Change of Use Drawings in Bexleyheath DA6
Fixed-fee, MCIAT-chartered change of use drawings for Bexleyheath (DA6) homeowners — London Borough of Bexley validation and local constraints handled from the start.
Bexleyheath (DA6) grew up as an inter-war and post-war suburb around the Broadway shopping centre, so most of its housing is 1920s-1950s semi-detached and detached stock where loft conversions and rear extensions are the staple jobs. The bulk of the district sits outside any conservation area, which keeps many householder projects within permitted-development limits.
The exceptions are two nationally important heritage sites: the Red House Lane Conservation Area protecting William Morris's 1859 Arts-and-Crafts house off Upton Road, and Danson Park with its Grade II registered landscape and Georgian Danson House. Work near those boundaries, and to any listed building, is assessed far more tightly than on the surrounding suburban streets.
Planning in Bexleyheath (DA6): what to know before you apply
Most DA6 householder work sits outside any conservation area and can proceed under permitted development, but projects near the Red House Lane Conservation Area or the Danson Park registered landscape are judged on their impact on those settings and usually need a full application. Because Bexley applies Article 4 directions to some but not all of its conservation areas, we confirm on the council's conservation map whether a specific property is caught before assuming permitted-development rights survive.
Typical Bexleyheath housing stock
Bexleyheath is dominated by inter-war and post-war semi-detached and detached suburban housing laid out around the Broadway, punctuated by two national heritage anchors — Philip Webb's red-brick Red House of 1859-60 off Upton Road and the Georgian Danson House in its Grade II registered parkland.

Change of Use Drawings for Bexleyheath (DA6) 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 |
