One of the most significant changes to planning policy in recent history is the concept of grey belt land. It opens the door for developments on land that was previously locked behind a green belt designation. This can provide some fantastic opportunities for new developments. However, sites must showcase they are actually appropriate to develop. We want to have a closer look at that here, focusing on the tests planners use to assess land. Then, if you want to work with top architects in London on a project, you can get in touch with us.

The planning practice guidance (PPG) for grey belt land specifies five key tests. The testing ensures there is sufficient justification to warrant development. Most importantly, it confirms that developing the land aligns with planning goals.

Will there be any harm?

Firstly, it is important to test to make sure that developing the land won’t compromise the original fundamentals of the green belt land. For example, it must not lead to urban sprawl, merging of towns, encroachment on the countryside, or loss of heritage or character. Crucially, the development must also not compromise remaining green belt land in the area.

Is there a need being unmet?

Land is more likely to get approval for redevelopment if there is clear evidence that the proposal meets a key need. Generally this relates to housing. If a project will deliver a sufficient amount of new homes where housing delivery is not meeting targets, it passes the test.

Is the location sustainable?

One of the most important things to think about with any kind of project is how connected the site is. We’ve seen many projects struggle because they create new housing but fail to deliver infrastructure to support it. In fact, some new developments become entirely reliant on private car ownership. This is something every stakeholder should consider. We can factor it in to projects if you want to work with leading architects in London.

In terms of grey belt, there are key tests for sustainability and connectivity. Sites should have existing services and infrastructure. There should also be access to public transport. Ultimately, the development should be low carbon and sustainable.

Does it comply with golden rules?

There are a number of key rules for every site. Most importantly developments must deliver at least 50% affordable housing. If local policies are in place, such as a Local Plan, with different requirements, the amount of housing must be 15% above the policy requirement. Additionally, projects must provide new green space to benefit the area. Finally, the development must enhance the infrastructure in the area.

Is it legally grey belt?

Finally, the last test is to confirm that the site actually complies with the formal criteria to designate it as grey belt. Crucially, it must not strongly serve green belt principles like preventing urban sprawl. It must also not be in flood risk areas, include heritage assets, or feature land with environmental designations such as scientific interest.

Discuss plans with top architects in London

If you’re planning a proposal for any kind of site, it is important to do all the background stuff first. This includes ensuring the land is actually appropriate to build on. There is no point progressing with designs and proposals if the plot itself is fundamentally unavailable.
