Planning Drawings in Mill Hill NW7
Fixed-fee, MCIAT-chartered planning drawings for Mill Hill (NW7) homeowners — London Borough of Barnet validation and local constraints handled from the start.
Mill Hill (NW7) in Barnet is a semi-rural conservation village of brick and weatherboard cottages along The Ridgeway, set amid green-belt countryside, where projects lean towards sympathetic rear extensions and considered loft conversions.
Because Article 4(2) directions cover much of The Ridgeway and the cluster around The Forge, works that are normally permitted development — enlargements, roof alterations, porches and outbuildings — need a planning application, so we confirm your address against the Article 4 area before advising a route.
Planning in Mill Hill (NW7): what to know before you apply
Within the Article 4(2) parts of Mill Hill, house extensions, roof changes, porches and outbuildings all require a full planning application, and green-belt land nearby is heavily constrained. Elsewhere in NW7, standard permitted-development and lawful-development-certificate routes generally still apply.
Typical Mill Hill housing stock
Around 260 houses of brick and weatherboard cottages typical of rural Middlesex, interspersed with institutional buildings and set within green-belt countryside from Burtonhole Lane to Marsh Lane.

Planning Drawings for Mill Hill (NW7) 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 |
