Double Storey Extension Drawings in Emerson Park RM11
Fixed-fee, MCIAT-chartered double storey extension drawings for Emerson Park (RM11) homeowners — London Borough of Havering validation and local constraints handled from the start.
Emerson Park in RM11 is Havering's most affluent suburb, characterised by large detached interwar houses on wide, tree-lined plots. Work here skews toward ambitious schemes: two-storey and wrap-around extensions, outbuildings, annexes and occasionally full replacement dwellings where the plot supports it.
The spacious, green character means London Borough of Havering scrutinises massing, spacing between houses and tree protection closely, and the Langtons and St Andrew's conservation areas nearby reinforce that heritage backdrop, so we design larger schemes to sit convincingly within the established grain.
Planning in Emerson Park (RM11): what to know before you apply
No published householder Article 4 direction applies in Emerson Park; the practical constraints are protected trees, generous building lines and the low-density character, with the Langtons and St Andrew's Hornchurch conservation areas nearby. Larger plots often support extensions beyond permitted development via full applications.
Typical Emerson Park housing stock
Emerson Park is a leafy, affluent interwar suburb of large detached houses on wide, deep plots between Hornchurch and Upminster. Generous frontages and spacious gardens make it a hotspot for substantial two-storey and wrap-around extensions, garages, outbuildings and full replacement dwellings.

Double Storey Extension Drawings for Emerson Park (RM11) homes: the package and the process
Every double storey extension drawings we prepare for an Emerson Park property is drawn to London Borough of Havering’s validation standards and tuned to the RM11 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
