Change of Use Drawings in Lewisham SE13
Fixed-fee, MCIAT-chartered change of use drawings for Lewisham (SE13) homeowners — London Borough of Lewisham validation and local constraints handled from the start.
Lewisham (SE13) itself runs from the historic Georgian and early-Victorian houses of Belmont Hill down to a fast-regenerating town centre around Lewisham High Street and Loampit Vale. Householder projects on the hill sit in a conservation context, while the town-centre streets are shaped by regeneration and taller development.
The Belmont conservation area is the main householder control, protecting the older houses on and around Belmont Hill, and Lewisham's small-HMO Article 4 direction restricts new conversions across the area. We check a SE13 address against both, and against the town-centre policies, before recommending a route.


Planning in Lewisham (SE13): what to know before you apply
SE13's Belmont conservation area protects the Georgian and early-Victorian houses on Belmont Hill, where roofline and elevation changes are closely controlled, while Lewisham's small-HMO Article 4 direction restricts new small-HMO conversions across the district. Around the town centre, regeneration and tall-building policy set the context rather than householder permitted development.
Typical Lewisham housing stock
Georgian and early-Victorian houses on and around Belmont Hill, Victorian terraces on the streets off Lewisham High Street, and 20th-century and new-build flats through the regenerating town centre.

Change of Use Drawings for Lewisham (SE13) homes: the package and the process
Every change of use drawings we prepare for an Lewisham property is drawn to London Borough of Lewisham’s validation standards and tuned to the SE13 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.
