Defending Countryside and Village Character
Horsham District covers 530 square kilometres of West Sussex, stretching from the market town of Horsham south through the villages of Warnham, Storrington, and Steyning into the South Downs National Park, which encompasses 93 km² of the district’s southern parishes. Across the district there are 39 conservation areas and approximately 1,800 listed buildings — a heritage landscape shaped by medieval villages, Wealden farmsteads, and the sandstone vernacular that defines the area. The Horsham District Planning Framework (2015) remains the adopted development plan, with a replacement Local Plan covering 2021–2038 currently under examination. That transitional policy position demands careful engagement with both adopted and emerging policies when objecting to planning applications in the district.
Planning Voice has prepared objection letters in Horsham District, addressing unauthorised Gypsy and Traveller sites, a replacement countryside dwelling, and a householder extension in the town of Horsham itself. Our objections in the district have raised material grounds including harm to countryside character, loss of light, overbearing impact, loss of privacy, unsustainable location, and conflict with the district’s strategic approach to Gypsy and Traveller accommodation.
Horsham District retains a strong settlement hierarchy, with development outside defined built-up area boundaries resisted unless it falls within specific exceptions. We have objected to proposals on sites deep in the open countryside that sought to introduce suburban-scale built form into a rural landscape. Proposals to replace recessive single-storey timber buildings with two-storey brick-and-tile dwellings on elevated ground significantly increase the massing, height, and domestic character of a site. Such transformations are incompatible with the surrounding countryside setting and can introduce harmful overlooking of neighbouring cottages from new first-floor windows. The development plan requires development outside settlement boundaries to protect and conserve rural character.
Horsham District’s strategic approach to Gypsy and Traveller accommodation identifies allocated sites sufficient to meet projected need. We have objected to retrospective changes of use for caravans and associated parking on non-allocated countryside land, arguing that allowing development on such sites would undermine the strategic framework. We have raised the impact on residential amenity, the oversubscription of local schools, and the absence of adequate highway access. Larger retrospective applications present an even more acute conflict where sites lie along narrow lanes with no footpaths, no lighting, and no public transport connection — functionally isolated from every local service.
Within the built-up area of Horsham itself, we have objected to proposed first-floor additions and two-storey rear extensions on existing bungalows in culs-de-sac where the single-storey roofline limits mutual overlooking between neighbours. Proposals to add a full first floor and two-storey rear projection introduce new elevated windows with direct views across adjoining gardens, causing a material loss of privacy that the original bungalow form was specifically designed to avoid. The resulting bulk and proximity along shared boundaries creates an overbearing and enclosing effect, with consequential loss of light to neighbouring rear gardens and conservatories.
Approximately 93 km² of Horsham District falls within the South Downs National Park, where the South Downs National Park Authority acts as the local planning authority rather than Horsham District Council. Parishes such as Storrington and Sullington, Washington, and parts of Upper Beeding lie within the Park boundary. In these areas, applications are determined against the South Downs Local Plan (2019), which places great weight on conserving and enhancing the landscape and scenic beauty of the National Park. Proposals that would cause significant harm to the National Park’s special qualities face a strong presumption against permission. If the development affecting you falls within the National Park boundary, we will advise which authority and which policy framework applies.
The Horsham District Planning Framework (2015) provides the policy framework for assessing applications across the district outside the National Park, with a replacement Local Plan currently under examination.
If a planning application in Horsham District affects your property — whether in the town of Horsham, the villages of Warnham and Billingshurst, or the rural parishes within the South Downs National Park — we will assess your case free of charge and advise whether there are material planning grounds to object. Our Chartered Town Planners prepare each letter around the specific policies of the HDPF or the South Downs Local Plan that officers will apply when determining the application. Contact us with the application reference for a same-day assessment.

The Horsham District Planning Framework (HDPF), adopted in November 2015, remains the current development plan. A replacement Local Plan covering 2021–2038 is under examination but has not yet been adopted, so the HDPF’s policies carry full weight in planning decisions. For the southern parishes that fall within the South Downs National Park, the South Downs Local Plan (adopted 2019) applies instead, with the National Park Authority acting as the local planning authority.
Yes. The HDPF provides strong protection for land outside defined built-up area boundaries, resisting development unless it falls within specific exceptions such as agricultural buildings or rural exception housing. We have objected to applications in the countryside near Warnham on grounds that proposals introduced inappropriate suburban-scale development into the open countryside.
The HDPF requires that development does not cause unacceptable harm to the amenity of existing or future occupiers through overlooking, loss of light, noise, or overbearing impact. Proposals must also achieve a high standard of design that respects local character. We have objected to first-floor additions and two-storey rear extensions on bungalows because new upper-floor windows would introduce harmful overlooking of neighbouring gardens that the original single-storey form was designed to avoid.
Approximately 93 km² of Horsham District lies within the South Downs National Park, including parishes such as Storrington and Sullington, Washington, and parts of Upper Beeding. In these areas, the South Downs National Park Authority determines planning applications under its own Local Plan (2019), which places great weight on conserving landscape character and scenic beauty. If the application you wish to object to falls within the Park boundary, we will advise which authority and policy framework applies and prepare your objection accordingly.
Objections to Gypsy and Traveller sites must be grounded in material planning considerations, not the identity of the occupants. The HDPF sets out a strategic framework that identifies allocated sites to meet accommodation needs. Where an application proposes a site that is not allocated, located in an unsustainable position, or would cause landscape or amenity harm, there are legitimate planning grounds for objection. We have prepared objections in the Warnham area, raising issues including conflict with the strategic allocation approach, absence of highway access, landscape harm, and impact on residential amenity.
