✓ Example — Supporting Statement

From:

Mr & Mrs David and Susan Thompson

42 Birchwood Avenue, Wilmslow, SK9 4HT

13 March 2026

To:

Planning Department

Cheshire East Council, Westfields, Middlewich Road, Sandbach, CW11 1HZ

RE: Planning Application Reference CE/2026/00847 — 42 Birchwood Avenue, Wilmslow — Proposed Single Storey Rear Extension

We write in support of the above planning application, which seeks permission for the erection of a single storey rear extension at the above address. This supporting statement sets out the context and justification for the proposals, and demonstrates compliance with relevant national and local planning policy.

The proposed extension measures 4.5 metres in depth by 6 metres in width, with a lean-to roof at a maximum height of 3 metres. Materials will match the existing dwelling — facing brick and slate-effect roof tiles — ensuring the extension is subordinate to and visually consistent with the host property.

With regard to national planning policy, the National Planning Policy Framework (NPPF, 2023) confirms at paragraph 130 that planning decisions should ensure that developments are sympathetic to local character and history. The proposals accord with this requirement...

Yours faithfully,

Mr & Mrs D & S Thompson

✕ Example — Objection Letter

From:

Mrs Patricia Holden

14 Oak Street, Oldham, OL4 1AB

13 March 2026

To:

Planning Department

Oldham Metropolitan Borough Council, Civic Centre, West Street, Oldham, OL1 1UG

RE: Formal Objection — Planning Application PA/2026/01234 — 16 Oak Street, Oldham — Proposed Two Storey Extension

I write to formally object to the above planning application. I am the owner and occupier of 14 Oak Street, the immediately adjoining property to the north, and I am directly affected by the proposals.

Overlooking and Loss of Privacy: The proposed first floor element includes two new windows on the north-facing elevation which will look directly into my rear garden. Policy H5 of the Oldham Local Plan requires that extensions do not result in undue overlooking of neighbouring properties.

Overshadowing: The two storey element will cast a significant shadow over my garden from mid-afternoon onwards, materially reducing its amenity value. This conflicts with the Building Research Establishment's Site Layout Planning for Daylight and Sunlight (2022)...

Yours faithfully,

Mrs Patricia Holden

📍 Step 1 of 4 — Your property details

We need to know where the property is so we can address the letter correctly to your local council.

💡

The council uses your address to find the application on their system. Getting this right is important — an incorrectly addressed letter may not be considered.

Your property addressInclude the full address including postcode

Your local councilWho do you pay council tax to?

Planning application referenceFound on your planning notice (optional)

🔨 Step 2 of 4 — About the proposed works

Tell us what you want to build. Don't worry about technical language — just describe it in your own words.

💡

The council needs to understand exactly what you're proposing. Our AI will translate this into planning terminology — the language that planners respond to.

💬 Step 3 of 4 — Your reasons and impact

This is where your letter becomes personal and persuasive. Be honest and specific — it genuinely does influence decisions.

💡

Planning officers are real people. A growing family, a health need, working from home — these genuinely do influence decisions.

Why do you need this?Your personal reasons — the more specific, the better

How will this affect your neighbours?Why it won't harm them, or steps taken to minimise impact

Anything else? (optional)

📷 Step 4 of 4 — Add your photos (optional but recommended)

Photos are embedded into your PDF as photographic evidence with captions — a powerful addition no other service offers.

💡

A photo of your current cramped kitchen or rear garden is worth a thousand words. Your letter will stand out.

📋 Step 1 of 4 — The application you're objecting to

Find the planning reference on the yellow notice posted near the property, or on your council's planning portal online.

💡

The planning reference number is essential — it allows the council to link your objection to the correct application.

What is your neighbour proposing?

⚖️ Step 2 of 4 — Your grounds for objection

Your objection must be based on material planning considerations — things the council is legally allowed to take into account. Personal preferences are not valid grounds.

💡

Valid grounds include: loss of privacy, loss of light, noise, traffic — not "I don't like the design" or property values.

Select every concern that genuinely applies

✓

Overlooking and loss of privacy

New windows or height will allow them to see into your home or garden

✓

Loss of natural daylight

The building will block sunlight to your windows

✓

Overshadowing

The building will cast shadow over your outdoor space

✓

Overbearing appearance

The building will feel oppressive from your property

✓

Out of character with the area

Design doesn't match surrounding properties

✓

Increased traffic or parking

More vehicles will cause congestion or block roads

✓

Noise and disturbance

The development will create noise affecting your quality of life

✓

Overdevelopment of the plot

Too much built on too small a piece of land

✓

Harm to trees or landscaping

Protected or significant trees may be affected

✓

Flood risk or drainage

More hard surfaces will increase flooding

📝 Step 3 of 4 — Describe your specific concerns

The more specific you are, the stronger your objection. Measurements, distances, times of day — all of these help.

💡

"The extension will be 1.5m from my fence and 7m tall, casting shadow on my garden from 2pm" is far stronger than "it's too big."

Describe your concerns in your own words

Anything else that strengthens your case? (optional)

📷 Step 4 of 4 — Add your evidence photos

A photo showing how close the extension is to your boundary, or your garden and the impact, speaks volumes to a planning officer.

💡

Good photos: your garden showing the boundary, the view from your windows, the neighbouring property from your side.
