Where it stands

The council’s file ↗

Conditions attached

The decision notice on the council’s file (published Wed 8 Jul 2026) attaches 1 condition. In the council’s words, each with the reason it gives:

  1. Windows, balconies and privacy
    (a) the materials used in any exterior work (other than materials used in the construction of a conservatory) must be of a similar appearance to those used in the construction of the exterior of the existing dwellinghouse; (b) any upper-floor window located in a wall or roof slope forming a side elevation of the dwellinghouse must be— (i) obscure-glazed, and (ii) non-opening unless the parts of the window which can be opened are more than 1.7 metres above the floor of the room in which the window is installed; and (c) where the enlarged part of the dwellinghouse has more than a single storey, or forms an upper storey on an existing enlargement of the original dwellinghouse, the roof pitch of the enlarged part must, so far as practicable, be the same as the roof pitch of the original dwellinghouse.

    Reason: To ensure that the proposed development falls within the limit of permitted development within Class A of Part 1 of Schedule 2 of The Town and Country Planning (General Permitted Development) (England) Order 2015 (as amended)

We copy the numbered conditions and their reasons and nothing else from the notice; its notes to the applicant are on the file. The label on each is ours, by rules on the council’s wording. The conditions the council attaches, by kind of application

Conservation and heritage on this street

Measured along the street’s line against the council’s boundaries. Whether a particular building is inside depends on where the boundary runs: each area’s page on the council’s site has its map. All 18 conservation areas

The council’s street index lists these properties on The Ridge under Article 4 directions, which take away some building work that wouldn’t otherwise need planning permission:

The council’s Article 4 direction on houses in multiple occupation covers the whole town (in force since 2 July 2012): turning a house into a shared house for three to six people needs planning permission. The council’s page ↗

1 listed building is on or beside The Ridge: the street’s page lists it.

Tree preservation orders within about 40 m of The Ridge’s line, from the council’s map data:

Indicative only — the council’s order is what counts. The council says of its tree order map data: “This dataset is under review and subject to change. Always refer to the Original Tree Preservation Order and associated plan for confirmation.” The council’s tree preservation orders page ↗

Flood zones, the coast and protected nature on this street

We place an application by the street in its address, so these say where The Ridge runs, not where the site’s boundary is. The application’s own documents on the council’s file show the site.

Flood zones

Part of The Ridge is in Flood Zone 3 (rivers). Part of it is in Flood Zone 2 (rivers). That is the Environment Agency’s flood map for planning, which shows land that could flood from rivers or the sea, ignoring the benefits of any existing flood defences.

Locations in flood zone 3 have a high probability of flooding.

This means, in any year, land has:

Flood zone 3 developments need a flood risk assessment as part of their planning application.

Locations in flood zone 2 have a medium probability of flooding.

This means, in any year, land has:

Flood zone 2 developments need a flood risk assessment as part of their planning application.

The Environment Agency’s words, from Flood zones and what they mean ↗.

A street’s line is not an address. For a particular address, use the Environment Agency’s Check your long term flood risk ↗; for a planning site, its Flood map for planning ↗. Flood warnings in force now are on Live now.

Protected nature

Comments on the application

The council’s file counts no comments from the public (as it stood on Thu 15 Oct 2026).

Is a comment public?

The council’s page on commenting says: “All comments will be made available to view online and will be treated in accordance with our privacy policy. Comments will be redacted where they contain personal information or are inappropriate in their content.” It also says: “Please note that we do not accept anonymous comments.” Commenting on an application, on the council’s site ↗ (read 13 October 2026).

We count the comments on the council’s file. We never copy a commenter’s name, address or words, and we don’t list who objected: that is on the file.

If you think work doesn’t match what was approved

The council’s planning enforcement team looks into building work or a use that may not have permission, or may not follow the approved plans or conditions. Its page explains how to report it and which cases it deals with first: planning enforcement on the council’s site ↗

Our planning record starts on 21 April 2026, from the council’s weekly lists of new and decided applications. We list the site, the proposal, the dates, the decision, the comment counts and a permission’s conditions. We never copy a commenter’s or an individual applicant’s details; an applicant is named only when it is an organisation we can match exactly to a council, a registered charity or a company on Companies House. Planning is decided by the council, not by us.
