Refused once, redesigned, and allowed the second time.

A side and rear extension in Westerham, Kent, was refused as cramped and out of character. It wasn't the first time this homeowner had tried - an earlier, larger version of the same idea had already been dismissed on appeal. This time, a scaled-back redesign succeeded.

The application

✓Site: a semi-detached house on Westways, Westerham, within the Kent Downs National Landscape (formerly known as an AONB).
✓Proposal: a part two-storey side and rear extension with a rear dormer, plus a porch replacement and loft conversion.
✓Decision: refused by Sevenoaks, then allowed on appeal - the second time a version of this scheme had gone to the Planning Inspectorate.

Why the council refused it

Sevenoaks' single refusal reason focused entirely on the two-storey side extension: by reason of its siting, width, form and orientation, it would appear cramped and out of character with the existing pattern of development in the street, contrary to the council's Allocations and Development Management Plan and Core Strategy policies.

What the Inspector found

The Inspector found the side extension would be set back from the existing front elevation and would remain subordinate to the host house, with a visual gap to the neighbouring property comparable to an existing gap between a similar pair of houses elsewhere on the same road. The scheme also met the council's own Residential Extensions SPD standards - a set-back position, a lower roofline, and the minimum 1 metre gap to the adjoining property.

Crucially, the Inspector directly compared this scheme to an earlier version of the same idea that had already been dismissed on a previous appeal at the same site. That earlier scheme had included an additional single-storey element and a higher ridge line, and had been found cramped and dominant. This version dropped the single-storey element, set the two-storey part back further, and lowered the ridge line - and although the width stayed the same, the Inspector found the overall scale and massing was no longer cramped or dominant as a result.

Where the council's assessment fell short

A few gaps stand out when you compare the refusal reason to the Inspector's decision:

The refusal didn't engage with the council's own design standards. The scheme actually complied with the council's Residential Extensions SPD on setback, roof height and minimum gap - the "cramped and out of character" conclusion wasn't tested against the council's own numeric guidance for exactly this kind of extension.

A directly comparable local example wasn't addressed. The Inspector pointed to a similar gap between a similar pair of angled semi-detached houses elsewhere on the same road. The refusal gave no indication this kind of real, local comparison had been considered.

A National Landscape objection raised informally didn't hold up when tested. The council's officer report - though not part of the formal refusal reason - suggested the scheme would harm the Kent Downs National Landscape by blocking views. The Inspector examined this directly and found no harm to the landscape's silhouette or views, despite it not being challenged in the refusal notice itself.

What this means for other appeals

✓A dismissed appeal isn't necessarily the end. A genuinely redesigned scheme - not just a resubmission of the same design - can succeed where an earlier version failed. Being able to show exactly what changed, and why it addresses the previous decision's reasoning, is the key to a successful second attempt.
✓Check your scheme against the council's own supplementary guidance. Compliance with numeric SPD standards - setbacks, minimum gaps, roof heights - is a strong card to play against a more subjective "cramped" or "out of character" objection.
✓Point to real, comparable examples nearby. A directly comparable gap, extension or feature elsewhere on the same street is more persuasive than an abstract character argument either way.
