Planning Drawings in Brockley SE4
Fixed-fee, MCIAT-chartered planning drawings for Brockley (SE4) homeowners — London Borough of Lewisham validation and local constraints handled from the start.
Brockley (SE4) in Lewisham is one of south London's largest and best-preserved Victorian suburbs, a hillside of grand semi-detached villas and terraces centred on the Brockley conservation area. Because that conservation area carries an Article 4 direction, the usual permitted-development shortcuts for lofts and extensions mostly don't apply here.
Inside the conservation area the Article 4 direction removes householder permitted development rights, so even modest external changes need a planning application designed to the area's Victorian character. Lewisham's separate small-HMO Article 4 direction adds a further control on conversions. We check exactly where a Brockley property sits before advising on the route.
Planning in Brockley (SE4): what to know before you apply
The Brockley conservation area covers most of SE4 and carries an Article 4 direction that removes householder permitted development rights within it — so loft conversions, dormers and extensions there almost always need a full planning application rather than a Lawful Development Certificate. Lewisham's small-HMO Article 4 direction is a further control on conversions across the area.
Typical Brockley housing stock

Planning Drawings for Brockley (SE4) 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 |
