Catford (SE6) in Lewisham is defined by its consistent Edwardian estates — above all the Culverley Green conservation area and the neighbouring Corbett Estate, whose uniform terraces give the area a strong, coherent character. That consistency is exactly what the planning controls here are designed to protect.

The Culverley Green conservation area carries an Article 4 direction controlling householder alterations, and the wider Corbett Estate streets are assessed for their uniform Edwardian frontages, so dormers, extensions and elevation changes need to respect the established pattern. Lewisham's small-HMO Article 4 direction adds a control on conversions. We design Catford schemes to fit that grain.

Planning in Catford (SE6): what to know before you apply

SE6's Culverley Green conservation area carries an Article 4 direction that controls householder alterations within the Edwardian estate, and the surrounding Corbett Estate is valued for its uniform frontages — so extension and loft designs in Catford are judged closely against the established Edwardian pattern. Lewisham's borough small-HMO Article 4 direction is a further control on conversions.

Planning Permission for Catford (SE6) homes: the package and the process

Every planning permission we prepare for an Catford property is drawn to London Borough of Lewisham’s validation standards and tuned to the SE6 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.

FAQ

Planning Permission in Catford SE6 — FAQs

How long does it take to get planning permission from a London council?+
Householder applications carry a statutory 8-week determination period. We deliver your drawings within about 7 days of survey, so the council clock can start quickly. Lawful Development Certificates usually resolve faster.
What happens if the council refuses?+
Refusals are rare because every drawing is checked against your borough's local plan before submission. If it happens we advise on revisions or handle the appeal — many refusals recover at appeal.
Do you cover my borough?+
Yes — we submit across all 33 London boroughs every week. Each borough has its own page covering local conservation, Article 4 and validation quirks.
Is the fee really fixed?+
Yes. We quote a fixed fee before we start and it does not move, even when the council asks for revisions — those redraws are free.
Do I need planning permission for a side-return extension in Lewisham?+
On the Victorian and Edwardian terraces of Brockley, Forest Hill and Hither Green a single-storey side-return or rear extension can fall within permitted development, so a full application isn't always needed. Conservation areas such as Blackheath, Brockley and Telegraph Hill restrict this. We check your street's designation first and can confirm permitted development with a Lawful Development Certificate where it qualifies.
What does Lewisham's borough-wide HMO Article 4 direction affect?+
Lewisham applies a borough-wide Article 4 direction removing permitted development rights for change of use to an HMO (C3 to C4), so a conversion to a house in multiple occupation needs a full application anywhere in the borough. It doesn't affect a standard family extension or loft, but we confirm whether it applies to your intended use before advising on a route.
Can I convert the loft on my Lewisham terrace?+
Usually, yes. The terraces of Brockley, Forest Hill and Hither Green suit hip-to-gable and dormer loft conversions, which frequently qualify as permitted development within the volume limits. Outside the conservation areas this is often the quickest route. We confirm eligibility against those limits and any designation, then produce the planning and building-regulations drawings.
How long does Lewisham Council take to decide?+
Lewisham determines most householder applications within the statutory eight-week period once validated; conservation cases can attract additional consultation. The dense terraced streets are party-wall-sensitive, so the commonest delay is a drawing query — we prepare submissions to the council's validation checklist to keep them moving.
How much do planning drawings cost in Lewisham?+
We agree a fixed fee before starting, usually around 30% below an architect's fee for the same council-accepted drawings, with free redraws until Lewisham approves. A side-return, a loft and a conservation-area scheme differ in complexity, so we quote once we understand your street and project rather than charging by the hour.
