Double Storey Extension Drawings in Woodford Green IG8
Fixed-fee, MCIAT-chartered double storey extension drawings for Woodford Green (IG8) homeowners — London Borough of Redbridge validation and local constraints handled from the start.
Woodford Green (IG8) is Redbridge's leafiest neighbourhood, strung along the High Road (A104) beside the Green — open common land that is part of Epping Forest — with the large Edwardian houses and 1920s semis of the Monkhams estate a short walk from Woodford station. Sympathetic rear extensions and loft conversions on these substantial homes are the mainstay of local work.
Much of the district lies within the Woodford Green and Woodford Wells conservation area, designated in 1970 and amended in 2013, which splits into distinct Woodford and Monkhams character areas and adjoins the Woodford Broadway conservation area. Roofline changes, dormers and front-elevation work face tighter control here, and the Epping Forest boundary adds a further layer to check before any application.
Planning in Woodford Green (IG8): what to know before you apply
With Redbridge's Article 4 directions kept off the national dataset, we confirm each IG8 address against the council's conservation-area and forest-boundary layers directly. Large parts of Woodford Green fall inside the Woodford Green, Woodford Wells or Woodford Broadway conservation areas, so most projects here are assessed for materials, roof form and setting, and the Epping Forest edge can further constrain what is achievable.
Typical Woodford Green housing stock
Large detached Edwardian houses and substantial 1920s semis on the Monkhams estate, alongside a scatter of fine early-eighteenth to early-twentieth-century houses set around the greens, mature trees and ponds where the old hamlets grew up along the road on the edge of Epping Forest.

Double Storey Extension Drawings for Woodford Green (IG8) homes: the package and the process
At first-floor level the drawings have to answer for daylight, privacy and massing. That means proposed elevations showing every new window with its position relative to the boundary, a section taken through the extension and the neighbouring building, and a roof form drawn to sit below the existing ridge rather than compete with it.
We draw the neighbouring property alongside your own, because the officer's assessment is comparative — the effect on their windows and outlook is the test. Setting the first floor in from the boundary, and showing that set-back as a dimension, resolves most objections before consultation begins.
At first floor the boundary relationship decides everything. A detached house has room to set the addition in on both sides; a semi has one shared wall and one clear flank; a mid-terrace can usually only go to the rear, where the effect on both neighbours has to be drawn.
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
Matching the roofline and materials
Planning officers assess a double storey extension heavily on how convincingly it reads as part of the original house rather than an addition bolted onto the side. Our drawings match ridge height, roof pitch, eaves detail and brick or render finish to the existing building wherever the design brief allows, which is consistently one of the strongest factors in securing approval without delay or redesign. Where a subtly contrasting material is proposed instead — a different brick tone, or a zinc or slate roof against a tiled original — we set it out clearly on the elevations so the design intent reads as deliberate rather than a mismatch, which is how most London boroughs prefer a genuine design statement to be presented.
