Dormer, hip-to-gable and mansard loft conversion drawings for Fareham homes — prepared to Fareham Borough Council's design guidance, delivered in days and revised free until your decision lands, with a free approval-odds score first.
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's roofs set the brief. 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%), and its lofts sit under trussed-rafter roofs typical of 1990s building and trussed-rafter roofs typical of 1980s building — the geometry that decides whether a rear dormer, a hip-to-gable or a mansard gives you the headroom you want. Fareham Borough Council assesses loft proposals against the adopted Fareham local plan and Fareham Borough Council's design guidance for householder work, and its case officers read each roof against the pair next door and the wider street before they read the plans.
That makes drawing quality decisive. We measure ridge and eaves heights, roof pitch and the existing stair, calculate the added volume against the permitted-development limits exactly, and show the workings on the drawings so Fareham Borough Council can verify them. 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 resolve it on the page rather than leave it for the case officer to raise.
Fareham also carries protected 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. We check your address against those designations before a line is drawn.
Many Fareham loft conversions proceed without planning permission — a rear dormer within the permitted-development volume limits (40 cubic metres on a terrace, 50 on a semi or detached house) is usually lawful. You will normally need a full application to Fareham Borough Council if any of these apply:
We draw the roof line, the ridge height and the neighbour's daylight on the page — the relationships Fareham Borough Council's officers check first — and submit a validation-complete pack, whether that is a lawful development certificate or a full householder application.
Below is Fareham Borough Council's real householder decision record, pulled from official planning statistics and updated 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. Professionally prepared loft drawings anticipate those pressure points before submission, which is why complete, policy-literate packs are decided faster and refused less often than DIY applications.

Across Cams Hall, Catisfield and Fareham High Street, the recurring loft is the rear dormer — a box across the back roof slope that turns a cramped attic into a full-height double bedroom and en-suite. On trussed-rafter roofs typical of 1990s building, that is usually the most efficient use of the roof; where the stock is trussed-rafter roofs typical of 1980s building, a hip-to-gable followed by a rear dormer unlocks far more space, though it needs a full application.
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 draw the dormer inside the volume allowance, keep the flat-roof build-up below the ridge, and set the face back from the eaves as the rules require — so the pack answers Fareham Borough Council's questions before they are asked. Where permitted-development rights are exhausted or removed, we prepare a householder application composed to the borough's roof-alteration guidance instead.
We draw loft conversions on every street in the borough. A few of the neighbourhoods where Fareham roofs come up most often:

The right loft in Fareham depends on your roof. This is how the main types compare on planning route and the space they add.
| Loft type | Permitted development? | Space & headroom | What Fareham Borough Council checks |
|---|---|---|---|
| Rear dormer | Usually yes, within volume limits | Full-height double room at the back | Volume, set-back from eaves, ridge height |
| Hip-to-gable | No — full application | Extends the whole side of the roof | Roof bulk and the symmetry of the pair |
| Mansard | No — full application | Maximum floor area across the roof | Street character, especially in conservation areas |
| Rooflights only | Usually yes (Class C) | Light and headroom, no extra footprint | Whether rooflights sit within the existing slope |
Route depends on your street — conservation areas such as Cams Hall and Catisfield and Article 4 directions can remove permitted-development rights.

Tell us your Fareham postcode and roof type. We confirm your conservation and Article 4 status, how much permitted-development volume you have left, and score your odds against live Fareham Borough Council decisions.
We measure ridge and eaves heights, roof pitch, joist levels and the existing stair — the numbers the volume calculation and head heights depend on.
Chartered designers develop the dormer, hip-to-gable or mansard to your brief, drawn inside the Class B limits or to Fareham Borough Council's roof-alteration guidance.
We submit the certificate or application, manage validation and case-officer queries, and revise the drawings free until Fareham Borough Council issues its decision.
Often not. A rear dormer within 40 cubic metres on a terrace, or 50 on a semi-detached or detached house, set back from the eaves and no higher than the ridge, is usually permitted development. In Fareham the main exceptions are hip-to-gable conversions, dormers visible from the highway, and homes in conservation areas such as Cams Hall and Catisfield or on streets with an Article 4 direction. Fareham Borough Council is the decision-maker.
Generally no. In conservation areas including Cams Hall and Catisfield, Class B permitted-development rights for lofts are removed, so a rear dormer that would be lawful elsewhere needs a full application to Fareham Borough Council. Fareham Borough Council has 19 recorded Article 4 directions — check the address before assuming PD applies in the district. We check your exact address before drawing.
On trussed-rafter roofs typical of 1990s building, common across Fareham, a rear dormer is usually the most efficient conversion and often permitted development. Where the roof is trussed-rafter roofs typical of 1980s building, a hip-to-gable followed by a rear dormer gains far more usable space but needs planning permission. Our survey confirms which your roof supports before we draw. Fareham Borough Council is the decision-maker.
A householder planning application in Fareham runs to a statutory eight-week target, and a lawful development certificate to eight weeks as well, though validation can add time if the pack is incomplete. We submit validation-complete drawings and manage case-officer queries to keep the decision on track. Fareham Borough Council is the decision-maker.
If your dormer is permitted development, a lawful development certificate from Fareham Borough Council is council-stamped proof of that — worth having, because every buyer's solicitor will ask for it when you sell. We prepare and submit the certificate application with the same drawing pack.
