Planning Drawings in Coulsdon CR5
Fixed-fee, MCIAT-chartered planning drawings for Coulsdon (CR5) homeowners — Croydon Council validation and local constraints handled from the start.
Coulsdon CR5, and Old Coulsdon in particular, pairs an historic village core around Bradmore Green with streets of interwar 1930s semis, where rear and side extensions and loft conversions are the common ways families extend.
In the Bradmore Green Conservation Area, dormers and other roof enlargements, side extensions, rear extensions over one storey and cladding are not permitted development, so we check whether a property falls inside that boundary before choosing permitted development over a full application.
Planning in Coulsdon (CR5): what to know before you apply
Coulsdon homes outside the conservation area often retain permitted development for rear extensions and lofts, while those inside Bradmore Green usually need full householder applications to Croydon. We confirm the boundary and roof form before advising a route.
Typical Coulsdon housing stock
The heart of Old Coulsdon around Bradmore Green and Grange Park keeps an older village character, wrapped by the interwar and 1930s semi-detached houses that make up much of the wider CR5 stock, most with side and rear scope for extension.

Planning Drawings for Coulsdon (CR5) 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 all-inclusive package covers the two together, with structural calculations from a named, insured engineer drawn onto the same set.
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, so it arrives validated rather than bouncing back on a technicality.
| 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 |
