Planning Permission for Self-Builds: How to Get It Right the First Time

Starting a build, extension, or renovation is exciting. You've got ideas, sketches, and vision — but before any of it becomes reality, there's one crucial step: planning permission.
If you’ve never been through it before, it can feel overwhelming. Many people assume it’s just a case of submitting drawings and waiting for a yes — but the truth is, it’s rarely that simple.
That’s why I created my Design & Planning Permissions Package: to help self-builders and renovators avoid delays, rejections, and confusion by doing things right the first time.
Why Planning Applications Fail — and How to Avoid It
A lot of applications fall at the first hurdle — and most of it comes down to avoidable errors. Below are the top mistakes I’ve seen in 20+ years of construction and consulting, and how you can sidestep them.
1. Rushing the Drawings
Vague or incomplete drawings are one of the top reasons applications get delayed or rejected. Include site plans, elevations, sections, and material specs — make it easy for planners to say yes.
✅ Tip: Always include a proper location plan and block plan.
2. Not Checking Local Policies
Each local council has unique rules. What’s approved in one area might get rejected in another.
✅ Tip: Read your Local Development Plan and browse recent approvals in your area.
3. Misjudging the Timelines
Most applications take 10–16 weeks, not including re-submissions or specialist reports.
✅ Tip: Build in buffer time and never book trades before approval.
4. Forgetting About the Neighbours
Neighbours can derail your application with a single objection.
✅ Tip: Talk to them early. Show them your plans and be open to minor changes.
5. Assuming Planners Will “Figure It Out”
If your application isn’t crystal clear, it gets delayed — or denied.
✅ Tip: Include a short Design & Access Statement to explain the project clearly.
A Costly Mistake I’ll Never Forget
A few years ago, I helped a client submit a beautiful modern extension for an old cottage — only to be rejected instantly. Why? It was in a Conservation Area, and we hadn’t checked.
We had to redesign the whole thing, wasting time, money, and energy.
Lesson learned: never submit without checking local constraints first.
