Lawful Development Certificate Drawings in Thames View IG11
Fixed-fee, MCIAT-chartered lawful development certificate drawings for Thames View (IG11) homeowners — London Borough of Barking and Dagenham validation and local constraints handled from the start.
Thames View (IG11) is a cohesive 1950s London County Council overspill estate, built on former marshland south of Barking town centre as a planned postwar community of low-rise council-built houses and blocks. That open, uniform estate layout — quite distinct from the borough's older terraced streets — is what shapes nearly every householder project here, so an extension has to sit comfortably within a very consistent, planned streetscape.
There is no conservation area covering Thames View — that is a genuine, verified fact, not an omission. Its planning character is shaped instead by the sheer uniformity of the estate layout and by Barking and Dagenham's householder design expectations, which lean on keeping the original postwar rhythm, materials and building lines intact. We treat that estate cohesion, rather than a conservation designation, as the reference point when we design an extension.
Because so many Thames View houses passed into private ownership after Right to Buy, demand for rear extensions, side infills and loft conversions is steady across streets like Bastable Avenue, Maplestead Road and Moore Crescent. We check each property's permitted-development position against Barking and Dagenham's borough-wide controls first, then prepare drawings that either stay within permitted development or are ready to validate as a full householder application.
Planning in Thames View (IG11): what to know before you apply
Because the estate is so uniform, Barking and Dagenham assess extensions on Thames View houses against the consistent postwar street pattern, so matching brick, render and roof form matters more than on a mixed-typology road. There is no conservation area and no estate-specific Article 4 direction, so many houses retain permitted development rights for rear and loft work — but the open estate layout, shared building lines and low-lying former-marshland ground mean spacing, neighbour impact and drainage are the points an application turns on.
Typical Thames View housing stock
Cohesive 1950s council-built houses and low-rise blocks arranged on a planned, open postwar layout, many now privately owned following Right to Buy — which is what drives the steady flow of rear-extension and loft-conversion work across the estate.

Lawful Development Certificate Drawings for Thames View (IG11) 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.
