Navigating Policy HO11 for Countryside Homes

Building a home of your own in the open countryside is a dream that many share. In general, national planning policy strictly protects rural landscapes from uncontrolled development. However, the planning system retains a pathway in Policy HO11 for the truly ambitious: an exclusive provision that allows for the creation of exceptional, one-off architectural masterpieces in isolated rural locations.

Known previously under former iterations like Paragraphs 84, 80, and 79, this framework is now formally designated as ‘Policy HO11: Isolated Homes in the Countryside’.

For clients and architects alike, Policy HO11 represents an incredible opportunity, yet achieving planning permission for a country house is still a formidable challenge. In this post, we explore what Policy HO11 means, what it demands of contemporary architecture, and how to successfully navigate its rigorous tests to bring a visionary rural home into being.

What is Policy HO11?

At its core, Policy HO11 exists to prevent the erosion or suburbanisation of open landscapes through generic suburban housing. Planners want to ensure that any new dwelling built far from existing towns, villages, or established settlement boundaries justifies its presence there.

The policy outlines a few specific circumstances where an isolated home may be permitted. These include essential needs for rural workers, heritage-led enabling development, the reuse of redundant or disused historic buildings, and the subdivision of existing residential structures.

However, the route that captures the imagination of people who desire a contemporary new home in the countryside is ‘Policy HO11(1)(e)’: the provision for homes of truly outstanding architectural design.

The High Bar: Understanding the Core Tests

If you wish to build an avant-garde or a contextual modern home in the open countryside via the design exception route, your proposal must clear a series of demanding hurdles. Local planning authorities and design panels will look for several distinct benchmarks:

1. Truly Outstanding Architecture

It is not enough for a proposed home to be “nice,” sustainable, or well-built. HO11 demands architecture of the highest calibre. The building must reflect cutting-edge design thinking, meticulous craftsmanship, and demonstrate a mastery of spatial proportion, light, and materiality. It should be a piece of architecture that pushes boundaries and contributes meaningfully to the wider architectural discourse.

2. Raising Standards in Rural Areas

A successful HO11 design should act as a beacon of quality. The policy requires that the project helps to raise standards of design more generally across rural areas. It demonstrates that contemporary, forward-thinking architecture can coexist with, and elevate, historic or vernacular rural contexts, rather than defaulting to pastiche or faux-historical imitation.

3. Significant Enhancement of the Immediate Setting

This is often where many proposals stumble. The house cannot merely “fit in” or quietly blend away; it must significantly enhance its immediate landscape. Whether through landscape restoration, ecological regeneration, or the creation of a striking yet harmonious dialogue between built form and nature, the site must be left in an environmentally and visually richer state than before.

4. Sensitivity to Local Character

Outstanding architecture under HO11 must be deeply rooted in its specific place. This requires extensive landscape, historical, and ecological research to understand the defining characteristics of the local area, be it local materials, regional topography, agricultural building traditions, or ecological micro-climates. The resulting home should feel as though it could only exist on that exact piece of land.

Why the Design Narrative Matters

When preparing an HO11 planning submission, the architectural drawings are only half the battle. The accompanying planning narrative and ‘design and access’ statement must tell a compelling story.

At Architecture for London, we approach these sites through deep listening. We ask:

• What are the historical layers of this landscape?

• How might a building best enhance this landscape, whilst being an exemplar for sustainability?

• What materials can be pulled directly from the earth or local vernacular to ground the structure?

When a design emerges directly from these site-specific constraints and opportunities, it transforms from a generic proposal into an organic response to the landscape itself. Planners and independent review panels respond favourably when they see a rigorous, intelligent design logic that respects both the environment and architectural integrity.

How do I obtain consent for a country house using Policy HO11?

Understanding the site’s potential

Firstly, not every site has the potential to succeed, irrespective of the house’s design. Policy HO11 states that a building has to be truly outstanding, while also improving its immediate surroundings.

Paradoxically, while some sites have been deemed too extraordinary to build on, others have been discarded because they are not beautiful enough. Therefore, buying a site and assuming you’ll be able to build your dream home is not an advisable approach.

Engaging in early dialogue

One of the biggest stumbling blocks for rural new build Country House approvals seems to stem from local authorities being afraid to set a dangerous precedent. As a Policy HO11 house is a rather unusual form of planning, many local authorities also struggle with a lack of experience, leading to a hesitancy to approve schemes.

Opening up dialogue early on in the project is therefore very important. Before submitting for consents, a scheme should be thoroughly discussed and developed. If a proposal is refused consent, there can be no design changes during any appeal process.

How should we approach our Policy HO11 house?

We would suggest that planning committees are more likely to support projects with the following specific criteria:

• The site has a backstory or personal narrative
• Technologies and ecological strategies are proposed that are unique to the site
• Non-virgin sites, i.e. somewhere where there used to be a house
• And, a subjective but crucial point: achieving a sense that the house ‘belongs’ and that the site ‘needs a building’

 

Policy HO11: a design-led process

Crucial to Policy HO11 is an architect’s ability to design individual projects of definable character. Appointing an architect with a focus on environmental design, experience in Passivhaus strategies and an enthusiasm for truly outstanding architecture will increase your chances of success.

From appointment, the architect will need to have a larger degree of executive power than in other projects. A Policy HO11 client should know that the brief to an architect should be deliberately ambiguous in terms of aesthetics and materiality. Beyond room requirements and an overall idea of size and budget, an architect should be allowed to develop a rigorous design with a strong response to a particular narrative.

Is Policy HO11 Right for Your Project?

Embarking on an HO11 journey requires patience, financial investment in specialist consultants (such as landscape architects, ecologists, and heritage experts), and a willingness to push creative boundaries. It is a path designed for clients who view their home as a permanent, habitable work of art.

Conclusion

Policy HO11 presents an exciting yet challenging opportunity for both client and architect. Whilst clients may not be able to shoehorn a previously conceived ‘dream’ design to fit the Policy HO11 criteria, the considered design approach required may result in a truly original, exemplary home. Key points to remember are as follows:

• This is not an easy venture, but the process has significant rewards if successful
• A dedicated team of professionals are required to navigate the waters of the NPPF
• A close dialogue with the local community and planning authority will increase a project’s chances
• There should be a strong connection to the site and local context, with a convincing narrative
• Extensive surveying and specialist research are required
• You should consider how the building significantly enhances its context.
• Every project is unique, all planning authorities are different, and there is no single ticket to success

Between 2012 and 2018, there were just 113 applications under Paragraph 79. 66 were approved; 59 at committee level, 7 on appeal. This gave a low success rate of 58%, while the overall residential planning success rate is 87.5% (data from a study by Studio Bark, featured in The Architects Journal).

Since its iteration as Paragraph 79, the framework for building new homes in open countryside has been improved to make the process easier. One key change is that the design no longer needs to be ‘innovative’. This alteration to the policy made it easier for clients wishing to self-build a country house, as historically this had been one of the more difficult parts of the planning process.  

Paragraph 79 was renamed to Paragraph 80 in July 2021, when the government published the revised NPPF.

The NPPF was again updated in 2023 and the policy retained, although moved to Paragraph 84. The wording remained unchanged. Further revisions of the NPPF in 2024 and 2025 retained the paragraph 84 policy unaltered.

The August 2026 revision of the NPPF revised saw the provisions that allow for isolated dwellings in the countryside moved to Chapter 6, Ho11: “Delivering a sufficient supply of homes”.
