Double Storey Extension Drawings in Leyton E10
Fixed-fee, MCIAT-chartered double storey extension drawings for Leyton (E10) homeowners — London Borough of Waltham Forest validation and local constraints handled from the start.
Leyton (E10) in Waltham Forest is a dense grid of bay-fronted late-Victorian terraces built as the railways arrived, on the streets around Francis Road and Colchester Road. Rear and loft projects on these terraces are the staple, worked around a High Road conservation area and a strong, consistent terrace character.
Two conservation areas bracket the district: Leyton Town Centre along the High Road, with its listed former Town Hall and library, and Bakers Arms around the Master Bakers' Almshouses on the Walthamstow border. Waltham Forest also runs an Article 4 direction on house-to-HMO conversions, so we check the conservation-area boundary and the intended use before advising on a permitted-development or full-application route.
Planning in Leyton (E10): what to know before you apply
Leyton terraces generally keep permitted development rights for rear and loft work, but the Leyton Town Centre and Bakers Arms conservation areas control the High Road and the almshouses setting, and Waltham Forest's Article 4 direction removes the right to convert a house to a small HMO without permission. The tight, uniform terrace plots mean extension depth and dormer proportions are judged closely against the established pattern.
Typical Leyton housing stock
Bay-fronted late-Victorian terraces built roughly 1870–1910 as the railways arrived, on the streets around Francis Road and Colchester Road, with the listed former Town Hall and library on the High Road and the Italianate Master Bakers' Almshouses at Bakers Arms.

Double Storey Extension Drawings for Leyton (E10) homes: the package and the process
Every double storey extension drawings we prepare for an Leyton property is drawn to London Borough of Waltham Forest’s validation standards and tuned to the E10 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
