HMO Conversion Drawings in Perivale UB6
Fixed-fee, MCIAT-chartered hmo conversion drawings for Perivale (UB6) homeowners — London Borough of Ealing validation and local constraints handled from the start.
Perivale (UB6) is a well-preserved 1930s suburb of matching semis on curving avenues, where the bread-and-butter work is rear kitchen extensions, hip-to-gable loft conversions and rear dormers. The uniformity of the streetscape means Ealing's officers care about how a proposal reads against its neighbours, so faithful detailing matters more here than in a mixed-age street.
Perivale also sits in the orbit of the Art Deco Hoover Building on Western Avenue and the green ridge of Horsenden Hill, and the Canalside conservation area clips its north-west edge. We design extensions that echo the original bay, render and roof pitch, and we check tree cover and the canal-side boundary so schemes reach Ealing's approval standard first time.


Planning in Perivale (UB6): what to know before you apply
No published householder Article 4 direction in Perivale, so most householder work proceeds under permitted development or a standard Ealing application. Homes near the Canalside conservation area or backing onto Horsenden Hill's open space face tighter scrutiny on materials, roof form and tree protection.
Typical Perivale housing stock
Perivale is a planned interwar suburb of consistent 1930s semis and short terraces, many with curved bays, rendered gables and hipped tiled roofs, arranged on gently curving crescents. Streets rising towards Horsenden Hill keep deep rear gardens well suited to single-storey extensions and loft dormers.

HMO Conversion Drawings for Perivale (UB6) homes: the package and the process
Every hmo conversion drawings we prepare for an Perivale property is drawn to London Borough of Ealing’s validation standards and tuned to the UB6 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.
