TestFit

TestFit is a real estate feasibility and generative design platform that helps property developers, architects, civil engineers, contractors, urban planners, and other construction professionals evaluate land and explore building possibilities before committing to detailed architectural design. The software is designed to make early-stage development decisions faster by combining site planning, building configuration, parking layouts, zoning considerations, cost analysis, and design automation in one workflow.

The platform addresses a common challenge in property development: determining whether a particular site can support a proposed project and whether the project is financially and physically viable. Traditionally, this process can involve manually reviewing site boundaries, zoning rules, building dimensions, parking requirements, circulation, unit layouts, and other development constraints. These activities may require repeated calculations and several rounds of preliminary drawings. TestFit automates many of these tasks, allowing users to generate and compare development scenarios much more quickly.

One of TestFit’s central capabilities is automated site planning. Users can select a parcel, import or draw a site boundary, and configure the requirements for a proposed development. The platform can then generate layouts based on parameters such as building dimensions, unit mix, parking ratios, road access, circulation, and other project requirements. Users can adjust the generated design rather than having to accept a fixed result. This makes it possible to explore several potential arrangements and compare how each option uses the available land.

TestFit supports several development types, including multifamily residential buildings, single-family housing, industrial facilities, retail developments, hotels, parking structures, and data centres. This range makes it useful for different types of real estate feasibility studies. A residential developer, for example, can examine how many units may fit on a parcel, while an industrial developer can explore building placement, access, circulation, and site utilisation. For data centre projects, users can assess facility configurations and related site requirements.

The software also includes tools for building configuration and massing. Users can create conceptual building layouts, adjust building dimensions, examine floor plates, and review how a proposed structure fits within its site. The platform can generate two-dimensional plans and three-dimensional visualisations, helping teams understand the relationship between buildings, parking areas, access routes, and surrounding site conditions. These visual outputs can support early design discussions and help stakeholders understand a proposed development before more detailed modelling begins.

Parking automation is another important part of TestFit. The platform can generate parking arrangements and calculate parking capacity according to project requirements. Users can work with parking stalls, drive aisles, circulation routes, and other layout elements. This is particularly useful for developments where parking requirements have a major influence on the number of units or the amount of usable building space. Users can modify generated arrangements to explore different parking strategies and evaluate how those changes affect the overall site plan.

TestFit also provides tools for analysing site constraints and environmental conditions. Depending on the selected subscription and available data coverage, users can access site intelligence features that provide information about zoning, environmental constraints, terrain, flood zones, wetlands, soil conditions, and other relevant site characteristics. Terrain analysis can support grading studies and cut-and-fill calculations, helping civil engineers and development teams understand how the natural shape of a site may affect construction requirements. Data availability varies by location, so users should confirm that the relevant information layers are supported in their project area.

Generative design is one of the platform’s major capabilities. Instead of relying entirely on manual adjustments, users can define project requirements and allow TestFit to explore different design possibilities. The system can evaluate parameters such as building configurations, unit mixes, parking arrangements, and other development conditions to identify alternative solutions. Users remain able to review, edit, and refine the results. This approach helps teams investigate more options during early feasibility work while maintaining control over the design direction.

The platform also connects design decisions with financial evaluation. Its pro forma functionality can link a proposed layout with financial assumptions, allowing users to understand how changes to a design may affect a project’s financial performance. Users can work with their own Excel templates and evaluate development scenarios using information from the proposed layout. This is valuable because a site may appear physically suitable but still fail to meet the financial requirements of a project. By connecting design and financial analysis, TestFit helps teams consider both questions earlier in the development process.

Quantity takeoff and cost-related tools provide additional support for early project evaluation. TestFit can generate quantities associated with elements such as parking, infrastructure, and earthwork. These outputs help teams develop preliminary cost assessments and compare the implications of different site arrangements. They are intended to support feasibility and early decision-making rather than replace detailed construction estimates or professional engineering assessments.

TestFit also supports collaboration and the preparation of project information for other stakeholders. Users can create feasibility reports, compare design scenarios, share project information, and communicate the results of site studies. These capabilities help developers, architects, contractors, and consultants discuss the same project using a common set of layouts and data. Reports can bring together site information, design visuals, and comparisons between different development options.

Integration with other professional software is an important part of the TestFit workflow. The platform supports connections with Autodesk Revit and exports to tools such as AutoCAD and SketchUp. These connections allow teams to move conceptual layouts into later design and documentation stages. TestFit also supports exports in formats such as CSV, DXF, glTF, PDF, and SKP, making it easier to transfer project information to other applications and share it with consultants.

The platform’s MCP connection provides another way to interact with TestFit. It allows compatible AI assistants to connect to the software and prompt editable site plans through natural-language instructions. This can help users explore project options without relying exclusively on manual interface operations. The MCP connection is offered as an optional paid add-on for the Parking Solver subscription and is included with the Site Solver plan.

TestFit is primarily intended for professional real estate and built-environment workflows rather than general-purpose image generation or casual home design. Its main value is in helping teams evaluate development opportunities, understand site constraints, compare building layouts, and make informed decisions before moving into detailed design. It can be particularly useful during land acquisition, preconstruction planning, feasibility assessment, concept development, and early project costing.

Overall, TestFit brings together automated site planning, generative design, building configuration, parking analysis, site intelligence, and financial evaluation. By reducing the time required to create and compare preliminary development scenarios, it helps property and construction professionals investigate opportunities more efficiently and communicate their findings more clearly.

Review

TestFit is a specialised platform for professionals who need to evaluate land, generate development layouts, and compare real estate project scenarios. Its strongest advantage is the way it brings site planning and feasibility analysis together. Rather than treating preliminary design as a separate activity from project evaluation, the platform connects building layouts with parking, site constraints, quantities, and financial considerations.

The automated planning and generative design capabilities can help users explore multiple options in less time than a fully manual workflow. Its support for different building types also makes it relevant to a wide range of development projects. Integrations with Revit, AutoCAD, and SketchUp are useful for teams that need to transfer early concepts into established design and documentation tools.

However, TestFit is a specialised professional product, and its subscription prices may be difficult for individuals, students, or small teams to justify. Some advanced capabilities require higher-tier subscriptions or paid add-ons. The platform also has a learning curve because users need to understand site planning concepts, development parameters, and the assumptions behind feasibility results. Its data layers are not equally available in every country, which may limit some site intelligence features for international projects.

TestFit is best suited to property developers, architecture firms, civil engineering teams, contractors, and urban planning professionals who regularly assess development sites. It is less suitable for users looking for a simple room-design application or a general-purpose visual design tool. For its intended professional audience, it offers a focused set of tools that can improve the speed and organisation of early-stage real estate decisions.
