Change of Use Drawings in Hammersmith & Fulham
Fixed-fee, MCIAT-chartered change of use drawings for Hammersmith & Fulham homeowners — London Borough of Hammersmith & Fulham validation and local constraints handled from the start.
Hammersmith & Fulham is classic terraced West London. Long Victorian and Edwardian grids across Fulham and Shepherd's Bush make side-return and rear extensions, loft conversions and basements the most requested projects, and the council's design expectations for these house types are well established. Around them sit the distinctive red-brick 'Lion houses' of the Peterborough Estate, Edwardian mansion blocks, and newer riverside development along the Thames through Sands End, with Parsons Green, Brook Green, Hammersmith and White City each adding their own grain to the borough.
The controls that matter here are layered. The council operates a basement policy requiring a basement impact assessment for below-ground works, covering structural stability, drainage and groundwater, and Thames-side flood-zone considerations apply near the river. Strong conservation control runs across Bishops Park, Peterborough Estate, Brackenbury, Ravenscourt Park, Bradmore and Crabtree, and Article 4 directions remove permitted development for HMO conversions and, in conservation areas, some basement and frontage works. We confirm exactly which of these apply to your exact address before drawing.
We draw Hammersmith & Fulham planning applications to the borough's residential extension and basement guidance, coordinating structural calculations in-house so party-wall-sensitive terraces and below-ground schemes are handled cleanly and are complete when submitted. On the dense grids we check permitted development first and confirm it with a Lawful Development Certificate where a side-return or rear extension qualifies, and on the Peterborough Estate we design to the 'Lion houses' character. The fee is fixed and agreed up front, typically around 30% below an architect's charge for the same council-accepted drawings, with free redraws until the council approves. Most householder applications are decided within the statutory eight-week period once validated, so we submit validation-first.

Change of Use Drawings for Hammersmith & Fulham homes: the package and the process
A change of use application is decided on what the building is, what it becomes, and what that changes. The drawings show the existing use class layout and the proposed one at the same scale, with a floor area schedule for each so the officer can see exactly what is moving between uses.
The supporting drawings usually matter as much as the plans. Access, parking, servicing arrangements, refuse storage and any external alteration all get drawn, because the objections to a change of use are rarely about the internal layout — they are about what the new use does to the street.
The building's form limits what it can honestly become. A ground-floor unit with its own frontage converts to residential more readily than upper floors reached through a shared entrance, and a deep plan with windows on one elevation only will struggle to give a habitable room adequate light whatever the policy position.
What counts as a material change of use?
Not every change in how a building is used needs planning permission — only a 'material' change, one significant enough to affect the character of the use of the land. Converting a single dwellinghouse into two or more flats is always material. Adding paying lodgers within a single household usually is not, until the household tips over into a small House in Multiple Occupation. We assess whether your proposed change crosses that threshold before recommending a route.
The Use Classes Order: C3, C4, E and sui generis
The Use Classes Order groups uses so planners, and permitted development rules, can treat similar activities consistently.
C3 — Dwellinghouses
The class covering a single household living as a single unit, including up to two people living together as a single household who are not related. Most family homes and self-contained flats fall here.
C4 — Houses in multiple occupation (small)
Covers a shared house or flat occupied by three to six unrelated people sharing basic amenities such as a kitchen or bathroom. Moving from C3 to C4 is a change of use, though it is often permitted development unless your borough has removed that right.
Class E — Commercial, business and service
A wide class combining shops, offices, gyms, cafes and other business uses that can change between each other without planning permission, but changing from Class E to residential use is a material change requiring the prior-approval or full planning route.
Sui generis
Uses that do not fit any class, including large HMOs of seven or more unrelated occupants, betting shops and drinking establishments. A change of use to or from a sui generis use normally needs planning permission.
Do I need full planning permission or can I use prior approval?
Some changes of use are permitted development subject to a prior-approval application rather than full planning permission — the best-known example is Class MA, which allows certain Class E commercial premises to become residential (C3) subject to the council assessing specific matters such as flooding, contamination and noise, without a full application. Other changes, including most conversions of a house into self-contained flats, fall outside any prior-approval route and need full householder or full planning permission. We identify which route applies to your building before drawing anything.
| Route | When it applies | Typical package | Fee from |
|---|---|---|---|
| Prior approval (Class MA) | Class E commercial to residential, meeting the criteria | Prior-approval drawings and statement | £1,200 |
| Full planning permission | Conversion into flats, HMO or use outside prior approval | Planning + building regs | £1,600–£2,400 |
| No application needed | Use falls within an existing permitted class change | Drawings for record purposes only | £450 |
