HMO Conversion Drawings in Fulham SW6
Fixed-fee, MCIAT-chartered hmo 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.

HMO Conversion Drawings for Fulham (SW6) homes: the package and the process
An HMO scheme is drawn against a schedule. Every bedroom is dimensioned with its usable floor area stated, shared kitchen and bathroom provision is counted against the number of occupants, and the layout has to hold up against the space standards the licensing team applies.
The fire strategy is drawn, not described: protected escape route, fire doors and their ratings, alarm coverage by room, and compartmentation between floors. Licensing and building control assess the same drawing set from different angles, so it has to satisfy both without contradiction.
Room count is a function of the existing plan. A large semi or detached house with generous rooms can meet the space standards without subdivision, while a narrow terrace usually cannot reach the same occupancy without creating rooms that fall below the minimum floor area.
C4 small HMO or sui generis large HMO — which applies to your property?
The distinction matters because it decides which rules apply. A small HMO housing three to six unrelated sharers who share amenities is Class C4. A large HMO of seven or more occupants is sui generis and always needs planning permission, since sui generis uses sit outside the permitted development system entirely. The line also shifts with occupancy — a property let to six sharers today can tip into sui generis territory the moment a seventh tenancy is signed, which changes the planning position even though nothing about the building itself has changed. We assess your proposed occupancy and layout against both definitions before drawing, so the application matches how the property will actually be let.
Do I need planning permission for an HMO conversion in London?
Converting a family home (C3) into a small HMO (C4) is technically permitted development under national rules, but a large number of London boroughs have made an Article 4 direction that removes this right across all or part of the borough — meaning a full planning application is required even for a small, compliant HMO. Article 4 directions vary street by street in some boroughs, so two similar houses a few doors apart can sit on opposite sides of the line. Any large HMO (sui generis) needs planning permission everywhere, regardless of Article 4. We check your specific address against the relevant borough's Article 4 direction before recommending a route, since guessing wrong wastes both time and application fees.
Mandatory and additional HMO licensing — what's required?
Most HMOs need a licence from the council, separate from any planning permission. A licence application typically has to demonstrate that the property meets fire safety, amenity and space standards, that gas and electrical installations are safety-certified, and that the landlord or managing agent is a fit and proper person to hold it.
Mandatory licensing
Applies to any HMO of five or more occupants forming two or more households, regardless of the number of storeys — a national requirement in every London borough.
Additional licensing
Many boroughs extend licensing to smaller HMOs, typically three or four occupants, across all or part of their area. We check the current scheme for your borough before you apply, since schemes and boundaries change.
| Factor | C4 small HMO (3–6 sharers) | Sui generis large HMO (7+) |
|---|---|---|
| Use class | C4 | Sui generis |
| Planning permission | Often needed due to Article 4 directions in most boroughs | Always needed |
| Licensing | Mandatory if 5+ occupants; additional licensing in many boroughs | Mandatory |
| Typical drawing package | From £1,400 | Full planning + building regs, from £2,200 |
