Feasibility Report

What Feasibility Report does

Upload an IFC or Rhino model, add a few planning assumptions, and get a developer-facing feasibility report: an area summary, a unit and use schedule, a planning-risk screen, likely consultant reports and buildability flags, as a one-page PDF. This version is for England only — the planning rules are England's, so do not read the results as advice for another country.

Coverage:

England only

Input:

.ifc or .3dm

Output:

Report + one-page PDF

How it works

The report is deterministic and runs in your browser: areas, units and the schedule are read from the model, then checked against England's planning rules and a set of buildability prompts. Only the optional written developer summary uses AI.

• Areas and the use schedule are read from the model, not typed in (add an area override only if the model has none).
• Planning-risk and buildability items are decided by fixed England rules, each shown as OK, Watch or Flag.
• Everything except the developer summary is computed in your browser; the model is never uploaded.
• The written developer summary is the one AI step, and is Pro.

How to use it

1. Upload a model. Drop an .ifc or .3dm — the .ifc gives the full schedule, the .3dm gives geometry only.
2. Add the assumptions. Set the project name, primary use, site area, planned units, an optional max height and GIA override, and whether the site abuts sensitive neighbours.
3. Read the report. The report updates live: summary metrics, the unit / use schedule, the planning-risk screen, likely consultant reports and buildability flags.
4. Write the developer summary. Generate the AI-written summary on the Pro tier; the rest of the report needs no AI.
5. Compare options. Save alternatives and compare them under the same planning assumptions.
6. Download the PDF. Download the one-page report; it carries a watermark on the free tier.

Best used for

• A first read on whether a scheme works before detailed work starts.
• Backing a planning conversation with a consistent area summary and risk screen.
• Spotting which consultant reports a scheme will likely trigger.
• Producing a one-page PDF for a client or a landowner.

Not a substitute for

• A viability appraisal or planning advice — it is early feasibility intelligence.
• Sites outside England; the rules are England's.
• Replacing an accredited consultant or a quantity surveyor.
• Area certification or measured lease areas.

Known limits

• The answers depend on the model and the assumptions you type in.
• A .3dm gives geometry only; an .ifc carries the richer schedule.
• The planning screen is a screen, not a determination.
• The developer summary is AI-written and should be read as a draft.
