Single-storey, double-storey, rear and side extension drawings for Maze Hill homes — measured to Hastings Borough Council's design guidance, delivered in days and revised free until your decision, with a free approval-odds check before you commit.
Hastings Borough Council granted 90% of the householder planning decisions it made in its latest published year — 3 points above the 87% England-wide householder average. Maze Hill contains Burtons', St Leonards, St Leonards West conservation areas, so materials, fenestration and roof form are assessed against the appraisal, which is where a policy-literate drawing pack earns its keep. Its dominant Victorian (1837–1901) and postwar (1945–1970) housing stock sets the design brief on most streets.
Before permission is required, Class B allows 40m³ of added loft volume on a terrace and 50m³ on a semi or detached house, and Class A allows a 3m single-storey rear extension on a terrace or 4m on a detached house. In conservation areas such as Burtons', St Leonards and St Leonards West those rights are removed, so we confirm your exact address before a line is drawn. A validated householder application in Maze Hill is determined against an 8-week statutory target.
Burtons', St Leonards (designated conservation area) and St Leonards West (designated conservation area) — these are the Maze Hill pockets our drawings cover most. Heritage designations here include Burtons', St Leonards and St Leonards West. Hastings Borough Council weighs each proposal against Hastings Borough Council's adopted local plan and its householder design guidance, where the 2,640 homes here are 27% pre-1900, 14% 1983-1992, 13% 1965-1972, which is what sets the realistic roof and rear-projection options. On roofs the borough is steeply pitched slate roofs, valley gutters and party parapets typical of pre-1900 building and trussed-rafter roofs typical of 1980s building, over Victorian and earlier houses (27% of 2,640 homes), 1980s estate houses (14%) and late-1960s and early-1970s houses (13%).
What is permitted in Maze Hill turns on designation first, so that is where we start: Burtons', St Leonards (designated conservation area) and St Leonards West (designated conservation area). Inside those boundaries permitted development is curtailed and Hastings Borough Council assesses materials, window detail and roof form against the area's own appraisal, so a scheme that would be waved through two streets away can need a full application here.
No Article 4 direction is recorded for Hastings Borough Council, but Maze Hill's 2 conservation areas still limit permitted development on those streets.
On stock, Maze Hill is Victorian and earlier houses (27% of 2,640 homes), 1980s estate houses (14%) and late-1960s and early-1970s houses (13%) — which is why steeply pitched slate roofs, valley gutters and party parapets typical of pre-1900 building and trussed-rafter roofs typical of 1980s building govern what a loft or rear projection can realistically be. Hastings Borough Council decided 109 householder applications in the latest published year and granted 90%, with 67% issued inside the eight-week target. We draw to that record rather than to a national average.
The full build-period split for Maze Hill runs pre-1900 27% (700 homes), 1900-1918 5% (140 homes), 1919-1929 1% (20 homes), 1930-1939 10% (260 homes), 1945-1954 1% (30 homes), 1955-1964 7% (180 homes), 1965-1972 13% (340 homes), 1973-1982 9% (250 homes), 1983-1992 14% (360 homes), 1993-1999 5% (140 homes) and 2000-2008 3% (70 homes). That distribution is why pre-1900 detailing dominates the drawings here, and it is measured from council-tax records rather than assumed from the street name.
Hastings Borough Council also decides for Castle, Central St Leonards and Old Hastings, so a decision in Maze Hill sits inside a wider pattern of decisions we track across the same authority — useful when an officer cites a precedent from the next area over.

Maze Hill homes come in a handful of recurring shapes, and each one points to a different extension. The borough is built largely from Victorian and earlier houses (27% of 2,640 homes), 1980s estate houses (14%) and late-1960s and early-1970s houses (13%), 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. Hastings Borough Council judges every one of them against Hastings Borough Council's adopted local plan and its householder design guidance, 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. Maze Hill contains Burtons', St Leonards, St Leonards West conservation areas, so materials, fenestration and roof form are assessed against the appraisal, so we design around it from the first sketch rather than discover it at validation.
Maze Hill also protects whole streets — Burtons', St Leonards and St Leonards West among them. No Article 4 direction is recorded for Hastings Borough Council, but Maze Hill's 2 conservation areas still limit permitted development on those streets. 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 Maze Hill 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 Hastings Borough Council if any of these apply:
We draw the footprint, the ridge and eaves heights and the neighbours' daylight on the page — the relationships Hastings Borough 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 Hastings Borough Council's real householder decision record, drawn from official planning statistics and refreshed as new data lands. Hastings Borough Council granted 90% of its householder applications in the year to 31 March 2026, and Burtons', St Leonards shapes what is approved here. 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 Burtons', St Leonards and St Leonards West, 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 earlier houses (27% of 2,640 homes), a side-return infill frequently pairs with it to square off the plan; on wider late-1960s and early-1970s houses (13%), a two-storey side or rear extension can add a bedroom above without swallowing the garden.
The 2,640 homes here are 27% pre-1900, 14% 1983-1992, 13% 1965-1972, which is what sets the realistic roof and rear-projection options. 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 Hastings Borough 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 Maze Hill projects come up most often:
Extension drawings for Burtons', St Leonards's designated conservation area — footprint-checked, daylight-tested and drawn to Hastings Borough Council's guidance.
Extension drawings for St Leonards West's designated conservation area — footprint-checked, daylight-tested and drawn to Hastings Borough Council's guidance.
The right extension in Maze Hill 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 Hastings Borough 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 Burtons', St Leonards and St Leonards West and Article 4 directions can remove permitted-development rights.
A fixed process built around how Hastings Borough Council validates and decides householder extension applications — most drawings are submission-ready within seven days of survey.
Tell us your Maze Hill 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 Hastings Borough 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 Hastings Borough 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 Hastings Borough 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 Maze Hill you will need to apply to Hastings Borough 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 Burtons', St Leonards and St Leonards 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 Hastings Borough Council and a neighbour-consultation period, and it does not apply on designated land such as Maze Hill'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 Hastings Borough 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 Maze Hill address specifically.
A householder planning application in Maze Hill 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. Hastings Borough 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 Hastings Borough Council's building control or an approved inspector can sign the work off. This applies to your Maze Hill address specifically.
Every house and brief is different, so we price each Maze Hill extension individually and send a fixed, no-obligation quote back within one working day.
