Ambien householder planning by the numbers

Hinckley and Bosworth Borough Council granted 94% of the householder planning decisions it made in its latest published year — 7 points above the 87% England-wide householder average. Ambien contains Ashby-de-la-Zouch Canal, Higham on the Hill, Shenton conservation areas (Ashby-de-la-Zouch Canal designated 1990), so materials, fenestration and roof form are assessed against the appraisal, which is where a policy-literate drawing pack earns its keep. Its dominant Victorian (1837–1901) and postwar (1945–1970) housing stock sets the design brief on most streets.

Under Class B, a rear dormer stays permitted development up to 40m³ of added roof volume on a terrace or 50m³ on a semi-detached or detached house, while Class A allows a single-storey rear extension of 3m beyond the original rear wall on a terrace and 4m on a detached house before a full application is needed. In conservation areas such as Ashby-de-la-Zouch Canal, Higham on the Hill and Shenton those rights are removed, so we confirm your exact address before a line is drawn. A validated householder application in Ambien is determined against an 8-week statutory target.

Ashby-de-la-Zouch Canal (conservation area designated in 1990), Higham on the Hill (conservation area designated in 1995), Shenton (designated conservation area), Sibson (designated conservation area), Stoke Golding (conservation area designated in 2004), Sutton Cheney (designated conservation area), Higham on the Hill (civil parish within Ambien), Sheepy (civil parish within Ambien), Stoke Golding (civil parish within Ambien) and Dadlington & Sutton Cheney (civil parish within Ambien) — these are the Ambien pockets our drawings cover most. Heritage designations here include Ashby-de-la-Zouch Canal, Higham on the Hill, Shenton, Sibson, Stoke Golding and Sutton Cheney. Hinckley and Bosworth Borough Council weighs each proposal against Hinckley and Bosworth Borough Council's development plan and the design policies it applies to householder applications, where the 1,760 homes here are 15% pre-1900, 12% 1955-1964, 12% 1965-1972, which is what sets the realistic roof and rear-projection options. On roofs the borough is steeply pitched slate roofs, valley gutters and party parapets typical of pre-1900 building and shallow gabled roofs typical of that period's building, over Victorian and earlier houses (15% of 1,760 homes), late-1950s and early-1960s houses (12%) and late-1960s and early-1970s houses (12%).

What actually constrains a project in Ambien

Ambien's designated heritage is specific, and it is the first thing we check against your address: Ashby-de-la-Zouch Canal (conservation area designated in 1990), Higham on the Hill (conservation area designated in 1995), Shenton (designated conservation area), Sibson (designated conservation area), Stoke Golding (conservation area designated in 2004) and Sutton Cheney (designated conservation area). Inside those boundaries permitted development is curtailed and Hinckley and Bosworth Borough Council assesses materials, window detail and roof form against the area's own appraisal, so a scheme that would be waved through two streets away can need a full application here.

Beyond the designated areas, Ambien takes in Higham on the Hill, Sheepy, Stoke Golding and Dadlington & Sutton Cheney. No Article 4 direction is recorded for Hinckley and Bosworth Borough Council, but Ambien's 6 conservation areas still limit permitted development on those streets.

On stock, Ambien is Victorian and earlier houses (15% of 1,760 homes), late-1950s and early-1960s houses (12%) and late-1960s and early-1970s houses (12%) — which is why steeply pitched slate roofs, valley gutters and party parapets typical of pre-1900 building and shallow gabled roofs typical of that period's building govern what a loft or rear projection can realistically be. Hinckley and Bosworth Borough Council decided 282 householder applications in the latest published year and granted 94%, with 37% issued inside the eight-week target. Those are the numbers our drawings are prepared against.

The full build-period split for Ambien runs pre-1900 15% (270 homes), 1900-1918 2% (40 homes), 1919-1929 5% (80 homes), 1930-1939 4% (70 homes), 1945-1954 6% (100 homes), 1955-1964 12% (220 homes), 1965-1972 12% (210 homes), 1973-1982 5% (80 homes), 1983-1992 8% (140 homes), 1993-1999 3% (60 homes) and 2000-2008 4% (70 homes). That distribution is why pre-1900 detailing dominates the drawings here, and it is measured from council-tax records rather than assumed from the street name.

Hinckley and Bosworth Borough Council also decides for Barwell and Hinckley Castle, so a decision in Ambien sits inside a wider pattern of decisions we track across the same authority — useful when an officer cites a precedent from the next area over.

The three tests a Ambien two-storey extension has to pass

Adding at first floor changes the question the case officer asks. A single-storey extension is judged mostly on daylight and garden loss; a two-storey extension is judged on overlooking, bulk against the neighbouring roofline, and whether it reads as part of the house or bolted onto it. Ambien is largely Victorian and earlier houses (15% of 1,760 homes), late-1950s and early-1960s houses (12%) and late-1960s and early-1970s houses (12%), and steeply pitched slate roofs, valley gutters and party parapets typical of pre-1900 building and shallow gabled roofs typical of that period's building set what a matching roof actually means here.

The permitted-development route exists but is narrow: 3 metres of rear projection, a 7-metre stand-off from the rear boundary, eaves and ridge no higher than the original, and side-facing upper windows obscure-glazed and non-opening below 1.7 metres above floor level. Most two-storey schemes fail one of those, usually the 7-metre boundary rule on a shorter garden, and go in as a full application instead. We establish which route applies before designing, because it changes the drawing set.

Ambien contains Ashby-de-la-Zouch Canal, Higham on the Hill, Shenton conservation areas (Ashby-de-la-Zouch Canal designated 1990), so materials, fenestration and roof form are assessed against the appraisal. No Article 4 direction is recorded for Hinckley and Bosworth Borough Council, but Ambien's 6 conservation areas still limit permitted development on those streets.

