EC1N · Hatton Garden
EC1N is Hatton Garden and the streets around Leather Lane: narrow historic plots, jewellery workshops and showrooms at street level, and later commercial infill running down to the Camden/City of London boundary. It is a working trade district first — homes here are upper-floor flats and warehouse conversions, not houses. The historic core sits under conservation-area designation with listed buildings among the stock, so shopfronts, windows and roof plant all need consent. Flats have no permitted development rights, and Camden's Article 4 directions covering basements and Class E (commercial) to residential conversion apply in this part of the borough.

Constraint context · Camden
Real · planning.data.gov.ukCamden has 40 designated conservation areas and 20 Article 4 areas. A district is too coarse to say which apply to your house — postcode districts span many streets and EC1N crosses 2 boroughs.

Is EC1N in a conservation area?
Partly — and which part matters. A postcode district is never uniformly designated: EC1N contains 23 conservation areas within 1km of its centre, and whether your own property sits inside one decides whether permitted development survives. The centre point of EC1N itself falls inside Hatton Garden.

Does an Article 4 direction apply in EC1N?
Yes — EC1N has 4 Article 4 directions mapped within 1km of its centre. An Article 4 direction withdraws specific permitted-development rights on the streets it covers, which is the most common reason a project that looks like permitted development turns out to need a full application. The centre point of EC1N falls inside Basements.

Do you need planning permission in EC1N?
Three routes exist, and which one you are on is decided by your address, not your postcode district:
| Permitted development — no application. The work stays inside the GPDO limits and no designation removes them. A Lawful Development Certificate is cheap proof for a future buyer. | No permission |
| Prior approval — the larger single-storey rear extension route, with neighbour consultation. Not available on designated land. | 42 days |
| Full householder application — required once a designation removes your permitted-development right, or the scheme exceeds the limits. | 8 weeks |
EC1N contains mapped conservation-area or Article 4 geometry, so a meaningful share of its streets will have lost some permitted-development rights — which pushes those properties onto the full-application route. Whether yours is one of them is an address-level question, not a district-level one.
What does planning permission cost in EC1N?
| Householder planning application | £548 (from 1 April 2026) |
| Lawful Development Certificate — proposed works | £274 (half the application fee) |
| Lawful Development Certificate — existing works | £548 (the full application fee) |
| Listed building consent | No fee |
| Resubmission after a refusal | Free once, within 12 months of the decision |
National statutory figures for England — councils do not set them, so they are the same in every borough. Planning fees re-index every 1 April; confirm the current amount on the Planning Portal fee calculator before you apply. These are the council's fees only — drawings, surveys and any specialist reports are separate.
How long does it take?
| Householder application — statutory target | 8 weeks |
| Householder application — in practice | 8–12 weeks |
| Prior approval (larger home extension) | 42 days |
| Lawful Development Certificate | 8 weeks |
| Householder appeal — deadline to lodge | 12 weeks from the decision date |
| Householder appeal — typical decision | Around 18 weeks |
What if it's refused?
A refusal is a decision notice with reasons attached, and those reasons are a roadmap. Most homeowners in Camden — as anywhere in England — are better served by amending the scheme and using the free resubmission than by appealing: you get one further application on the same site within 12 months without paying again.
| Who can appeal | The applicant only — not neighbours |
| Fee to appeal | None — you bear your own costs |
| Procedure | Written representations for most householder appeals |
| Success rate | Roughly a third — about 36% of householder appeals allowed in 2025/26 |
Appeals go to the Planning Inspectorate, an independent national body. How to read a refusal and choose your route →
