What is the 2.5m rule for garden rooms?

The 2.5m rule refers to UK planning regulations for outbuildings, including garden rooms. If your garden room’s eaves are no higher than 2.5 metres and it meets other size and location requirements, you usually don’t need planning permission.

This makes it easier to add a functional space like a home office, gym space or garden studio without complex approvals. Pod Space modular buildings are designed to maximise space while staying compliant with these rules.

Projects that can be delivered without the need for planning permission are usually known as "permitted development" which is often applicable to outbuildings. In many areas, garden pods fall under this category, which means they do not require formal planning permission; however, they will need to comply with specific criteria.

It’s always best to check as not every site is standard and there may be restrictions specific to your property or location which may initiate a requirement for planning permission.

If your garden is in a conservation area or you’re considering a large annexe that occupies a significant portion of the garden, you may need to apply for full planning consent. Pod Space’s architectural team can take care of the planning application for you, working with planning consultants and local authorities to manage the process.

When planning is required, we don’t just submit drawings; we supply all the detailed architectural and building regulation documentation. This formal planning service simplifies the process, particularly for use cases like a Living Pod.

In most cases, if you have Permitted Development rights, meaning you don’t need planning permission, the main guidelines to be aware of are:

As planning rules can vary depending on location (e.g., conservation areas, listed properties), we do recommend checking your local regulations.
