Planning guide

Which planning-application documents matter

The decision notice establishes the outcome, approved drawings define the scheme and the officer report usually explains the planning judgement. Design statements and specialist reports add context but should not be confused with the authority’s conclusion.

At a glance

Outcome: Decision notice
Physical scheme: Existing and proposed drawings
Reasoning: Officer or committee report

A reliable process

How to approach the question.

01Confirm the document belongs to the correct application and revision.
02Prioritise decision, drawings and officer reasoning.
03Extract searchable text from PDFs while preserving the original file.
04Use specialist reports for the issue they address and note any missing documents.

Worked example

A privacy question

The proposal description may say only “rear extension”. Drawings reveal a terrace, while the officer report and condition specify a privacy screen. Document-level evidence changes the interpretation of the precedent.

What this does not prove

Council document portals can block or expire direct links.
Scanned PDFs may need OCR and can produce extraction errors.
Applicant statements are evidence submitted in support, not the decision itself.

Method used

Confirm the subject property and distinguish applications at the address from wider local context.
Classify proposal type and outcome consistently, keeping pending, withdrawn and approved-with-conditions cases separate.
Give more weight to recent, similar and well-documented decisions; retain contradictory evidence rather than hiding it.
