Real estate feasibility platform for testing sites: automated site plans, parking layouts, deal evaluation and concept iteration, with exports to Revit, AutoCAD, SketchUp and Excel.

Overview

TestFit is a real estate feasibility platform for testing what can be built on a site. Users map a parcel or draw a custom boundary, set road layouts, topography and zoning parameters, and generate an editable site plan with 3D massing that is tied to deal financials.

The product is split into Site Solver, which generates building and site options across typologies such as multifamily, mixed-use and industrial, and Parking Solver, which lays out surface and structured parking. Add-ons include Site Intelligence for zoning, environmental and terrain data, Pro Forma for financials linked to the design, and an MCP Connection for working through an AI assistant.

Saved schemes can be compared on metrics such as yield on cost and efficiency, and the platform produces takeoffs for parking, earthwork and building area. TestFit lists a Revit add-in and exports to formats including DXF, SketchUp, glTF, CSV and PDF, and its homepage also names AutoCAD and Excel.

Main capabilities

  • Generative site plans from zoning and code parameters
  • Surface and structured parking layout generation
  • Cut-and-fill and earthwork cost estimates
  • Pro forma financials synced to the site plan
  • Side-by-side scheme comparison and deal pipeline
  • Revit add-in and CAD, SketchUp, Excel exports

Who it's for

TestFit markets the platform to developers, architects, contractors, civil engineers, urban and city planners, brokers, brands, universities and municipalities. Its typology pages cover multifamily, single-family, industrial, data center, retail, hotel and parking projects, and the tool is positioned for early-stage feasibility and deal evaluation before detailed design.

The AI angle

TestFit describes Site Solver as a generative design tool: users set code parameters, goals and constraints such as FAR, parking ratio, height and unit mix, and the software produces many design options in seconds. Users can pick a preferred option and regenerate similar ones with adjusted goals, according to the company.

The MCP Connection add-on lets users drive TestFit from an AI assistant they already use; the company names Claude and ChatGPT. Plain-language prompts go to the assistant, and TestFit's engine returns site plans, geometry and numbers as an editable model that can also be changed by hand. TestFit says the design work is done by its deterministic engine and that it does not supply, embed or train an AI model.
