HMO Conversion Drawings in Ealing
Fixed-fee, MCIAT-chartered hmo conversion drawings for Ealing homeowners — London Borough of Ealing validation and local constraints handled from the start.
Ealing pairs generous Edwardian and Victorian housing stock with some of West London's most protective conservation control, so the right route for an extension or loft depends heavily on where in the borough you are. The stock ranges from Edwardian and Victorian terraces through 1930s Metro-land semi-detached homes in Perivale, Greenford and Northolt to the Arts-and-Crafts houses of Bedford Park. A rear extension in Northolt is a very different application from a roofline change in Bedford Park, and treating them the same is how schemes stall.
The constraints matter early. The London Borough of Ealing operates a borough-wide Article 4 direction removing permitted development rights for HMO conversions, and applies further control to front-garden hardstanding in parts of the borough. Its conservation areas — Bedford Park, Ealing Green, Pitshanger, Hanwell Village Green and St Stephen's — apply strict control over dormers, materials and front elevations, Bedford Park most tightly of all. Mature street trees carry Tree Preservation Orders, and aircraft-noise considerations apply toward the west of the borough, so the address determines the approach.
We prepare Ealing planning drawings to the council's validation standards, checking permitted development eligibility first and designing to Ealing's residential extension guidance so applications are validated without a query. On the Metro-land semis of Perivale and Greenford that usually means confirming a hip-to-gable or dormer loft as permitted development with a Lawful Development Certificate; in Bedford Park and the other conservation areas it means a full householder application designed to the area's character. The fee is fixed and agreed up front, typically around 30% below an architect's charge for the same council-accepted drawings, with free redraws until Ealing approves. Our validation-first approach and roughly seven-day drawing turnaround keep most applications inside the statutory eight-week determination.

HMO Conversion Drawings for Ealing homes: the package and the process
Every hmo conversion drawings we prepare for a Ealing property is drawn to London Borough of Ealing’s validation standards and tuned to the local constraints above. Here is what the drawing package covers and how the process runs from first survey to approval.
A House in Multiple Occupation (HMO) is a property let to three or more unrelated occupants sharing kitchen, bathroom or living facilities. A small HMO — three to six sharers — normally falls into Use Class C4, while a large HMO of seven or more occupants is sui generis, sitting entirely outside the Use Classes Order. Both routes trigger licensing requirements, and in many London boroughs an Article 4 direction removes the usual permitted development right to convert a family home (C3) into a small HMO (C4), meaning full planning permission is needed even for a straightforward conversion.
DrawingsDirect draws HMO conversions to the standard your borough's planning and licensing teams both expect — minimum room sizes, amenity provision, fire safety and means of escape — so one set of drawings supports both the planning application, where needed, and the licensing submission. We check whether an Article 4 direction applies to your property before you commit to a route, and coordinate fire safety and structural detail in-house.
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.
| 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 |
