Judgement stays human
Material planning, legal, structural and commercial decisions retain an accountable professional or project owner.
UK property-development operating platform
From plot
to proof.
Screen the site. Test the planning route. Model the numbers. Control delivery. Preserve the evidence behind every material decision.

What PlotU actually does
One workspace for the information work around a development
The software connects tasks that normally live across council portals, mapping sites, calculators, spreadsheets, folders and individual memory — while keeping the source and the human decision visible.
SITE
Understand what is there and what has to be proved.
BUILD
Control cost, change, risk and responsibility.
PROVE
Preserve the evidence and the decision trail.
Platform
Use the module the decision actually needs
Every card below opens a working part of PlotU. No teaser dashboard, fake live data or invented property metrics.
SITE · Live sources
Site Intelligence
Resolve the postcode and authority, screen official England Planning Data constraints, then open satellite, Street View, OS, title, flood and sold-data evidence.
Build a site dossierSITE · Planning
Planning Route Checker
Tell PlotU what you actually want to build. It separates permitted development, prior approval and full-planning fallback, then shows blockers, unknowns and evidence tests.
Check a proposalSITE · Commercial
Development Appraisal
Model GDV, residual land value, maximum bid, build cost, finance, profit, tax, CIL and downside sensitivity with deterministic arithmetic and visible assumptions.
Model the numbersBUILD · Control
Project Controls
Maintain risks, variations, decisions and quote comparisons without quietly turning discussion into approval. Signed-in projects now persist those records in the cloud.
Open my projectsPROVE · Evidence
Private Evidence Room
Store authorised project files privately, record the SHA-256 fingerprint and retain the exact evidence trail behind the project record.
Open Evidence RoomPROVE · Reporting
Decision Pack
Export the maintained project record as structured JSON, spreadsheet-compatible CSV and print/PDF, with a fingerprint for the assembled pack.

The framework is now the actual product architecture.
A site does not begin with a chatbot. It begins with what is known, what is not known, what the source says, what the numbers do, and who owns the decision.

Screen before spend
Location, planning route, constraints, title, technical unknowns, appraisal and evidence plan.
02BUILD
Control before drift
Quotes, costs, risks, changes, approvals, decisions and the record of who owns what.
03PROVE
Record before memory fades
Private evidence, document fingerprints, decision history and exportable project packs.
Cloud workspace
Projects that follow you across devices
Persistent projects
Create once; return from another device.
Cloud project controls
Risks, variations, decisions and quotes persist per project.
Private evidence
Project-scoped storage with SHA-256 fingerprints.
Decision packs
JSON, CSV and print/PDF exports from maintained records.
New · PlotU workspace
The project record is no longer trapped in one browser.
Create a secure account when you want continuity. Your public planning and calculator tools still work without login; the cloud workspace is for the durable record behind a real scheme.
Professional boundary
AI can accelerate the work without becoming the accountable decision-maker
PlotU is deliberately designed around evidence, visible assumptions and deterministic calculations. The model can help interrogate the work; it does not become your planner, solicitor, architect, engineer, QS, valuer or lender. The published method library also contains 16 complete chapters explaining how the operating system is used and where professional verification remains essential.
Sources stay visible
Missing dataset coverage is never converted into a positive conclusion.
Arithmetic stays deterministic
Calculators compute from the assumptions you enter rather than asking an AI to guess the maths.
AI stays assistive
Use it to challenge assumptions, identify unknowns, structure research and draft questions for professionals.
Implementation
Use PlotU yourself, or configure the operating system around a live business
The software is the core product. Advisory work is for teams that want their own information flows, review rules, project controls and evidence standards designed around real schemes.
£495
Development Intelligence Session
A working session on a live site, scheme or bottleneck. We map where AI genuinely helps, where it does not, and what to do first.
From £1,250
AI Property Workflow Audit
A structured review of how information actually moves through your business — from site sourcing to handover — and where it leaks.
From £2,950
Property AI Implementation Sprint
We build and land two or three working systems — not slideware. Document interrogation, planning research, procurement comparison or reporting.

Start on a real site
One postcode is enough to begin.
Resolve the location, screen the planning evidence, then take the scheme only as far as the decision requires.
