Back-of-house extension drawings for Broomhill homes — the glazed kitchen-diner across the rear, drawn to Sheffield City Council's depth and daylight limits, delivered in days and revised free until your decision, with a free approval-odds check first.
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. HMO and flat conversions face concentration limits, amenity, refuse and cycle-storage scrutiny under the Article 4 regime, which is where a policy-literate drawing pack earns its keep. Its dominant Victorian (1837–1901) 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. Broomhill carries at least one Article 4 direction, and conservation areas including Broomhill, Endcliffe and Ranmoor remove those rights outright, so we confirm your exact address before a line is drawn. A validated householder application in Broomhill is determined against an 8-week statutory target.
Broomhill (a wholly urban villa suburb about a mile west of the centre, just north of the Botanical Gardens), Broomhall (Victorian terraces and mansion flats between Broomhill and the city), Crookesmoor (steep terraced streets in the core student-rental belt), Endcliffe (large detached villas edging the Porter valley and Endcliffe Park), Ranmoor (grand stone villas on generous plots up the hill) and Tapton (detached houses and university buildings on the western slope) — these are the Broomhill pockets our drawings cover most. Heritage designations here include Broomhill, Endcliffe, Ranmoor and Northumberland Road. 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 the Broomhill conservation area protects the villa grain, gardens and stone boundary walls against over-development. A large part of Broomhill's villa and terrace stock is now flats and shared houses, none of which hold householder permitted-development rights.. On roofs the borough is gabled slate roofs on the villas and back-addition and terrace roofs shaping side and rear schemes, over large Victorian stone villas around the Botanical Gardens, stone and brick terraces converted to student houses and flats and purpose-built student blocks and mansion flats.
The rear extension is the workhorse of Broomhill home improvement — it is how a dark back kitchen becomes an open family room facing the garden. Because the borough is built largely from large Victorian stone villas around the Botanical Gardens, stone and brick terraces converted to student houses and flats and purpose-built student blocks and mansion flats, most back walls sit close to a neighbour on at least one side, and that proximity, not the design, is what Sheffield City Council scrutinises. The council reads the proposal against the Sheffield Local Plan (the emerging Sheffield Plan, alongside the saved Sheffield Unitary Development Plan and Core Strategy), and the first line an officer draws is the 45-degree splay from the neighbour's nearest window.
So the drawings live or die on geometry. We set the depth against the exact permitted-development figure, hold the eaves and the flat-roof or lantern build-up under the 4-metre height ceiling, and show the projection tested against both the 45-degree plan angle and the 25-degree section angle to the neighbouring windows. HMO and flat conversions face concentration limits, amenity, refuse and cycle-storage scrutiny under the Article 4 regime, so the rear elevation is composed around it rather than corrected after an objection.
Where the property sits in a conservation area — Broomhill, Endcliffe, Ranmoor and Northumberland Road among Broomhill's — the larger-home extension route is switched off and even a modest rear addition needs consent. Broomhill sits at the heart of Sheffield's HMO Article 4 direction (in force since 10 December 2011): converting a family home into a small house in multiple occupation needs planning permission, and applications are normally refused where 20% or more of homes within 200 metres are already HMOs. We confirm the designation before the survey.
Many single-storey rear extensions in Broomhill are permitted development and need no application. You will normally need to apply to Sheffield City Council, or use the larger-home prior-approval route, if any of these apply:
We draw the depth, the roof build-up and the daylight splays to each neighbour on the page — the tests Sheffield City Council's officers apply first — and submit a validation-complete pack, whether that is a lawful development certificate, a larger-home prior-approval notice or a full householder application.
Below is Sheffield City Council's real householder decision record, taken from official planning statistics and refreshed as new data lands. Sheffield grants a high share of householder applications, but Broomhill's Article 4 HMO controls and its villa conservation area make conversion and amenity the recurring pinch points. Rear extensions turn most often on neighbour daylight and depth, so a drawing pack that proves those tests upfront is decided faster and refused less often than a DIY submission.

