Housing Delivery vs. Nature Recovery: 1.5 Million Homes and Biodiversity Targets
Summary
The government has committed to building 1.5 million new homes in England this Parliament while simultaneously committing to creating 250,000 hectares of wildlife-rich habitat, halting species abundance decline, and achieving 30by30 by 2030. Housing development takes land. Land is the primary scarce resource in both commitments. The Nature Restoration Fund (PIA 2025) is the government’s mechanism for reconciling these — but it is brand new and untested.
Parties
- MHCLG: 1.5 million homes; planning reform; 150 major infrastructure decisions
- Defra / Natural England: 250,000ha habitat; species halt; 30by30; SSSI condition
Nature of tension
Resource conflict + definitional conflict: Both commitments require land. Housing development, even with BNG, typically results in net habitat loss at the site level (BNG requires 10% net gain on a “like-for-like” basis, which can be achieved by off-site credits, not necessarily by preventing habitat loss locally). 1.5 million homes will require significant land release across England.
Additionally, the 30by30 commitment requires that 30% of land be “effectively conserved” — if large-scale housing development occurs in or adjacent to proposed 30by30 areas, designation may be compromised.
Evidence
From Spring Statement 2025:
NPPF changes will “increase housebuilding by ~30% by 2029-30… 170,000 additional homes.”
From EIP 2025:
“Restore or create 250,000 hectares of wildlife-rich habitat outside protected sites by December 2030.” “Halt species abundance decline by December 2030.”
From Planning and Infrastructure Act 2025:
“Nature Restoration Fund: concurrent development with habitat restoration at scale.” “Natural England prepares Environmental Delivery Plans for strategic conservation.” “Mandatory BNG for Nationally Significant Infrastructure from May 2026.”
From Natural England Action Plan 2025-26:
“Support housing, energy, transport infrastructure alongside nature recovery.” “Focus high-risk/high-opportunity casework: major infrastructure and large housing.” Natural England will “respond to Spending Review 2025 savings requirement.”
Severity: high
This is a fundamental resource conflict operating on the same land area over the same 5-year period. The tension cannot be fully resolved without either:
- Reducing housing ambition, or
- Accepting lower biodiversity outcomes, or
- Deploying the Nature Restoration Fund at sufficient scale and speed to offset development impacts at landscape level
Status: open
The Nature Restoration Fund (NRF) is the government’s stated resolution. But:
- NRF only gained Royal Assent December 2025
- Environmental Delivery Plans must be prepared by Natural England for each site
- Natural England is simultaneously facing Spending Review savings requirements and responding to Corry Review reforms — EDP preparation capacity is uncertain
- The Spending Review savings requirement creates a perverse dynamic: Natural England must process more EDPs faster with fewer resources
Resolution pathway
NRF at landscape scale could theoretically resolve this if:
- Natural England has sufficient capacity to prepare EDPs quickly
- Developer contributions fund genuinely additional conservation outcomes
- The SSEP and LNRS provide spatial planning guidance on where development is most/least ecologically damaging
Currently none of these conditions are fully established. The Strategic Spatial Energy Plan (2026) and Land Use Framework (late 2025) are the spatial planning tools meant to help.
