Test Fit Analysis

Test fit analysis is the process of determining whether and how a proposed building program can physically fit on a development site within zoning and regulatory constraints. It includes massing studies, floor plate layouts, parking configurations, unit mix optimization, and preliminary site planning. AI tools can now generate and evaluate multiple test fit scenarios rapidly, accelerating early-stage development feasibility.

What test fits evaluate

A test fit analysis examines: building footprint and massing within zoning envelopes, floor plate efficiency and layout options, parking requirements and configuration (structured, surface, underground), unit mix and size optimization (for residential), tenant layout options (for office and industrial), site circulation, loading, and access, open space and amenity requirements, and code compliance (fire access, egress, ADA).

AI-powered test fits

Traditional test fits require architects to manually draft and iterate on layouts — a process that takes days per scenario. AI-powered test fit tools can generate dozens of compliant scenarios in minutes, optimize for different objectives (maximize units, maximize rentable area, minimize construction cost), and quickly identify the development program that maximizes financial returns within physical constraints.