Across Broomhill, Broomhall and Crookesmoor, the approved rear extension is typically a single-storey glazed box within the depth limit, roofed either flat with a lantern or in a shallow mono-pitch, and finished in brick or render to match the host wall. On the borough's large victorian stone villas around the botanical gardens, keeping the projection to the permitted-development figure often avoids an application entirely; where owners want the full 6 metres, the larger-home route succeeds when the neighbour-consultation period passes without a sustained objection.
The Broomhill conservation area protects the villa grain, gardens and stone boundary walls against over-development. We keep the extension inside the daylight splays, set any glazed roof below the first-floor cill, and retain the garden depth Sheffield City Council expects — so the back elevation answers the amenity case before a neighbour can lodge one. Two-storey rear extensions we draw with the 7-metre boundary gap and privacy screening resolved on the plan.
We draw rear extensions on every street in the borough. A few of the neighbourhoods where Broomhill back-of-house projects come up most often:

How far you can extend at the back in Broomhill depends on your house type and the route you take. This is how the options compare.
| Route | Depth allowed | Consent needed | What Sheffield City Council checks |
|---|---|---|---|
| Standard permitted development | 3m terrace/semi · 4m detached | Lawful development certificate (optional) | Depth, 4m height, materials |
| Larger-home prior approval | 6m terrace/semi · 8m detached | Prior-approval notice + neighbour consultation | Neighbour objections on amenity |
| Full householder application | Beyond the above, or two-storey | Full planning permission | Daylight (45°/25°), bulk, garden retained |
| Conservation area | Case by case | Full planning permission | Character, roof form, boundary treatment |
The larger-home route is switched off on designated land — conservation areas such as Broomhill and Endcliffe and Article 4 streets need a full application.
A fixed process built around how Sheffield City Council validates and decides rear-extension applications — most drawings are submission-ready within seven days of survey.
Send us your Broomhill postcode and house type. We confirm your conservation and Article 4 status, how much rear-extension depth you have under permitted development, and score your odds against live Sheffield City Council decisions.
We measure the original rear wall, floor and eaves levels, side and rear boundary distances and the neighbours' window positions — the numbers the depth limit and daylight splays depend on.
Chartered designers develop the single or two-storey rear extension to your brief, drawn inside the permitted-development limits or to Sheffield City Council's extension design guidance, with the daylight angles shown.
We submit the certificate, prior-approval notice or application, handle validation and case-officer queries, and revise the drawings free until Sheffield City Council issues its decision.
Often not. A single-storey rear extension up to 3 metres deep on a terrace or semi, or 4 metres on a detached house, and no higher than 4 metres, is usually permitted development in Broomhill. You will need to involve Sheffield City Council for anything deeper via the larger-home route, for two-storey rear extensions, and for any rear extension in a conservation area such as Broomhill and Endcliffe, where those permitted-development rights fall away.
The larger-home extension scheme lets a single-storey rear extension reach 6 metres on a terrace or semi, or 8 metres on a detached house — double the standard allowance. It is not automatic: you submit a prior-approval notification to Sheffield City Council, neighbours are consulted, and if one objects on amenity grounds the council rules on it. It also does not apply on designated land such as Broomhill's conservation areas.
It is the daylight test Sheffield City Council applies to protect neighbours. Drawn on plan, a line at 45 degrees from the midpoint of the neighbour's nearest ground-floor window should not be crossed by your extension; a companion 25-degree line is checked in section. If the projection breaches it, the extension is likely to be shortened or refused, so we test and prove it on the drawings before submission. This applies to your Broomhill address specifically.
A two-storey rear extension almost always needs a full householder application to Sheffield City Council, as it sits outside permitted development on most homes. The council checks that it stays at least 7 metres from the rear boundary, does not overbear the neighbours and avoids new overlooking. We resolve the boundary gap, privacy and daylight on the plans so the application is decided on its merits. This applies to your Broomhill address specifically.
Frequently, yes. If the rear extension involves work to a shared wall, building up to the boundary, or excavating foundations near a neighbour's structure, the Party Wall etc. Act applies and you must serve notice — this is separate from Sheffield City Council's planning decision. We flag it early and can prepare the drawings a party-wall surveyor needs alongside the planning set. This applies to your Broomhill address specifically.
