Boundary Rules
Garden rooms must be carefully positioned within the residential garden and must not be placed in front of the principal elevation of the house.
The structure must remain within the residential curtilage of the property.
Placement should minimise impact on neighbouring properties.
Planning rules require garden rooms built under permitted development to be located behind the main house rather than in front gardens. The principal elevation usually refers to the front wall of the house facing the street. Outbuildings positioned in front of this line are generally not permitted development and usually require planning permission. Locating garden rooms in the rear garden helps preserve the character of residential streets and prevents front gardens from becoming dominated by additional buildings. Positioning the structure carefully can also reduce potential issues such as overshadowing or loss of privacy for neighbours. Many homeowners place garden rooms near the back of the garden where they have minimal visual impact on the main house and surrounding properties.
Exceptions: Garden rooms placed forward of the principal elevation or within front gardens will normally require planning permission.
Boundary distance rules help protect neighbouring properties from overshadowing, overlooking, and overbearing development. Structures built very close to boundaries are subject to stricter height limits to minimise their visual impact.
Height Rules
Development must comply with national permitted development height limits.
Height limits exist to prevent extensions or roof alterations from overpowering neighbouring properties or significantly changing the character of the surrounding area. Planning officers typically assess whether the proposed structure would appear dominant or intrusive when viewed from neighbouring homes or public spaces.
Even where a development falls within permitted development limits, larger structures may still require careful design to avoid overlooking or overshadowing nearby properties.
Depth Rules
Extensions must comply with national permitted development depth limits.
Depth limits restrict how far an extension can project from the original rear wall of the property. These rules help ensure that extensions remain proportionate to the original house and do not create excessive loss of light or privacy for neighbouring homes.
Local Planning Restrictions
Additional planning restrictions may apply in conservation areas.
Listed building consent is required for works affecting listed buildings.
What To Check Before You Rely On This Rule
- Garden rooms must be carefully positioned within the residential garden and must not be placed in front of the principal elevation of the house.
- Review local controls such as conservation areas, listed buildings before relying on the general rule.
- If the design is close to a limit, prepare measured drawings and consider written confirmation before work starts in Kensington and Chelsea.
