HMO Conversion Drawings in Willesden NW10
Fixed-fee, MCIAT-chartered hmo conversion drawings for Willesden (NW10) homeowners — London Borough of Brent validation and local constraints handled from the start.
Willesden (NW10) in Brent is a densely built late-Victorian and Edwardian neighbourhood centred on Willesden High Road and Walm Lane, where rear and loft projects on the terraces and bay-fronted houses are the everyday work. The Willesden Green conservation area — extended in 2024 — now reaches beyond the High Road parades to take in Brondesbury Park, Rutland Park Mansions and the Chatsworth Road and Dean Road streets.
Two conservation areas shape the district: Willesden Green in the centre and Kensal Rise to the south around Chamberlayne Road. Brent also runs an Article 4 direction on converting houses to small HMOs, so we confirm whether a Willesden address sits inside a conservation-area boundary — and whether a scheme is a householder extension or a change of use — before recommending a permitted-development or full-application route.
Planning in Willesden (NW10): what to know before you apply
Willesden houses generally retain permitted development rights for rear and loft work, but the Willesden Green and Kensal Rise conservation areas control frontages and rooflines across much of NW10, and Brent's Article 4 direction removes the right to convert a house to a small HMO without permission. We check the conservation-area boundary and the proposed use first, then draw to Brent's residential extensions guidance.
Typical Willesden housing stock
Late-Victorian and Edwardian terraces and bay-fronted houses on the streets around Willesden High Road and Walm Lane, with mansion blocks along the main roads and pockets of interwar and post-war infill toward Harlesden and Kensal.

HMO Conversion Drawings for Willesden (NW10) homes: the package and the process
Every hmo conversion drawings we prepare for an Willesden property is drawn to London Borough of Brent’s validation standards and tuned to the NW10 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.
