House Extension Drawings in Collier Row |

No Article 4 Direction covers Havering, which keeps the Collier Row permitted-development route open on unlisted houses. The character of Collier Row is the yardstick a Havering Council officer measures a scheme against: 1930s semi-detached, post-war. Of the 15 conservation areas Havering designates, Romford Market and Upminster are the ones that most often change how a Collier Row project is routed. That check comes before anything else on a Collier Row job.

That check — Article 4 directions against the Collier Row property — happens on day one. What the Collier Row building allows is established first; what Havering Council allows, second. The borough policy layer over every RM5 address is set out on Havering planning. The Collier Row survey then carries into loft conversion drawings in Collier Row if the project runs on to construction.

The RM5 bottleneck is validation. London Borough of Havering needs one to two weeks, and a missing drawing resets it. A surveyor measures the Collier Row property before any RM5 design begins.

Statutory periods: 8 weeks from validation for a householder application, 13 weeks for a major scheme, 6 weeks for prior approval with a 21 days neighbour consultation, and 5 weeks for a full plans building control submission. A party structure notice requires one month notice and two months where excavation is involved.

We monitor the RM5 case and respond to officer queries during the period. Nothing leaves for a Collier Row address until it matches the local validation checklist.

On Collier Row terraces the objection to expect is loss of light to a rear window. The Collier Row survey records every opening, level change and structural wall.

Serve party wall notices early where RM5 neighbours share a flank wall — on Collier Row terraces they nearly always do. Once consent is granted, architectural drawings follows for the RM5 property.

Collier Row is characterised by 1930s semi-detached, concentrated across RM5 in the Collier Row area. Across RM5 the 1930s semi-detached repeats often enough to be predictable, once it has been measured properly. On RM5 plots specifically, 1930s semis here have the deepest rear gardens in the area, which is why the 6 m and 8 m larger-home prior approval route gets used so often. On Havering stock it changes the party wall position. A Collier Row proposal that breaks the prevailing eaves line invites a refusal.

A RM5 dig turns on engineering more than on policy. Because the Collier Row survey is drawn properly once, planning permission for RM5 properties and building regulations drawings build on it rather than starting again.

What the Collier Row drawing pack contains

What we hand over for a Collier Row property:

• existing and proposed ground-floor plans for the Collier Row property
• proposed rear elevation
• long section through the extension
• site and block plans
• party wall position drawing

Local landmarks that shape a Collier Row application

• Chigwell Row — roof profiles that set the ridge datum Havering Council measures a Chigwell Row dormer against.
• Rise Park — shared flank walls, so Rise Park party structure notices go out before work starts.
• Collier Row Road — height and massing nearby are argued against this frontage.

Surveyors travel to RM5 addresses from the studio; the nearest stations are Hainault, Newbury Park, Romford. Appointments are booked in Collier Row on weekdays and Saturdays, and the measured survey of a standard 1930s semi-detached takes two to three hours.

The technologist drawing your Collier Row scheme is MCIAT chartered — the professional body for technical design and building-regulations competence. Not every Collier Row scheme is clear-cut. Where Romford Market or the Collier Row Road setting is in play, Havering Council pre-application advice comes before the RM5 submission.

Drawings are produced by chartered members of the Chartered Institute of Architectural Technologists (MCIAT), the professional body for technical design and building-regulations competence. First-time approval across our London caseload is 98%. Statutory fees shown are those in force in England in 2026 under the Town and Country Planning (Fees for Applications) Regulations. Confirm your local authority at gov.uk and submission requirements on the Planning Portal. Studio: 71–75 Shelton Street, London WC2H 9JQ.
