Start with the planning framework
Planning decisions must follow the development plan unless material considerations indicate otherwise. The NPPF is an important material consideration, and its policies must be read together rather than selecting one supportive passage in isolation. [1]
For a useful application statement, identify the policies directly relevant to the proposal and explain how the drawings respond. A long policy list without an explanation is less helpful than a clear account of the actual issues.
The proposal and its surroundings
The assessment can cover use, scale, appearance, neighbouring living conditions, access, parking and other effects relevant to the site. Different projects raise different issues: an extension, a new house and a commercial change of use do not call for identical evidence. [2][3]
The officer also considers information from consultations and the application documents. Islington's published process describes officer assessment and the preparation of a report and recommendation. Do not assume that a favourable informal conversation replaces that recorded assessment. [3]
Evidence rather than assertions
Statements such as “there is no overlooking” or “the street already has extensions” need to be connected to the drawings and relevant circumstances. Ask which relationships or effects are genuinely in dispute, then provide evidence directed at those questions.
Previous permissions can help explain the site's history, but retrieve their approved drawings and conditions before treating them as comparable. A planning register provides the decision record; a photograph of a neighbouring building does not establish exactly what was authorised. [4]
Can conditions solve a concern?
A planning condition can address an otherwise unacceptable aspect only where it meets the applicable tests. Conditions must be necessary, relevant, enforceable, precise and reasonable. They are not a way to postpone an unresolved fundamental objection without adequate assessment. [5]
When an officer suggests a condition, ask what must be submitted or done, when it must happen and who will be responsible. Consider whether the requirement can actually be delivered within the intended design and programme.
Planning is not every approval
A planning decision does not replace building regulations approval. Matters addressed through technical building control still need to be dealt with through that process. The planning officer's assessment should not be mistaken for a check of construction calculations or every contractual and ownership issue. [6]
The practical aim is to make the planning judgement straightforward: an accurately described scheme, coordinated plans and evidence addressing the material issues, with unresolved matters clearly identified.
