Summary

Permission in principle for one to nine dwellings on a bungalow plot near Houghton Regis. The appeal was dismissed. The inspector found the site to be grey belt and met all the GB7(1)(g) limbs, so the scheme was not inappropriate development. But the unilateral undertaking secured Chilterns Beechwoods SAC mitigation below the current tariff. Adverse effects on the SAC's integrity could not be ruled out, and a PIP cannot lawfully be granted for "habitats development". A separate costs decision (local copy PINS-6007334-costs.pdf) refused the appellant's costs application.

Issues and findings

Transition. The parties had the chance to comment on the 2026 Framework and on the 2024 and 2025 HDT results (DL ¶5).
Grey belt: ACCEPTED. The site-specific assessment overrode the Green Belt study's parcel rating. The roads, M1 and vegetation "strongly contain and enclose the site. The highways, noise and associated infrastructure such as street lighting, fencing, and hardstandings are urbanising influences" (DL ¶22). "the land makes a weak to moderate contribution to purpose a)" (DL ¶23).
GB7(1)(g)(i)-(iii): PASS. "There is a lit footway to Chalton a modest distance away where there are a small range of facilities and bus stops to larger settlements … This limits the need to travel, particularly by private car, and offers a genuine choice of transport modes" (DL ¶25). There was no need to assess openness: "which is implicitly taken into account in this exception" (DL ¶27).
Habitats / N6(1)(a): FAIL. "it is of fundamental importance the UU legally secures the correct adequate contribution before a PIP is consented" (DL ¶15). "necessary and adequate mitigation to prevent LSEs must be secured at the PIP stage, for it to be approved" (DL ¶12).

Planning balance

S5 (S5(1)(h)/(j) mentioned hypothetically). Benefits got full weight, with HO7 substantial weight to homes and a supply of about 3.93 years (DL ¶29-30). But the breach of the Habitats Regulations and the PIP Order "attract weight of a very high order against the scheme … substantially outweigh the benefits of the proposal for any number of dwellings in the range proposed" (DL ¶32).

What made the difference

A drafting failure. The Green Belt case was won: a contained plot, enclosed by the M1 and roads, with a lit footway to village services. The appeal failed only because the UU's SAMMS and SANGS figures were below the Council's current tariff. A correctly drafted UU would very probably have led to the appeal being allowed.

Transferable points

A site-specific assessment can override a strategic Green Belt study parcel rating for purpose (a), where roads and motorway infrastructure contain the site (DL ¶20-23).
A plot 250 m from an urban extension, seen as "a modest separate discrete scheme", is not sprawl of a large built-up area (DL ¶21).
A lit footway to a village with a small range of facilities and buses satisfies GB7(1)(g)(iii) for a small scheme (DL ¶25).
Openness is "implicitly taken into account" in the GB7(1)(g) exception (DL ¶27).
For a PIP, Habitats mitigation must be fully secured at the PIP stage. Out-of-date tariffs in the UU are fatal (DL ¶12-16).

Policy findings

Policy codes are those of the National Planning Policy Framework (August 2026) unless a development plan is named.

Policy	Finding	Weight	Note
AnnexB:grey-belt	pass		250 m from Houghton Regis North urban extension; contained by B579, access road, M1, trees and bunding → "weak to moderate" contribution to purpose (a) despite GB study parcel scoring strong; (b), (d) agreed (DL 19-23)
GB7(1)(g)(i)	pass		limited scale, containment, relationship to development, level of need (DL 24)
GB7(1)(g)(ii)	pass		no five-year supply (c.3.93 years) = fn41 unmet need (DL 25, 29)
GB7(1)(g)(iii)	pass		lit footway to Chalton (small range of facilities, bus stops); reasonable walking distance to part of Houghton Regis; highway access for up to 5 dwellings OK (DL 25-26)
GB7(1)(g)(iv)	not-engaged		not major (DL 26)
N6(1)(a)	fail		within 12.6 km ZoI of Chilterns Beechwoods SAC; UU contributions (SAMMS £182.49, SANGS £3,205/£4,273) below current tariff (£202.54, £3,565/£4,750) → LSEs not ruled out; PIP cannot be granted for habitats development (Art 5B PIP Order) (DL 7-17)
S5	fail		breach of Habitats Regs / PIP Order "weight of a very high order" → substantially outweighs benefits for any number in range (DL 30-32)
HO7	benefit	substantial	homes towards evidenced need; full weight to benefits (DL 29-32)

Key facts

Bungalow plot with garden and outbuildings. Enclosed by trees and bunding, and beyond them by the B579 on two sides, an access road and the M1
The 2017 Green Belt Study rated the wider parcel HR2 as strong for purpose (a). The inspector found this site weak to moderate
The Habitats mitigation UU used superseded (lower) per-dwelling tariffs, and the appellant accepted the figures were wrong
Mitigation must be secured at the PIP stage, not deferred to technical details consent (DL 12)
Costs application by the appellant refused (separate costs decision)
