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.

Council: London Borough of Havering
Postcode district: RM5
Planning portal: View the Havering planning portal
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.
Article 4: No area-specific Article 4 direction is published for Collier Row; the London Borough of Havering's borough-wide permitted-development controls and householder design guidance still apply.

Local constraints: Consistent interwar semi-detached street pattern, so front-elevation changes, roof forms and the gap between pairs are assessed against a cohesive suburban rhythm rather than a one-off houseHavering's borough-wide permitted-development limits and householder design guidance govern extension depth, height and coverage — no local Article 4 direction narrows them further in Collier RowMatching original facing brick, render, tile-hanging and roof tiles so a rear or side addition reads as part of the original interwar pair rather than an obvious bolt-onThe characteristic gap between semi-detached pairs, which the council protects so streets do not close up — this shapes how wide a two-storey side extension can be and whether it must be set back and set downRegular but finite plot and garden sizes, which constrain how deep a single-storey rear extension can go before it needs a full householder applicationShared party walls and building lines between paired houses, making party-wall relationships, overshadowing and neighbour amenity relevant to what gets approved

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.

Planning Drawings for Collier Row (RM5) homes: the package and the process

Every planning drawings we prepare for an Collier Row property is drawn to London Borough of Havering’s validation standards and tuned to the RM5 constraints above. Here is what the drawing package covers and how the process runs from first survey to approval.

Planning drawings are the scale drawings a London council uses to judge your application: existing and proposed floor plans, elevations, sections and site plans that show the design, scale and neighbour impact of your project. DrawingsDirect produces complete, validation-ready planning drawing sets for extensions, lofts and conversions across London.

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.

FAQ

Planning Drawings in Collier Row RM5 — FAQs

What scale should London planning drawings be?+

Site location plans are 1:1250, block plans 1:500, and floor plans, elevations and sections are typically 1:100 or 1:50. We format every drawing to your specific borough's requirements.

Do I need an architect to produce planning drawings?+

No. MCIAT-chartered architectural technologists produce the same council-accepted planning drawings with the same professional accountability, and councils assess the drawings, not the author's job title.

How many revisions are included in the fee?+

All of them. The fee is fixed and we redraw free until your council approves — revisions requested by a planning officer never cost you extra.

Can you draw from my existing plans?+

We can work from existing measured drawings, but for accuracy we usually carry out a laser survey so the proposed set matches your property exactly.

Do planning drawings guarantee approval?+

No drawing can guarantee a decision, but drawing to the local plan and validation checklist maximises your odds — and we redraw free until approval.

Do I need planning permission to extend a house in Collier Row?+

Not always. Many Collier Row semis retain permitted development rights, so a modest single-storey rear extension or a hip-to-gable loft conversion can often proceed without a full planning application. Because the plots are regular but finite and the gap between pairs is protected, we check your property's size limits and building lines against Havering's controls first, and prepare a full householder application where the project goes beyond permitted development — as a two-storey side extension often will.

Is Collier Row in a conservation area?+

No. There is no conservation area covering Collier Row. Its planning character is shaped instead by its uniform interwar semi-detached suburban roads and Havering's householder design expectations, which favour keeping the semi-detached rhythm, the gaps between pairs and the original materials intact when you extend.

How much do planning and building-regulation drawings cost for a Collier Row extension?+

We work to fixed fees agreed before we start, with a typical turnaround of around seven days for a standard rear extension, side extension or loft on a Collier Row semi. As a chartered architectural technologist practice we produce the same council-accepted planning and building-regulation drawings as an architect, usually for a lower fee, and include free redraws until your application is approved.
