Planning Permission in Totteridge N20
Fixed-fee, MCIAT-chartered planning permission for Totteridge (N20) homeowners — London Borough of Barnet validation and local constraints handled from the start.
Totteridge (N20) runs along a green ridge of large detached houses, former farmhouses and villas on deep plots with paddocks and mature trees, and that semi-rural grain shapes the generous but carefully judged extensions we draw here.
Because the conservation area has carried Article 4 directions since 1970 that remove PD rights for extensions, roofs, porches and outbuildings, we check the boundary and any Green Belt overlap before advising whether a scheme needs a full application.


Planning in Totteridge (N20): what to know before you apply
Totteridge extensions almost always run as full householder applications to Barnet, since the long-standing Article 4 directions remove the permitted-development route across the conservation area. We prepare a heritage-and-landscape-aware set, checking tree constraints and any Green Belt overlap before submission.
Typical Totteridge housing stock
Large detached houses, former farmhouses and villas set along the ridge of Totteridge Lane and Totteridge Village, on deep plots with paddocks, mature trees and green verges giving the area its semi-rural character.

Planning Permission for Totteridge (N20) homes: the package and the process
Every planning permission we prepare for an Totteridge property is drawn to London Borough of Barnet’s validation standards and tuned to the N20 constraints above. Here is what the drawing package covers and how the process runs from first survey to approval.
Securing planning permission in London means navigating borough-specific design guidance, conservation areas, Article 4 directions and a validation checklist that differs from one council to the next. DrawingsDirect prepares the existing and proposed drawings your local planning authority needs, submits them through the Planning Portal, and manages the application to a decision — for a fixed fee agreed before we start.
Because we are MCIAT-chartered architectural technologists rather than a general architecture practice, you get the same council-accepted drawings and professional accountability at a typically lower fee, with structural coordination handled in-house.
Do I need planning permission for an extension in London?
Many single-storey rear extensions, loft conversions and outbuildings fall under permitted development rights and do not need a full planning application — but London's dense housing stock, conservation areas and Article 4 directions frequently withdraw those rights. Before you pay for a full application, we check your property against the current permitted development thresholds and your borough's local constraints.
Where permitted development applies, we recommend a Lawful Development Certificate instead of full planning — it is faster, cheaper and gives you a legal document confirming the work was lawful. Where a full application is genuinely required, we prepare it properly the first time.
Permitted development vs a full planning application
Permitted development lets you build within defined volumetric limits without committee review. A full householder application is assessed against the borough's local plan for scale, daylight, neighbour impact and design. We advise which route your project qualifies for and why.
Article 4 directions and conservation areas
If your home sits in a conservation area or under an Article 4 direction, permitted development rights are often removed — meaning even modest changes need consent. Each borough page lists the local directions and conservation areas we routinely design around.
How do you apply for planning permission through the London Planning Portal?
We manage the full lifecycle of your submission — survey, drawings, supporting documents and officer liaison — so you never have to decode a validation checklist yourself.
Phase 1 — existing and proposed site surveys
A laser-measured survey captures your property exactly, so existing and proposed drawings match reality millimetre for millimetre.
Phase 2 — technical drawing package
Site location plan, block plan, floor plans, elevations and sections drawn to your borough's scale and formatting requirements, with a design and access statement where needed.
Phase 3 — liaison with the planning officer
We answer the council's queries, negotiate amendments, and redraw free until the decision lands.
