Single-storey, double-storey, rear and side extension drawings for The Avenues 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. Almost the whole district lies within a high tidal-flood-risk zone, so extensions and conversions are expected to raise finished floor levels and add flood resilience, 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.
The permitted-development ceilings are fixed: 40m³ of new roof volume for a terraced loft and 50m³ for a semi or detached house under Class B, plus a 3m single-storey rear extension on a terrace or 4m on a detached house under Class A. The Avenues carries at least one Article 4 direction, and conservation areas including Avenues and Pearson Park, Princes Avenue and Newland remove those rights outright, so we confirm your exact address before a line is drawn. A validated householder application in The Avenues is determined against an 8-week statutory target.
Park Avenue (grandest of the four avenues, wide villas around the restored fountains), Westbourne Avenue (long avenue of gabled Victorian houses inside the conservation area), Marlborough Avenue (red-brick terraces and villas with heavy heritage control), Victoria Avenue (smaller avenue houses close to Princes Avenue), Princes Avenue (commercial and residential frontages in their own conservation area) and Salisbury Street (tight Victorian terraces on the eastern edge of the Avenues) — these are the The Avenues pockets our drawings cover most. Heritage designations here include Avenues and Pearson Park, Princes Avenue and Newland. Hull City Council weighs each proposal against the Hull Local Plan 2016–2032, where the HMO Article 4 direction means sub-division and student conversions are managed tightly against clustering and amenity standards. Many of the large villas have been split into flats and HMOs, and those units carry no householder permitted-development rights.. On roofs the borough is pitched slate roofs with decorative gables on the villas and double-pitched roofs on the terraces, over large late-Victorian villas and terraces off the four tree-lined avenues, Edwardian red-brick terraces and sub-divided houses in multiple occupation.
The Avenues homes come in a handful of recurring shapes, and each one points to a different extension. The borough is built largely from large late-Victorian villas and terraces off the four tree-lined avenues, Edwardian red-brick terraces and sub-divided houses in multiple occupation, 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. Almost the whole district lies within a high tidal-flood-risk zone, so extensions and conversions are expected to raise finished floor levels and add flood resilience, so we design around it from the first sketch rather than discover it at validation.
The Avenues also protects whole streets — Avenues and Pearson Park, Princes Avenue and Newland among them. The Avenues sit inside Hull's houses-in-multiple-occupation Article 4 direction, so converting a family house to a small HMO here needs a full planning application rather than relying on permitted-development rights, and the council refuses new HMOs that would cluster three-in-a-row. 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 The Avenues 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. Hull grants around 91% of the planning applications it decides, but in the Avenues the combined conservation-area and HMO Article 4 controls are the biggest factor shaping what design and use will pass. 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 Park Avenue, Westbourne Avenue and Marlborough Avenue, 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 large late-victorian villas and terraces off the four tree-lined avenues, a side-return infill frequently pairs with it to square off the plan; on wider sub-divided houses in multiple occupation, a two-storey side or rear extension can add a bedroom above without swallowing the garden.
The HMO Article 4 direction means sub-division and student conversions are managed tightly against clustering and amenity standards. 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 The Avenues projects come up most often:

The right extension in The Avenues 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 Avenues and Pearson Park and Princes Avenue 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 The Avenues 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 The Avenues 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 Avenues and Pearson Park and Princes Avenue.
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 The Avenues'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 The Avenues address specifically.
A householder planning application in The Avenues 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 The Avenues address specifically.
Every house and brief is different, so we price each The Avenues extension individually and send a fixed, no-obligation quote back within one working day. It covers the full drawing pack with free revisions until Hull City Council approves, and we tell you upfront whether your extension qualifies as permitted development.
