HMO Conversion Drawings in Nunhead SE15
Fixed-fee, MCIAT-chartered hmo conversion drawings for Nunhead (SE15) homeowners — London Borough of Southwark validation and local constraints handled from the start.
Nunhead (SE15) is a largely Victorian terraced neighbourhood on the rising ground between Nunhead Cemetery and Peckham Rye, and as the area has gentrified the demand has shifted firmly toward side-return, rear and loft extensions on family houses. Because so many properties share the same terraced footprint, Southwark's design expectations for extension depth and dormers here are well established.
Conservation pockets around Nunhead Cemetery, Nunhead Green and Telegraph Hill bring tighter control over roof form, materials and frontages than the surrounding streets carry. We check where a Nunhead property sits relative to those boundaries before recommending a permitted-development or full-application route, and draw the scheme to Southwark's residential guidance so it is assessed cleanly.
Planning in Nunhead (SE15): what to know before you apply
SE15 has no published householder Article 4 direction affecting typical Nunhead work, so many houses retain permitted development rights for rear and loft projects — but the conservation pockets around Nunhead Cemetery, Nunhead Green and Telegraph Hill are the exceptions where roof and frontage changes are more closely controlled.
Typical Nunhead housing stock
Victorian and Edwardian terraces on the streets rising between Nunhead Cemetery and Peckham Rye, largely two-storey family houses with rear gardens, plus a share of houses converted into flats.

HMO Conversion Drawings for Nunhead (SE15) homes: the package and the process
Every hmo conversion drawings we prepare for an Nunhead property is drawn to London Borough of Southwark’s validation standards and tuned to the SE15 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.
