Can I draw my own plans for planning permission?
So, technically, yeah—you can absolutely draw your own plans. There's no law saying you need a fancy architect or some professional. But here's the thing: your drawings have to hit certain standards. Like, they need enough detail so the local planning folks can actually figure out what you're trying to do. Sure, doing it yourself saves cash, but mess up the measurements or leave stuff out? That's a gamble. Honestly, it might bite you later if you're not careful.
What are the basic requirements for self-drawn planning plans?
Your plans gotta be clear, right? Like, drawn to scale—usually 1:100 or 1:50. You'll need existing and proposed floor plans, elevations, a site location plan (that's at 1:1250 or 1:2500 scale), and a block plan showing boundaries. Don't forget dimensions, materials, and any changes to how the building looks from outside. Most councils have a validation checklist online. Check it. Seriously, it spells out everything they want.
What are the common mistakes when drawing your own plans?
Inaccurate measurements or scaling
Even tiny measurement errors? They can tank your application or get you a request for re-dos. Grab a tape measure, maybe a laser measure, and graph paper. Or use free software like SketchUp or DraftSight. Just be precise, man.
Missing or incomplete information
People forget north arrows, scale bars, boundary lines—happens all the time. Check your council's planning portal for their specific submission stuff. Don't wing it.
Ignoring local design policies
If your plans clash with neighborhood character or conservation area rules, they'll get rejected fast. Look up your area's local plan and design guide before you even start drawing. Saves headaches.
When should you hire a professional instead?
Look, if your project's a mess—like, structural changes, listed buildings, flood zones, or multiple extensions—maybe get help. Or if you're clueless about technical drawing or local policies, an architect or planning consultant can boost your odds. Professional drawings for a house extension? Usually £500–£2,000. That might sting, but a rejection costs time and money too. Weigh it up.
What free or low-cost tools can help you draw your own plans?
There's free stuff out there. SketchUp Free, Floorplanner, SmartDraw. Some councils even offer templates or online submission portals with guidance. For simple projects, graph paper and a ruler work fine—just make sure everything's to scale and labeled clearly. No shortcuts.

Checklist for submitting your own planning plans
- Include a site location plan at 1:1250 or 1:2500 scale with red line boundary.
- Provide existing and proposed floor plans at 1:100 scale with dimensions.
- Show elevations (front, side, rear) at 1:100 scale with materials annotated.
- Add a block plan at 1:500 scale showing site layout and neighboring buildings.
- Include a north arrow, scale bar, and date on every drawing.
- Ensure all measurements are in metric (millimeters or meters).
- Check your local council's validation checklist for additional requirements.
- Consider adding a design and access statement if needed.
Frequently Asked Questions
Can I use online templates for planning plans?
Yeah, loads of councils and websites offer free templates. But make sure they're current and match your council's rules. Templates often need tweaking for your specific project.
Do I need to include a design and access statement?
Not always, but for listed buildings, conservation areas, or big developments, it's required. Check your council's guidance; a simple statement can help explain what you're doing.
What happens if my plans are rejected due to poor drawings?
You can resubmit corrected plans, but you'll lose the application fee (usually £172–£462 for a house extension). Honestly, better to get it right the first time or ask for pre-application advice.
Can I draw plans by hand instead of using software?
Sure, hand-drawn plans are fine if they're neat, to scale, and have all the info. Use a ruler, pencil, and graph paper for the best results.
Short Summary
- You can draw your own plans: No law requires a professional, but plans must be accurate, to scale, and complete.
- Check local requirements: Use your council's validation checklist to avoid missing key details like site plans or elevations.
- Beware of common errors: Inaccurate measurements, missing north arrows, or ignoring local design policies often lead to rejection.
- Consider professional help for complex projects: If your project is large, in a conservation area, or involves structural changes, hiring an architect may save time and money.
