NPPF Policy HO11, Changes to Paragraph 84
NPPF Policy HO11: What Replacing Paragraph 84 Means for Rural Homes
NPPF Policy HO11 has replaced the former Paragraph 84: Isolated homes in the countryside. The change took effect when the government published the new National Planning Policy Framework on 17 August 2026.

Landowners, developers and clients considering rural sites now need to understand: Is this just a change of policy number or have the rules themselves changed?
The exceptional architectural design route remains largely intact. However, the new framework gives greater clarity around what constitutes an isolated home. It also changes some of the policy relating to heritage assets and listed buildings.
Why did Paragraph 84 become HO11?
The government first proposed the change in its draft NPPF, published for consultation on 16 December 2025. The consultation closed on 10 March 2026. The consultation documents described proposed Policy HO11 as a redraft of Paragraph 84. They also identified changes relating to the removal of the term “optimum viable use” and the reuse of vacant listed buildings.
HO11 now forms part of the adopted national planning framework.
What did Paragraph 84 allow, and what does HO11 allow now?
Under the previous NPPF, Paragraph 84 generally sought to avoid new isolated homes in the countryside. However, it allowed development in five specific circumstances:
- an essential need for a rural worker to live at or near their place of work;
- certain development involving heritage assets;
- the reuse of redundant or disused buildings;
- subdivision of an existing residential building; and
- a new home of exceptional architectural quality.
The final category led to the term “Paragraph 84 house”. It became widely used for individually designed countryside homes seeking permission through the exceptional design route.
Policy HO11 retains the same broad structure. It supports isolated homes where one or more of the defined circumstances apply. These include rural worker accommodation, appropriate enabling development involving a heritage asset and reuse of redundant or disused buildings. They also include subdivision of an existing home and an exceptional new architectural proposal.
HO11 does not create a general opportunity to build houses in the open countryside. A proposal still needs to establish a specific planning route.
What is now considered an isolated home?
One of the most useful changes is clearer guidance on what “isolated” means. The new framework describes isolated homes as those lying outside settlements or groups of houses. A property does not automatically become isolated simply because it sits outside a defined settlement boundary. The physical relationship between the site and nearby development also matters.
A plot may sit beyond a village settlement boundary but still form part of an identifiable group of houses. Another site may sit further away from surrounding development and fall more clearly within the definition of an isolated location. This can affect the planning strategy.
An early site assessment should therefore consider the relationship between the plot, nearby housing and the wider settlement pattern.
Exceptional design under HO11
The exceptional design route associated with Paragraph 84 remains within Policy HO11. For this route, the proposed home must be of exceptional quality. The policy requires it to be truly outstanding and reflect the highest standards in architecture. It must also help raise design standards more generally in rural areas.
The design must significantly enhance its immediate setting and respond sensitively to the defining characteristics of the local area. The move to HO11 does not make it significantly easier to gain permission for a new house in an isolated countryside location.
There is no standard architectural style that automatically satisfies HO11. The policy focuses on design quality and the way the proposal responds to the site. Relevant considerations could include landscape character, topography, views, local materials and building traditions. Ecology, biodiversity, trees and hedgerows may also influence the design, alongside energy performance, access and the history of the surrounding landscape. These elements should support one clear design concept. A standard house type placed on a rural plot would be unlikely to demonstrate the site-specific response expected under HO11.
The requirement to significantly enhance the immediate setting also remains important. Possible measures could include restoring degraded landscape, reinstating hedgerows or field boundaries and removing poor-quality structures. Habitat improvements or a long-term landscape management strategy may also contribute to the wider planning case.
These are not prescribed requirements within the NPPF. They show how architecture and landscape design can support a stronger proposal.
Heritage assets and redundant buildings
The treatment of heritage assets is one area where HO11 differs more clearly from former Paragraph 84. The previous policy referred to development that would represent the optimal viable use of a heritage asset. It also referred to appropriate enabling development that would secure its future.
HO11 now refers to appropriate enabling development that would secure the future of heritage assets. It also recognises development that would secure the long-term reuse of a vacant or underused listed building. This gives clearer recognition to projects that bring neglected listed buildings back into long-term use. The usual heritage considerations still apply.
A proposal involving a listed building will still need to assess its historic fabric, character and setting. It must also consider any harm caused by alterations or conversion. The wording may be particularly relevant to rural estates, historic farmsteads and other redundant listed buildings.
HO11 also continues to recognise the reuse of redundant or disused buildings that are not listed. The development must enhance the building’s immediate setting. This may apply to barns, agricultural structures and other rural buildings where residential reuse is being considered.
Other routes, including permitted development rights or local planning policies, may also apply depending on the site and building.
What does HO11 mean for current and future projects?
Any scheme prepared or submitted as a Paragraph 84 proposal should now be reviewed against NPPF Policy HO11. The final NPPF became a material consideration in decision-making from 17 August 2026. Applications submitted before that date but not yet determined may therefore need to respond to the new framework.
For an exceptional design proposal, much of the underlying architectural case may remain relevant. The key exceptional-quality test has been retained. Planning statements and other reports should still use the current policy references. The site’s status as an isolated location should also be reconsidered against the new wording.
New sites should undergo an early feasibility assessment before substantial time and cost are committed to the design. This should consider the site’s relationship with nearby settlements, local planning policies and landscape or heritage designations. Access, ecology, existing buildings and the potential for landscape enhancement should also form part of the assessment.
Architecture and planning need to develop together
For an exceptional HO11 home, the architectural concept should respond to planning policy, landscape and environmental characteristics from the outset. A stronger planning case will usually develop alongside the design and respond directly to the qualities of the site.
Replacing Paragraph 84 with NPPF Policy HO11 has not reduced the high threshold for isolated rural homes. The 2026 framework gives clearer guidance on isolation and introduces important changes for heritage assets and vacant listed buildings.
Landowners considering an isolated countryside site should therefore establish which part of HO11 could apply before progressing into detailed design.
