Dormer, hip-to-gable and mansard loft conversion drawings for Reigate & Banstead homes — prepared to Reigate & Banstead Borough Council's design guidance, delivered in days and revised free until your decision lands, with a free approval-odds score first.
Reigate & Banstead Borough Council granted 87% of the householder planning decisions it made in its latest published year — level with the 87% England-wide householder average. A double landscape constraint applies in the south, combining Metropolitan Green Belt with the Surrey Hills Area of Outstanding Natural Beauty, 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.
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 Reigate & Banstead Borough Council needs a full application. Reigate & Banstead carries at least one Article 4 direction, and conservation areas including Reigate, Redhill and Banstead Village remove those rights outright, so we confirm your exact address before a line is drawn. A validated householder application in Reigate & Banstead is determined against an 8-week statutory target.
Reigate (historic market town with Victorian and Edwardian conservation cores), Redhill (a Victorian railway-junction town with postwar and new-build regeneration), Banstead (low-density 1930s interwar semis around a village core), Horley (a southern town of postwar and ongoing new-build estates), Merstham (Victorian terraces alongside the postwar New Merstham estates) and Nutfield (a rural village in the Green Belt and Surrey Hills setting) — these are the Reigate & Banstead pockets our drawings cover most. Heritage designations here include Reigate, Redhill, Banstead Village, Reigate Heath, Nutfield and Merstham. Reigate & Banstead Borough Council weighs each proposal against the Reigate & Banstead Core Strategy (adopted 2014) and Development Management Plan (adopted 2019), where the 2019 Development Management Plan released nine Green Belt sites as sustainable urban extensions for around 845 homes, a notable managed release. Flats are a meaningful share of stock in the Redhill and Reigate town centres and at Merstham, and converted flats hold no householder permitted-development rights.. On roofs the borough is pitched clay and concrete-tile gabled and hipped roofs on the interwar semis and steeper tiled roofs on the Victorian mansions of Reigate Hill and Wray Common, over Victorian and Edwardian streets in Reigate and around Redhill's railway junction, abundant low-density 1930s interwar semis in Banstead, postwar and modern estate housing in Redhill, Horley and Merstham and village vernacular in the rural Green Belt and Surrey Hills settlements.
Reigate & Banstead's roofs set the brief. The borough is built largely from Victorian and Edwardian streets in Reigate and around Redhill's railway junction, abundant low-density 1930s interwar semis in Banstead, postwar and modern estate housing in Redhill, Horley and Merstham and village vernacular in the rural Green Belt and Surrey Hills settlements, and its lofts sit under pitched clay and concrete-tile gabled and hipped roofs on the interwar semis and steeper tiled roofs on the Victorian mansions of Reigate Hill and Wray Common — the geometry that decides whether a rear dormer, a hip-to-gable or a mansard gives you the headroom you want. Reigate & Banstead Borough Council assesses loft proposals against the Reigate & Banstead Core Strategy (adopted 2014) and Development Management Plan (adopted 2019), 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 Reigate & Banstead Borough Council can verify them. A double landscape constraint applies in the south, combining Metropolitan Green Belt with the Surrey Hills Area of Outstanding Natural Beauty, so we resolve it on the page rather than leave it for the case officer to raise.
Reigate & Banstead also carries protected streets — Reigate, Redhill, Banstead Village, Reigate Heath, Nutfield and Merstham among them. An Article 4 direction in force from February 2026 removes the permitted right to change ground-floor commercial units to residential across the borough's town and local centres, protecting retail and services frontages. We check your address against those designations before a line is drawn.
Many Reigate & Banstead 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 Reigate & Banstead 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 Reigate & Banstead 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 Reigate & Banstead Borough Council's real householder decision record, pulled from official planning statistics and updated as new data lands. Reigate & Banstead grants a fair share of householder applications broadly at the national norm, higher than the most heavily green-belted Surrey neighbours, with the AONB and Green Belt the main constraints in the south. 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 Reigate, Redhill and Banstead, 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 pitched clay and concrete-tile gabled and hipped roofs on the interwar semis, that is usually the most efficient use of the roof; where the stock is steeper tiled roofs on the Victorian mansions of Reigate Hill and Wray Common, a hip-to-gable followed by a rear dormer unlocks far more space, though it needs a full application.
The 2019 Development Management Plan released nine Green Belt sites as sustainable urban extensions for around 845 homes, a notable managed release. 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 Reigate & Banstead 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 Reigate & Banstead roofs come up most often:

The right loft in Reigate & Banstead 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 Reigate & Banstead 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 Reigate and Redhill and Article 4 directions can remove permitted-development rights.
A fixed process built around how Reigate & Banstead Borough Council validates and decides householder loft applications — most drawings are submission-ready within seven days of survey.
Tell us your Reigate & Banstead 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 Reigate & Banstead 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 Reigate & Banstead Borough Council's roof-alteration guidance.
We submit the certificate or application, manage validation and case-officer queries, and revise the drawings free until Reigate & Banstead 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 Reigate & Banstead the main exceptions are hip-to-gable conversions, dormers visible from the highway, and homes in conservation areas such as Reigate and Redhill or on streets with an Article 4 direction. Reigate & Banstead Borough Council is the decision-maker.
Generally no. In conservation areas including Reigate and Redhill, Class B permitted-development rights for lofts are removed, so a rear dormer that would be lawful elsewhere needs a full application to Reigate & Banstead Borough Council. An Article 4 direction in force from February 2026 removes the permitted right to change ground-floor commercial units to residential across the borough's town and local centres, protecting retail and services frontages. We check your exact address before drawing.
On pitched clay and concrete-tile gabled and hipped roofs on the interwar semis, common across Reigate & Banstead, a rear dormer is usually the most efficient conversion and often permitted development. Where the roof is steeper tiled roofs on the Victorian mansions of Reigate Hill and Wray Common, 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. Reigate & Banstead Borough Council is the decision-maker.
A householder planning application in Reigate & Banstead 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. Reigate & Banstead Borough Council is the decision-maker.
If your dormer is permitted development, a lawful development certificate from Reigate & Banstead 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.
