Fixed-fee, MCIAT-chartered hmo conversion drawings for Thames View (IG11) homeowners — London Borough of Barking and Dagenham validation and local constraints handled from the start.
Thames View (IG11) is a cohesive 1950s London County Council overspill estate, built on former marshland south of Barking town centre as a planned postwar community of low-rise council-built houses and blocks. That open, uniform estate layout — quite distinct from the borough's older terraced streets — is what shapes nearly every householder project here, so an extension has to sit comfortably within a very consistent, planned streetscape.
There is no conservation area covering Thames View — that is a genuine, verified fact, not an omission. Its planning character is shaped instead by the sheer uniformity of the estate layout and by Barking and Dagenham's householder design expectations, which lean on keeping the original postwar rhythm, materials and building lines intact. We treat that estate cohesion, rather than a conservation designation, as the reference point when we design an extension.
Because so many Thames View houses passed into private ownership after Right to Buy, demand for rear extensions, side infills and loft conversions is steady across streets like Bastable Avenue, Maplestead Road and Moore Crescent. We check each property's permitted-development position against Barking and Dagenham's borough-wide controls first, then prepare drawings that either stay within permitted development or are ready to validate as a full householder application.


Planning in Thames View (IG11): what to know before you apply
Because the estate is so uniform, Barking and Dagenham assess extensions on Thames View houses against the consistent postwar street pattern, so matching brick, render and roof form matters more than on a mixed-typology road. There is no conservation area and no estate-specific Article 4 direction, so many houses retain permitted development rights for rear and loft work — but the open estate layout, shared building lines and low-lying former-marshland ground mean spacing, neighbour impact and drainage are the points an application turns on.
Typical Thames View housing stock
Cohesive 1950s council-built houses and low-rise blocks arranged on a planned, open postwar layout, many now privately owned following Right to Buy — which is what drives the steady flow of rear-extension and loft-conversion work across the estate.

HMO Conversion Drawings for Thames View (IG11) 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 |
