HMO Conversion Drawings in Romford RM1
Fixed-fee, MCIAT-chartered hmo conversion drawings for Romford (RM1) homeowners — London Borough of Havering validation and local constraints handled from the start.
Romford (RM1) is built around one of London's oldest chartered markets, and the Romford Conservation Area protects the Market Place and the ancient crossroads where North Street, South Street and the High Street meet. Work on or near those frontages faces conservation-area control, so we always check where a property sits against the boundary before choosing a route.
Away from the protected core the district is mostly Victorian and Edwardian terraces with inter-war housing behind, and rear and side-return extensions plus loft conversions are the common projects. Havering's householder guidance sets clear expectations for these, and preparing drawings to match is how RM1 schemes clear first time.
Planning in Romford (RM1): what to know before you apply
There is no borough-wide Article 4 direction affecting typical RM1 householder work, so many Romford houses retain permitted development rights for rear and loft projects. The exception is the Romford Conservation Area around Market Place, where frontage, material and shopfront changes are controlled and permitted development is curtailed.
Typical Romford housing stock
A historic market-town core of shops and civic buildings around Market Place, ringed by Victorian and Edwardian terraces and later inter-war housing on the residential streets running off North Street and toward Como Street.

HMO Conversion Drawings for Romford (RM1) homes: the package and the process
Every hmo conversion drawings we prepare for an Romford property is drawn to London Borough of Havering’s validation standards and tuned to the RM1 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.
