Planning Permission in Hammersmith and Fulham: 2026 Guide

Why does Hammersmith and Fulham approve 96% of applications?

Partly because so many never reach a decision. The borough approved 96.0% of its householder applications — the highest rate in London, refusing just 62 of 1,569 — while withdrawing 15.9% before determination and agreeing an extension of time on 59.6% of all applications.

Open Government Licence v3.0. The three figures belong together: a borough that negotiates hard, extends the clock and steers weak schemes into withdrawal will report a very high approval rate without being an easy borough to build in.

Planning in Hammersmith and Fulham — what you need to know

Hammersmith and Fulham approves 92.9% of proposals to create new dwellings, the highest rate in London (MHCLG planning statistics, retrieved 1 September 2026). For a borough with 45 conservation areas and an Article 4 Direction that is counter-intuitive, and it is the single most useful thing to know here: converting a Fulham terrace into flats is not the uphill fight the designation count implies. What the borough is strict about is how the outside looks while you do it.

Suburban-feel residential streets with strong conservation area coverage; well-established mansard precedents on many terraces. The borough has a population of approximately 184,000 residents and covers postcodes W6, W12, W14, SW6, SW10.

The housing stock in Hammersmith and Fulham is predominantly victorian and Edwardian terraces — particularly two-storey bay-fronted terraces south of the river in Fulham and Parsons Green; mansion blocks along main roads. This mix of property types means that Hammersmith & Fulham Council deals with a wide range of applications, from rear extensions on terraced houses to loft conversions on semi-detached properties and full refurbishments of period homes in conservation areas.

With 45 designated conservation areas and active Article 4 Directions, Hammersmith and Fulham has a relatively controlled planning environment where Permitted Development rights may be restricted in many areas.

At Architectural Drawings London, we prepare planning drawings and building regulations drawings for properties across all Hammersmith and Fulham postcodes. Our MCIAT chartered architectural technologists have experience with Hammersmith & Fulham Council and understand the specific policies, design guides, and precedents that apply in Hammersmith and Fulham.

Where do Article 4 Directions apply in Hammersmith and Fulham?

Hammersmith and Fulham has Article 4 Directions in place that remove certain Permitted Development rights. Article 4 removes PD for HMO conversions; restrictions on ground-floor shop-to-residential in certain streets.

Article 4 Directions are used by councils to protect the character of an area by requiring planning permission for changes that would otherwise be permitted. If your property is affected by an Article 4 Direction in Hammersmith and Fulham, you will need to submit a full planning application even for works that would normally fall under Permitted Development. The council fee for a householder application is £548, and we prepare the necessary drawings and supporting documents.

It is important to note that Article 4 Directions in Hammersmith and Fulham are separate from conservation area restrictions. A property can be affected by both, and in practice many Article 4 areas overlap with conservation areas. We check the specific restrictions affecting your property as part of our initial assessment.

How much of Hammersmith and Fulham is designated?

Hammersmith and Fulham has 45 designated conservation areas. Notable conservation areas include:

• Hammersmith Grove
• Brackenbury Village
• Fulham Palace Road
• Parsons Green
• Walham Green

In conservation areas, Permitted Development rights are more restricted than in non-designated areas. Key restrictions include:

• No cladding, stone, artificial stone, pebble dash, render, timber, plastic, or tile to any external wall without planning permission
• No side extensions under Permitted Development
• Rear extensions are limited and may require planning permission
• Dormer loft conversions facing the highway require planning permission
• Satellite dishes on front elevations or chimneys are not permitted
• Demolition of gates, walls, fences, or other boundary treatment requires planning permission

Forty-five conservation areas and an Article 4 Direction over housing that is almost entirely repeated frontage. The council served no contravention notices at all in three years (MHCLG planning statistics, retrieved 1 September 2026) — unique among London boroughs and a genuine signal about how it operates: control is exercised at the application stage, not afterwards. That makes getting the submission right the whole game here, since there is little informal correction to fall back on.

Popular projects in Hammersmith and Fulham

Two-storey bay-fronted Victorian and Edwardian terraces run continuously through Fulham and Parsons Green, with mansion blocks along the main roads. The uniformity is the point: mansard precedents on these terraces are well established, so a rear-of-terrace roof addition is arguing from an existing pattern rather than proposing a new one. Across everything the council approved 93.5% of 3,826 decisions (MHCLG planning statistics, retrieved 1 September 2026), second-highest in London.

