A quick guide to planning permission in Suffolk
If you're planning a home extension, renovation, barn conversion, new build or alterations to a listed building in Suffolk, chances are you'll need to engage with your local planning authority at some point. For many homeowners, understanding whether planning permission is needed - and how to get it - can feel like a complex and daunting process.
As a leading architect in Suffolk, Shiel Architecture works closely with local councils and has guided hundreds of clients through the planning process. This guide breaks it down clearly, so you know exactly what to expect — and how to get your project off the ground with confidence.

What is planning permission?
Planning permission is formal approval from your local planning authority to proceed with building works that fall outside standard allowances. It ensures that developments meet national guidelines and local policies around design, sustainability, impact on neighbours, and preservation of the local character.
In Suffolk, planning decisions are typically handled by:
-
West Suffolk Council
-
Mid Suffolk and Babergh District Council
-
East Suffolk Council
-
Ipswich Borough Council
Each area has its own planning nuances, especially when it comes to listed buildings, Conservation Areas, and Areas of Outstanding Natural Beauty like Dedham Vale and the Suffolk Coast.
Do I need planning permission?
You may need planning permission if you are:
-
Building a new home or dwelling
-
Extending your property beyond permitted development rights
-
Altering the appearance of your home (roofline, cladding, windows, etc.)
-
Converting a non-residential structure, like a barn or outbuilding
-
Developing near protected landscapes or listed structures
Some smaller home improvements fall under Permitted Development Rights, which allow you to build without full planning approval. However, there are specific size and location restrictions. In many parts of Suffolk — particularly rural and historic areas — Permitted Development Rights are limited or removed altogether through Article 4 Directions.
Top Tip: Always seek professional advice from a local architect in Suffolk to assess whether your plans require permission before starting any work.
How the planning process works
1. Feasibility & design
We begin with a detailed consultation and site assessment to understand your vision, identify constraints, and explore design possibilities that are most likely to gain approval.
2. Pre-application advice (optional but wise)
This informal step allows early feedback from the planning officer, improving your chances of success and helping shape a more acceptable proposal.
3. Full planning application
We prepare and submit all required documents, including:
-
Scaled architectural drawings
-
A Design & Access Statement
-
Site location plans
-
Heritage, ecology, or flood assessments (if required)
-
4. Consultation period (approx. 8 weeks)
The council opens your application for public comments and internal review. Neighbours may be consulted, and planning officers assess it against local policies.
5. Decision & Conditions
You’ll receive a decision notice with approval or refusal, sometimes with conditions (e.g. materials, landscaping). If refused, you can appeal or revise the design.
