HMO Conversion Drawings in Peckham SE15
Fixed-fee, MCIAT-chartered hmo conversion drawings for Peckham (SE15) homeowners — London Borough of Southwark validation and local constraints handled from the start.
Peckham (SE15) in Southwark centres on the busy Rye Lane shopping street but is surrounded by genuinely fine housing — most notably the complete early-Victorian terrace of Holly Grove and the well-kept Bellenden Road streets. Rear and loft projects are common on the Victorian terraces, while the town-centre streets carry a different, retail-focused set of controls.
The Holly Grove and Rye Lane Peckham conservation areas are the defining designations here, and Southwark's Article 4 directions in SE15 largely govern the major town centre and protected shopping frontages rather than householder work. We establish which context a Peckham property sits in before drawing.
Planning in Peckham (SE15): what to know before you apply
Southwark's SE15 Article 4 directions mainly cover Peckham's major town centre and protected shopping frontages rather than household extensions, so many Peckham terraces retain permitted development rights — but the Holly Grove and Rye Lane Peckham conservation areas closely control elevations and rooflines within their boundaries, and the Peckham Rye frontages add open-space and tree considerations.
Typical Peckham housing stock
Fine early-Victorian terraces around Holly Grove and the Bellenden Road renewal streets, denser late-Victorian terraces toward Peckham Rye, and post-war estates north of the town centre.

HMO Conversion Drawings for Peckham (SE15) homes: the package and the process
An HMO scheme is drawn against a schedule. Every bedroom is dimensioned with its usable floor area stated, shared kitchen and bathroom provision is counted against the number of occupants, and the layout has to hold up against the space standards the licensing team applies.
The fire strategy is drawn, not described: protected escape route, fire doors and their ratings, alarm coverage by room, and compartmentation between floors. Licensing and building control assess the same drawing set from different angles, so it has to satisfy both without contradiction.
Room count is a function of the existing plan. A large semi or detached house with generous rooms can meet the space standards without subdivision, while a narrow terrace usually cannot reach the same occupancy without creating rooms that fall below the minimum floor area.
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.
Mandatory and additional HMO licensing — what's required?
Most HMOs need a licence from the council, separate from any planning permission. A licence application typically has to demonstrate that the property meets fire safety, amenity and space standards, that gas and electrical installations are safety-certified, and that the landlord or managing agent is a fit and proper person to hold it.
Mandatory licensing
Applies to any HMO of five or more occupants forming two or more households, regardless of the number of storeys — a national requirement in every London borough.
Additional licensing
Many boroughs extend licensing to smaller HMOs, typically three or four occupants, across all or part of their area. We check the current scheme for your borough before you apply, since schemes and boundaries change.
| 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 |
