New Planning Rules, New Opportunities for Rural Housing

The new Framework now explicitly names ‘limited infilling within groups of houses’ as an acceptable form of development outside settlements. This is referenced in 'S5' under the 'National decision-making policies' and is part of a more structured approach to location-based approvals.

Under old policy, thousands of rural sites across the country sat in a frustrating planning limbo - plots that weren't obviously ‘isolated’ but didn't sit within a recognised town or village either. This lack of clarity left many homeowners without a predictable route to approval. The new Framework completely replaces this ambiguity with a clear, location-based system, unlocking distinct planning pathways for all rural sites.

These two policies under 'S5' are key…

• S5.1: 'Only certain forms of development should be approved outside settlements, as set out in the following list. These should be approved, unless the benefits of doing so would be substantially outweighed by any adverse effects, when assessed against the national decision-making policies in this Framework [...]; e. Limited infilling within groups of houses'
• S5.3: 'Development proposals comprising isolated homes, which are those lying outside settlements or groups of houses, should not be approved other than in accordance with policy HO11.'

Explainer: The New Spatial Hierarchy

To see how the 2026 Framework simplifies decision-making, look at how three typical rural plots shift from the old ambiguous system to the new, location-based framework:

• Within a settlement: Policy S4 applies, which means approval unless substantially outweighed
• Within a group of houses, outside a settlement: Policy S5.1(e) applies, and limited infilling within groups of houses' becomes an acceptable form of development
• Isolated, outside both settlements and groups of houses: Under Policy S5.3, proposals must satisfy HO11, the exceptional quality test - more on that later.

Studio Bark’s View

It never made any sense to have these sites as a planning ‘no mans land’, and this big shift from the previous Framework now means all rural sites have clearer routes to decision. This subtle change is a brilliant step in the right direction for sustainable, environmental homes, and will lead to better located development which supports rural communities. Studio Bark are experts in deciphering how different sites should be considered in policy terms, and we’ll happily walk you through our process in a free consultation call and explain the potential policy routes for your site.

The Evolution of HO11: A Definitive Rulebook for Outstanding Rural Architecture

While the core wording of the ‘Countryhouse Clause’ hasn’t changed, the way it’s applied has - and entirely for the better. If you’ve been following the policy over the years (we have, in depth!), then you’ll know there have been changes to the definition of ‘isolation’. This has historically led to inconsistency and confusion in how the policy was applied. It will now be easier than ever to work out when and how to apply Policy HO11.

Within the new 2026 NPPF, Paragraph 84 (originally Para 55, 79 and 80) has been renamed to Policy HO11. This follows the restructure from a purely numerical format to a named and numbered policy structure (the HO stands for Housing).

The Criteria for Approval: the HO11 Framework

Policy HO11 is in full below, but we’re mostly focusing on point e.:

"HO11: Isolated homes in the countryside
1. Development proposals for isolated homes in the countryside should only be supported where one or more of the following circumstances apply:
a. There is an essential need for a rural worker, including those taking majority control of a farm business, to live permanently at or near their place of work in the countryside;
b. The development would be appropriate enabling development to secure the future of heritage assets in accordance with policy HE4;
c. The development would reuse redundant or disused buildings and enhance its immediate setting, including proposals which would secure the long-term reuse of a vacant or underused listed building (subject to taking into account any harm to its significance, as set out in policy HE6);
d. The development would involve the subdivision of an existing residential building; or
e. The design is of exceptional quality, in that it:
i. is truly outstanding, reflecting the highest standards in architecture, and would help to raise standards of design more generally in rural areas; and
ii. would significantly enhance its immediate setting, and be sensitive to the defining characteristics of the local area.'

- Paragraph HO11, NPPF 2026

What Defines an ‘Isolated’ Home?

Rather than leaving the meaning of ‘isolated homes’ ambiguous, a description has now been provided:

"Development proposals comprising isolated homes, which are those lying outside settlements or groups of houses, should not be approved other than in accordance with policy HO11."

- S5.3, NPPF 2026

This means every single rural site should now definitively be covered under one policy or another, removing the guesswork.

National Frameworks Take Precedence to Contradictory Local Policies

Councils will also no longer be able to write their own local planning policies that reword, tighten or add extra conditions to the national rules. Previously, councils could adapt national policy to local circumstances in their local plans, for example, by adding stricter tests for new homes in the countryside and contradicting Paragraph 84. National Policy now states that local plans must simply work alongside the national rules, not rewrite them.

Any existing local plan policies that conflict with the new national rules will carry very little weight when planning decisions are made, effectively making the national rules the only ones that matter on those issues.

Studio Bark's Rural NPPF Policy Expertise

We’ve made a name for ourselves for over a decade in this policy, creating exceptional homes across the country. We think the Framework offers an amazing route to creating extraordinary, environmental homes that will stand the test of time and become a new typology for tomorrow. The changes to 'isolation' over the years have created confusion for local authorities and designers alike. What’s brilliant is that the meaning of 'isolated homes in the countryside' is now set out in writing, and every rural site is now covered under one policy or another.

If you’re looking to understand how your site might sit within the new NPPF, we’d love to hear from you.

Of course, the new NPPF (National Planning Policy Framework) doesn’t just include changes for rural housing. It’s important to understand the bigger picture to identify where the more nuanced changes apply.

Complete structural overhaul

• The 2025 draft abandons the prose-paragraph format entirely in favour of a policy-code structure with named, numbered policies (e.g. PM1, S1, HO3, GB7).
• Plan-making policies and decision-making policies are explicitly separated within each chapter, making it clearer which applies to which context.
• Key required documentation is now included in the Framework, standardising the application process.

A New ‘Development Presumption’ Framework

• The familiar Paragraph 11 ‘presumption in favour of sustainable development’ is replaced by a more structured location-based approach.
• Policy S4 governs development within settlements (approved unless benefits are substantially outweighed by harm), while Policy S5 sets out an exhaustive list of development types that may be approved outside settlements.
• The concept of ‘settlements’, and whether a site sits inside or outside one, becomes the central gateway test.

New Plan-Making Processes (and Limitations)

• The new Framework formalises local plan type requirements, removing variety and introducing clear structures for spatial development strategies and supplementary plans.
• Local authorities must now adhere to a strict 30-month timetable and new gateway checkpoints to pass their local plans.
• Any existing local planning rules that contradict the new national framework will carry virtually no weight in decisions.

Development in the Green Belt

• The Framework builds on previous policy seeking to create a hierarchy of development within the Green Belt.
• A significant new addition is Policy GB7(h), which states that housing and mixed-use development walking distance from well-connected railway stations is not inappropriate development in the Green Belt, and no longer requires very special circumstances.
• A clearer definition of Grey Belt is also provided, stating it as land within the Green Belt that has been previously developed and/or does not actively assist in the purpose of reducing built-up sprawl, town merging, or preserving the setting of historic areas.
