HMO Conversion Drawings in Kennington SE11
Fixed-fee, MCIAT-chartered hmo conversion drawings for Kennington (SE11) homeowners — London Borough of Lambeth validation and local constraints handled from the start.
Kennington SE11 is a tight grid of late-Georgian and early-Victorian terraces a short walk from the Oval, where most homeowners look to rear kitchen extensions and loft conversions to add space without altering the protected street frontage.
Because the Kennington and Walcot Conservation Areas cover much of the outcode, we always confirm which boundary a property sits inside before advising permitted development versus a full householder application — conservation-area status quietly removes several rights a comparable house outside would keep.
Planning in Kennington (SE11): what to know before you apply
Most Kennington projects run as full householder applications to Lambeth given the conservation-area coverage, with rear extensions and rooflight lofts the usual approvable route. Front and roof changes need the closest attention. We check the exact CA boundary and any listing before choosing the route.
Typical Kennington housing stock
Smart brick terraces that grew from the late 18th century onward, including the Georgian set pieces around Cleaver Square. Many are three- and four-storey flat-fronted houses, now often split into flats or run as family homes with scope for rear and lower-ground extensions.

HMO Conversion Drawings for Kennington (SE11) homes: the package and the process
Every hmo conversion drawings we prepare for an Kennington property is drawn to London Borough of Lambeth’s validation standards and tuned to the SE11 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.
