Planning Drawings in Lambeth
Fixed-fee, MCIAT-chartered planning drawings for Lambeth homeowners — London Borough of Lambeth validation and local constraints handled from the start.
Lambeth stretches from the Georgian terraces of Kennington and Stockwell down through the Victorian and Edwardian streets of Brixton, Clapham and Streatham, with mansion blocks and converted flats near the commons and out toward Herne Hill and West Norwood. The side-return-plus-rear extension is the borough's signature householder project, repeated across dense terraced grids, and the London Borough of Lambeth has clear, well-established design expectations for these house types — which a technologist who knows the local pattern can meet first time.
Constraints turn on the exact street. Conservation areas including Clapham Common, Brixton Water Lane, Herne Hill, Stockwell Park, Streatham Lodge and Kennington tighten control over rooflines, materials and front elevations, and can remove permitted development on side-returns and rear works. Lambeth applies an Article 4 direction to HMO conversions from C3 to C4 in designated parts of the borough, with basement development controls in some conservation areas. Many Lambeth homes are converted flats, so ownership, lease and party-wall context — and the freeholder's agreement — often matters as much as the planning route itself.
We draw Lambeth planning applications to the borough's residential extension guidance, checking permitted development eligibility and any conservation-area or flat-conversion constraint for your specific street before design begins, and confirming permitted development with a Lawful Development Certificate where the work qualifies. Where a home is a converted flat we resolve the ownership and shared-structure context first, so the scheme is deliverable and not merely consentable. The fee is fixed and agreed up front, usually around 30% below an architect's fee for the same council-accepted drawings, with free redraws until Lambeth approves. The terraced grids around Clapham and Brixton are party-wall-sensitive, so we prepare submissions to keep them inside the statutory eight-week determination, with a roughly seven-day drawing turnaround.


Planning in Lambeth: what to know before you apply
Lambeth applies an Article 4 direction to HMO conversions in parts of the borough and controls design closely within its conservation areas, particularly around Clapham Common and Brixton. Many Lambeth homes are converted flats, so ownership and shared-structure considerations often matter as much as the planning route — we resolve both before drawing.

What the numbers say about Lambeth planning decisions
These are London Borough of Lambeth’s own reported figures, published by government rather than estimated by us. They are what we design against — a borough that refuses one householder application in five needs a different drawing package from one that refuses one in twenty.

Planning Drawings for Lambeth homes: the package and the process
A planning set is judged as a set, not as individual sheets. Every existing drawing needs its proposed counterpart at the same scale and orientation so the officer can read the change at a glance, each sheet needs its own number, title, scale bar and north point, and the whole package needs to survive being printed at A3 without a dimension becoming illegible.
We draw to the conventions validation teams expect: plans and elevations at 1:100 or 1:50, a location plan at 1:1250 with the site edged red, a block plan at 1:500, and sections cut where the change in level or roof form actually happens rather than where they are easiest to draw.
The drawing list itself changes with the building. A detached house needs four elevations; a mid-terrace needs two plus a section through the party walls to show what is not visible from outside. Getting that list right at the start is what stops a validation officer asking for a sheet three weeks in.
What is included in a planning drawing set?
A council will only validate an application that contains the right drawings at the right scale. Our standard planning set covers everything a London validation team expects.
- Site location plan (1:1250) and block plan (1:500)
- Existing floor plans, elevations and sections
- Proposed floor plans, elevations and sections
- Roof plans where relevant, with heights and materials annotated
- A design and access or heritage statement where the borough requires one
How are planning drawings different from building regulations drawings?
Planning drawings show what the building will look like and how it sits in its context. Building regulations drawings show how it will be built safely — structure, insulation, fire escape and drainage. Most projects need both; our Complete package covers the two together with structural calculations coordinated in-house.
How quickly can you produce planning drawings in London?
After a laser survey, a standard householder set is typically ready within 7 days. We review every drawing against your borough's validation checklist before it reaches a planner's desk, which is why our first-time approval rate sits around 96%.
| Drawing | Typical scale | What it shows |
|---|---|---|
| Site location plan | 1:1250 | The property in its street context, site edged red |
| Block plan | 1:500 | The building's footprint and position in the plot |
| Floor plans (existing & proposed) | 1:100 / 1:50 | Room layout, walls, openings and the proposed changes |
| Elevations (existing & proposed) | 1:100 / 1:50 | Each face of the building and how it changes |
| Sections | 1:100 / 1:50 | A cut through showing heights, levels and roof form |
