presentation, SAM/Muse Image illustrations and a bounded Muse Wonder Full edit. Earlier property, Underwriting and rendering foundations are identified in the film and contribution record. Results support preliminary exploration, not a survey, permit or professional zoning determination. Our goal is clearer housing options for New York builders, architects and communities.
