Planning Drawings in Sidcup DA14
Fixed-fee, MCIAT-chartered planning drawings for Sidcup (DA14) homeowners — London Borough of Bexley validation and local constraints handled from the start.
Sidcup's DA14 streets run from the 1930s semis of the Cray valley to the historic core of Foots Cray village, and most of our work here is rear kitchen extensions and loft conversions that add space to those bay-fronted family homes without losing garden depth.
If your home sits inside the Foots Cray Conservation Area the permitted-development shortcuts narrow, so we always confirm the boundary line first and then advise whether a project runs under permitted development or needs a full householder planning application to Bexley.
Planning in Sidcup (DA14): what to know before you apply
Most DA14 extensions and lofts outside the conservation area proceed under permitted development or a lawful development certificate. Inside the Foots Cray Conservation Area, or where a home backs onto Foots Cray Meadows or carries protected trees, a full householder planning application to Bexley is the safer route. We check the boundary and tree constraints before recommending either path.
Typical Sidcup housing stock
DA14 is dominated by 1930s bay-fronted semis and terraces along the Cray valley, wrapped around the older historic core of Foots Cray village where Victorian and Georgian buildings survive on the High Street. Larger detached and inter-war housing sits on the roads backing onto Foots Cray Meadows.

Planning Drawings for Sidcup (DA14) 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 |
