Planning Drawings in Collier Row RM5
Fixed-fee, MCIAT-chartered planning drawings for Collier Row (RM5) homeowners — London Borough of Havering validation and local constraints handled from the start.
Collier Row (RM5) took shape as an interwar suburb of Romford, expanding through the 1920s and 1930s across former Essex farmland. It is a planned residential district rather than a historic village core, with predominantly semi-detached housing, so almost every householder project here is an extension or loft on one of those consistent interwar pairs.
There is no conservation area covering Collier Row — that is a genuine, verified fact, not an omission. Its planning character is instead shaped by the uniformity of its interwar suburban roads and by the London Borough of Havering's householder design expectations, which favour keeping the semi-detached rhythm, the gaps between pairs and the original materials intact. We treat that suburban cohesion, rather than a conservation designation, as the reference point when we design an extension.
Demand for rear extensions, two-storey side extensions and hip-to-gable lofts is steady across roads like Mawney Road, Silvermere Avenue and Victoria Avenue, where regular plots and gardens are typical. We check each property's permitted-development position against Havering's borough-wide controls first, then prepare drawings that either stay within permitted development or are ready to validate as a full householder application.
Planning in Collier Row (RM5): what to know before you apply
Because Collier Row's suburban roads repeat so consistently, Havering assess extensions against the established semi-detached pattern, so matching original brick, render and roof form and preserving the gap between pairs matters more than on a mixed-typology road. There is no conservation area and no local Article 4 direction, so many houses retain permitted development rights for rear and loft work — but the finite gardens and shared building lines mean depth, height and neighbour impact are the points a householder application is judged on.
Typical Collier Row housing stock
Predominantly interwar semi-detached houses on planned suburban roads, with postwar and modern infill on regular gardened plots. The consistent pairs and generous front and rear gardens are what makes rear extensions, side extensions and hip-to-gable loft conversions the common projects here.

Planning Drawings for Collier Row (RM5) 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 |
