Back-of-house extension drawings for Old Town, Hull homes — the glazed kitchen-diner across the rear, drawn to Hull City Council's depth and daylight limits, delivered in days and revised free until your decision, with a free approval-odds check first.
Hull City Council granted 91% of the householder planning decisions it made in its latest published year — 4 points above the 87% England-wide householder average. The Old Town sits behind the Humber's tidal defences in a high flood-risk zone, so conversions of historic and warehouse buildings must demonstrate flood resilience and safe access, which is where a policy-literate drawing pack earns its keep. Its dominant Georgian (1714–1837) and 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 Hull City Council needs a full application. In conservation areas such as Old Town, Georgian New Town and Charterhouse those rights are removed, so we confirm your exact address before a line is drawn. A validated householder application in Old Town, Hull is determined against an 8-week statutory target.
High Street (medieval merchant lane with staithes and listed warehouses along the River Hull), Fruit Market (regenerated warehouse quarter of apartments and studios by the marina), Land of Green Ginger (narrow historic street of Georgian frontages in the Old Town core), Charterhouse (almshouse precinct and terraces in their own conservation area north of the centre), Georgian New Town (planned late-Georgian streets around Charlotte Street and Kingston Square) and Wincolmlee (former industrial riverside with warehouse and mill conversions) — these are the Old Town, Hull pockets our drawings cover most. Heritage designations here include Old Town, Georgian New Town, Charterhouse and Wincolmlee. Hull City Council weighs each proposal against the Hull Local Plan 2016–2032, where listed-building density means most works need listed-building consent alongside planning permission, and pastiche or over-glazed additions are resisted. Much of the Old Town and Fruit Market is flatted through warehouse and merchant-house conversion, so householder permitted-development rights rarely apply.. On roofs the borough is pitched and mansard roofs on the historic buildings and flat and parapet-hidden roofs on warehouse conversions, over Georgian and Victorian merchant houses and warehouses, converted riverside and staith-side buildings and modern apartment infill in the Fruit Market.
The rear extension is the workhorse of Old Town, Hull home improvement — it is how a dark back kitchen becomes an open family room facing the garden. Because the borough is built largely from Georgian and Victorian merchant houses and warehouses, converted riverside and staith-side buildings and modern apartment infill in the Fruit Market, most back walls sit close to a neighbour on at least one side, and that proximity, not the design, is what Hull City Council scrutinises. The council reads the proposal against the Hull Local Plan 2016–2032, 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. The Old Town sits behind the Humber's tidal defences in a high flood-risk zone, so conversions of historic and warehouse buildings must demonstrate flood resilience and safe access, so the rear elevation is composed around it rather than corrected after an objection.
Where the property sits in a conservation area — Old Town, Georgian New Town, Charterhouse and Wincolmlee among Old Town, Hull's — the larger-home extension route is switched off and even a modest rear addition needs consent. The Old Town is not covered by Hull's HMO Article 4 direction, which is focused on the university quarter, but as one of the city's most sensitive conservation areas almost every external alteration here needs consent regardless of permitted-development rights. We confirm the designation before the survey.

Many single-storey rear extensions in Old Town, Hull are permitted development and need no application. You will normally need to apply to Hull 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 Hull 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 Hull City Council's real householder decision record, taken from official planning statistics and refreshed as new data lands. Hull grants about 91% of its decisions, but in the Old Town the exceptional heritage sensitivity and listed-building controls are the constraint that governs design far more than the headline rate. 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 High Street, Fruit Market and Land of Green Ginger, 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 georgian and victorian merchant houses and warehouses, 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.
Listed-building density means most works need listed-building consent alongside planning permission, and pastiche or over-glazed additions are resisted. We keep the extension inside the daylight splays, set any glazed roof below the first-floor cill, and retain the garden depth Hull 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 Old Town, Hull back-of-house projects come up most often:

How far you can extend at the back in Old Town, Hull depends on your house type and the route you take. This is how the options compare.
| Route | Depth allowed | Consent needed | What Hull 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 Old Town and Georgian New Town and Article 4 streets need a full application.
A fixed process built around how Hull City Council validates and decides rear-extension applications — most drawings are submission-ready within seven days of survey.
Send us your Old Town, Hull 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 Hull 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 Hull 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 Hull 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 Old Town, Hull. You will need to involve Hull 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 Old Town and Georgian New Town, 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 Hull 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 Old Town, Hull's conservation areas.
It is the daylight test Hull 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 Old Town, Hull address specifically.
A two-storey rear extension almost always needs a full householder application to Hull 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 Old Town, Hull 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 Hull 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 Old Town, Hull address specifically.
