Summary
Retrospective extensions, a three-storey annex and a garage block at a large house in the Newcastle Green Belt. Dismissed. The site was accepted as grey belt, but GB7(1)(g)(ii) failed because the family's needs were not evidenced to require development of this scale. Under GB7(1)(b) the additions were disproportionate to the 2003 "original" dwelling. The resulting spatial openness harm was substantial even though visual harm was very limited.
Issues and findings
- Transition. Determined under the current Framework without further consultation; the "changes to the Framework do not alter the substance of the main issues … or prejudice either party" (DL ¶2).
- GB7(1)(g)(i): PASS. "I am satisfied that it comprises grey belt land" (DL ¶12).
- GB7(1)(g)(ii): FAIL. "While family circumstances can carry weight, the evidence before me does not demonstrate an unmet need requiring development of the scale proposed" (DL ¶13). "As the criteria are cumulative, that conclusion is sufficient" (DL ¶14).
- GB7(1)(b): FAIL. "the annex alone is of a scale broadly comparable to that of the dwelling originally constructed in 2003 … I consider it appropriate to treat it as an addition to the original dwelling" (DL ¶16).
- Openness. "the substantial increase in the amount of built form on the site results in a significant reduction in openness in spatial terms" (DL ¶18). Substantial weight (DL ¶19).
- Character: no harm. "Openness and character are distinct planning concepts" (DL ¶22).
- Ecology: moderate harm. Compensation was off-site and unsecured (DL ¶27-28).
Planning balance
GB6(2) VSC. For the scheme: moderate weight to family living arrangements and to the planning history (2017 permission), and limited weight to the UU, re-use of a residential site, mobility needs and security (DL ¶34). Against it: substantial weight to Green Belt harm and moderate weight to ecological harm. Not clearly outweighed (DL ¶35). The PSED was considered and dismissal found proportionate (DL ¶37).
What made the difference
Scale and evidence. The grey belt door was open, but limb (ii) requires an evidenced need for the type and scale of development proposed, and private family need was not documented. Under (b), an annex as big as the original house could not be proportionate.
Transferable points
- The grey belt route (GB7(1)(g)) can in principle be tried for non-housing residential additions. Limb (ii) then requires evidence that the need requires development of that scale (DL ¶13-14).
- Detached annexes and garages functionally tied to a dwelling are treated as additions for the GB7(1)(b) disproportionality test (DL ¶16).
- Heavy screening reduces visual openness harm but does not prevent substantial spatial harm (DL ¶18).
- No character harm does not mean no openness harm (DL ¶22).
- An occupancy UU does not reduce Green Belt harm that arises from physical scale (DL ¶32).
Policy findings
Policy codes are those of the National Planning Policy Framework (August 2026) unless a development plan is named.
| Policy | Finding | Weight | Note |
|---|---|---|---|
| GB7(1)(g)(i) | pass | long-established residential use with substantial built development; grey belt accepted (DL 12) | |
| GB7(1)(g)(ii) | fail | family, multi-generational, mobility and security needs genuine, but not evidenced to require development of this scale; site already had substantial accommodation (DL 13-14) | |
| GB7(1)(b) | fail | annex alone roughly the size of the 2003 dwelling (the fn40 "original" baseline); detached annex and garage treated as additions; disproportionate (DL 15-16) | |
| GB6(2) | harm | substantial | substantial spatial openness harm though visual harm very limited because of screening (DL 17-19) |
| DP3 | neutral | coherent design in a verdant plot; no character harm; openness and character distinct (DL 21-23) | |
| N2 | harm | moderate | woodland SLCI understorey cleared; BNG baseline disputed; off-site compensation not secured (DL 24-28, 35) |
Key facts
- Baseline for disproportion is the 2003 replacement dwelling and garage, per fn40 (DL 15)
- No volumetric assessment was supplied (DL 16)
- 2017 permission for extensions and annex, disputed as commenced; as built materially exceeds it (DL 9, 31)
- UU restricting annex to ancillary use given only limited weight because harm arises from physical scale (DL 32)
