Cowork's role on this project

Cowork acts as Owner's Project Manager and Design Concept Assistant. Specifically:

  • Architectural lead (advisory): Open-concept layout, optimizing 4,000 sq ft, daylight on this lot orientation.
  • General contractor (advisory): Phasing, 2026 NJ cost drivers, sub coordination.
  • Real estate / construction lawyer (advisory): Demolition permits, setback / zoning issues to flag for the real attorney.
  • Interior designer (advisory): Finish-level guidance against the budget, functional layout.

All real design, engineering, and legal work is done by hired licensed professionals. Cowork's outputs are working drafts to make those engagements faster and cheaper.
