HMO Conversion Drawings in New Cross SE14
Fixed-fee, MCIAT-chartered hmo conversion drawings for New Cross (SE14) homeowners — London Borough of Lewisham validation and local constraints handled from the start.
New Cross (SE14) climbs from the busy New Cross Road up into the Victorian streets of Telegraph Hill and the terraces behind Hatcham, and our work here is mostly rear extensions, side returns and loft conversions on that period housing.
Both the Telegraph Hill and Hatcham conservation areas carry Article 4 directions, so several normally-permitted changes need consent, and we check the boundary and the direction before advising on a permitted-development or full householder route.
Planning in New Cross (SE14): what to know before you apply
Inside the Telegraph Hill or Hatcham conservation areas the Article 4 directions mean front-facing and roof changes usually need planning permission. We confirm the designation for your street and prepare drawings to Lewisham standards.
Typical New Cross housing stock
Telegraph Hill is a largely residential grid of steep Victorian streets and villas above New Cross, while Hatcham combines commercial frontages on New Cross Road with Victorian terraces behind, plus later flats and student housing.

HMO Conversion Drawings for New Cross (SE14) homes: the package and the process
Every hmo conversion drawings we prepare for an New Cross property is drawn to London Borough of Lewisham’s validation standards and tuned to the SE14 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.
