Do I need planning permission?

For the majority of UK gardens, no. The diagram below shows the exact permitted-development envelope.

Variables

The four things that affect planning.

Positioning

Where the room sits in relation to the house and aspect.

Height & Roofline

Eaves, ridge and how the roofline reads within the garden.

Boundary Proximity

Distance to fences and neighbouring lines.

Intended Use

A quiet office, studio or retreat — not a separate dwelling.

Typical UK garden layouts — suburban, corner and mature landscaped gardens with garden room positioning

On site

Every garden is different.

Every project begins with a site visit — a proper look at access, levels, boundaries and how the room will sit within the space.

Support

If planning is required.

Drawings, supporting statements and the application itself — prepared and submitted on your behalf.
