Earl's Court (SW5) is a district of grand stucco garden-square terraces — Earl's Court Square, Nevern Square and Philbeach Gardens — most of them converted into mansion and conversion flats. Projects here are typically flat reconfigurations, rear-closet and lower-ground alterations, and lightwell or modest basement works rather than whole-house extensions.

As the terraces fall within RBKC conservation areas and are largely in multiple occupation, we prepare drawings that respect the uniform stucco frontages and coordinate the leasehold and party-wall realities of flats, meeting the Royal Borough of Kensington and Chelsea's standard on external detail and subterranean control.

Planning in Earl's Court (SW5): what to know before you apply

There is no published householder Article 4 direction, but conservation-area status across SW5 withdraws most permitted-development rights and shapes what flat and rear alterations are acceptable. RBKC's subterranean development policy applies to lightwells and lower-ground excavation.

Typical Earl's Court housing stock

SW5 is characterised by tall stucco-fronted Victorian terraces set around Earl's Court Square, Nevern Square and Philbeach Gardens, the majority long since divided into mansion and conversion flats. Because whole houses are rare, work here is dominated by flat reconfigurations, rear-closet and lower-ground alterations, and lightwell or modest basement schemes.

Flat Conversion Drawings for Earl's Court (SW5) homes: the package and the process

Every flat conversion drawings we prepare for an Earl's Court property is drawn to Royal Borough of Kensington and Chelsea’s validation standards and tuned to the SW5 constraints above. Here is what the drawing package covers and how the process runs from first survey to approval.

Converting a house into flats is one of the few residential projects in London that always needs planning permission, whatever the size of the property or the number of units created. Splitting a single dwelling into two or more self-contained homes is treated as development regardless of whether any external work is proposed, because the change affects how the building is used and how many households occupy it.

DrawingsDirect draws house-to-flats conversions from the first survey through to a submission-ready planning and building-regulations package. Sound insulation between units, separate escape routes, individual services and London's minimum space standards are designed in from the layout stage, not retrofitted once the council asks for them — which is a large part of why our schemes are approved first time.

Do I need planning permission to convert a house into flats?

Yes, always. Converting a single dwelling into two or more self-contained flats is a change from one home to several, and that subdivision is treated as development requiring a full planning application — there is no permitted development route that allows it, regardless of the property's size or whether the exterior changes at all. The application has to demonstrate that each flat meets space, layout, amenity and parking standards in its own right, not just that the building as a whole is being used sensibly.

Boroughs also weigh the loss of a family-sized house against their local housing policy, since converting a larger house into several flats reduces the stock of homes suited to families even as it adds smaller units. We take that policy context into account when advising on layout and unit numbers, rather than simply maximising the number of flats the floor area could technically support.

What sound insulation is required between flats?

Part E of the building regulations sets minimum sound insulation standards for the walls and floors separating flats, covering both airborne and impact sound. Where an existing house is subdivided, the drawings specify how the party floors and walls between units will be upgraded — additional layers, resilient bars, or a floating floor — and pre-completion sound testing is normally required before the flats can be signed off. Getting this detail right on the drawings from the outset matters, because retrofitting sound insulation after a failed test usually means taking up a finished floor or ceiling that has already been decorated.

FAQ

Flat Conversion Drawings in Earl's Court SW5 — FAQs

Do I need planning permission to convert a house into flats?+
Yes, always. Subdividing a single dwelling into two or more self-contained flats is treated as development in its own right, so a full planning application is required regardless of whether the exterior of the building changes.
How much do flat conversion drawings cost in London?+
Packages start from £1,600 for converting a house into two flats and rise to around £2,800 where three or more units, structural work or an extension are involved. We agree a fixed fee once we know the scope.
What sound insulation is required between flats?+
Part E of the building regulations sets minimum airborne and impact sound standards for the floors and walls separating flats, and pre-completion sound testing is normally required before the units can be signed off.
Does each flat need a separate fire escape?+
Each flat needs its own means of escape and the building needs to be fire-compartmented between units, using fire-rated floors, walls and doors and either a protected shared stairway or separate final exits.
What is the minimum size for a flat in London?+
London applies minimum internal floor areas based on bedroom and occupancy numbers, adopted from the national space standards through the London Plan. We check every proposed flat against the relevant threshold before drawing the layout.
Do I need planning permission for works in Kensington & Chelsea?+
Almost always. Near-comprehensive conservation-area coverage and a high density of listed buildings mean a full planning application — and often listed-building consent — is usually required even for modest works. Permitted development can rarely be assumed here. We confirm the exact designations and listing status for your address before any design begins.
Can I build a basement in Kensington & Chelsea?+
Within limits. The borough's basements policy is nationally known for restricting new basements — generally to a single storey — and controlling excavation extent, alongside a basement impact assessment. A basement can still be viable, but it must be designed to the policy from the outset. We confirm what your site allows and evidence the scheme accordingly.
My home is listed — what consent do I need?+
Listed-building consent is usually required alongside or instead of planning permission, and internal as well as external changes can be controlled. Given the borough's extensive listed-building coverage across Kensington, Chelsea and the mews, we screen listing status first and prepare the heritage-led drawings and justification the council expects.
How long does the Royal Borough take to decide?+
The council determines most householder applications within the statutory eight-week period once validated, though listed-building, basement and conservation cases frequently attract additional consultation. We prepare submissions to the borough's exacting validation and design standards to avoid the drawing queries that cause most delays.
How much do planning drawings cost in Kensington & Chelsea?+
We agree a fixed fee before starting, typically around 30% below an architect's fee for the same council-accepted drawings, with free redraws until the council approves. Heritage-led and listed-building schemes require more evidence than a standard extension, so we quote once we understand your address and scheme rather than by the hour.
