Council Pre-App Checklist

A council-specific checklist and document pack builder that tells architects exactly what each local authority needs for a pre-application or planning submission, updated when rules change.

Read the full idea

Who pays
Architect or small practice owner who submits planning applications
The problem
In the buyer's words: 'Anyone else had a permit application delayed or rejected just because the reviewer couldn't find the info they needed?' and 'It depends entirely upon the building department / agency you're submitting plans to.' Every council wants different documents, forms and drawings, and the rules change without notice.
The gap
Existing tools are generic. Document management software for architects organises files but does not know what a specific council requires. GOV.UK gives national guidance, not per-council checklists. Proposal and practice management tools do not cover submission packs. Nobody has built a maintained, council-by-council
Already out there
  • PlanMan planman.app

    Lists document management software for UK architects. Organises documents but does not encode what each council requires for a submission.

  • GOV.UK Making an application gov.uk

    National guidance on what a planning application is. Does not give council-specific document lists or a pack builder.

  • MHCLG Digital blog mhclgdigital.blog.gov.uk

    Government post arguing planning applications should be treated as data. Shows the problem is known but no product for architects exists.

People asking for it
The big assumption
That councils' requirements change often enough and differ enough that architects will pay a subscription rather than keep their own notes and PDFs.
Test it this week
Pick 5 councils where the founder has contacts. Build a manual checklist for each in a spreadsheet. Ask 10 architects who submit there whether the checklist matches their experience and whether they would pay for it kept up to date. Count how many say yes and how many already have their own version.

Architect Fee Proposal Builder

A tool that helps small practice owners build staged fee proposals with scope boundaries and exclusions from their own past projects, so they stop undercharging and scope creep is easier to manage.

Read the full idea

Who pays
Small practice owner
The problem
In the buyer's words: 'The ONLY way to reduce proposed fees should be by reducing scope' and 'When you're undercharging for scope from day one, scope creep becomes inevitable.' Practice owners write each proposal from scratch, forget exclusions, and then absorb unpaid work.
The gap
Generic proposal tools like Plutio and Smart Pricing Table give templates and e-signatures but no architecture-specific scope library, no reuse of the practice's own past project data, and no staged fee structure tied to RIBA-style work stages. Monograph automates proposals for larger A&E firms but is not built around
Already out there
  • Plutio plutio.com

    Proposal software for architects. Handles fixed price, retainer and rush quotes but is a generic proposal tool, not built on the practice's own past project data.

  • Smart Pricing Table smartpricingtable.com

    Architecture proposal template with assumptions and exclusions. A template, not a system that learns from the practice's own projects.

  • Monograph monograph.com

    Proposal automation for A&E firms with CRM to content library to e-signature flow. Aimed at larger firms and not built around a small practice's own historical fees.

People asking for it
The big assumption
That small practice owners will trust and use a tool built on their own past project data rather than keep doing proposals in Word and Excel.
Test it this week
Ask 10 small practice owners to send you three past fee proposals. Build one new proposal for each by hand using their own past scope and exclusions. Ask if the result is better than what they would have written and whether they would pay monthly for it.
