Two ways in. One answer you can act on.
Come to us with a scheme and we appraise it. Or bring just the site and the Optimiser finds the strongest option. Both end in the same defensible report, so you can start before you know exactly what to build.
Pin a site or draw your plot and get an instant read on the key constraints. Free, no sign-up — and you keep a branded PDF snapshot.
Run the free checkI've got a scheme in mind
You know roughly what you want to build. We pressure-test it.
- 1Tell us the schemeDwellings, development type, housing mix and storeys — as much as you have.
- 2We appraise that schemePlanning judgement, viability and constraints, all keyed to your numbers.
- 3You get a defensible readWhere it stands, where the risk sits, and what to commission next.
- 4Optional: a second opinionAdd the Optimiser to see whether the site could do more than your scheme.
Help me decide what to build
You've got the site, not the scheme, and that's a fine place to start. We find the strongest option, then test it.
- 1Give us the site and your prioritiesViability, yield, speed or risk — tell us what matters most.
- 2The Optimiser ranks the optionsDwelling count, mix and type, worked for your site and its policy.
- 3We test the recommended oneWe run the full economics on it, so it is a position we stand behind, not a guess.
- 4You get the same defensible readThe recommended scheme, the alternatives, and what to do next.
We read your site, then find what fits.
Access, setbacks, constraints, the lot. You start from where you are now, and there is always a way through.

The same defensible answer.
Whichever way you come in, you are not left guessing. You land on one report, built to be tested and backed by a named person.
Four scope tiers, from a quick screening to a submission-ready pack. You pick the depth.
Adversarial quality control, then a named human check. Chartered sign-off on request.
Policy cited by paragraph and reasoning grounded in the appeal record, not recalled.

What each step is, and is not.
It reads public open data for England. A general guide, not site-specific advice, and not covered by professional indemnity insurance.
For the Optimiser route we find the best option and run the full economics on it before we stand behind it. We do not promise the maximum.
Where a scheme drawing is offered it is concept-stage, to show the response to the site — not a finished design.
You are not stuck.
