Single-storey, double-storey, rear and side extension drawings for Spring Bank homes — measured to Hull City Council's design guidance, delivered in days and revised free until your decision, with a free approval-odds check before you commit.
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 district lies within the citywide high tidal-flood-risk zone, so new floor space is expected to incorporate flood-resilient design, 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. In conservation areas such as Spring Bank, Spring Bank West and Coltman Street those rights are removed, so we confirm your exact address before a line is drawn. A validated householder application in Spring Bank is determined against an 8-week statutory target.
Spring Bank (long radial street of Victorian terraces and shopfronts in a conservation area), Spring Bank West (later terraced housing extending toward the western suburbs), Coltman Street (grand villa terraces in one of Hull's earliest conservation areas), Derringham (interwar suburban housing west of Spring Bank West), Pearson Avenue (compact terraced streets close to the western cemetery) and Boulevard (tree-lined Victorian terraces on the fringe toward Hessle Road) — these are the Spring Bank pockets our drawings cover most. Heritage designations here include Spring Bank, Spring Bank West and Coltman Street. Hull City Council weighs each proposal against the Hull Local Plan 2016–2032, where conversions to flats and shared houses are assessed against amenity, refuse and parking standards even outside the Article 4 area. Numerous Spring Bank terraces have been divided into flats, and those units hold no householder permitted-development rights.. On roofs the borough is pitched slate roofs on the terraces and double-pitched roofs with parapet fronts on the villas, over Victorian and Edwardian terraces off Spring Bank and Spring Bank West, grander villa terraces around Coltman Street and converted terraced flats.
Spring Bank homes come in a handful of recurring shapes, and each one points to a different extension. The borough is built largely from Victorian and Edwardian terraces off Spring Bank and Spring Bank West, grander villa terraces around Coltman Street and converted terraced flats, so a Victorian terrace usually wants a rear or side-return infill, while an interwar semi has room for a wider single-storey wrap or a two-storey side addition. Hull City Council judges every one of them against the Hull Local Plan 2016–2032, weighing footprint, height and the impact on the house next door before it looks at the elevations.
That is why the drawings decide the outcome. We set the extension depth against the permitted-development limits precisely, keep the eaves and ridge within the allowances, and plot the 45-degree daylight lines to the neighbours' windows so the case officer can see the amenity test is passed. The district lies within the citywide high tidal-flood-risk zone, so new floor space is expected to incorporate flood-resilient design, so we design around it from the first sketch rather than discover it at validation.
Spring Bank also protects whole streets — Spring Bank, Spring Bank West and Coltman Street among them. Spring Bank falls outside the boundary of Hull's HMO Article 4 direction, which is centred on the Avenues and Newland, but its conservation areas still remove some permitted-development rights and shape what alterations to the terraces are acceptable. On designated land the larger-home extension route and most side extensions stop being permitted development, so we confirm your address against those layers before drawing a line.
Plenty of Spring Bank extensions are permitted development and need no planning application — a single-storey rear extension within the depth and height limits is the common case. You will normally need to apply to Hull City Council if any of these apply:
We draw the footprint, the ridge and eaves heights and the neighbours' daylight on the page — the relationships Hull City Council's officers weigh first — and submit a validation-complete pack, whether that is a lawful development certificate, a prior-approval notification or a full householder application.
Below is Hull City Council's real householder decision record, drawn from official planning statistics and refreshed as new data lands. Against Hull's overall approval rate of roughly 91%, Spring Bank schemes turn most on conservation-area character and the quality of any conversion rather than on use controls. A complete, policy-literate extension pack anticipates those pressure points before submission, which is why professionally drawn applications are decided faster and refused less often than DIY ones.

Across Spring Bank, Spring Bank West and Coltman Street, the extension that lands most often is the single-storey rear addition — a glazed kitchen-diner across the back of the house, kept within the permitted-development depth or taken to a full application where the ground floor wants more. On the borough's victorian and edwardian terraces off spring bank and spring bank west, a side-return infill frequently pairs with it to square off the plan; on wider converted terraced flats, a two-storey side or rear extension can add a bedroom above without swallowing the garden.
