HMO Conversion Drawings in Custom House E16
Fixed-fee, MCIAT-chartered hmo conversion drawings for Custom House (E16) homeowners — London Borough of Newham validation and local constraints handled from the start.
Custom House (E16) grew as Victorian dock-worker housing around the Royal Victoria Dock, which opened in 1855, and now sits inside the Royal Docks regeneration and Enterprise Zone. Surviving and postwar-rebuilt terraces sit alongside major new-build development around the ExCeL and the Elizabeth line, so householder work here is largely extensions and lofts on the terraced houses that line the residential streets.
There is no conservation area covering the Custom House part of E16 — that is a genuine, verified fact, not an omission. Its planning character is instead shaped by the working dockside terraced grain and the surrounding regeneration, and by the London Borough of Newham's householder design expectations, which lean on keeping original building lines, materials and roof continuity intact. We treat that terraced character, rather than a conservation designation, as the reference point when we design an extension.
Demand for rear extensions and loft conversions runs steadily across residential streets like Tollgate Road, Rogers Road and Chadwin Road, where compact terraced houses sit on modest plots. We check each property's permitted-development position against Newham's borough-wide controls first — and any surface-water drainage points given the low-lying dockside land — then prepare drawings that either stay within permitted development or are ready to validate as a full householder application.
Planning in Custom House (E16): what to know before you apply
Because Custom House is a dockside mix of surviving and rebuilt terraces set within the Royal Docks regeneration area, Newham assess extensions against the prevailing rhythm and building line of the individual residential street, so matching original brick, roof continuity and neighbour relationships matters alongside the numbers. There is no conservation area and no local Article 4 direction in the Custom House part of E16, so many terraced houses retain permitted development rights for rear and loft work — but compact plots, shared party walls and low-lying land mean depth, height, neighbour impact and drainage are the points a householder application is judged on.
Typical Custom House housing stock
A mix of surviving and postwar-rebuilt terraced housing with substantial new-build apartments across the Royal Docks regeneration area. It is the terraced houses on the residential streets, rather than the apartment blocks, that generate most of the rear-extension and loft-conversion work here.

HMO Conversion Drawings for Custom House (E16) homes: the package and the process
Every hmo conversion drawings we prepare for an Custom House property is drawn to London Borough of Newham’s validation standards and tuned to the E16 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.
| 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 |
