TestFit

TestFit is the site feasibility solver that generates buildable schemes — parking, units, units per acre, cost — while the deal is still live.

Overview

TestFit addresses the speed problem in real estate feasibility. Enter a site, set the program and constraints, and its solver instantly produces coordinated building configurations with parking layouts, unit mixes, efficiency ratios and rough costs. Dozens of scenarios can be tested in the time a manual test fit once took days.

The tool is designed around the realities of deal-making: configurations respond to zoning setbacks, height limits, parking ratios and structure grids, and results can be exported to CAD and BIM for the design team that wins the work. Architects use it to win and scope work; developers use it to decide whether a deal pencils.

Deals move on deadlines measured in days, and TestFit is built for that tempo. A development team can test whether adding a level of parking or shifting the building footprint changes the yield enough to justify the land price, all while the acquisition is still under negotiation. Architects use the same solver to arrive at client meetings with credible schemes rather than sketches, and to price their own involvement with real information. The solver handles the tedious geometry of parking structure layout and unit stacking particularly well, tasks that consume days of manual test fitting. When a deal proceeds, exports hand the geometry to design teams without throwing the work away, so feasibility effort compounds instead of restarting.

In the architecture and building design category, the deciding factor is usually interoperability: AI-driven design tools earn their place when their output flows into the BIM and documentation workflows firms already run, rather than becoming an isolated experiment that must be redrawn by hand.

Key Features

• Real-time solver for building massing, unit mix and parking
• Constraint handling for zoning, setbacks, height and parking ratios
• Instant yield metrics: efficiency, units per acre and rough cost
• Scenario comparison for fast deal decision-making
• Export to CAD and BIM for downstream design
• Support for multifamily, mixed-use, hotel and industrial typologies

Pricing

TestFit is sold through annual site-licensed subscriptions; pricing is quote-based and scales with seats and typology modules.

Who Is It For

Real estate developers, architects doing feasibility and test fits, and acquisitions teams who need to know within hours whether a site works.

FAQ

Is TestFit free to use?

No — TestFit is an enterprise product, though the team runs guided evaluations so you can test it against a live deal.

Does TestFit offer an API?

Integrations focus on CAD/BIM export and data exchange; bespoke automation is discussed with enterprise customers.

How does TestFit compare to alternatives?

TestFit goes deeper on parking, deal metrics and typology-specific rules than generic generative design tools, but it is a feasibility solver, not a full design authoring environment.
