Lawful Development Certificate Drawings in West Hampstead NW6
Fixed-fee, MCIAT-chartered lawful development certificate drawings for West Hampstead (NW6) homeowners — London Borough of Camden validation and local constraints handled from the start.
West Hampstead in NW6 is a dense band of red-brick Victorian and Edwardian terraces and mansion blocks strung along its three stations, with a very high rate of flat conversion. Work here is dominated by rear extensions, loft conversions and the reconfiguration of converted flats, where ownership and access arrangements matter as much as the planning application itself.
Because conservation designations such as West End Green and Priory Road control the characteristic red-brick frontages, we keep original detailing and roof profiles intact and prepare the drawings and supporting statements Camden Council requires, while co-ordinating the party-wall and leasehold issues that flat-conversion sites inevitably raise.


Planning in West Hampstead (NW6): what to know before you apply
No published householder Article 4 direction applies, but conservation-area coverage over key streets governs frontages and rooflines, and the area's heavy flat-conversion pattern makes leasehold and party-wall matters central to most projects.
Typical West Hampstead housing stock
Dense red-brick Victorian and Edwardian terraces and purpose-built mansion blocks line the streets around the three West Hampstead stations. A very high proportion of houses have been converted into flats, giving the area a distinctly sub-divided residential grain.

Lawful Development Certificate Drawings for West Hampstead (NW6) homes: the package and the process
Every lawful development certificate drawings we prepare for an West Hampstead property is drawn to London Borough of Camden’s validation standards and tuned to the NW6 constraints above. Here is what the drawing package covers and how the process runs from first survey to approval.
A Lawful Development Certificate (LDC) is a legal document from your local planning authority confirming that building work, or a use of land, is lawful and does not need planning permission. It is not planning permission itself — it is proof that permission was never required, which matters when a mortgage lender, a solicitor or a future buyer asks for evidence that an extension, loft conversion or outbuilding was built within your permitted development rights. DrawingsDirect prepares the drawings and supporting evidence a London borough needs to issue a certificate, checking first whether your project genuinely qualifies.
There are two certificate routes — one for work you are about to carry out (a proposed LDC) and one for work or a use that already exists (an existing or established-use LDC). Both are assessed against the same permitted development rules that apply to a full planning application, but the process is narrower, usually faster and typically cheaper, because the council is confirming a legal fact rather than exercising planning judgement. We assess your property, extension or use before recommending this route, so you are never sold a certificate application that will not succeed.
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.
