Dormer, hip-to-gable and mansard loft conversion drawings for Tandridge homes — prepared to Tandridge District Council's design guidance, delivered in days and revised free until your decision lands, with a free approval-odds score first.
Tandridge District Council granted 87% of the householder planning decisions it made in its latest published year — level with the 87% England-wide householder average. Metropolitan Green Belt covers around 94% of the district, one of the highest proportions in England, so the presumption against inappropriate development dominates decisions, which is where a policy-literate drawing pack earns its keep. Its dominant Victorian (1837–1901), Edwardian (1901–1910), 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. Tandridge carries at least one Article 4 direction, and conservation areas including Oxted, Limpsfield and Godstone remove those rights outright, so we confirm your exact address before a line is drawn. A validated householder application in Tandridge is determined against an 8-week statutory target.
Oxted (the principal town with railway-era Victorian and Edwardian housing, twentieth-century growth and a conservation area), Caterham (the district's largest settlement, dense Victorian-to-postwar housing across Caterham-on-the-Hill and the Valley), Warlingham (a hilltop commuter village of largely interwar and postwar detached houses and semis), Godstone (a historic green-belt village around a pond and green with a conservation area), Limpsfield (an affluent AONB-edge village of period and large detached stock with a conservation area) and Lingfield (a historic rural village with a medieval core and a conservation area) — these are the Tandridge pockets our drawings cover most. Heritage designations here include Oxted, Limpsfield, Godstone, Bletchingley, Lingfield and Chaldon. Tandridge District Council weighs each proposal against the Tandridge District Core Strategy (adopted 2008) and Local Plan Part 2: Detailed Policies (adopted July 2014), where the Surrey Hills and High Weald National Landscapes (AONBs) affect the district around Limpsfield, Oxted and the south, adding national landscape protection. Converted flats appear around Oxted and Caterham, and none of them hold householder permitted-development rights.. On roofs the borough is dual-pitch tiled roofs on the railway-era terraces and villas and hipped roofs on the interwar and postwar semis, over Victorian and Edwardian and interwar railway-era housing in Oxted and Caterham, postwar suburban semis and detached houses, large detached houses on generous plots at Woldingham and Limpsfield and historic vernacular cottages in the green-belt villages of Godstone, Bletchingley and Lingfield.
Tandridge's roofs set the brief. The borough is built largely from Victorian and Edwardian and interwar railway-era housing in Oxted and Caterham, postwar suburban semis and detached houses, large detached houses on generous plots at Woldingham and Limpsfield and historic vernacular cottages in the green-belt villages of Godstone, Bletchingley and Lingfield, and its lofts sit under dual-pitch tiled roofs on the railway-era terraces and villas and hipped roofs on the interwar and postwar semis — the geometry that decides whether a rear dormer, a hip-to-gable or a mansard gives you the headroom you want. Tandridge District Council assesses loft proposals against the Tandridge District Core Strategy (adopted 2008) and Local Plan Part 2: Detailed Policies (adopted July 2014), 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 Tandridge District Council can verify them. Metropolitan Green Belt covers around 94% of the district, one of the highest proportions in England, so the presumption against inappropriate development dominates decisions, so we resolve it on the page rather than leave it for the case officer to raise.
Tandridge also carries protected streets — Oxted, Limpsfield, Godstone, Bletchingley, Lingfield and Chaldon among them. Tandridge has Article 4 directions removing permitted-development rights in parts of the district, which owners can check against the council's constraints map before assuming suburban PD rights, and its conservation areas such as Oxted, Limpsfield and Godstone add further character controls. We check your address against those designations before a line is drawn.
Many Tandridge 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 Tandridge 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 Tandridge 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 Tandridge District Council's real householder decision record, pulled from official planning statistics and updated as new data lands. Tandridge grants a fair share of applications broadly in line with the national picture, with overwhelming Green Belt coverage and AONB protection the pressures on anything beyond modest householder work. 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 Oxted, Caterham and Warlingham, 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 dual-pitch tiled roofs on the railway-era terraces and villas, that is usually the most efficient use of the roof; where the stock is hipped roofs on the interwar and postwar semis, a hip-to-gable followed by a rear dormer unlocks far more space, though it needs a full application.
The Surrey Hills and High Weald National Landscapes (AONBs) affect the district around Limpsfield, Oxted and the south, adding national landscape protection. 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 Tandridge 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 Tandridge roofs come up most often:

The right loft in Tandridge 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 Tandridge 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 Oxted and Limpsfield and Article 4 directions can remove permitted-development rights.
A fixed process built around how Tandridge District Council validates and decides householder loft applications — most drawings are submission-ready within seven days of survey.
Tell us your Tandridge 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 Tandridge 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 Tandridge District Council's roof-alteration guidance.
We submit the certificate or application, manage validation and case-officer queries, and revise the drawings free until Tandridge 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 Tandridge the main exceptions are hip-to-gable conversions, dormers visible from the highway, and homes in conservation areas such as Oxted and Limpsfield or on streets with an Article 4 direction. Tandridge District Council is the decision-maker.
Generally no. In conservation areas including Oxted and Limpsfield, Class B permitted-development rights for lofts are removed, so a rear dormer that would be lawful elsewhere needs a full application to Tandridge District Council. Tandridge has Article 4 directions removing permitted-development rights in parts of the district, which owners can check against the council's constraints map before assuming suburban PD rights, and its conservation areas such as Oxted, Limpsfield and Godstone add further character controls. We check your exact address before drawing.
On dual-pitch tiled roofs on the railway-era terraces and villas, common across Tandridge, a rear dormer is usually the most efficient conversion and often permitted development. Where the roof is hipped roofs on the interwar and postwar semis, 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. Tandridge District Council is the decision-maker.
A householder planning application in Tandridge 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. Tandridge District Council is the decision-maker.
If your dormer is permitted development, a lawful development certificate from Tandridge 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.
