Before starting plans for an extension, it’s worth taking a step back and checking a few key planning considerations. Many homeowners start designing first and only later discover planning restrictions.
These five checks can help you avoid unnecessary problems.
1. Does Your Property Have Permitted Development Rights?
Permitted development rights allow certain types of extensions without full planning permission. However, these rights are often restricted by planning conditions or property location.
Confirming whether your home still benefits from these rights is the first step.
2. What Has Already Been Built?
Permitted development rights relate to the original house. Previous extensions, outbuildings or alterations may already use up the development allowance.
You should note that work carried out by previous owners can affect what you’re allowed to build today.
3. Are There Planning Designations Affecting Your Property?
Some areas have additional planning protections.
Examples include:
- Conservation areas
- National Parks
- Areas of Outstanding Natural Beauty
- World Heritage Sites
- Covered by Article 4 Directions
Homes in these locations often face stricter planning rules.
4. Could the Extension Affect Your Neighbours?
Planning officers will consider impacts on neighbouring homes, particularly:
- Loss of daylight
- Privacy concerns
- Overshadowing
Considering these issues early can improve your chances of approval.
5. Is the Design Likely to Meet Local Planning Policies?
Each council has its own design policies that influence planning decisions.
These policies often cover:
- Extension size and scale
- Materials
- Parking requirements
- Garden space
Understanding these policies early can prevent wasted design work.
Get Clarity Before You Start
A Planning Report for Home Extensions reviews your property, planning history, and local policies to confirm exactly what may be possible.
