Loft Conversion Drawings in Barnet | From £1,225

No Article 4 Direction covers Barnet, which keeps the Barnet permitted-development route open on unlisted houses. What defines Barnet is that it is Georgian and Victorian high street, 1930s residential, and design decisions here answer to that rather than to a pattern book. Conservation status changes the Barnet route entirely — Mill Hill being the usual case among the 20 designations in Barnet. We confirm the EN5 designation at survey rather than assuming it.

The Barnet Article 4 position is established at survey, before design. Everything on a Barnet scheme is measured from the georgian fragments outward. The borough policy layer over every EN5 address is set out on Barnet planning. The Barnet survey then carries into house extension drawings in Barnet if the project runs on to construction.

Before Barnet Council determines anything, London Borough of Barnet has to validate the Barnet submission — one to two weeks, longer if a plan is missing. Nothing is drawn for a EN5 address until the existing building is measured.

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 EN5 case and respond to officer queries during the period. A Barnet pack that misses a scale bar is a pack London Borough of Barnet will reject — ours do not.

Comments on a Barnet application are visible on the London Borough of Barnet portal. We photograph the Barnet property alongside the measurements for the record.

Shared walls are the norm in Barnet; the notice period is not optional. Once consent is granted, architectural drawings follows for the EN5 property.

Barnet is characterised by georgian fragments, 1930s semi-detached, concentrated across EN5 in the Barnet / Arkley area. On Barnet plots, structure follows the georgian fragments that is already there. On the Barnet stock specifically: georgian roofs here are shallow and often behind a parapet, so the usable volume comes from a rear dormer set below the ridge rather than from the front slope. On a Barnet terrace it governs the rear opening width. Because Barnet rows are consistent, the proposed elevation is drawn with neighbours on it.

Lower-ground schemes in Barnet answer to neighbours and groundwater. If a Barnet project extends into planning permission for EN5 properties or building regulations drawings, the survey is already done.

What the Barnet drawing pack contains

• existing roof plan and section for the Barnet property
• proposed dormer elevations
• volume calculation sheet
• staircase and head-height sections
• structural steel layout

MCIAT charter sits behind every Barnet submission we make, and the same person who surveys the property signs the drawings off. Not every Barnet scheme is clear-cut. Where Mill Hill or the Barnet High Street setting is in play, Barnet Council pre-application advice comes before the EN5 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.

The first step for a Barnet owner is a measured survey, not a design. This Barnet page was reviewed in August 2026.
