Orangery and conservatory drawings for Tameside homes — checked against the Class A rear limits and the 30m² building-regulations exemption, drawn to Tameside Council's guidance and revised free until your decision.
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 difference is not marketing. A conservatory is predominantly glazed — at least three quarters of the roof and half of the walls — which is what earns it the building-regulations exemption. An orangery has a solid masonry perimeter with a glazed lantern set into a flat roof, so it usually reads as a conventional extension for building control and has to meet Part L thermal standards, Part A structure and Part B fire like any other room.
Both are judged the same way for planning: as rear extensions, against the Class A depth, height and eaves limits, and against Places for Everyone (the Greater Manchester joint plan, effective March 2024) alongside the Tameside Unitary Development Plan. 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, and the design question is usually whether the glazing reads as a lightweight addition to that stock or as a bolted-on conservatory kit. On period houses, an orangery with a properly proportioned lantern almost always sits better than a full-height glazed box.
In conservation areas such as Ashton Town Centre and Stalybridge Town Centre, rear glazing is assessed on visibility from the street and on the effect on the rear elevation's character. 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.
Many conservatories are permitted development. You will need an application to Tameside Council where any of these apply:
We check the scheme against the Class A planning limits and against the building-regulations exemption at the same time, so you know before committing whether you are building an exempt conservatory or a fully regulated room.
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. Glazed rear additions are judged on depth, eaves height and how the glazing meets the existing elevation.

Across Ashton-under-Lyne, Stalybridge and Hyde, the schemes that succeed keep the eaves below the neighbour's ground-floor cill line, set the glazing back from the boundary, and use a solid parapet or brick perimeter to tie the addition into the house. On victorian and edwardian millworkers' terraces in brick, a lantern set in a flat roof usually reads better than a pitched glazed roof, and it avoids the summer overheating that makes full conservatories unusable for months a year.
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. The decision worth making early is whether to keep the separating doors. Keeping them preserves the building-regulations exemption but leaves you with a room that is not part of the house; removing them creates one continuous space but brings the whole addition inside Part L, which changes the glazing specification and usually the heating design too. We set out both versions before you commit.
We draw glazed rear additions across Tameside. A few of the areas where they come up most often:

The planning test is the same for both. The building-regulations test is not.
| Structure | Planning route | Building regulations | Practical effect |
|---|---|---|---|
| Conservatory under 30m², doors retained | Class A rear extension limits | Largely exempt | Cheaper build, unheated in winter |
| Conservatory, doors removed | Class A rear extension limits | Part L applies in full | Continuous space, higher spec glazing |
| Orangery with solid perimeter and lantern | Class A rear extension limits | Fully regulated | Usable year round, better on period houses |
| Any of the above beyond the depth limits | Full householder application | As above | 8-week determination |
| Any of the above on designated land | Full householder application | As above | Design and visibility assessed |
Planning limits from the GPDO 2015, Schedule 2, Part 1, Class A; exemption criteria from the Building Regulations 2010, Schedule 2, Class 7.
A fixed process covering both consents, because they pull in different directions.
Send us your Tameside postcode and house type. We confirm the Class A limits that apply, check designation status, and score your odds against live Tameside Council decisions.
We measure the rear elevation, eaves and ground levels, and the neighbouring boundary — the numbers that decide both the projection limit and the 2-metre eaves rule.
Chartered designers develop the orangery or conservatory to your brief, and we set out clearly whether it stays inside the building-regulations exemption or becomes a fully regulated room.
We submit the certificate or application, manage validation and officer queries, and revise free until Tameside Council decides.
Often not. A conservatory is treated as a rear extension, so it can be permitted development within the Class A limits — 3 metres of projection on a terrace or semi, 4 metres on a detached house, with eaves under 3 metres where it sits within 2 metres of a boundary. In Tameside you will need an application to Tameside Council beyond those limits, and on designated land such as Ashton Town Centre and Stalybridge Town Centre.
A conservatory is largely exempt if it is under 30 square metres, at ground level, separated from the house by external-quality doors, and has at least 75% of its roof and 50% of its walls glazed. Glazing, electrics and any drainage work still have to comply. Remove the separating doors and the exemption falls away — the space becomes part of the house and Part L thermal standards apply. This applies to your Tameside address specifically. Tameside Council is the decision-maker.
For planning, none — both are rear extensions assessed against the same Class A limits by Tameside Council. The difference is in building control: an orangery's solid perimeter and flat roof with a lantern usually means it fails the glazing test for exemption, so it is fully regulated. That is why an orangery costs more to build but is comfortable in January.
Usually yes at the rear, though permitted-development rights are narrower on designated land and an Article 4 direction can remove them entirely. The assessment turns on whether the addition is visible from the street and how it meets the original rear elevation. A restrained orangery in matching brick with a lantern is consistently easier to get through than a proprietary glazed conservatory. This applies to your Tameside address specifically. Tameside Council is the decision-maker.
A fully glazed roof will, unless it is specified for it. That is the practical reason most of our clients end up building an orangery instead: a solid insulated roof perimeter with a lantern gives daylight without the greenhouse effect, and keeps the space usable across the year. We raise it at design stage because it is much cheaper to solve on paper than after the build. This applies to your Tameside address specifically. Tameside Council is the decision-maker.
If you excavate foundations within 3 metres of a neighbouring structure and deeper than its foundations, or build on the boundary itself, the Party Wall etc. Act 1996 applies and notice must be served. That is separate from Tameside Council's planning decision. We flag it at design stage so the notice period does not delay the start on site.
We quote each Tameside orangery or conservatory individually, because the structure and the roof form change the work considerably, and send a fixed, no-obligation quote within one working day.
