Dormer, hip-to-gable and mansard loft conversion drawings for The Witterings homes — prepared to Chichester District Council's design guidance, delivered in days and revised free until your decision lands, with a free approval-odds score first.
Chichester District Council granted 95% of the householder planning decisions it made in its latest published year — 8 points above the 87% England-wide householder average. The Witterings contains Earnley, Somerley, West Itchenor conservation areas (Earnley designated 1976), so materials, fenestration and roof form are assessed against the appraisal, which is where a policy-literate drawing pack earns its keep. Its dominant interwar (1918–1939) and postwar (1945–1970) housing stock sets the design brief on most streets.
Under Class B, a rear dormer stays permitted development up to 40m³ of added roof volume on a terrace or 50m³ on a semi-detached or detached house, while Class A allows a single-storey rear extension of 3m beyond the original rear wall on a terrace and 4m on a detached house before a full application is needed. In conservation areas such as Earnley, Somerley and West Itchenor those rights are removed, so we confirm your exact address before a line is drawn. A validated householder application in The Witterings is determined against an 8-week statutory target.
Earnley (conservation area designated in 1976), Somerley (conservation area designated in 1976), West Itchenor (conservation area designated in 1976), West Wittering (conservation area designated in 1976), Birdham (civil parish within The Witterings), Earnley (civil parish within The Witterings), East Wittering (civil parish within The Witterings), West Itchenor (civil parish within The Witterings) and West Wittering (civil parish within The Witterings) — these are the The Witterings pockets our drawings cover most. Heritage designations here include Earnley, Somerley, West Itchenor and West Wittering. Chichester District Council weighs each proposal against Chichester District Council's adopted local plan and its householder design guidance, where the 5,900 homes here are 13% 1973-1982, 13% 1955-1964, 13% 1930-1939, which is what sets the realistic roof and rear-projection options. On roofs the borough is shallow trussed roofs typical of 1970s building and shallow gabled roofs typical of that period's building, over 1970s and early-1980s houses (13% of 5,900 homes), late-1950s and early-1960s houses (13%) and 1930s semi-detached and detached houses (13%).
The Witterings's designated heritage is specific, and it is the first thing we check against your address: Earnley (conservation area designated in 1976), Somerley (conservation area designated in 1976), West Itchenor (conservation area designated in 1976) and West Wittering (conservation area designated in 1976). Inside those boundaries permitted development is curtailed and Chichester 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, The Witterings takes in Birdham, Earnley, East Wittering, West Itchenor and West Wittering. No Article 4 direction is recorded for Chichester District Council, but The Witterings's 4 conservation areas still limit permitted development on those streets.
On stock, The Witterings is 1970s and early-1980s houses (13% of 5,900 homes), late-1950s and early-1960s houses (13%) and 1930s semi-detached and detached houses (13%) — which is why shallow trussed roofs typical of 1970s building and shallow gabled roofs typical of that period's building govern what a loft or rear projection can realistically be. Chichester District Council decided 470 householder applications in the latest published year and granted 95%, with 93% issued inside the eight-week target. Those are the numbers our drawings are prepared against.
The full build-period split for The Witterings runs pre-1900 4% (260 homes), 1900-1918 0% (20 homes), 1919-1929 2% (100 homes), 1930-1939 13% (740 homes), 1945-1954 4% (220 homes), 1955-1964 13% (760 homes), 1965-1972 11% (640 homes), 1973-1982 13% (790 homes), 1983-1992 8% (500 homes), 1993-1999 8% (460 homes) and 2000-2008 9% (530 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.
Chichester District Council also decides for Chichester North, Fernhurst, Goodwood, Harbour Villages, Loxwood, Southbourne and Westbourne, so a decision in The Witterings 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 Witterings's roofs set the brief. The borough is built largely from 1970s and early-1980s houses (13% of 5,900 homes), late-1950s and early-1960s houses (13%) and 1930s semi-detached and detached houses (13%), and its lofts sit under shallow trussed roofs typical of 1970s building and shallow gabled roofs typical of that period's building — the geometry that decides whether a rear dormer, a hip-to-gable or a mansard gives you the headroom you want. Chichester District Council assesses loft proposals against Chichester District Council's adopted local plan and its householder design guidance, 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 Chichester District Council can verify them. The Witterings contains Earnley, Somerley, West Itchenor conservation areas (Earnley designated 1976), 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.
The Witterings also carries protected streets — Earnley, Somerley, West Itchenor and West Wittering among them. No Article 4 direction is recorded for Chichester District Council, but The Witterings's 4 conservation areas still limit permitted development on those streets. We check your address against those designations before a line is drawn.

Many The Witterings 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 Chichester District Council if any of these apply:
We draw the roof line, the ridge height and the neighbour's daylight on the page — the relationships Chichester District 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 Chichester District Council's real householder decision record, pulled from official planning statistics and updated as new data lands. Chichester District Council granted 95% of its householder applications in the year to 31 March 2026, and Earnley shapes what is approved here. 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 Earnley, Somerley and West Itchenor, 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 shallow trussed roofs typical of 1970s building, that is usually the most efficient use of the roof; where the stock is shallow gabled roofs typical of that period's building, a hip-to-gable followed by a rear dormer unlocks far more space, though it needs a full application.
The 5,900 homes here are 13% 1973-1982, 13% 1955-1964, 13% 1930-1939, 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 Chichester District 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 The Witterings roofs come up most often:

The right loft in The Witterings 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 Chichester District 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 Earnley and Somerley and Article 4 directions can remove permitted-development rights.
A fixed process built around how Chichester District Council validates and decides householder loft applications — most drawings are submission-ready within seven days of survey.
Tell us your The Witterings 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 Chichester District 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 Chichester District Council's roof-alteration guidance.
We submit the certificate or application, manage validation and case-officer queries, and revise the drawings free until Chichester District 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 The Witterings the main exceptions are hip-to-gable conversions, dormers visible from the highway, and homes in conservation areas such as Earnley and Somerley or on streets with an Article 4 direction. Chichester District Council is the decision-maker.
Generally no. In conservation areas including Earnley and Somerley, Class B permitted-development rights for lofts are removed, so a rear dormer that would be lawful elsewhere needs a full application to Chichester District Council. No Article 4 direction is recorded for Chichester District Council, but The Witterings's 4 conservation areas still limit permitted development on those streets. We check your exact address before drawing.
On shallow trussed roofs typical of 1970s building, common across The Witterings, a rear dormer is usually the most efficient conversion and often permitted development. Where the roof is shallow gabled roofs typical of that period's 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. Chichester District Council is the decision-maker.
A householder planning application in The Witterings 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. Chichester District Council is the decision-maker.
If your dormer is permitted development, a lawful development certificate from Chichester District 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. This applies to your The Witterings address specifically.
Every roof is different, so we quote each The Witterings project individually — a fixed, no-obligation price back within one working day.
