Hornchurch in RM12 is a green outer-London suburb of spacious interwar semis and some Edwardian homes, where generous gardens make rear and side extensions, loft conversions and outbuildings the mainstay of local projects.

Much of this work can proceed under permitted development, but where a scheme exceeds those limits or sits near the St Andrew's Church conservation area we prepare full drawings to Havering Council's standard for a straightforward approval.

Planning in Hornchurch (RM12): what to know before you apply

There is no published householder Article 4 direction across most of Hornchurch, so many extensions and lofts fall under permitted development; the St Andrew's Church conservation area is the main exception where external changes need closer assessment.

Typical Hornchurch housing stock

Hornchurch is largely made up of spacious interwar semi-detached houses with some Edwardian properties, typically set back with generous gardens. The suburban plots suit rear and side extensions, loft conversions and outbuildings, much of it deliverable under permitted development.

Planning Drawings for Hornchurch (RM12) homes: the package and the process

Every planning drawings we prepare for an Hornchurch property is drawn to London Borough of Havering’s validation standards and tuned to the RM12 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 Hornchurch RM12 — 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 for an extension in Havering?+
Havering has no borough-wide Article 4 direction affecting typical householder permitted development, so its detached and semi-detached homes often keep fuller rights than inner-London terraces — larger rear and single-storey extensions can qualify. Green-belt land toward the east and conservation areas such as Upminster and Emerson Park restrict this. We check your address first and can confirm permitted development with a Lawful Development Certificate.
How does green-belt land affect my Havering project?+
On green-belt properties toward the borough's eastern and northern edges, extensions are assessed against strict limits on disproportionate additions to the original dwelling. It does not rule out an extension, but scale and siting matter and the case must be evidenced carefully. We confirm whether your property is green belt and design a scheme that stays within policy.
Can I build a bigger extension because Havering plots are larger?+
Often, yes. The generous interwar and detached plots across Hornchurch, Emerson Park and Upminster make substantial rear and double-storey extensions viable where a tight terrace could not. The limit is usually policy rather than space. We design to use the plot fully within permitted-development allowances or a well-evidenced full application.
How long does Havering Council take to decide?+
Havering determines most householder applications within the statutory eight-week period once validated; green-belt and conservation cases can involve additional consultation. A complete, correctly scaled submission is the best way to avoid a validation query — we prepare Havering drawings to the council's checklist to keep the application on track.
How much do planning drawings cost in Havering?+
We quote a fixed fee upfront, typically around 30% below an architect's charge for the same council-accepted drawings, with free redraws until Havering approves. Because plots here allow larger schemes, the fee tracks complexity — a single-storey rear differs from a double-storey or a green-belt case — and we confirm it once we understand your plans.
