London Borough of Enfield standards at a glance

4 numeric standards taken from London Borough of Enfield's own adopted documents, each shown with the paragraph it comes from. Figures differ between councils — these are this one's.

Rear extension depth

up to 3m

Enfield allow 3 metres on a terrace or semi, with a 3 metre eaves height. These are Local Plan policy figures rather than guidance, so there is less room to argue around them than in a borough where the numbers sit in an SPD. Enfield DMD 11 para 2a

up to 4m

Enfield allow 4 metres on a detached house, with the same 3 metre eaves height. Enfield DMD 11 para 2a

Side extension form

at least 1m

Enfield require a metre kept clear to the side boundary, and reserve the right to ask for more where the street is more spacious. Enfield DMD 14 para 1

Amenity neighbouring

at least 22m

Enfield want 22 metres between rear windows for houses up to two storeys, rising to 25 or 30 metres once three storeys are involved, and 11 metres from a window to a side boundary. Enfield DMD 10, Table 2.2

Standards are what the council normally expects, not a guarantee. A scheme outside them can still be approved on its merits, and one inside them can still be refused for another reason.

Authored Policy Library

9 local policy checks, each citation-locked to the adopted document. National policy (NPPF, national space and daylight standards) applies alongside these.

Enfield Development Management Document (2014)

• Enfield DMD Policy DMD 37 — Design character (provisional citation) Enfield will judge how well your proposal responds to your house and street under their design policy DMD 37. Keeping additions subordinate and materials matched is the safest starting point.
• Enfield Development Management Document (residential amenity policies) — Amenity neighbouring (provisional citation) Enfield will look at the effect on your neighbours' light, outlook and privacy. Show the relationship to their windows on your drawings.
• Enfield DMD 11 para 2a — Rear extension depth (2 checks) Enfield allow 3 metres on a terrace or semi, with a 3 metre eaves height. These are Local Plan policy figures rather than guidance, so there is less room to argue around them than in a borough where the numbers sit in an SPD. Enfield allow 4 metres on a detached house, with the same 3 metre eaves height.
• Enfield DMD 11 para 2a — Amenity neighbouring Enfield draw a 45-degree line from the middle of your neighbour's nearest ground floor window. This matters more than the 3 metre figure on its own: schemes deeper than 3m have been approved where this line is respected, and refused where it is not. Give the projection and the sideways distance to that window and the line is drawn for you.
• Enfield DMD 11 para 3a — Amenity neighbouring Enfield use a 30-degree line for first floor rear extensions, not the usual 45. Measured from the rear wall that is much tighter - roughly 0.6m of projection for every metre sideways, against 1m for a 45-degree borough - so an upper floor extension that would be fine next door may not be accepted here.
• Enfield DMD 14 para 1 — Side extension form Enfield require a metre kept clear to the side boundary, and reserve the right to ask for more where the street is more spacious.
• Enfield DMD 10, Table 2.2 — Amenity neighbouring Enfield want 22 metres between rear windows for houses up to two storeys, rising to 25 or 30 metres once three storeys are involved, and 11 metres from a window to a side boundary.
• Enfield DMD 13 para 1a — Roof form Enfield want a dormer set in between 500mm and 750mm from the eaves, ridge and each side of the roof.
