Planning Permission in Lewisham SE13
Fixed-fee, MCIAT-chartered planning permission 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.

Planning Permission for Lewisham (SE13) homes: the package and the process
Every planning permission 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.
Securing planning permission in London means navigating borough-specific design guidance, conservation areas, Article 4 directions and a validation checklist that differs from one council to the next. DrawingsDirect prepares the existing and proposed drawings your local planning authority needs, submits them through the Planning Portal, and manages the application to a decision — for a fixed fee agreed before we start.
Because we are MCIAT-chartered architectural technologists rather than a general architecture practice, you get the same council-accepted drawings and professional accountability at a typically lower fee, with structural coordination handled in-house.
Do I need planning permission for an extension in London?
Many single-storey rear extensions, loft conversions and outbuildings fall under permitted development rights and do not need a full planning application — but London's dense housing stock, conservation areas and Article 4 directions frequently withdraw those rights. Before you pay for a full application, we check your property against the current permitted development thresholds and your borough's local constraints.
Where permitted development applies, we recommend a Lawful Development Certificate instead of full planning — it is faster, cheaper and gives you a legal document confirming the work was lawful. Where a full application is genuinely required, we prepare it properly the first time.
Permitted development vs a full planning application
Permitted development lets you build within defined volumetric limits without committee review. A full householder application is assessed against the borough's local plan for scale, daylight, neighbour impact and design. We advise which route your project qualifies for and why.
Article 4 directions and conservation areas
If your home sits in a conservation area or under an Article 4 direction, permitted development rights are often removed — meaning even modest changes need consent. Each borough page lists the local directions and conservation areas we routinely design around.
How do you apply for planning permission through the London Planning Portal?
We manage the full lifecycle of your submission — survey, drawings, supporting documents and officer liaison — so you never have to decode a validation checklist yourself.
Phase 1 — existing and proposed site surveys
A laser-measured survey captures your property exactly, so existing and proposed drawings match reality millimetre for millimetre.
Phase 2 — technical drawing package
Site location plan, block plan, floor plans, elevations and sections drawn to your borough's scale and formatting requirements, with a design and access statement where needed.
Phase 3 — liaison with the planning officer
We answer the council's queries, negotiate amendments, and redraw free until the decision lands.
