Fixed-fee, MCIAT-chartered hmo conversion drawings for Brixton Hill (SW2) homeowners — London Borough of Lambeth validation and local constraints handled from the start.
Brixton Hill (SW2) runs up the ridge between Brixton and Streatham Hill in Lambeth, and its Victorian terraces and villas make side-return, rear and loft projects the most common work here. The Rush Common & Brixton Hill conservation area governs frontages and rooflines along much of the hill, so where a property sits relative to that boundary shapes how an extension or loft is designed and assessed.
SW2 also carries an unusual historic control: the Rush Common Act restricts building on the old open land in front of houses on the east side of Brixton Hill, which can affect front additions and boundary work on those plots. We check both the conservation boundary and the Rush Common frontage before recommending a permitted-development or full-application route, and prepare the drawings to Lambeth's residential design and validation standards.


Planning in Brixton Hill (SW2): what to know before you apply
SW2 has no borough-wide householder Article 4 direction, so many Brixton Hill houses retain permitted development rights — but the Rush Common & Brixton Hill conservation area is the exception, and the historic Rush Common Act frontage restriction is a genuine local quirk on the east side of the hill that we check before drawing.

HMO Conversion Drawings for Brixton Hill (SW2) 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 |
