NPPF 2026 Update: What Does It Mean for Development and Landscape Design?

NPPF 2026 Update: What Does It Mean for Development and Landscape Design?

The revised National Planning Policy Framework (NPPF) came into force on 17 August 2026, setting out the Government's latest policies for planning, placemaking and decision-making on development proposals across England. While much of the media focus has been on housing delivery and planning reform, the updates also introduce some important changes for landscape architecture and landscape assessment, surface water management and development site design. These changes reinforce the growing importance of landscape-led planning and evidence-based assessment throughout the development process.

So, what does this mean for the work we do at Land Studio, and more importantly, what does it mean for our clients?

Landscape Assessments: A Greater Focus on Evidence

One of the most significant changes is the removal of the term "Valued Landscapes" from national policy. Instead, planning decisions will now focus on the conservation and enhancement of existing natural, visual, historic and ecological features, supported by robust and evidence-led landscape assessments.

For nationally designated landscapes, including National Parks and National Landscapes (Areas of Outstanding Natural Beauty), the policy position has become even stronger. Major development proposals should be refused unless exceptional circumstances can be demonstrated and clear public benefits outweigh any harm. Landscape assessments will therefore carry substantial weight during the planning balance.

This places an even greater emphasis on high-quality Landscape and Visual Impact Assessments (LVIAs) and strategic landscape planning from the outset of the development process.

Grey Belt Assessments: A More Detailed Approach

The revised NPPF introduces significant changes to how Grey Belt land is assessed.

Rather than relying on broad strategic analysis, assessments must now be site-specific and supported by clear evidence. Key changes include:

• Greater focus on individual Green Belt purposes rather than blanket assumptions.
• A refined definition of sprawl, placing greater emphasis on visual containment.
• A requirement to demonstrate meaningful inter-visibility when considering settlement coalescence.
• Clarification that villages are no longer automatically considered "large built-up areas".
• Increased expectations for high-quality green infrastructure and landscape strategies as part of any development proposal.

These changes create opportunities for some sites previously considered constrained, while also increasing the need for comprehensive landscape evidence to support planning applications.

Design and Placemaking Move Centre Stage

Perhaps the most transformative aspect of the new NPPF is the complete redrafting of Chapter 14: Achieving Well-Designed Places, alongside the introduction of new Design and Placemaking Planning Practice Guidance.

The Government has moved away from subjective design language and introduced a far more measurable, outcomes-based approach. Landscape is no longer viewed as an optional enhancement but as critical infrastructure that must be integrated into decision-making from the earliest stages of development. This is something Land Studio has championed for many years.

Seven measurable principles now form the basis against which development proposals may be judged:

• Liveability - provision of accessible, high-quality private and shared outdoor spaces for residents and users.
• Climate Resilience - development must demonstrate how design responds to climate risks and improves long-term resilience.
• Nature and Green Infrastructure - integration of multifunctional green spaces that support biodiversity, recreation and environmental performance.
• Sustainable Movement - creation of balanced places that reduce car dependency and provide strong connections to surrounding communities.
• High-Quality Public Realm- streets, squares and public spaces must be designed to maximise social, environmental and economic value.
• Inclusivity and Safety - public spaces should be accessible, socially connected and designed to promote safety and wellbeing.
• Local Identity - development must respond positively to local character, historic context, materials and the existing landscape setting.

The message is clear: successful developments will need to be landscape-led, place-sensitive and demonstrably aligned with these principles.

Higher Density Development and the Role of Green Infrastructure

Although the NPPF encourages significantly higher housing densities around transport hubs and railway stations, it is equally clear that this cannot result in uniform or poor-quality intensification.

Higher density development must be supported by contextual design and the integration of green and blue infrastructure from the outset. These elements can no longer be treated as separate design exercises but must form a fundamental part of the development strategy.

SuDS and Flood Risk: New Mandatory Requirements

The revised framework also strengthens national expectations around flood risk management and sustainable drainage.

All drainage designs must now comply with the 2025 National Standards for Sustainable Drainage Systems (SuDS) for both minor and major developments.

Naturalistic drainage solutions such as swales, rain gardens, retention basins and wetland features are expected to deliver multiple benefits, including flood attenuation, water quality improvements, visual enhancement, biodiversity gains and improved placemaking.

A major policy shift is the introduction of a presumption against the enclosure of existing watercourses. Where culverts already exist within development sites, developers will increasingly be expected to assess opportunities for their removal and restoration.

In addition, a Flood Risk Assessment (FRA) is now required for any site identified as being at risk from flooding from any source, including surface water and climate change impacts. This removes previous exemptions for minor and low-vulnerability developments.

Biodiversity Net Gain

Alongside the revised NPPF, updated Biodiversity Net Gain (BNG) requirements for smaller developments and nationally significant infrastructure projects came into effect on 6 August 2026. These changes further reinforce the importance of integrating ecology, landscape design and long-term environmental stewardship into development proposals from the earliest stages.

What This Means for Our Clients

The direction of travel is unmistakable. The planning system is placing greater emphasis on evidence-based decision-making, landscape-led design, green infrastructure and environmental performance.

For developers, landowners and planning consultants, this means that landscape considerations can no longer be addressed late in the process. Early engagement, robust assessments and integrated design strategies will be critical to securing planning consent and demonstrating compliance with the new framework.

At Land Studio, we see these changes as a positive step forward. They align closely with the principles we have always promoted: creating places that respond to their landscape context, support nature recovery, manage water sustainably and deliver long-term value for communities.

As the planning landscape continues to evolve, our team is ready to help clients navigate the new requirements, identify opportunities and create developments that are not only policy-compliant but genuinely successful places to live, work and visit.
