Flat Conversion Drawings in Fulham SW6
Fixed-fee, MCIAT-chartered flat conversion drawings for Fulham (SW6) homeowners — London Borough of Hammersmith & Fulham validation and local constraints handled from the start.
Fulham (SW6) is one of west London's most consistent late-Victorian terraced neighbourhoods, and rear, side-return and basement projects dominate the workload. Several conservation areas — Parson's Green, Walham Green and Studdridge Street among them — cover large parts of the district, so whether a property sits inside one of those boundaries is the first thing that shapes an extension or loft scheme.
Basements are a defining Fulham project, and Hammersmith & Fulham applies a specific basement development policy controlling depth, structural method and impact on neighbours and trees. We confirm the conservation position and the basement-policy requirements before drawing, and prepare the application and structural drawings to the council's validation and design standards.
Planning in Fulham (SW6): what to know before you apply
SW6 has no householder Article 4 direction affecting typical rear or loft work, but its conservation areas mean permitted development cannot be assumed across much of Fulham, and Hammersmith & Fulham's basement development policy adds a further layer of control for the deep basements common here — both are checked at the outset.
Typical Fulham housing stock
Dense late-Victorian terraces across the Fulham 'streets' — the Peterborough Estate 'Lion houses' and the alphabet roads off New Kings Road — plus Edwardian mansion blocks around Parsons Green and newer riverside development toward the Thames.

Flat Conversion Drawings for Fulham (SW6) homes: the package and the process
Every flat conversion drawings we prepare for an Fulham property is drawn to London Borough of Hammersmith & Fulham’s validation standards and tuned to the SW6 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.
