Single-storey, double-storey, rear and side extension drawings for Fareham homes — measured to Fareham Borough Council's design guidance, delivered in days and revised free until your decision, with a free approval-odds check before you commit.
Fareham Borough Council granted 99% of the householder planning decisions it made in its latest published year — 12 points above the 87% England-wide householder average. Fareham contains Cams Hall, Catisfield, Fareham High Street conservation areas (Cams Hall designated 1982), so materials, fenestration and roof form are assessed against the appraisal, which is where a policy-literate drawing pack earns its keep. Its dominant postwar (1945–1970) 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 Fareham Borough Council needs a full application. Fareham carries at least one Article 4 direction, and conservation areas including Cams Hall, Catisfield and Fareham High Street remove those rights outright, so we confirm your exact address before a line is drawn. A validated householder application in Fareham is determined against an 8-week statutory target.
Cams Hall (conservation area designated in 1982), Catisfield (conservation area designated in 1994), Fareham High Street (conservation area designated in 1969), Hook (conservation area designated in 1974), Osborn Road (conservation area designated in 1979), Sarisbury Green (conservation area designated in 1994), Swanwick Shore (conservation area designated in 1994), Titchfield (conservation area designated in 1969), Fareham Town (ward of Fareham), Hook-with-Warsash (ward of Fareham), Sarisbury & Whiteley (ward of Fareham), Titchfield (ward of Fareham) and Wallington & Downend (ward of Fareham) — these are the Fareham pockets our drawings cover most. Heritage designations here include Cams Hall, Catisfield, Fareham High Street, Hook, Osborn Road, Sarisbury Green, Swanwick Shore and Titchfield. Fareham Borough Council weighs each proposal against the adopted Fareham local plan and Fareham Borough Council's design guidance for householder work, where the 15,840 homes here are 11% 1993-1999, 8% 1983-1992, 8% 1965-1972, which is what sets the realistic roof and rear-projection options. On roofs the borough is trussed-rafter roofs typical of 1990s building and trussed-rafter roofs typical of 1980s building, over 1990s estate houses (11% of 15,840 homes), 1980s estate houses (8%) and late-1960s and early-1970s houses (8%).
Heritage designation is the single biggest variable in Fareham, and it is address-specific: Cams Hall (conservation area designated in 1982), Catisfield (conservation area designated in 1994), Fareham High Street (conservation area designated in 1969), Hook (conservation area designated in 1974), Osborn Road (conservation area designated in 1979), Sarisbury Green (conservation area designated in 1994), Swanwick Shore (conservation area designated in 1994) and Titchfield (conservation area designated in 1969). Inside those boundaries permitted development is curtailed and Fareham 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.
Beyond the designated areas, Fareham takes in Fareham Town, Hook-with-Warsash, Sarisbury & Whiteley, Titchfield and Wallington & Downend. Fareham Borough Council has 19 recorded Article 4 directions — check the address before assuming PD applies in the district.
On stock, Fareham is 1990s estate houses (11% of 15,840 homes), 1980s estate houses (8%) and late-1960s and early-1970s houses (8%) — which is why trussed-rafter roofs typical of 1990s building and trussed-rafter roofs typical of 1980s building govern what a loft or rear projection can realistically be. Fareham Borough Council decided 394 householder applications in the latest published year and granted 99%, with 89% issued inside the eight-week target. We work from the council's own published record.
The full build-period split for Fareham runs pre-1900 3% (190 homes), 1900-1918 0% (30 homes), 1919-1929 0% (10 homes), 1930-1939 6% (350 homes), 1945-1954 3% (170 homes), 1955-1964 30% (1,850 homes), 1965-1972 33% (1,990 homes), 1973-1982 4% (260 homes), 1983-1992 5% (310 homes), 1993-1999 4% (220 homes) and 2000-2008 3% (170 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.
Fareham Borough Council also decides for Fareham Town, Hook-with-Warsash, Sarisbury & Whiteley, Titchfield and Wallington & Downend, so a decision in Fareham 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.
The Article 4 directions recorded for this council include 12-18 Thorney Close, Down End Farm, Hook and Hovercraft. Each removes a specific permitted-development right inside its own boundary, which is why the check is done on the address rather than on the town.

Fareham homes come in a handful of recurring shapes, and each one points to a different extension. The borough is built largely from 1990s estate houses (11% of 15,840 homes), 1980s estate houses (8%) and late-1960s and early-1970s houses (8%), 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. Fareham Borough Council judges every one of them against the adopted Fareham local plan and Fareham Borough Council's design guidance for householder work, 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. Fareham contains Cams Hall, Catisfield, Fareham High Street conservation areas (Cams Hall designated 1982), 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.
Fareham also protects whole streets — Cams Hall, Catisfield, Fareham High Street, Hook, Osborn Road, Sarisbury Green, Swanwick Shore and Titchfield among them. Fareham Borough Council has 19 recorded Article 4 directions — check the address before assuming PD applies in the district. 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 Fareham 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 Fareham 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 Fareham 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 Fareham Borough Council's real householder decision record, drawn from official planning statistics and refreshed as new data lands. Fareham Borough Council granted 99% of 394 householder decisions in the year to 31 March 2026, 89% of them inside eight weeks. 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 Cams Hall, Catisfield and Fareham High 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 1990s estate houses (11% of 15,840 homes), a side-return infill frequently pairs with it to square off the plan; on wider late-1960s and early-1970s houses (8%), a two-storey side or rear extension can add a bedroom above without swallowing the garden.
The 15,840 homes here are 11% 1993-1999, 8% 1983-1992, 8% 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 Fareham 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 Fareham projects come up most often:

The right extension in Fareham 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 Fareham 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 Cams Hall and Catisfield and Article 4 directions can remove permitted-development rights.
A fixed process built around how Fareham Borough Council validates and decides householder extension applications — most drawings are submission-ready within seven days of survey.
Tell us your Fareham 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 Fareham 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 Fareham 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 Fareham 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 Fareham you will need to apply to Fareham 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 Cams Hall and Catisfield.
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 Fareham Borough Council and a neighbour-consultation period, and it does not apply on designated land such as Fareham'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 Fareham 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.
A householder planning application in Fareham 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. Fareham 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 Fareham Borough Council's building control or an approved inspector can sign the work off.
Every house and brief is different, so we price each Fareham extension individually and send a fixed, no-obligation quote back within one working day.
