Double Storey Extension Drawings in Bexley Village DA5
Fixed-fee, MCIAT-chartered double storey extension drawings for Bexley Village (DA5) homeowners — London Borough of Bexley validation and local constraints handled from the start.
Bexley Village (DA5) sits on the River Cray at the south-eastern edge of the borough, where the historic High Street winds down past cottages and shops to the green and St John's Church. Rear and side extensions on the Victorian and Edwardian houses ringing the old core are the most common projects here, and the village's semi-rural setting on the edge of the Metropolitan Green Belt shapes how the council reads them.
The Old Bexley Conservation Area, first designated in 1971 and extended in 1987, covers the winding High Street, the green and the riverside around the old ford, protecting 18 listed buildings and the prevailing local brick. Where a DA5 property sits relative to that boundary decides whether roofline, window and front-elevation changes are permitted development or need consent.
Planning in Bexley Village (DA5): what to know before you apply
Inside the Old Bexley Conservation Area the Article 4(2) Direction means front-elevation, roof, window and boundary changes that would be permitted development elsewhere need a full householder application, and the 18 listed buildings additionally require listed-building consent. Beyond the boundary, on the Edwardian and inter-war streets toward the station, many rear and loft projects still fall within permitted development, so we check the boundary and the Green Belt edge before advising a route.
Typical Bexley Village housing stock
The conservation-area core is a tight grain of 18th- and 19th-century brick cottages, listed timber-framed houses and Victorian shopfronts along the winding High Street, giving way to Edwardian villas and inter-war semis on the rising ground toward Bexley station and Parkhill Road.

Double Storey Extension Drawings for Bexley Village (DA5) homes: the package and the process
Every double storey extension drawings we prepare for an Bexley Village property is drawn to London Borough of Bexley’s validation standards and tuned to the DA5 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
