What permissions do I need to build a dropped kerb?

A dropped kerb is a sloping point in the pavement to provide access by vehicle to a property. Dropped kerbs aren’t usually a planning matter although it is recommended that you contact your local authority to find out if planning permission is required, and you will need to make a specific dropped kerb application for a domestic vehicle crossing licence to your local authority.

Work to create a dropped kerb must be carried out by a New Roads and Street Works Act accredited contractor.

Do I need planning permission to add a garden office?

Rules governing outbuildings apply to sheds, playhouses, greenhouses and garages as well as other ancillary garden buildings such as swimming pools, ponds, sauna cabins, kennels, enclosures (including tennis courts) and many other kinds of structures for a purpose incidental to the enjoyment of the dwellinghouse.

If you are unsure if your planned building falls into the category of 'outbuildings' or if you are unsure if planning permission is required, please contact your local planning authority.

Outbuildings are considered to be permitted development, not needing planning permission, subject certain limits and conditions.

Do I need planning permission to upgrade to double glazed windows?

For houses, replacing windows with double glazing usually doesn’t require planning permission, provided the style and appearance are similar to the original. However, if you live in a flat/maisonette, listed building, or a conservation area, planning permission or listed building consent may be required, especially if the changes affect the external appearance.

Do I need planning permission to operate a business from my garage?

In most cases, yes - planning permission is required to operate a business from your garage. This is because the use would no longer be purely domestic, and the garage would be considered to have changed use from residential (Class C3) to a business-related use, which requires planning consent.

Do summerhouses or garden offices need building regulations approval?

If you plan to put up a small, detached building like a garden shed or summerhouse (classed as an outbuilding) in your garden, building regulations generally won’t apply if the building has a floor area under 15 square metres and does not include any sleeping accommodation.

For buildings with a floor area between 15 and 30 square metres, building regulations approval is usually not needed - as long as the building does not include sleeping accommodation and either:

  • it is at least one metre away from any boundary, or
  • it is built mainly from non-combustible materials.
