Dormer, hip-to-gable and mansard loft conversion drawings for Hammersmith and Fulham homes — prepared to Hammersmith & Fulham Council's design guidance, delivered in days and revised free until your decision lands, with a free approval-odds score first.
Hammersmith & Fulham Council granted 87% of the householder planning decisions it made in its latest published year — level with the 87% England-wide householder average. Basement schemes require a detailed basement impact assessment covering ground stability, flooding and construction management, which is where a policy-literate drawing pack earns its keep. Its dominant Victorian (1837–1901) and Edwardian (1901–1910) housing stock sets the design brief on most streets.
The permitted-development ceilings are fixed: 40m³ of new roof volume for a terraced loft and 50m³ for a semi or detached house under Class B, plus a 3m single-storey rear extension on a terrace or 4m on a detached house under Class A. Hammersmith and Fulham carries at least one Article 4 direction, and conservation areas including Brackenbury, Bradmore and Peterborough Estate remove those rights outright, so we confirm your exact address before a line is drawn. A validated householder application in Hammersmith and Fulham is determined against an 8-week statutory target.
Hammersmith (Victorian terraces around the Brackenbury village grid), Fulham (the Peterborough Estate 'Lion' houses and Hurlingham mansion flats), Shepherd's Bush (dense Victorian terraces, much of it split into flats), Brook Green (Edwardian terraces interspersed with mansion blocks), Parsons Green (Victorian terraces gathered around the green) and Sands End (former industrial land now mixing terraces with new housing) — these are the Hammersmith and Fulham pockets our drawings cover most. Heritage designations here include Brackenbury, Bradmore, Peterborough Estate, Ravenscourt and Wendell Park. Hammersmith & Fulham Council weighs each proposal against Hammersmith and Fulham Local Plan and the Planning Guidance SPD, where with terraces packed tightly, mansard and side-return proposals turn on protecting a consistent roofline and rear amenity. Converted flats dominate large parts of Shepherd's Bush and Fulham, and none carry householder permitted-development rights.. On roofs the borough is London butterfly roofs concealed behind the terrace parapets and back-addition closet-wing roofs that shape side-return schemes, over Victorian and Edwardian terraces, purpose-built mansion flats and converted period flats.
Hammersmith and Fulham's roofs set the brief. The borough is built largely from Victorian and Edwardian terraces, purpose-built mansion flats and converted period flats, and its lofts sit under London butterfly roofs concealed behind the terrace parapets and back-addition closet-wing roofs that shape side-return schemes — the geometry that decides whether a rear dormer, a hip-to-gable or a mansard gives you the headroom you want. Hammersmith & Fulham Council assesses loft proposals against Hammersmith and Fulham Local Plan and the Planning Guidance SPD, 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 Hammersmith & Fulham Council can verify them. Basement schemes require a detailed basement impact assessment covering ground stability, flooding and construction management, so we resolve it on the page rather than leave it for the case officer to raise.
Hammersmith and Fulham also carries protected streets — Brackenbury, Bradmore, Peterborough Estate, Ravenscourt and Wendell Park among them. Conservation areas blanket much of the borough — Brackenbury, Bradmore and the Fulham Peterborough Estate among them — and Article 4 directions there remove permitted-development rights on frontages and roofs. We check your address against those designations before a line is drawn.
Many Hammersmith and Fulham 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 Hammersmith & Fulham Council if any of these apply:
We draw the roof line, the ridge height and the neighbour's daylight on the page — the relationships Hammersmith & Fulham 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 Hammersmith & Fulham Council's real householder decision record, pulled from official planning statistics and updated as new data lands. Hammersmith and Fulham grants a high share of householder applications, though tight terrace density and basement engineering are the constraints that shape most designs. 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 Hammersmith, Fulham and Shepherd's Bush, 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 London butterfly roofs concealed behind the terrace parapets, that is usually the most efficient use of the roof; where the stock is back-addition closet-wing roofs that shape side-return schemes, a hip-to-gable followed by a rear dormer unlocks far more space, though it needs a full application.
With terraces packed tightly, mansard and side-return proposals turn on protecting a consistent roofline and rear amenity. 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 Hammersmith & Fulham 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 Hammersmith and Fulham roofs come up most often:

The right loft in Hammersmith and Fulham 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 Hammersmith & Fulham 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 Brackenbury and Bradmore and Article 4 directions can remove permitted-development rights.

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 Hammersmith & Fulham Council's roof-alteration guidance.
We submit the certificate or application, manage validation and case-officer queries, and revise the drawings free until Hammersmith & Fulham 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 Hammersmith and Fulham the main exceptions are hip-to-gable conversions, dormers visible from the highway, and homes in conservation areas such as Brackenbury and Bradmore or on streets with an Article 4 direction. Hammersmith & Fulham Council is the decision-maker.
Generally no. In conservation areas including Brackenbury and Bradmore, Class B permitted-development rights for lofts are removed, so a rear dormer that would be lawful elsewhere needs a full application to Hammersmith & Fulham Council. Conservation areas blanket much of the borough — Brackenbury, Bradmore and the Fulham Peterborough Estate among them — and Article 4 directions there remove permitted-development rights on frontages and roofs. We check your exact address before drawing. This applies to your Hammersmith and Fulham address specifically.
On London butterfly roofs concealed behind the terrace parapets, common across Hammersmith and Fulham, a rear dormer is usually the most efficient conversion and often permitted development. Where the roof is back-addition closet-wing roofs that shape side-return schemes, 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. Hammersmith & Fulham Council is the decision-maker.
A householder planning application in Hammersmith and Fulham 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. Hammersmith & Fulham Council is the decision-maker.
If your dormer is permitted development, a lawful development certificate from Hammersmith & Fulham 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 Hammersmith and Fulham address specifically.
