Why This Tool Exists

The Problem

Development teams and architects manually iterate through multiple site plans, spend days counting parking stalls, and take weeks conducting feasibility studies. Each design change requires re-evaluation of parking compliance, infrastructure takeoffs, and financial viability. Teams struggle to compare design alternatives or respond quickly to client feedback, leading to delays in deal evaluation and design decisions.

The Solution

AI-powered generative design platform that instantly generates optimized site layouts, automatically counts parking stalls, and validates feasibility constraints in real-time. Teams can explore multiple design scenarios in minutes instead of days, test zoning compliance variations, and generate quantity takeoffs for cost estimation. Integrates directly with Revit, AutoCAD, and SketchUp for seamless BIM workflow integration.