Conversions to flats and shared houses are assessed against amenity, refuse and parking standards even outside the Article 4 area. We size the extension to the amenity and daylight tests, match the roof and materials to the host house, and keep enough garden to satisfy Hull City Council's space standards — so the scheme answers the borough's questions before an objection can raise them. Where permitted-development rights are used up or removed, we prepare the householder application to the council's extension design guidance instead.
We draw extensions on every street in the borough. A few of the neighbourhoods where Spring Bank projects come up most often:

The right extension in Spring Bank depends on your house type and how much garden you can give up. This is how the main options compare on planning route and what they add.
| Extension type | Permitted development? | What it adds | What Hull City Council checks |
|---|---|---|---|
| Single-storey rear | Often, within 3m/4m depth (6m/8m via prior approval) | Bigger kitchen-diner across the back | Depth, height, neighbour daylight (45°) |
| Side-return infill | Sometimes, if within width and height limits | Squares off an L-shaped ground floor | Width vs the original house, glazing to boundary |
| Two-storey rear/side | No — full application | Extra bedroom or bathroom above | Bulk, overlooking, 7m rear-boundary gap |
| Wraparound (rear + side) | No — full application | Whole-width open-plan ground floor | Combined footprint and garden retained |
Route depends on your street — conservation areas such as Spring Bank and Spring Bank West and Article 4 directions can remove permitted-development rights.
A fixed process built around how Hull City Council validates and decides householder extension applications — most drawings are submission-ready within seven days of survey.
Tell us your Spring Bank postcode and house type. We confirm your conservation and Article 4 status, how much permitted-development depth you have left, and score your odds against live Hull City Council decisions.
We measure the existing footprint, floor and eaves levels, boundary distances and the neighbours' window positions — the numbers the depth limits and daylight tests depend on.
Chartered designers develop the single-storey, two-storey or side extension to your brief, drawn inside the permitted-development limits or to Hull City Council's extension design guidance.
We submit the certificate, prior-approval notice or application, manage validation and case-officer queries, and revise the drawings free until Hull City Council issues its decision.
Not always. 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 Spring Bank you will need to apply to Hull City Council for two-storey extensions, side extensions wider than half the house, anything forward of the front wall, deeper rear extensions under the larger-home prior-approval route, and any extension in a conservation area such as Spring Bank and Spring Bank West.
Standard permitted development allows 3 metres on a terraced or semi-detached house and 4 metres on a detached one. The larger-home extension scheme can double that to 6 or 8 metres, but it needs a prior-approval notification to Hull City Council and a neighbour-consultation period, and it does not apply on designated land such as Spring Bank's conservation areas. We confirm which route your property qualifies for before drawing.
Two-storey and double-storey extensions almost always need a full householder application to Hull City Council, because they fall outside permitted development on most homes. The council looks closely at bulk, overlooking of neighbours and the 7-metre gap a two-storey rear extension must keep from the rear boundary. We design to those tests and show the daylight and privacy angles on the drawings. This applies to your Spring Bank address specifically.
A householder planning application in Spring Bank runs to a statutory eight-week target, a larger-home prior-approval notification to around six weeks including the neighbour-consultation period, and a lawful development certificate to eight weeks. Incomplete submissions stall at validation, so we submit a complete pack and manage officer queries to keep the decision on schedule. Hull City Council is the decision-maker.
Yes — planning permission and building regulations are separate consents, and almost every extension needs both. Planning governs whether you can build it; building control governs how it is built, covering structure, insulation, drainage and fire safety. We prepare the building-regulations drawings alongside the planning set so Hull City Council's building control or an approved inspector can sign the work off. This applies to your Spring Bank address specifically.
Every house and brief is different, so we price each Spring Bank extension individually and send a fixed, no-obligation quote back within one working day.
