Development feasibility
Test the building before you buy the land.
Draw the plot and record what the rules allow. URBN Planning turns it into a programme, a 3D massing and a quarterly appraisal, with every figure traced to its source.
A short film: two people discuss a plot over a map, a designer tests a block massing on screen, the massing rises on the empty site, and it resolves into a finished building. The imagery is illustrative.
Why it exists
A feasibility study is usually a spreadsheet, a site plan and a folder of PDFs. By the time the committee meets, nobody can say where the numbers came from.
URBN Planning keeps the site, the assumptions, the massing and the appraisal in one model. Every figure can be traced back to its source, and every decision keeps the working it was made on.

From massing to building
What the rules allow, before anyone draws it.
The massing is generated from the controls you record — plot ratio, coverage, height, setbacks — and measured against every one of them. It shows what the land can hold long before an architect is appointed. Drag across the image to compare.
Illustrative imagery. URBN Planning produces the massing and the numbers behind it; the architecture is still the architect’s job.
What it does
Everything the study needs, in one auditable model.
The work usually spread across a spreadsheet, a site plan and a folder of PDFs — held together, with the reasoning intact.
Programme and massing in one model
Turn a target area into unit mixes, net areas and parking, then generate a massing that is measured against your recorded controls: plot ratio, coverage, height, floors, setbacks and open space.
Inputs that carry their source
Plot ratio, setbacks, rents, build costs, interest — each value records where it came from, how confident you are and when it was checked. Change one and the original stays, with the reason for the change.
A quarterly appraisal, not a black box
Quarterly cash flows from land payment to exit, with IRR, NPV, margin on cost and residual land value. Financing, sensitivities and every intermediate figure stay visible.
Alternatives, generated and ranked
Set a range for each use and let the platform search the mixes. Every candidate clears programme, planning, physical fit and finance before it is ranked against your objective.
Decisions that stay put
Compare up to ten scenarios against a base, then record the review and approval with a reason. Approved revisions lock, so the numbers behind a decision cannot drift afterwards.
Measured office floor planning
Lay out floors with rooms, furniture, doors and cores in real metres, check circulation and seats, stack levels into a building, and export CAD DXF or a scaled A3 sheet.
Figures in the illustrations are examples, not results.
How it works
Four steps, and the evidence follows you through all of them.
Establish the site
Draw the boundary on the map, import GeoJSON or type the coordinates. Area and perimeter are measured in a projected coordinate system, not guessed from a screenshot.
- A measured boundary with area and perimeter
- One site record shared by every scenario
Record the assumptions
Planning controls, market evidence, costs and finance terms, each saved with its source and your confidence in it. Nothing is assumed on your behalf.
- Sixteen planning controls, each with its source
- Rents, costs and finance terms with confidence levels
- A change history that keeps the original value
Calculate and test
Programme, 3D massing and a quarterly appraisal run from the same inputs. When an input changes, stale results are labelled, never quietly reused.
- GFA, net areas, units or keys and parking
- A massing checked against every recorded control
- Quarterly cash flow with IRR, NPV and residual land value
Compare, decide, export
Rank the options against a base, record the review and approval with a reason, then export the decision with its working.
- Up to ten scenarios compared side by side
- Approvals that lock the revision they approved
- A stamped PDF memo and an Excel workbook that reconciles
Being straight about it
What this is not.
Most of the risk in a feasibility study is in what a tool quietly assumes. Here is where ours stops.
It does not invent planning rules
You record the controls that apply and where they came from. The platform enforces them consistently and shows the source beside the result.
It does not value your scheme
Appraisals are arithmetic on your assumptions. A valuation, a lender's view or a planning approval still comes from the people qualified to give it.
It does not design the building
Massing is conceptual: repeated floorplates within your controls. It tests whether a programme fits, not how it should look.
Pricing
Priced per person, not per project.
Test as many sites as you like. Every plan includes the full calculation engine, the evidence trail and the exports — the difference is how many people work together.

Questions
The things people ask before they trust a number.
Something else on your mind? Ask us — a person answers.
What does URBN Planning actually calculate?
Site area and perimeter from your boundary; a development programme (GFA, net areas, units or keys, parking) from your mix and efficiencies; a generated or manual massing checked against your recorded planning controls; and a quarterly appraisal covering CAPEX, GDV, profit, margin on cost, project IRR, NPV, residual land value, financing and sensitivities.
Does it include the planning rules for my city?
No, and it will not pretend to. You record the controls that apply — plot ratio, coverage, heights, setbacks, parking — together with the source you took them from and how confident you are. The platform then enforces them consistently and shows that source beside every result. It does not verify regulations for you.
Does this replace a feasibility consultant or valuer?
No. It is a modelling and record-keeping tool. Outputs are planning-grade estimates from the inputs you provide, not a valuation, a planning approval, an architectural design or investment advice.
Who can see our data?
Only people you invite to your organisation. Projects, scenarios and evidence belong to that organisation, access is checked on every request, and viewers cannot change anything. We do not sell data or share it with advertisers.
Do you train AI models on our projects?
No. The Advisor answers from your saved calculations using the platform's own deterministic engines. No external AI provider is called, and your project data is never used to train a model.
Can we get our work out again?
Yes. Stamped PDF decision memos and Excel workbooks whose formulas reconcile to the saved results, CAD DXF and scaled SVG drawings of office floors, and plain JSON. Decision exports keep their checksum and can be downloaded again at any time.
What happens when a scenario is approved?
The decision summary freezes the results it was based on, and the approved revision locks. To explore a change you clone the scenario, which keeps the approved record intact and auditable.
What do we need to run it?
A current desktop browser. There is nothing to install, and 3D views run in the browser. Phone screens show a read-only summary; the workspace needs a laptop or larger screen.