Does a two storey extension need planning permission in Ambien?

Some two-storey rear extensions are permitted development. You will need a full application to Hinckley and Bosworth Borough Council if any of these apply:

  • The extension projects more than 3 metres beyond the original rear wall
  • Any part comes within 7 metres of the rear boundary
  • The eaves or ridge would sit higher than the existing house
  • The extension is to the side, or wraps around to the side at first floor
  • Upper-floor side windows are clear-glazed or open below 1.7 metres
  • The property is on designated land such as Ashby-de-la-Zouch Canal and Higham on the Hill, where two-storey rights are removed

Ambien two-storey extension approval rates — live council data

Below is Hinckley and Bosworth Borough Council's real householder decision record, drawn from official planning statistics and refreshed as new data lands. Hinckley and Bosworth Borough Council granted 94% of its householder applications in the year to 31 March 2026, and Ashby-de-la-Zouch Canal shapes what is approved here. Two-storey schemes attract more neighbour comment than any other householder work, so the overlooking and daylight case has to be made on the drawings.

What two-storey extensions get approved in Ambien

Across Ashby-de-la-Zouch Canal, Higham on the Hill and Shenton, the schemes that succeed set the first floor back from the ground floor, keep the ridge below the original, and treat the flank wall as blank or obscure-glazed. On victorian and earlier houses (15% of 1,760 homes), matching the eaves line matters more than matching the brick: an extension that carries the existing eaves through reads as original even in a different material.

The 1,760 homes here are 15% pre-1900, 12% 1955-1964, 12% 1965-1972, which is what sets the realistic roof and rear-projection options. We draw the 45-degree daylight test from the neighbour's nearest habitable window, show the window positions in section, and set out the steel and foundation implications early — a two-storey extension changes the load path, so the structural design and the planning design have to be developed together rather than in sequence.

Four steps to an approved Ambien two-storey extension

A fixed process built around how Hinckley and Bosworth Borough Council validates and decides two-storey applications.

  1. 1

    Free approval check

    Send us your Ambien postcode and garden depth. We measure the 7-metre boundary rule against your plot, confirm designation status, and score your odds against live Hinckley and Bosworth Borough Council decisions.

  2. 2

    Measured survey

    We measure the original rear wall, eaves and ridge heights, garden depth and every neighbouring window that faces the site — the inputs the daylight and overlooking case is built from.

  3. 3

    Design, drawings & structure

    Chartered designers develop the two-storey addition to your brief with the roof and eaves resolved, and we coordinate the load path so the structural scheme and the planning scheme are the same building.

  4. 4

    Submission & follow-through

    We submit the application, manage validation and case-officer queries, and revise the drawings free until Hinckley and Bosworth Borough Council issues its decision.

Frequently asked questions

Do I need planning permission for a two storey extension in Ambien?

Often, but not always. A two-storey rear extension can be permitted development if it projects no more than 3 metres, sits at least 7 metres from the rear boundary, does not exceed the existing eaves and ridge, and has obscure-glazed non-opening side windows below 1.7 metres. In Ambien, the 7-metre rule is what most commonly forces a full application to Hinckley and Bosworth Borough Council.

What is the 7 metre rule for two storey extensions in Ambien?

No part of a permitted-development two-storey rear extension may come within 7 metres of the boundary opposite the rear wall of the house. It exists to protect the neighbour behind you from being overlooked at first floor. On shorter Ambien gardens this is decisive, and we measure it on survey before any design work rather than discovering it at validation. Hinckley and Bosworth Borough Council is the decision-maker.

Can I build a two storey side extension in Ambien?

Not under permitted development — two-storey side extensions always need a full application to Hinckley and Bosworth Borough Council. They are assessed on the gap to the boundary, whether the street's rhythm of spaces between houses survives, and whether the extension is subordinate to the original. Setting the first floor back from the front building line and down from the ridge is what usually makes the difference. This applies to your Ambien address specifically.

Will a two storey extension in Ambien be refused for overlooking?

Overlooking is the most common objection, and it is answerable on the drawings. We position habitable-room windows away from neighbouring gardens, obscure-glaze and fix shut anything on the flank below 1.7 metres, and show the sight lines in section. Where the geometry is tight, a rooflight or a high-level window gives the same daylight without the mutual overlooking that draws objections. This applies to your Ambien address specifically. Hinckley and Bosworth Borough Council is the decision-maker.

Do I need a party wall agreement for a two storey extension in Ambien?

Almost certainly. Excavating within 3 metres of a neighbouring structure and building on or up to the boundary both trigger the Party Wall etc. Act 1996, and a two-storey extension usually does both. It is entirely separate from Hinckley and Bosworth Borough Council's planning decision, so we flag the notice period early and detail the junction on the drawings. This applies to your Ambien address specifically.

Does a two storey extension need structural calculations in Ambien?

Yes. Adding a floor changes the load path from roof to foundation, so beams, padstones and foundation depths all need designing and calculating for building control. Planning and building regulations are separate consents, and the structural set is what building control assesses — we prepare both so the approved scheme is the buildable one. This applies to your Ambien address specifically. Hinckley and Bosworth Borough Council is the decision-maker.

How much do two storey extension plans in Ambien cost?

We quote each Ambien two-storey extension individually, because plot depth, roof form and structural complexity vary house to house, and send a fixed, no-obligation quote within one working day. It covers the drawing pack with free revisions until Hinckley and Bosworth Borough Council approves. Call 020 7864 7245 to start.
