Article 4 Directions

A Simple Introduction from Our Experience

Here’s a scenario we encounter regularly at London Extend. A new client comes to us, excited about their project. They’ve done their homework on the government’s Planning Portal and know that their proposed 3-metre rear extension falls squarely within Permitted Development (PD) rights. In theory, they shouldn’t need full planning permission. Yet, after our initial due diligence, we have to deliver some unexpected news: they do, in fact, need to submit a full planning application.

The reason? A designation called an Article 4 Direction.

Understanding this powerful local planning tool is absolutely essential for any homeowner or developer in London. It’s a perfect illustration of how planning is intensely local, and how relying on generic, national guidance alone can lead to costly mistakes. It is precisely this type of hyper-local knowledge that forms the bedrock of our service.

The Concept in Plain English

So, what exactly is an Article 4 Direction?

Think of it this way: the government sets the 'standard rules' for development across England via Permitted Development rights. An Article 4 Direction is a legal tool that allows a Local Planning Authority (LPA) to issue a 'local rule' that overrides the standard ones for a specific, designated area.

Its sole purpose is to remove specific Permitted Development rights.

It is critical to understand that an Article 4 Direction does not ban development. It simply removes the automatic right to carry it out. This means you must submit a full planning application for works that your neighbour on the next street over could do without one. This gives the LPA control, allowing them to assess the proposal against their local planning policies to ensure it's appropriate for the area's specific character.

LPAs use these directions to protect qualities they value. Common reasons include:

• Protecting Architectural Character: In areas with a very uniform architectural style, such as Victorian terraces or post-war housing estates, a Direction might be used to control extensions, porches, or the changing of windows to preserve that consistency.

• Controlling Conversions to HMOs: In areas with high rental demand, many councils use Article 4 Directions to remove the PD right to change a family home (Use Class C3) into a small House in Multiple Occupation (HMO - Use Class C4).

  
  

• Safeguarding Employment Areas: To protect town centres, some LPAs remove PD rights that allow offices or shops to be converted into residential flats.

  
  

• Strengthening Conservation Areas: They can be used within Conservation Areas to provide an extra layer of protection, controlling minor changes like painting brickwork or altering front garden boundaries.

  
  

How Article 4 Directions Work in Practice

An Article 4 Direction is a formal legal instrument. The key thing to know is that they are always highly specific. A Direction does not remove all PD rights. It will clearly list the exact classes of development from the General Permitted Development Order (GPDO) that are being withdrawn.

For example, a Direction might only remove your right to erect a porch but leave your right for a rear extension intact. This is why it’s not enough to know an Article 4 Direction exists; we have to read the specific document to understand exactly what is and isn’t controlled.

The process of dealing with one is clear:

1. The Professional Check: Before a single line of a design is drawn, our first action on any new project is to conduct a thorough search of the LPA's website and interactive planning maps. We identify every designation affecting the property, from Conservation Areas to, crucially, any Article 4 Directions. This is non-negotiable due diligence.

2. A Change in Strategy: If a Direction is in force that covers the work you want to do, our strategy immediately pivots. We can no longer seek a simple Lawful Development Certificate (LDC).

3. The Full Planning Application: We must now prepare and submit a full planning application. This is a more detailed undertaking. It requires a robust Design and Access Statement that makes a compelling case for your project, arguing how it complies with the LPA's specific Local Plan policies. We must positively address the very reasons the Article 4 Direction was put in place.

How This Impacts Your Project in London

Article 4 Directions are not a rare or obscure planning quirk in London; they are a widespread and increasingly common tool used by boroughs to manage intense development pressure. From Richmond and Kingston protecting their suburban character to Islington and Lambeth managing the impact of conversions, they are a fundamental feature of the capital’s planning landscape.

The practical impact on your project is significant. A full planning application, when one was not expected, means a longer and more uncertain process. The outcome is no longer a simple legal 'yes' or 'no', but a subjective decision based on the planning officer's assessment of your proposal against local policy.

Common Pitfalls We've Seen

• The Planning Portal Trap: Relying solely on the generic advice of the national Planning Portal website. It's a great starting point, but it does not hold the specific details of every local Article 4 Direction.

• Making Assumptions: Assuming that if a property is not in a Conservation Area or Listed, then all PD rights automatically apply. This is a dangerous assumption.

• Not Reading the Fine Print: Simply being told "there's an Article 4" and abandoning a project, without reading the Direction to see what it actually restricts. You may find your specific project is unaffected.

• Buying a Property Uninformed: This is the most costly mistake. Purchasing a property with the intention to extend or convert, without having a professional carry out these checks first.

Our Concluding Advice

An Article 4 Direction is the ultimate proof that all planning is local. It represents the council taking back direct control over development to protect the unique character of a neighbourhood—the very character that may have attracted you to it in the first place.

It should not be seen as a "no" to your ambitions, but rather as a request from the council to "let's discuss this properly." It makes the planning process more complex and raises the stakes, but it does not make your project impossible.

Identifying these directions at the earliest possible stage is the cornerstone of a low-risk, professional approach to property development. It allows for a clear, realistic strategy from day one and avoids wasted time and money pursuing a route that is legally blocked.
