The fast route to a deep single-storey rear extension in Tameside — up to 6 metres on an attached house or 8 on a detached one — via Tameside Council's prior approval scheme rather than a full planning application.
Tameside Council granted 89% of the householder planning decisions it made in its latest published year — 2 points above the 87% England-wide householder average. The eastern edge around Mottram, Carrbrook and Broadbottom abuts the Peak District National Park and West Pennine moors, triggering heightened landscape-character and rural-setting controls, which is where a policy-literate drawing pack earns its keep. Its dominant Victorian (1837–1901), Edwardian (1901–1910) and interwar (1918–1939) 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. Tameside carries at least one Article 4 direction, and conservation areas including Ashton Town Centre, Stalybridge Town Centre and Mottram in Longdendale remove those rights outright, so we confirm your exact address before a line is drawn. A validated householder application in Tameside is determined against an 8-week statutory target.
Ashton-under-Lyne (principal market and administrative town of Victorian terraces around the Ashton Town Centre conservation area), Stalybridge (mill town on the River Tame with dense terraces and the Copley and Carrbrook stone-village edges), Hyde (industrial town with extensive Victorian terraced streets), Dukinfield (terraced former textile and engineering town adjoining Ashton), Denton (historic hatting town of interwar semis around the St Annes, Haughton conservation area) and Mottram in Longdendale (Pennine-fringe stone-cottage settlement against the Peak District and moors) — these are the Tameside pockets our drawings cover most. Heritage designations here include Ashton Town Centre, Stalybridge Town Centre, Mottram in Longdendale, Copley, Fairfield and St Annes, Haughton. Tameside Council weighs each proposal against Places for Everyone (the Greater Manchester joint plan, effective March 2024) alongside the Tameside Unitary Development Plan, where substantial Green Belt on the eastern and southern fringe, with boundaries revised through Places for Everyone in 2024, limits development on affected plots. Converted terraced flats are common through Ashton, Hyde and Stalybridge, and those units carry no householder permitted-development rights.. On roofs the borough is slate roofs on the Victorian terraces and gritstone stone-flag roofs on the older Pennine-fringe cottages, over Victorian and Edwardian millworkers' terraces in brick, interwar semi-detached houses and gritstone Pennine-fringe cottages and larger detached homes in Longdendale.
The ordinary Class A limits stop a single-storey rear extension at 3 metres on an attached house and 4 on a detached one. The larger home extension scheme doubles both, on condition that the council is told first. That notification is not an application for permission — the council cannot refuse on design, materials or policy grounds. It can only consider the effect on the amenity of adjoining premises, and only if a neighbour actually objects during the 21-day consultation.
The other conditions still apply and are strict: single storey only, no higher than 4 metres, eaves no higher than the existing eaves, and no more than half the land around the original house covered. It is not available on designated land, so a house in a conservation area such as Ashton Town Centre and Stalybridge Town Centre cannot use it at all. Materials must be similar to the existing house, and the extension must not include a veranda, balcony or raised platform.
Tameside is largely Victorian and Edwardian millworkers' terraces in brick, interwar semi-detached houses and gritstone Pennine-fringe cottages and larger detached homes in Longdendale. The eastern edge around Mottram, Carrbrook and Broadbottom abuts the Peak District National Park and West Pennine moors, triggering heightened landscape-character and rural-setting controls, which matters here because an objecting neighbour puts amenity squarely in front of a case officer. Tameside brought in a borough-wide Article 4 direction from October 2025 removing permitted-development rights for the change of use from a house (C3) to a small HMO (C4), and long-standing directions in Mottram in Longdendale and Copley remove certain householder PD rights.
The scheme is available where all of these hold. Fail any one and it is a full application to Tameside Council instead:
We prepare the notification pack Tameside Council needs — plans, elevations, a site plan with the adjoining owners identified — and manage the 21-day neighbour consultation so the 42-day clock is not restarted by an incomplete submission.
Below is Tameside Council's real householder decision record, drawn from official planning statistics and refreshed as new data lands. Tameside approves close to nine in ten planning applications, above the national average, with its Longdendale and Peak District fringe the main brake on what larger schemes can achieve. Prior approval turns on neighbour amenity alone, so the drawings that matter are the ones showing the relationship to the boundary.

Across Ashton-under-Lyne, Stalybridge and Hyde, the notifications that clear without objection are the ones that treat the neighbour as the audience. We show the extension in section against the boundary, demonstrate the 45-degree daylight relationship to the nearest habitable window, and where the plot is tight we taper the depth away from the boundary rather than running the full 6 metres to the fence.
Substantial Green Belt on the eastern and southern fringe, with boundaries revised through Places for Everyone in 2024, limits development on affected plots. Where an objection does arrive, the council's assessment is narrow: loss of light, outlook and overbearing effect on the adjoining property, nothing else. A pack that has already answered those three points on the drawings usually survives an objection, whereas one that leaves them to the officer's imagination usually does not.
