What is TestFit
TestFit is a real estate feasibility and site-planning application that generates and evaluates building and parking layouts against zoning and site constraints. It is used by developers, architects, and planners during early-stage due diligence to test massing, unit counts, parking ratios, and basic financial assumptions. The product emphasizes rapid scenario iteration and constraint-based layout generation rather than detailed construction documentation.
Fast early-stage scenario testing
TestFit supports rapid iteration of site plans and building massing to compare multiple development options early in the process. This can reduce manual redraw cycles typical of general-purpose CAD tools during feasibility studies. It is well-suited to quick “what fits” analyses before committing to a detailed BIM model.
Constraint-driven layout generation
The software uses inputs such as site boundaries, setbacks, parking requirements, and program targets to generate candidate layouts. This approach helps teams explore options while keeping key constraints visible and consistent. It is particularly useful for multifamily and parking-heavy site configurations where rule checking is repetitive.
Feasibility metrics alongside geometry
TestFit pairs geometric outputs with feasibility-oriented metrics such as unit counts, parking counts, and area summaries. This helps align design exploration with development assumptions during underwriting and concept validation. It can serve as a bridge between planning discussions and later BIM/CAD detailing.
Not a full BIM authoring tool
TestFit focuses on early planning and massing rather than detailed BIM elements, documentation, and downstream construction deliverables. Teams typically still need dedicated BIM/CAD software for detailed modeling, coordination, and drawing production. As a result, it is not a single-system replacement for end-to-end design workflows.
Workflow depends on integrations
Moving from feasibility studies to detailed design often requires exporting and reworking geometry in other tools. The quality and fidelity of handoff can vary by format and target application, and some re-modeling may be required. This can introduce coordination overhead compared with staying within one primary authoring environment.
Best fit for specific typologies
The strongest use cases tend to be common real estate typologies (for example, multifamily with structured or surface parking) and zoning-driven site planning. Projects with highly bespoke geometry, unusual programs, or complex engineering constraints may see less benefit from automated layout generation. In those cases, manual CAD/BIM modeling may remain the primary approach.
