Double Storey Extension Drawings in Addiscombe CR0
Fixed-fee, MCIAT-chartered double storey extension drawings for Addiscombe (CR0) homeowners — Croydon Council validation and local constraints handled from the start.
Addiscombe in CR0 sits just east of central Croydon and blends Victorian and Edwardian terraces with interwar semis on generous suburban plots. It is very much a family-extension neighbourhood, so most of our work is rear and side extensions, loft conversions and garage conversions that add practical space for growing households.
Away from the East India Estate conservation area, much of Addiscombe is comparatively permitted-development friendly, which can open up straightforward routes to more space. Where conservation control or a larger scheme applies, we prepare full planning drawings that address Croydon's amenity, scale and materials tests so the application is assessed on solid ground.
Planning in Addiscombe (CR0): what to know before you apply
There is no published householder Article 4 direction we depend on for Addiscombe, and much of the suburb benefits from permitted-development rights for modest extensions and lofts. The main exception is the East India Estate conservation area, where frontage, roof and material changes are more tightly controlled; elsewhere neighbour amenity and extension depth are the key limits.
Typical Addiscombe housing stock
Addiscombe, east of central Croydon, mixes Victorian and Edwardian bay-fronted terraces with interwar semi-detached housing along its residential streets. It is a strong family-extension market, so the common projects are rear and side extensions, loft conversions and garage-to-room conversions that add space without the tight constraints of inner London.

Double Storey Extension Drawings for Addiscombe (CR0) homes: the package and the process
Every double storey extension drawings we prepare for an Addiscombe property is drawn to Croydon Council’s validation standards and tuned to the CR0 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
