Double Storey Extension Drawings in Enfield
Fixed-fee, MCIAT-chartered double storey extension drawings for Enfield homeowners — London Borough of Enfield validation and local constraints handled from the start.
Enfield runs from the dense Victorian and interwar streets of Edmonton and Ponders End up through the Edwardian villas of Winchmore Hill and Bush Hill Park to the green-belt fringe beyond Enfield Town. Loft conversions and rear extensions on the borough's abundant interwar semis across Edmonton, Palmers Green and Southgate are the signature projects, and for those homes hip-to-gable and dormer lofts frequently qualify as permitted development within the volume limits. Conservation control tightens around the historic core and green belt limits scale to the north.
The constraints that shape a scheme depend on where you are. The London Borough of Enfield controls design within conservation areas such as Gentleman's Row, Forty Hall, Bush Hill Park, Winchmore Hill Green, Bulls Cross and Clay Hill, where permitted development is restricted. Green-belt policy toward the northern edge assesses extensions against strict limits on disproportionate additions to the original dwelling, so scale and siting must be evidenced carefully. A borough-wide Article 4 direction removes permitted development for change of use to an HMO, so any conversion to a house in multiple occupation needs a full application anywhere in the borough.
We prepare Enfield planning drawings that respect the established suburban building line the council expects, checking permitted development eligibility for semis and villas first and flagging any conservation, green-belt or Article 4 constraint for your address. You get a fixed fee agreed up front, the same council-accepted drawings an architect would produce for usually around 30% less, a roughly seven-day drawing turnaround and free redraws until Enfield approves. Most householder applications are determined within the statutory eight weeks once validated, so we work to the council's validation checklist to avoid the drawing queries that cause most delays.
Planning in Enfield: what to know before you apply
Enfield operates a borough-wide Article 4 direction removing permitted development rights for HMO conversions, controls design within conservation areas such as Gentleman's Row and Bush Hill Park, and applies green-belt policy toward its northern edge. For the borough's interwar semis, hip-to-gable lofts and rear extensions frequently qualify as permitted development — we confirm before drawing.
Typical Enfield housing stock
Interwar semi-detached suburbia across Edmonton, Palmers Green and Enfield, Victorian and Edwardian villas around Winchmore Hill and Bush Hill Park, and larger houses and green-belt properties toward the borough's northern edge.

Double Storey Extension Drawings for Enfield homes: the package and the process
Every double storey extension drawings we prepare for a Enfield property is drawn to London Borough of Enfield’s validation standards and tuned to the local 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
