## Summary
A s73 application to enlarge an approved B2/B8 scheme on an industrial-estate edge by about 917 sqm. The extra floorspace would remove most of a TPO tree belt along Goldington Road. Dismissed for harm to character and appearance. The inspector closed the letter with the S4 "substantially outweighed" formula even though the site sits inside the settlement and no heritage or specific refusal policy was engaged.

## Issues and findings
- **Transition.** The Framework was not put back to the parties: "the relevant policy approach has not fundamentally changed" (DL ¶2).
- **Character and trees (DP3(1) / N3): FAIL.** The tree group "makes an important contribution to the character and appearance of the area, by providing a substantial verdant break in the otherwise continuous row of development along Goldington Road" (DL ¶7). The proposal "would harmfully diminish the contribution that the band of trees makes to the area" (DL ¶10), and the future growth of replacement planting "cannot be relied upon" (DL ¶11). It conflicts "with the Framework where it requires that development is well-designed, responds to its context, so that it integrates with and enhances its surroundings" (DL ¶13).
- **Benefits.** Energy efficiency, reuse of a vacant site, business growth and BNG all count, "However, the previously approved scheme would provide the same benefits, albeit to a slightly lesser degree" (DL ¶15).

## Planning balance
"when assessed against the national decision-making policies in the Framework, the benefits of the proposal are substantially outweighed by the adverse effects" (DL ¶19). Conflict with the development plan as a whole.

## What made the difference
The extant permission. Because it already delivered most of the benefits, only the extra increment counted, and that could not offset the loss of a visible TPO belt. Category C trees and a limited remaining lifespan did not remove their townscape value.

## Transferable points
- Low-category (C) TPO trees with a 20-40 year life can still be an "important contribution" to character. Replacement planting projected to outgrow them "cannot be relied upon" (DL ¶7, 11).
- Where an extant permission already secures the benefits, only the incremental benefit of a variation weighs in the balance (DL ¶15).
- The S4 "substantially outweighed" test can be run for employment development inside a settlement on character grounds alone (DL ¶19).

## Policy findings
- **DP3(1): fail.** unlabelled — conflict "with the Framework where it requires that development is well-designed, responds to its context, so that it integrates with and enhances its surroundings" (DL 13); DP3(3) "should be refused" wording not used
- **N3: fail.** code mapped by harvester — conserves and enhances existing natural features of visual value (DL 13); loss of most of TPO Category C group giving "substantial verdant break" on Goldington Road (DL 7, 10)
- **S4(1): fail.** code mapped by harvester — "when assessed against the national decision-making policies in the Framework, the benefits of the proposal are substantially outweighed by the adverse effects" (DL 19)
- **E2: benefit.** code mapped by harvester — extra industrial/logistics floorspace for identified need, better use of vacant site; but the approved scheme delivers the same benefits "albeit to a slightly lesser degree" (DL 15)

## Key facts
- TPO tree group mostly Category C, agreed 20-40 year retention span (DL 7)
- Only a small part of the tree band would be retained; replacement planting would never match depth and canopy (DL 8, 11)
- Parties not re-consulted on the 2026 Framework; "relevant policy approach has not fundamentally changed" (DL 2)
