Double Storey Extension Drawings in Barkingside IG6
Fixed-fee, MCIAT-chartered double storey extension drawings for Barkingside (IG6) homeowners — London Borough of Redbridge validation and local constraints handled from the start.
Barkingside (IG6) is a largely inter-war suburb, so most of the district's rear extensions, lofts and side infills sit on ordinary 1920s and 1930s semi-detached and terraced stock outside any heritage designation. That gives many IG6 houses reasonable permitted-development scope for household projects.
At its heart, though, is the Barnardo's Village conservation area on Tanners Lane — the surviving part of Dr Barnardo's Girls' Village Home, a horseshoe of Grade II-listed cottage homes built between 1876 and 1895 around a village green. Anything affecting those listed cottages or their setting needs listed-building consent as well as planning permission, a far tighter process than the surrounding streets.


Planning in Barkingside (IG6): what to know before you apply
Redbridge keeps its Article 4 directions off planning.data.gov.uk, so we verify each IG6 address against the council's conservation-area and listed-building layers directly. The Barnardo's Village conservation area carries both conservation-area control and Grade II listings, so projects there are exceptional; across the wider inter-war suburb, standard rear and loft work is generally well supported.
Typical Barkingside housing stock
Mainly 1920s-1930s suburban semis and terraces typical of outer Redbridge, wrapped around the Barnardo's Village conservation area on Tanners Lane — a horseshoe of Grade II-listed cottage homes built for Dr Barnardo between 1876 and 1895 around a village green, with the Children's Church and Cairns House.

Double Storey Extension Drawings for Barkingside (IG6) homes: the package and the process
Every double storey extension drawings we prepare for an Barkingside property is drawn to London Borough of Redbridge’s validation standards and tuned to the IG6 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
