Charlton (SE7) keeps a genuine village core around Charlton House and St Luke's church, and most of our work here is rear and side-return extensions or loft conversions on the Victorian and Edwardian terraces that spread out along Charlton Road and Charlton Church Lane.

Homes inside the Charlton Village Conservation Area lose some permitted-development freedoms, and the nearby Rectory Field area carries an Article 4 direction, so we check the exact boundary and designation before advising whether your project is permitted development or a full householder application.

Planning in Charlton (SE7): what to know before you apply

Outside the conservation area many rear extensions and lofts stay within permitted development, but inside Charlton Village or the Rectory Field Article 4 area a full householder application is usually needed. We confirm the designation for your address and prepare drawings to Royal Greenwich standards.

Typical Charlton housing stock

The historic village around Charlton House and St Luke's church keeps Georgian and early-Victorian houses and cottages, giving way to Victorian and Edwardian terraces and inter-war semis on the surrounding slopes.

Lawful Development Certificate Drawings for Charlton (SE7) homes: the package and the process

A certificate application is an evidence exercise. There is no design judgement to win: either the proposal falls inside the permitted development rules or it does not, and the drawings have to prove which. Every limiting dimension — depth, height, volume, distance to boundary — is set out and labelled against the rule it satisfies.

That makes accuracy on the existing drawings decisive. The allowances are measured from the original house as first built, so previous extensions have to be shown and discounted. We draw that history explicitly, because an unevidenced claim about the original footprint is the usual reason a certificate is refused.

The allowance depends on the original house, and building form sets it: volume limits differ for terraced homes against semi-detached and detached ones, and depth allowances differ again. Establishing which category the property falls into is the first step of the evidence, not a detail.

What is a Lawful Development Certificate?

A Lawful Development Certificate is issued under the Town and Country Planning Act and confirms, in writing, that a building project or a use of land is lawful and would not have required planning permission — or, for existing situations, that enough time has passed that the council can no longer take enforcement action. It carries the same legal weight as a planning permission for the purposes of proving lawfulness, and is the document solicitors and lenders look for when unauthorised-looking work shows up in a survey or a title check.

Proposed development vs an existing use — the two certificate types

Which certificate you need depends on whether the work is planned or already done.

Certificate of Lawfulness for Proposed Use or Development (LDCP)

Confirms, before you build, that a specific extension, loft conversion, outbuilding or use falls within your permitted development rights, so no planning application is needed. Useful where you want written certainty before committing to a project — for example ahead of a sale, or where a neighbour has raised a query.

Certificate of Lawfulness for Existing Use or Development (LDCE)

Confirms that work already carried out, or a use already established, is lawful — either because it fell within permitted development at the time, or because it has continued unchallenged for the statutory period (generally four years for a building operation or an unauthorised use as a single dwellinghouse, and ten years for most other unauthorised uses). This is the route most often needed at the point of sale, when a survey flags work with no paper trail.

Why choose an LDC over a full planning application?

Where a project genuinely falls within permitted development, an LDC is usually faster and less expensive than a householder planning application, because the council is confirming a fact rather than weighing design, amenity and neighbour impact. It also produces a cleaner record for the future: a full planning permission can carry conditions that still need discharging, while a certificate is a straightforward confirmation of lawfulness with nothing further to satisfy. The trade-off is scope — an LDC only works where the project is genuinely within permitted development or an established use; it cannot be used to seek permission for something that needs planning judgement.

FAQ

Lawful Development Certificate Drawings in Charlton SE7 — FAQs

How much does a Lawful Development Certificate cost?+
Our LDC drawing and application packages typically start from £950, depending on the complexity of the project and the evidence required. We agree a fixed fee upfront, before any drawing work begins.
How long does an LDC application take to be decided?+
Councils have a statutory eight-week period to determine most LDC applications, similar to a householder planning application. We prepare a complete, evidence-backed package to avoid the delays that come from a council requesting further information.
What happens if the council refuses my LDC application?+
If a certificate is refused, the underlying work is not automatically unlawful — it simply means the council disputes that it falls within permitted development. We assess this risk before you apply, and where a certificate is unlikely to succeed we recommend a full planning application instead.
Do I need an architect for a Lawful Development Certificate?+
No. As an MCIAT-chartered architectural technologist practice, we prepare the same council-accepted drawings and evidence an architect would, typically at a lower fee, and submit via the Planning Portal on your behalf.
Is an LDC the same as building regulations approval?+
No. An LDC only addresses planning lawfulness. Building regulations approval, covering structural safety, fire and insulation standards, is a separate process and is still needed for most building work, even where no planning permission is required.
Do I need planning permission for an extension in Greenwich?+
It depends on the area. The interwar and post-war suburbs toward Eltham and Kidbrooke often retain permitted development rights for rear extensions and lofts, while the historic core around West Greenwich and Blackheath sits within conservation areas where those rights are removed. We check your address against the designations first and can confirm permitted development with a Lawful Development Certificate.
How does the Maritime Greenwich World Heritage Site affect my project?+
Proposals within the World Heritage Site or its buffer zone are assessed against the setting of Maritime Greenwich, where the council protects townscape and long views toward the Royal Observatory. It doesn't rule out an extension, but roof-level and prominent works near the site need careful, context-led design. We confirm whether the setting applies to your address before drawing.
Can I extend a home in Blackheath or Westcombe Park?+
Yes, but these conservation areas carry strong design control over materials, rooflines and front elevations, and sloping sites around Blackheath and the Greenwich hills shape what works. We design context-led drawings that respond to the area's Georgian and Edwardian character and the topography, which is what carries applications to consent here.
How long does the Royal Borough of Greenwich take to decide?+
Greenwich determines most householder applications within the statutory eight-week period once validated; World Heritage Site, conservation and protected-view cases can involve additional consultation. We prepare submissions to the council's validation checklist to avoid the drawing queries that cause most delays.
How much do planning drawings cost in Greenwich?+
We agree a fixed fee before starting, typically around 30% below an architect's fee for the same council-accepted drawings, with free redraws until Greenwich approves. A suburban Eltham extension and a West Greenwich heritage application differ in the evidence required, so we quote once we understand your address and project rather than by the hour.
