Change of Use Drawings in Hayes BR2
Fixed-fee, MCIAT-chartered change of use drawings for Hayes (BR2) homeowners — London Borough of Bromley validation and local constraints handled from the start.
Hayes (BR2) is a green, low-density corner of the borough with roomy interwar detached and semi-detached homes, plus older village-core properties near Hayes station. The space on these plots lends itself to large rear extensions, two-storey side additions, garden rooms and loft conversions, most handled through Bromley's standard householder route.
The historic Hayes Village conservation area and the surrounding commons give the neighbourhood its identity and bring tighter control on materials, roofscape and anything affecting the open green setting. We design extensions that keep the generous plot gaps and building line intact and check tree protection near the commons, so schemes meet Bromley Council's conservation and amenity standards.
Planning in Hayes (BR2): what to know before you apply
No published householder Article 4 direction in Hayes, so most work runs under permitted development or a standard Bromley householder application. Properties within the Hayes Village conservation area have reduced permitted-development rights, and plots near the commons face added scrutiny on trees, footprint and the protected green outlook.
Typical Hayes housing stock
Hayes (BR2) is a leafy outer south-east suburb of generous interwar detached and semi-detached houses on wide plots, with older Victorian and cottage-style properties clustered around the historic village. Large gardens backing onto or near Hayes and Keston Commons make substantial rear and two-storey side extensions common.

Change of Use Drawings for Hayes (BR2) homes: the package and the process
Every change of use drawings we prepare for an Hayes property is drawn to London Borough of Bromley’s validation standards and tuned to the BR2 constraints above. Here is what the drawing package covers and how the process runs from first survey to approval.
A change of use — converting a house into flats, a shop into a flat, or adding a lodger room that tips a home into a small HMO — is governed by the Use Classes Order, which groups land and buildings into classes such as C3 (dwellinghouses), C4 (small shared houses) and E (commercial, business and service uses), plus a handful of uses that sit outside any class, known as sui generis. Whether you need a full planning application, a prior-approval notification, or nothing at all depends on which classes the 'before' and 'after' uses fall into, and whether your permitted development rights have been restricted locally.
DrawingsDirect prepares the drawings and supporting information a London borough needs to assess a change of use — existing and proposed floor plans, a use and amenity statement, and where relevant a parking and refuse strategy — and advises which route applies before you commit to an application. We cover conversions into flats, commercial-to-residential schemes under the prior-approval Class MA route, and other changes of use across all 33 London boroughs.
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.
