Double Storey Extension Drawings in Hadley Wood EN4
Fixed-fee, MCIAT-chartered double storey extension drawings for Hadley Wood (EN4) homeowners — London Borough of Enfield validation and local constraints handled from the start.
Hadley Wood sits in the far north-west corner of EN4, an Enfield railway suburb of detached and semi-detached red-brick houses on wide, tree-lined plots. Owners here usually want a rear or kitchen extension or a loft conversion that respects the generous spacing and original brick detail.
Almost the whole village falls inside the Hadley Wood Conservation Area, and Enfield's 2006 Article 4 Direction removes permitted development on street-facing elevations. We always confirm exactly which walls and roof slopes are protected before deciding between a permitted-development route and a full planning application.
Planning in Hadley Wood (EN4): what to know before you apply
Rear and side extensions in Hadley Wood almost always go in as full householder planning applications with a heritage justification, because the conservation area and Article 4 Direction strip back permitted development. Discreet rear lofts can sometimes stay permitted where the roof slope is not visible from the street, but this needs checking case by case.
Typical Hadley Wood housing stock
Spacious red-brick detached and semi-detached houses that grew up around the station after 1885, on generous plots with mature trees. Later detached houses fill gaps between the original Crescent and Camlet Way villas.

Double Storey Extension Drawings for Hadley Wood (EN4) homes: the package and the process
Every double storey extension drawings we prepare for an Hadley Wood property is drawn to London Borough of Enfield’s validation standards and tuned to the EN4 constraints above. Here is what the drawing package covers and how the process runs from first survey to approval.
A double storey extension builds a second floor above a single-storey side or rear addition, typically adding a bedroom and bathroom upstairs over a widened kitchen or reception room below. Because the foundations and roof of a single-storey extension already carry most of the fixed cost of building, adding a floor on top is often the most cost-effective way to gain two rooms rather than two separate projects. The trade-off is scrutiny: a two-storey addition sits closer to eye level with neighbouring windows and gardens, so councils examine massing, roofline and boundary distance more closely than they would a single-storey extension.
DrawingsDirect draws double storey side and rear extensions for full planning and building regulations, with structural calculations for the additional floor load and foundations produced in-house by our MCIAT-chartered team, on a fixed fee. If a single storey is enough, see our Rear Extension and Side Return Extension pages, or combine both with a Wraparound if you are extending sideways as well as up.
Do I need planning permission for a double storey extension in London?
Almost always. Permitted development rights for two-storey extensions are far more restrictive than for single-storey work, particularly on how close the new structure can come to a boundary and how closely its roof pitch and eaves height must match the existing house, so most double storey projects are drawn and submitted as full householder planning applications rather than relying on permitted development.
Where the property sits in a conservation area or is subject to an Article 4 direction, any remaining permitted development allowance for a second storey is typically removed entirely, reinforcing the need for a full application. We check your property's status and your borough's design guidance before drawing.
How do councils control the impact of a double storey extension on neighbours?
Because a second storey introduces new windows and massing at first-floor level, London boroughs apply design guidance aimed specifically at protecting neighbouring light, privacy and outlook.
- The 45-degree rule, tested at neighbouring windows, to check the extension does not block an unreasonable amount of daylight
- A common design expectation that a two-storey side extension is set in roughly 1 metre from the shared boundary, rather than built hard against it
- A first floor commonly set back from the ground floor front elevation, so the upper storey reads as subordinate to the main house from the street
- Obscure or high-level glazing on flank walls facing directly into a neighbour's garden or windows, to limit overlooking
