Dormer, hip-to-gable and mansard loft conversion drawings for Cranleigh West homes — prepared to Waverley Borough Council's design guidance, delivered in days and revised free until your decision lands, with a free approval-odds score first.
Waverley Borough Council granted 93% of the householder planning decisions it made in its latest published year — 6 points above the 87% England-wide householder average. Cranleigh West contains the CRANLEIGH conservation area (CRANLEIGH designated 1973), 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. Cranleigh West carries at least one Article 4 direction, and conservation areas including CRANLEIGH remove those rights outright, so we confirm your exact address before a line is drawn. A validated householder application in Cranleigh West is determined against an 8-week statutory target.
CRANLEIGH (conservation area designated in 1973) and Cranleigh (civil parish within Cranleigh West) — these are the Cranleigh West pockets our drawings cover most. Heritage designations here include CRANLEIGH. Waverley Borough Council weighs each proposal against Waverley Borough Council's adopted local plan and its householder design guidance, where the 2,810 homes here are 13% 1965-1972, 9% pre-1900, 9% 1983-1992, which is what sets the realistic roof and rear-projection options. On roofs the borough is shallow-pitched roofs and integral garages typical of that period's building and steeply pitched slate roofs, valley gutters and party parapets typical of pre-1900 building, over late-1960s and early-1970s houses (13% of 2,810 homes), Victorian and earlier houses (9%) and 1980s estate houses (9%).
What is permitted in Cranleigh West turns on designation first, so that is where we start: CRANLEIGH (conservation area designated in 1973). Inside those boundaries permitted development is curtailed and Waverley 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, Cranleigh West takes in Cranleigh. Waverley Borough Council has 26 recorded Article 4 directions, removing permitted development for rear and side extensions and other roof alterations, including rooflights — check the address before assuming PD applies in Cranleigh West.
On stock, Cranleigh West is late-1960s and early-1970s houses (13% of 2,810 homes), Victorian and earlier houses (9%) and 1980s estate houses (9%) — which is why shallow-pitched roofs and integral garages 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. Waverley Borough Council decided 884 householder applications in the latest published year and granted 93%, with 66% issued inside the eight-week target. We draw to that record rather than to a national average.
The full build-period split for Cranleigh West runs pre-1900 9% (260 homes), 1900-1918 5% (140 homes), 1919-1929 2% (50 homes), 1930-1939 7% (200 homes), 1945-1954 3% (80 homes), 1955-1964 3% (90 homes), 1965-1972 13% (360 homes), 1973-1982 7% (190 homes), 1983-1992 9% (260 homes), 1993-1999 1% (20 homes) and 2000-2008 2% (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.
Waverley Borough Council also decides for Bramley & Wonersh, Chiddingfold, Elstead & Peper Harow, Ewhurst & Ellens Green, Farnham Bourne, Farnham Castle, Farnham Moor Park and Farnham Rowledge, so a decision in Cranleigh West 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 Beacon Hill Commercial Area (2022), Buildings Wood, Horsham Road, Ewhurst (1961), Farnham Trading Estate, Water Lane, Farnham (1965) and Godalming Station Commercial Area (2022). 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.

Cranleigh West's roofs set the brief. The borough is built largely from late-1960s and early-1970s houses (13% of 2,810 homes), Victorian and earlier houses (9%) and 1980s estate houses (9%), and its lofts sit under shallow-pitched roofs and integral garages typical of that period's building and steeply pitched slate roofs, valley gutters and party parapets typical of pre-1900 building — the geometry that decides whether a rear dormer, a hip-to-gable or a mansard gives you the headroom you want. Waverley Borough Council assesses loft proposals against Waverley Borough 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 Waverley Borough Council can verify them. Cranleigh West contains the CRANLEIGH conservation area (CRANLEIGH designated 1973), 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.
Cranleigh West also carries protected streets — CRANLEIGH among them. Waverley Borough Council has 26 recorded Article 4 directions, removing permitted development for rear and side extensions and other roof alterations, including rooflights — check the address before assuming PD applies in Cranleigh West. We check your address against those designations before a line is drawn.
Many Cranleigh West 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 Waverley 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 Waverley 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 Waverley Borough Council's real householder decision record, pulled from official planning statistics and updated as new data lands. Waverley Borough Council granted 93% of its householder applications in the year to 31 March 2026, and CRANLEIGH 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 CRANLEIGH and Cranleigh, 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-pitched roofs and integral garages typical of that period's building, that is usually the most efficient use of the roof; where the stock is steeply pitched slate roofs, valley gutters and party parapets typical of pre-1900 building, a hip-to-gable followed by a rear dormer unlocks far more space, though it needs a full application.
The 2,810 homes here are 13% 1965-1972, 9% pre-1900, 9% 1983-1992, 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 Waverley 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 Cranleigh West roofs come up most often:

The right loft in Cranleigh West 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 Waverley 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 CRANLEIGH and Article 4 directions can remove permitted-development rights.
A fixed process built around how Waverley Borough Council validates and decides householder loft applications — most drawings are submission-ready within seven days of survey.
Tell us your Cranleigh West 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 Waverley 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 Waverley Borough Council's roof-alteration guidance.
We submit the certificate or application, manage validation and case-officer queries, and revise the drawings free until Waverley 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 Cranleigh West the main exceptions are hip-to-gable conversions, dormers visible from the highway, and homes in conservation areas such as CRANLEIGH or on streets with an Article 4 direction. Waverley Borough Council is the decision-maker.
Generally no. In conservation areas including CRANLEIGH, Class B permitted-development rights for lofts are removed, so a rear dormer that would be lawful elsewhere needs a full application to Waverley Borough Council. Waverley Borough Council has 26 recorded Article 4 directions, removing permitted development for rear and side extensions and other roof alterations, including rooflights — check the address before assuming PD applies in Cranleigh West. We check your exact address before drawing.
On shallow-pitched roofs and integral garages typical of that period's building, common across Cranleigh West, a rear dormer is usually the most efficient conversion and often permitted development. Where the roof is steeply pitched slate roofs, valley gutters and party parapets typical of pre-1900 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. Waverley Borough Council is the decision-maker.
A householder planning application in Cranleigh West 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. Waverley Borough Council is the decision-maker.
If your dormer is permitted development, a lawful development certificate from Waverley 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. This applies to your Cranleigh West address specifically.
Every roof is different, so we quote each Cranleigh West project individually — a fixed, no-obligation price back within one working day.
