Two-storey extension drawings for Nether Edge homes — bedroom above, living space below, drawn against the 3-metre projection and 7-metre boundary rules and to Sheffield City Council's design guidance, delivered in days and revised free until your decision.
Sheffield City Council granted 87% of the householder planning decisions it made in its latest published year — level with the 87% England-wide householder average. Conservation-area policy protects the villa building line, boundary walls and mature garden setting that define the district's character, which is where a policy-literate drawing pack earns its keep. Its dominant Victorian (1837–1901) and Edwardian (1901–1910) housing stock sets the design brief on most streets.
Class A and Class B set the thresholds — a rear dormer to 40m³ on a terrace or 50m³ on a semi or detached, and a single-storey rear extension to 3m on a terrace or 4m on a detached house — beyond which Sheffield City Council needs a full application. Nether Edge carries at least one Article 4 direction, and conservation areas including Nether Edge, Norfolk Road and Porter Brook remove those rights outright, so we confirm your exact address before a line is drawn. A validated householder application in Nether Edge is determined against an 8-week statutory target.
Nether Edge (elevated villa streets between the Porter Brook and Sheaf valleys, about two miles south-west of the city centre), Sharrow (dense stone and brick terraces running down towards the city, partly in the HMO Article 4 zone), Brincliffe (substantial detached and semi-detached stone houses on the ridge), Kenwood (grand villas set in mature grounds off Kenwood Road), Machon Bank (Victorian terraces around the local shopping parade) and Highfield (tightly packed inner terraces on the northern edge) — these are the Nether Edge pockets our drawings cover most. Heritage designations here include Nether Edge, Norfolk Road and Porter Brook. Sheffield City Council weighs each proposal against the Sheffield Local Plan (the emerging Sheffield Plan, alongside the saved Sheffield Unitary Development Plan and Core Strategy), where local Yorkshire stone is treated as the prevailing material, so facing stone and slate are expected on visible elevations. Many of the larger Nether Edge and Sharrow villas have been subdivided into flats, which carry no householder permitted-development rights.. On roofs the borough is gabled Welsh-slate roofs on the villas and terraces and hipped roofs on the later semis, over large Victorian and Edwardian villas in Yorkshire stone, stone-built and red-brick terraces and converted flats within the bigger villas.
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. Nether Edge is largely large Victorian and Edwardian villas in Yorkshire stone, stone-built and red-brick terraces and converted flats within the bigger villas, and gabled Welsh-slate roofs on the villas and terraces and hipped roofs on the later semis 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.
Conservation-area policy protects the villa building line, boundary walls and mature garden setting that define the district's character. The Nether Edge conservation area removes permitted-development rights on many of its Victorian villa streets, and the northern Sharrow fringe edges into Sheffield's city-wide HMO Article 4 direction (in force since 10 December 2011), which requires planning permission to convert a family home into a small shared house.
Some two-storey rear extensions are permitted development. You will need a full application to Sheffield City Council if any of these apply:
We set the projection and boundary distance on the site plan, prove the roof-pitch match on the elevations, and specify obscure glazing on the side windows — the three things Sheffield City Council checks first — then submit a validation-complete pack.
Below is Sheffield City Council's real householder decision record, drawn from official planning statistics and refreshed as new data lands. Sheffield grants a high share of householder applications across the city, and in Nether Edge the villa conservation area and its stone-and-slate palette are the constraints that shape most loft and rear schemes. 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.

Across Nether Edge, Sharrow and Brincliffe, 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 large victorian and edwardian villas in yorkshire stone, 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.
Local Yorkshire stone is treated as the prevailing material, so facing stone and slate are expected on visible elevations. 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.
We draw two-storey extensions across Nether Edge. A few of the areas where they come up most often:
Two storey extension drawings for Nether Edge — elevated villa streets between the Porter Brook and Sheaf valleys, about two miles south-west of the city centre — dimensioned against the 3m and 7m limits and drawn to Sheffield City Council's guidance.
Two storey extension drawings for Sharrow — dense stone and brick terraces running down towards the city, partly in the HMO Article 4 zone — dimensioned against the 3m and 7m limits and drawn to Sheffield City Council's guidance.
Two storey extension drawings for Brincliffe — substantial detached and semi-detached stone houses on the ridge — dimensioned against the 3m and 7m limits and drawn to Sheffield City Council's guidance.
Two storey extension drawings for Kenwood — grand villas set in mature grounds off Kenwood Road — dimensioned against the 3m and 7m limits and drawn to Sheffield City Council's guidance.
Two storey extension drawings for Machon Bank — Victorian terraces around the local shopping parade — dimensioned against the 3m and 7m limits and drawn to Sheffield City Council's guidance.
Two storey extension drawings for Highfield — tightly packed inner terraces on the northern edge — dimensioned against the 3m and 7m limits and drawn to Sheffield City Council's guidance.
The first-floor limits are tighter than the ground-floor ones. This is how the common cases compare.
| Scheme | Permitted development? | Deciding limit | What Sheffield City Council checks |
|---|---|---|---|
| Two-storey rear, 3m projection, 7m+ to boundary | Often yes | 3m projection / 7m boundary | Roof match, side-window glazing |
| Two-storey rear, under 7m to boundary | No — full application | Rear-boundary distance | Overlooking, daylight, garden loss |
| Two-storey side extension | No — full application | Side elevation | Gap to boundary, street rhythm |
| Two-storey wraparound | No — full application | Combined footprint | Bulk, massing, neighbour amenity |
| Any two-storey on designated land | No — full application | Designation | Character and appearance |

A fixed process built around how Sheffield City Council validates and decides two-storey applications.
Send us your Nether Edge postcode and garden depth. We measure the 7-metre boundary rule against your plot, confirm designation status, and score your odds against live Sheffield City Council decisions.
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.
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.
We submit the application, manage validation and case-officer queries, and revise the drawings free until Sheffield City Council issues its decision.
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 Nether Edge, the 7-metre rule is what most commonly forces a full application to Sheffield City Council.
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 Nether Edge gardens this is decisive, and we measure it on survey before any design work rather than discovering it at validation. Sheffield City Council is the decision-maker.
Not under permitted development — two-storey side extensions always need a full application to Sheffield City 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 Nether Edge address specifically.
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 Nether Edge address specifically. Sheffield City Council is the decision-maker.
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 Sheffield City Council's planning decision, so we flag the notice period early and detail the junction on the drawings. This applies to your Nether Edge address specifically.
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 Nether Edge address specifically. Sheffield City Council is the decision-maker.
