Summary

Outline scheme for up to 70 homes (50% affordable) on a Green Belt field at Oxhey Lane, on the edge of Watford Heath/Carpenders Park, in a district with a 1.2-year supply. Officers recommended approval. Three days after the new Framework was published, their addendum said the site was grey belt and also qualified under the new station route GB7(1)(h), treating Bushey station at about 1,100 m as "around 800m". Members refused 5-4. They held the site was not grey belt and that 1,100 m is not "around 800m". So the scheme was inappropriate, and the Golden Rules benefits did not amount to very special circumstances against Green Belt harm plus harm to a Grade II listed lodge.

Issues and findings

• Station route GB7(1)(h)(i): officers PASS, members FAIL. Officers: "Bushey Station is some 300m above the 800 meters but is considered to fall within a reasonable distance that would encourage people from the site to walk to the station. The station is easily accessible from the site by existing lit footpaths with safe crossing points" (Addendum ¶7.1.7). Members: "whilst Bushey was undoubtedly a well-connected station as defined by the new NPPF, its distance of c1100m from the site did not meet the test of 'around 800m'. Accordingly, there was a need for consideration to be given to GB(7)(1)(g)" (Minutes PC170/25).
• Grey belt: officers PASS, members FAIL. Officers found only a weak contribution to purpose (a) because the site is "enclosed by residential development … along all three sides" (Report ¶7.2.16). They also said the former footnote 7 heritage carve-out "had been removed from the new NPPF" (Minutes). The member who moved refusal said "the site made a strong contribution to the prevention of the unrestricted sprawl of a large built-up area … there was a strong argument that the site was not Grey Belt" (Minutes). Cumulative closure of c.90% of the gap by nearby permissions was argued. Officers answered that unstarted permissions could not carry weight.
• Sustainable location (TR3). Officers: lit footways, 30 mph road, hourly bus 346, contributions for evening and Sunday services (Report ¶7.2.37, ¶7.8.12). They conceded that "access to doctor's surgery would not be easily accessible on foot" (¶7.8.12). Several members said the station distance, the lack of a walkable GP, infrequent buses and few facilities within walking distance "meant that the site could not be considered sustainable" (Minutes). The final resolution still listed "sustainable location" among the benefits.
• Heritage HE6: harm. Low-level harm to the setting of Grade II Oxhey Grange Lodge. The Conservation Officer objected. Officers gave the harm significant weight but found it outweighed (Report ¶7.21.12–13; Addendum ¶7.3.4). Members added it as a refusal reason.
• Density L3. 41 dph against the 45 dph expected near a well-connected station. Accepted because of the pipeline buffer and the heritage set-back (Addendum ¶7.2.3). Objectors said the site could not be close enough to the station to use GB7(1)(h) and yet too constrained to reach that density.
• Prematurity / emerging allocation. Officers said refusal for prematurity was "a high bar" that was not met, and that an appeal would be judged on the evidenced 1.2-year supply (Minutes).

Planning balance

Officers: not inappropriate, so S5(5) applies. The significant weight to low-level heritage harm did not substantially outweigh the benefits: market housing (substantial), affordable (substantial), Golden Rules (significant), sustainable location (moderate) (Report ¶7.21.7 table; Addendum ¶7.5.7, corrected orally to the "substantially outweighed" wording). Members: inappropriate, so GB6(2) applies, with "very substantial weight" to Green Belt harm including openness. Benefits: market housing substantial, affordable substantial, Golden Rules significant, self-build moderate, sustainable development limited, infrastructure none, green infrastructure none. Green Belt harm plus heritage harm plus the unsigned S106 outweighed them.

What made the difference

The officers' approval rested on two generous readings: that 1,100 m is "around 800m" for GB7(1)(h), and that a contained greenfield site on the edge of Watford makes only a weak contribution to purpose (a). Members rejected both. They did not have to break the 1.2-year shortfall or the 50% affordable offer; they only had to push the scheme back into the VSC test, where Green Belt harm carries substantial weight. A site within about 800 m of Bushey, or officers' grey belt reasoning accepted, would have put the scheme in the S5(5) balance, where officers found low-level heritage harm could not "substantially outweigh" the benefits. Expect an appeal. It will test the "around 800m" reading.

Transferable points

• Officer reading: a walk of about 1,100 m (16 min) on lit footways with safe crossings was treated as "reasonable walking distance" under Annex B (Addendum ¶7.1.7). Members rejected this, and the question is untested at appeal.
• A new L3 density point can be used against a GB7(1)(h) claim: a site that relies on station proximity should reach the station-proximate density (Addendum ¶7.2.3; objector submissions).
• Officers treat the removal of footnote 7 from the grey belt definition as ending "heritage makes it not grey belt" arguments (Minutes PC170/25).
• Even with a 1.2-year supply and 50% affordable housing, members may find no VSC once they hold the land is not grey belt. The grey belt judgement is the pivot.

Policy findings

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

Key facts

• Council supply 1.2 years
• Bushey station c.1,100 m (16 min walk) from site; officers treated this as "around 800m"
• Site 2.7 ha greenfield grazing, enclosed by housing on three sides and Oxhey Lane on the fourth
• 50% affordable (71% rented), 7 self-build plots, Golden Rules met per officers
• Allocated (CFS13) in emerging Reg 19 plan, consultation still open at time of meeting
• Report written under Dec 2024 NPPF; addendum re-ran it under Aug 2026 Framework three days after publication
• Vote 5-4 to refuse against officer recommendation
