Single-storey, double-storey, rear and side extension drawings for Burgess Hill Victoria homes — measured to Mid Sussex District Council's design guidance, delivered in days and revised free until your decision, with a free approval-odds check before you commit.
Mid Sussex District Council granted 93% of the householder planning decisions it made in its latest published year — 6 points above the 87% England-wide householder average. Burgess Hill Victoria contains the Fairfield conservation area (Fairfield designated 1989), 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 Fairfield those rights are removed, so we confirm your exact address before a line is drawn. A validated householder application in Burgess Hill Victoria is determined against an 8-week statutory target.
Fairfield (conservation area designated in 1989) and Burgess Hill (civil parish within Burgess Hill Victoria) — these are the Burgess Hill Victoria pockets our drawings cover most. Heritage designations here include Fairfield. Mid Sussex District Council weighs each proposal against Mid Sussex District Council's development plan and the design policies it applies to householder applications, where the 1,840 homes here are 23% 1955-1964, 18% pre-1900, 10% 1945-1954, which is what sets the realistic roof and rear-projection options. On roofs the borough is shallow gabled roofs typical of that period's building and steeply pitched slate roofs, valley gutters and party parapets typical of pre-1900 building, over late-1950s and early-1960s houses (23% of 1,840 homes), Victorian and earlier houses (18%) and early postwar houses (10%).
What is permitted in Burgess Hill Victoria turns on designation first, so that is where we start: Fairfield (conservation area designated in 1989). Inside those boundaries permitted development is curtailed and Mid Sussex District 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.
Beyond the designated areas, Burgess Hill Victoria takes in Burgess Hill. No Article 4 direction is recorded for Mid Sussex District Council, but Burgess Hill Victoria's 1 conservation area still limit permitted development on those streets.
On stock, Burgess Hill Victoria is late-1950s and early-1960s houses (23% of 1,840 homes), Victorian and earlier houses (18%) and early postwar houses (10%) — which is why shallow gabled roofs typical of that period's building and steeply pitched slate roofs, valley gutters and party parapets typical of pre-1900 building govern what a loft or rear projection can realistically be. Mid Sussex District Council decided 697 householder applications in the latest published year and granted 93%, with 64% issued inside the eight-week target. We draw to that record rather than to a national average.
The full build-period split for Burgess Hill Victoria runs pre-1900 18% (330 homes), 1900-1918 3% (50 homes), 1919-1929 6% (110 homes), 1930-1939 4% (80 homes), 1945-1954 10% (180 homes), 1955-1964 23% (420 homes), 1965-1972 10% (180 homes), 1973-1982 4% (70 homes), 1983-1992 1% (10 homes), 1993-1999 2% (30 homes) and 2000-2008 4% (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.
Mid Sussex District Council also decides for Downland Villages, Haywards Heath North, Hurstpierpoint and Lindfield, so a decision in Burgess Hill Victoria 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.

Burgess Hill Victoria homes come in a handful of recurring shapes, and each one points to a different extension. The borough is built largely from late-1950s and early-1960s houses (23% of 1,840 homes), Victorian and earlier houses (18%) and early postwar houses (10%), 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. Mid Sussex District Council judges every one of them against Mid Sussex District Council's development plan and the design policies it applies to householder applications, 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. Burgess Hill Victoria contains the Fairfield conservation area (Fairfield designated 1989), 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.
Burgess Hill Victoria also protects whole streets — Fairfield among them. No Article 4 direction is recorded for Mid Sussex District Council, but Burgess Hill Victoria's 1 conservation area 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 Burgess Hill Victoria 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 Mid Sussex District Council if any of these apply:
We draw the footprint, the ridge and eaves heights and the neighbours' daylight on the page — the relationships Mid Sussex District 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 Mid Sussex District Council's real householder decision record, drawn from official planning statistics and refreshed as new data lands. Mid Sussex District Council granted 93% of its householder applications in the year to 31 March 2026, and Fairfield 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 Fairfield and Burgess Hill, 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 late-1950s and early-1960s houses (23% of 1,840 homes), a side-return infill frequently pairs with it to square off the plan; on wider early postwar houses (10%), a two-storey side or rear extension can add a bedroom above without swallowing the garden.
The 1,840 homes here are 23% 1955-1964, 18% pre-1900, 10% 1945-1954, 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 Mid Sussex District 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 Burgess Hill Victoria projects come up most often:
Extension drawings for Fairfield's conservation area designated in 1989 — footprint-checked, daylight-tested and drawn to Mid Sussex District Council's guidance.

The right extension in Burgess Hill Victoria 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 Mid Sussex District 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 Fairfield and Article 4 directions can remove permitted-development rights.
A fixed process built around how Mid Sussex District Council validates and decides householder extension applications — most drawings are submission-ready within seven days of survey.
Tell us your Burgess Hill Victoria 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 Mid Sussex District 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 Mid Sussex District 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 Mid Sussex District 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 Burgess Hill Victoria you will need to apply to Mid Sussex District 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 Fairfield.
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 Mid Sussex District Council and a neighbour-consultation period, and it does not apply on designated land such as Burgess Hill Victoria'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 Mid Sussex District 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 Burgess Hill Victoria address specifically.
A householder planning application in Burgess Hill Victoria 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. Mid Sussex District 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 Mid Sussex District Council's building control or an approved inspector can sign the work off. This applies to your Burgess Hill Victoria address specifically.
