Double Storey Extension Drawings in Wanstead E11
Fixed-fee, MCIAT-chartered double storey extension drawings for Wanstead (E11) homeowners — London Borough of Redbridge validation and local constraints handled from the start.
Wanstead (E11) in Redbridge is a leafy village-centred neighbourhood where late-Victorian and Edwardian houses sit over an older designed landscape of greens, avenues and parkland. Rear and loft projects on the substantial semi-detached and detached stock are the mainstay, closely shaped by three conservation areas that cover much of the district.
The Wanstead Village conservation area runs along the High Street, The Green and St Mary's Avenue toward the Grade I parish church and Wanstead Park, with Wanstead Grove and the Wanstead Park landscape adding further controls. Redbridge does not publish its Article 4 directions to the national register, so rather than claim a permitted-development status we can't confirm from open data, we check the schedule and the conservation-area boundaries with the council first.
Planning in Wanstead (E11): what to know before you apply
Wanstead's defining controls are the Wanstead Village, Wanstead Grove and Wanstead Park conservation areas, which govern frontages, rooflines and the historic landscape setting across E11. Because Redbridge publishes no Article 4 directions to the open register, we confirm a property's permitted-development position directly with the council rather than inferring it, then design to Redbridge's residential and conservation-area guidance.
Typical Wanstead housing stock
Late-Victorian and Edwardian speculative housing overlaid on an 18th-century designed landscape, with substantial semi-detached and detached houses around Grove Park and the High Street, and the greens and tree-lined avenue of the village centre leading toward St Mary's and Wanstead Park.

Double Storey Extension Drawings for Wanstead (E11) homes: the package and the process
Every double storey extension drawings we prepare for an Wanstead property is drawn to London Borough of Redbridge’s validation standards and tuned to the E11 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
