Summary

One house on the last open plot in the historic core of Ivinghoe, between a Grade I church, two Grade II buildings and the conservation area's focal junction. Dismissed. Within a settlement, so S4 applied; harm to the setting of the Grade I church and Grade II Kings Head and to the conservation area, carrying HE6(1) substantial weight, outweighed the substantial weight to one home despite a 3.73-year supply.

Issues and findings

Planning balance

S3(1)(a)/S4(1) "substantially outweighed" balance (DL ¶33). Benefits: HO7 substantial weight (3.73-yr supply), L2(1) substantial weight to better use of underutilised land (DL ¶34). Against: HE6(1) substantial weight to conservation, greater for Grade I. Note: DL ¶35 as written says "the adverse effects would not substantially outweigh the benefits of the proposal" — which reads as a drafting slip given the dismissal and DL ¶36 ("no sufficiently weighted material considerations"). The HE6(4) balance (DL ¶27) is the clear operative reasoning. Treat the S4 formulation in this letter with care.

What made the difference

The site's openness was itself part of the setting of a Grade I church and the conservation area's key views; a single modern house matching adjoining 20th-century infill would further erode that. With a Grade I asset involved, one home's benefits could not tip the HE6(4) balance. A site outside key views or not contributing to Grade I setting would have favoured approval given S4 and the shortfall.