Loft conversions

Hammersmith and Fulham has extensive streets of terraced housing, making loft conversions one of the most popular home improvement projects in the borough. A rear dormer loft conversion on a typical Victorian or Edwardian mid-terrace can add 20-30 square metres of living space and significant value to the property. In many cases, rear dormers fall under Permitted Development rights, though properties in conservation areas or subject to Article 4 Directions will need full planning permission. We prepare loft conversion drawings for properties across Hammersmith and Fulham.

Side-return and rear extensions

The classic Victorian and Edwardian terrace layout in Hammersmith and Fulham leaves a side return passage that is prime territory for a kitchen extension. A single-storey rear or side-return extension can often be built under Permitted Development, extending up to 6 metres from the rear wall (or up to 8 metres for detached houses under the Prior Approval process). We prepare extension plans for properties across all Hammersmith and Fulham postcodes (W6, W12, W14, SW6, SW10).

Flat conversions and internal alterations

With mansion blocks and converted flats forming part of Hammersmith and Fulham's housing stock, internal layout changes and flat conversions are common projects. While internal alterations rarely need planning permission, converting a house to flats (C3 to C4 HMO) or vice versa may require planning approval, particularly given Hammersmith and Fulham's Article 4 Direction covering HMO conversions. We can prepare the necessary floor plans, elevations, and supporting documents for flat conversion applications in Hammersmith and Fulham.

Mansard roof extensions

Hammersmith and Fulham has established precedents for mansard roof extensions, particularly on Victorian and Edwardian terraces. A mansard conversion replaces the existing roof slope with a near-vertical front and a shallow-sloped top, creating a full additional storey. Mansard extensions always require planning permission. We prepare mansard drawings for properties across Hammersmith and Fulham.

How much do planning drawings cost in Hammersmith and Fulham?

The council charge is small next to the programme risk. Hammersmith and Fulham agreed an extension of time on 59.6% of decisions, the highest share of any borough carrying a full caseload (MHCLG planning statistics, retrieved 1 September 2026), so a submitted application here more often than not runs past the statutory period by agreement. Build that into the schedule from the start. Our drawing fee is one fixed figure set in advance, close to 30% under the London architect rate.

We include a measured survey, existing and proposed plans, elevations, and a site plan — everything required for a valid planning submission to Hammersmith & Fulham Council. Our fees are 30% below typical London architect rates for the same scope of work.

The council issued 260 certificates of lawful development over three years (MHCLG planning statistics, retrieved 1 September 2026), the fourth-lowest count in London, which follows from an Article 4 Direction and 45 conservation areas covering most of the residential borough. If your address is one of the few where permitted development survives, that certificate genuinely distinguishes it at sale.

Why is the approval rate so high, and what does it hide?

96.0%of householder applications granted — the highest of the 32 measurable boroughs

938of the 1,569 householder decisions taken under an extension of time or performance agreement

10larger rear extensions determined under prior approval in three years

119listed building consents decided, and 119 granted

Because in Hammersmith and Fulham the negotiation happens before the decision, not after it. The council decided 1,569 householder applications in the twelve quarters to March 2026 and granted 1,507, refusing 62. No borough grants a higher share. But 938 of those decisions — three in five — were taken under an agreed extension of time or a performance agreement, and a further 15.9% of applications were withdrawn before any decision was made at all. A scheme that would be refused elsewhere is here reshaped over eight or twelve extra weeks until it is grantable, or quietly taken off the table. The rate measures what survives that process, not how easy the process is.

Permitted development barely exists as an option here. Over the same three years the borough determined ten larger rear extensions under the prior approval procedure. Ten. Redbridge determined 1,543. That is far below the thirty-case floor at which a refusal percentage means anything, so this page publishes no prior approval rate for Hammersmith and Fulham — and the absence is the finding. Where a borough is 84.4% built up, where 48.1% of its 95,070 dwellings went up before 1900 against 20.9% across London, and where most of the housing is flats and maisonettes to which Part 1 rights do not extend in the first place, the question of whether a 6m rear extension can be notified rather than applied for almost never arises.

Speed is the cost, and it is a real one. Strip out the decisions taken under an extension of time and 631 householder applications remain, of which 557 were determined inside eight weeks. That is 88.3%, below the 92.5% London figure. Read it with the extension-of-time share beside it: the borough is not often late against its agreed deadline, because the deadline moves.

A refusal here is unusual, and unusually worth appealing. Inspectors decided 230 householder appeals from Hammersmith and Fulham refusals between July 2016 and June 2026 and allowed 98 of them — 42.6%, against 35.6% across England. That is not an approval rate and cannot be read as one: only the refused minority appeals. It does mean that when this council does say no, the reasons stand up rather less often than the national picture would suggest. The borough also recorded 260 certificates of lawful development, the document that proves a completed alteration never needed permission, at £274 against the £548 application fee.
