Kentish Town (NW5) is predominantly Victorian, with two conservation areas — Dartmouth Park on the rising ground to the north and Inkerman in the streets off Kentish Town Road — and Camden's Article 4 layer over the top. It is a district where the difference between one street and the next genuinely changes the route to consent.

Camden's Basements direction removes permitted development rights for basement works throughout, so lower-ground schemes need a full application. The Class E to C3 direction, in its outside-the-CAZ form, removes the permitted commercial-to-residential change here — which matters along Kentish Town Road and Fortess Road, where the shop-to-flat conversion is a common project and now needs planning rather than prior approval. In the Dartmouth Park and Inkerman conservation areas, frontages and rooflines are controlled, and the rise toward Dartmouth Park Hill means rear extension levels and overlooking are assessed against the slope. We check the boundaries and the Article 4 position for an NW5 address before drawing to Camden's guidance.

Planning in Kentish Town (NW5): what to know before you apply

NW5 falls under Camden's Basements Article 4 direction, removing permitted development rights for basement works, and the outside-CAZ Class E to C3 direction, which removes the permitted commercial-to-residential change — so shop-to-flat conversions along Kentish Town Road and Fortess Road need full planning applications rather than prior approval. The Dartmouth Park and Inkerman conservation areas control frontages and rooflines, and the rising ground toward Dartmouth Park Hill brings level and overlooking assessments into rear extension design.

Typical Kentish Town housing stock

Victorian terraces through the centre and along Fortess Road, larger Victorian semi-detached and terraced houses climbing Dartmouth Park Hill, and a substantial share of the stock converted to flats.

Lawful Development Certificate Drawings for Kentish Town (NW5) 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 Kentish Town NW5 — 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 a rear extension in Camden?+
Frequently, yes. Much of Camden sits within a conservation area or is listed, and near-borough-wide conservation coverage removes permitted development for many external works. On unlisted homes outside a conservation area a rear extension may still qualify, but in Hampstead, Belsize Park and Primrose Hill a full application is usually needed. We confirm the exact constraints for your address before drawing.
What is a Basement Impact Assessment and will I need one in Camden?+
Camden operates one of the most rigorous basement policies in London. Schemes involving a basement or lower-ground extension generally require a Basement Impact Assessment addressing structural stability, drainage and groundwater. If you are considering below-ground space we flag the requirement early and coordinate the assessment so the application is complete when it is submitted.
Can I make changes to a listed building in Camden?+
Often, but listed-building consent is usually required alongside — or instead of — planning permission, and internal as well as external changes can be controlled. Camden has a high density of listed buildings in Hampstead, Bloomsbury and Fitzrovia. We screen listing status for your address first and prepare the heritage-led drawings and justification the council expects.
How long does Camden take to decide an application?+
Camden determines most householder applications within the statutory eight-week period once validated; basement, conservation and listed-building cases can involve additional consultation. We prepare Camden submissions to the council's validation and design standards to avoid the drawing queries that cause most delays.
How much do planning drawings cost in Camden?+
We agree a fixed fee before we start, typically around 30% below an architect's fee for the same council-accepted drawings, with free redraws until Camden approves. A conservation-area rear extension, a basement and a listed-building scheme differ in the evidence required, so we quote once we have seen your project rather than by the hour.
