Navigating Planning Permissions in Sussex: A Homeowner's Guide

A typical Sussex village.

When dreaming of your perfect home in the beautiful Sussex countryside, it’s essential to understand the planning permissions that can impact your project—especially if your property sits within the High Weald National Landscape in Wealden, a conservation area, or an Area of Outstanding Natural Beauty (AONB). At Karenna Wilford Architects, we guide homeowners through the complexities of local planning regulations to bring their visions to life.

Understanding Planning Permission in Sussex

Planning permission in Sussex is a vital step for homeowners looking to build, extend, or renovate. Local councils and planning authorities carefully manage development to protect the unique character of the region, which includes picturesque villages, rolling landscapes, and historic buildings.

When Do You Need Planning Permission?

You typically need planning permission if you are:

• Building a new home

• Extending or significantly altering an existing property

• Changing the use of a building

• Developing on protected land

However, projects may fall under permitted development rights if they meet specific criteria. It’s always best to confirm with your local planning authority, as restrictions can vary, especially in sensitive areas.

Special Considerations: Conservation Areas and AONB

Conservation Area Regulations

If your home is in a conservation area, additional controls are in place to preserve the historic or architectural significance of the surroundings. Common restrictions include:

• Limitations on the size and style of extensions

• Strict design guidelines for windows, doors, and roofing materials

• Additional scrutiny for demolitions or external alterations

At Karenna Wilford Architects, we specialise in sympathetic designs that honour these local characteristics while delivering modern functionality.

AONB Building Restrictions

Building within an Area of Outstanding Natural Beauty (AONB)—such as parts of the High Weald National Landscape — means your project must have minimal visual impact on the landscape. Key considerations include:

• Building height and scale

• Use of local, natural materials

• Preservation of sightlines and green spaces

We can help you design sensitively to ensure your home enhances, rather than disrupts, the surrounding beauty.

Navigating the South Downs National Park Authority

The South Downs National Park Authority (SDNPA) oversees planning in one of the UK’s most treasured landscapes. Gaining planning permission here often requires:

• Detailed landscape impact assessments

• Biodiversity and sustainability considerations

• Pre-application consultations

Working with architects who understand the SDNPA’s priorities can significantly smooth the process and improve the chances of approval.
