Testfit
TestFit generates editable site plans, parking layouts, and 3D massing from a parcel, unit program, and your zoning constraints.
Buy TestFit when feasibility studies are a weekly habit, not a one-off. The $195/month Parking Solver floor is honest for parking and massing work; generative design, custom unit types, and a dedicated account manager sit behind the $15,000/year Site Solver gate. Customers report going from 2–3 jobs a week to 100 jobs versus 400+ a year after switching — that math only works at volume.

Skip TestFit if you run fewer than a handful of site studies a year — with no pay-as-you-go option and generative design gated to the $15,000/year billed annually Site Solver tier, a one-off project won't earn back the subscription.
Generative design, high-detail building presets, and custom unit types are gated to Site Solver at $15,000/year billed annually, so the $195/mo Parking Solver plan won't cover the automated exploration most teams are
Parking Solver at $195/mo billed monthly is priced against hiring a preconstruction analyst for a single study and is far cheaper than dedicated parking-design software plus a massing tool. Site Solver at $15,000/year billed annually is priced for a firm with a steady feasibility pipeline, and lands below a single new architecture hire. Portfolio at $20,000/year billed annually targets multi-office developers needing SSO and quarterly reviews.

About Testfit
TestFit is real estate feasibility software built for the concept stage, before anyone opens CAD. You map a parcel or draw a custom boundary, pick a typology, and it lays out roads, turning radii, parking stalls, and topography into a plan you can edit down to the last stall. The buyer is the deal team: developers vetting acquisitions, architects bidding for design fees, contractors wanting early cost signals, and planners running live 3D scenarios in public meetings. Recent releases add generative design for retail prototypes, flexible parcels for higher-yield subdivisions, an organic subdivision mode for irregular residential parcels, and a Path Offset Tool for consistent offsets. Typologies span parking, multi-family, single-family, industrial, retail, hotel, and data center. Layouts export to Revit, AutoCAD, SketchUp, Excel, or PDF, and Report Builder shares live feasibility reports. Pricing splits into two entry points. Parking Solver runs $195/month billed monthly for parking automation and quick feasibility, with unlimited users. Site Solver starts at $15,000/year billed annually and adds high-detailed building presets, generative design, custom unit types, MCP Connection, and a dedicated account manager. Site Solver Portfolio starts at $20,000/year with volume pricing, Enterprise SSO, and quarterly business reviews. Add-ons stack at $100–$170/month. TestFit stops at feasibility. It is not a BIM authoring tool and does not produce construction documentation, so it sits upstream of Revit rather than replacing it. That focus is the point: it is a decision engine for deals, not a drafting seat.
Behind the Verdict
Where TestFit earns its keep is deal velocity. One user describes sizing up a site in 10 minutes versus a 3–4 week wait for preconstruction drafts; another planner of one runs 15-minute scenarios live with elected officials. If your team vets sites often enough that the bottleneck is iteration speed rather than drawing quality, the platform pays back quickly. When to pick it: you are a developer or broker screening multiple parcels, an architect producing 2–3x more options on a fixed fee, or a contractor who needs parking, infrastructure, and earthwork takeoffs before scope is locked. The Yield Estimator and quantity takeoffs get you a defensible pro forma without a separate cost consultant. The catch is the tier gate. Generative design, custom unit types, high-detail building presets, and MCP Connection are Site Solver features at $15,000/year. If you mostly need parking studies and 2D/3D massing, start at Parking Solver and add Site Intelligence ($150/mo) or Pro Forma ($170/mo) as needed. Smaller firms doing one or two studies a quarter will struggle to justify even the monthly floor. Against alternatives: this is not a Revit or SketchUp replacement and does not produce construction documents. It sits upstream, feeding approved layouts into those tools. Teams comparing it to manual SketchUp massing should weigh the 30x-faster feasibility claims against the learning curve of TestFit's parameter logic. Real-world caveats. International coverage is uneven: parcel data, flood zones, wetlands, and zoning layers may not exist outside the U.S., and support and training run in English during U.S. business hours (9–5 CST). Check your region's data availability before committing to an annual Site Solver contract.

Real-world workflow fit
Concrete scenarios for the personas Testfit actually fits — and what changes day-one when you adopt it.
You map the parcel, run a multi-family typology at two unit mixes, and check the Yield Estimator against your pro forma before the LOI deadline.
Outcome: You drop sites that don't pencil in an afternoon instead of paying for a 3-4 week preconstruction draft.
You generate 2-3 layout alternatives for the RFP plus 3D massing in context, then export them as PDF and SketchUp for the submission.
Outcome: You respond faster with more viable options up front, which is the axis TestFit customers credit for winning fee work.
You turn on Site Intelligence for terrain cut and fill and zoning data, run quantity takeoffs for parking and earthwork, and hand the numbers to estimating.
Outcome: You flag grading and scope risk before the design is locked, using the takeoffs rather than a hand calculation.
Use Cases
- Evaluate a development site's feasibility and maximum unit yield before you tie up capital.
- Generate 2-3x more design alternatives for a client presentation on a fixed modeling budget.
- Validate pro forma assumptions against an actual building layout before purchasing land.
- Optimize parking layout and cost for a multi-family or mixed-use project.
- Compare zoning and environmental constraints across several candidate sites.
- Produce quantity takeoffs for parking, infrastructure, and earthwork to flag scope risk early.
- Run live 3D scenarios in a public meeting or with stakeholders.
- Model non-rectangular subdivisions or flexible parcels where a grid layout would waste yield.
Limitations
- Site Solver starts at $15,000/year billed annually, and Site Solver Portfolio at $20,000/year billed annually, which is a real commitment for individuals or small firms.
- Parking Solver is $195/month billed monthly, and the three add-ons stack on top: Site Intelligence at +$150/mo, Pro Forma at +$170/mo, and MCP Connection at +$100/mo.
- Generative design is available only on Site Solver, so the capability most buyers are evaluating sits behind the annual tier.
- The pricing page notes that some data layers — parcel data, flood zones, wetlands, zoning information — may not be available in all countries, and that support and training are English only during U.S. business hours.
- Users unfamiliar with real estate feasibility workflows face a learning curve, since the tool assumes fluency in unit mix, parking ratios, and yield targets.

Setup time & first value
How long it actually takes to get something useful out of Testfit — broken out by persona, not the marketing-page minute.
A Parking Solver subscriber with familiarity in feasibility work gets to a first editable site plan in an afternoon: watch the virtual training, import a parcel or draw a boundary, pick a typology. Site Solver adds a dedicated onboarding and account manager, which shortens the path for teams new to the tool. Budget extra time if you also need Site Intelligence or Pro Forma wired up to an existing
Switching to or from Testfit
How to bring data in from common predecessors and how to get it back out — written for the switcher, not the buyer.
- →From SketchUp massing-by-hand: draw the boundary, pick the typology, and let the solver place parking and roads before exporting back to SketchUp for detail.
- →From Excel-only feasibility: link your existing workbook through the Pro Forma add-on so the layout and the financials stay in sync.
- →From preconstruction team drafts: map the parcel and generate the initial plan in-house, then push approved layouts to Revit for documentation.
- ↗To Revit: push approved site layouts directly into Revit for design and documentation development.
- ↗To AutoCAD: export layouts for consultants who work in a CAD pipeline.
- ↗To SketchUp: export files to develop site plans further and produce presentation renderings.