We prepare prior-approval notifications across Tameside. A few of the areas where deep rear extensions come up most often:
Prior approval drawings for Ashton-under-Lyne — principal market and administrative town of Victorian terraces around the Ashton Town Centre conservation area — dimensioned to the 6m and 8m limits and prepared for Tameside Council's neighbour consultation.
Prior approval drawings for Stalybridge — mill town on the River Tame with dense terraces and the Copley and Carrbrook stone-village edges — dimensioned to the 6m and 8m limits and prepared for Tameside Council's neighbour consultation.
Prior approval drawings for Hyde — industrial town with extensive Victorian terraced streets — dimensioned to the 6m and 8m limits and prepared for Tameside Council's neighbour consultation.
Prior approval drawings for Dukinfield — terraced former textile and engineering town adjoining Ashton — dimensioned to the 6m and 8m limits and prepared for Tameside Council's neighbour consultation.
Prior approval drawings for Denton — historic hatting town of interwar semis around the St Annes, Haughton conservation area — dimensioned to the 6m and 8m limits and prepared for Tameside Council's neighbour consultation.
Prior approval drawings for Mottram in Longdendale — Pennine-fringe stone-cottage settlement against the Peak District and moors — dimensioned to the 6m and 8m limits and prepared for Tameside Council's neighbour consultation.
Same extension, two routes, very different tests.
| Route | Depth allowed | What the council may consider | Timescale |
|---|---|---|---|
| Ordinary Class A permitted development | 3m attached / 4m detached | Nothing — no application needed | Immediate |
| Larger home extension prior approval | 6m attached / 8m detached | Amenity of adjoining premises, only if a neighbour objects | 21-day consultation, 42-day determination |
| Full householder application | No fixed limit | Design, materials, policy, amenity, everything | 8-week target |
| Any of these on designated land | 3m / 4m only | Prior approval scheme unavailable | Full application beyond the limits |
Limits and procedure from the GPDO 2015, Schedule 2, Part 1, Class A and paragraph A.4, made permanent by amendment in 2019.
A process built around the 21-day consultation, which is where these schemes are won or lost.
Send us your Tameside postcode and house type. We confirm whether the property is on designated land, whether the scheme is available, and what depth you can realistically take.
We measure the original rear wall, eaves height, boundary distances and the neighbouring windows that the amenity assessment will turn on.
We draw the extension to the 6m or 8m limit with the boundary relationship shown in section, and prepare the written description and adjoining-owner details Tameside Council needs to start the consultation.
We submit, track the 21-day consultation and the 42-day determination, respond to any objection on amenity grounds, and revise free until the decision.
Three metres on a terraced or semi-detached house and four on a detached one under ordinary permitted development. Under the larger home extension prior approval scheme those double to six and eight metres, provided you notify Tameside Council before starting and the conditions on height, materials and land coverage are met. The scheme is not available on designated land.
It is a notification, not an application for permission. You tell Tameside Council what you intend to build, it writes to the adjoining owners, and they have 21 days to object. If nobody objects, you may build. If someone does, the council assesses the effect on the amenity of adjoining premises and must decide within 42 days. Design and policy are not in scope.
The council then considers the impact on the amenity of the adjoining property — loss of light, loss of outlook, and overbearing effect — and nothing else. It cannot refuse because it dislikes the design or the materials. We prepare the drawings so those three questions are already answered in section and on the site plan, which is what usually carries an objected scheme through. This applies to your Tameside address specifically. Tameside Council is the decision-maker.
No. The larger home extension scheme is unavailable on designated land, which includes conservation areas such as Ashton Town Centre and Stalybridge Town Centre, national landscapes, national parks and world heritage sites. On those properties the ordinary 3-metre and 4-metre limits apply, and anything deeper needs a full householder application to Tameside Council.
Twenty-one days for the neighbour consultation, and a maximum of 42 days from a valid submission for the council to determine it. If the council does not respond within 42 days you may proceed as notified. That deadline is the scheme's real advantage over a full application, and it is why validation completeness matters so much. This applies to your Tameside address specifically. Tameside Council is the decision-maker.
Yes — always. Prior approval deals only with the planning position. A 6-metre rear extension still needs building control approval for foundations, structure, drainage, thermal performance and fire safety, and the beam over the opening into the existing house needs designing and calculating. We prepare both sets so the notified scheme is the buildable one. This applies to your Tameside address specifically. Tameside Council is the decision-maker.
We quote each Tameside scheme individually, because plot shape and the boundary relationship drive the work, and send a fixed, no-obligation quote within one working day. It covers the notification pack and free revisions until Tameside Council determines it. Call 020 7864 7245 to start.
