Double Storey Extension Drawings in Hoxton N1
Fixed-fee, MCIAT-chartered double storey extension drawings for Hoxton (N1) homeowners — London Borough of Hackney validation and local constraints handled from the start.
Hoxton is a layered N1 neighbourhood of Georgian and Victorian terraces around Hoxton Square and Regent's Canal interspersed with post-war estate blocks. The typical work spans side-return and rear kitchen extensions and loft conversions on the period terraces, and internal reconfiguration or conversion of flats within the denser and estate stock.
Where homes sit within the Regent's Canal, Hoxton Street or De Beauvoir conservation areas, roof alterations and canal-facing elevations are assessed closely for townscape impact. We prepare Hoxton drawings to the London Borough of Hackney's conservation and amenity standards, resolving party-wall lines, daylight angles and heritage detailing before submission so the application clears cleanly.
Planning in Hoxton (N1): what to know before you apply
No published householder Article 4 direction applies across Hoxton, so many terraced rear and loft projects proceed under permitted development; homes within the Regent's Canal, Hoxton Street or De Beauvoir conservation areas have reduced PD rights and need a householder application with careful roof and elevation detailing.
Typical Hoxton housing stock
Hoxton mixes Georgian and Victorian terraces around Hoxton Square and the canal with substantial post-war estate blocks. The period terraces along Wilton Square and Noel Road support side-return and rear extensions and loft conversions, while much of the flatted stock calls for internal reconfiguration and conversion drawings rather than garden additions.

Double Storey Extension Drawings for Hoxton (N1) homes: the package and the process
Every double storey extension drawings we prepare for an Hoxton property is drawn to London Borough of Hackney’s validation standards and tuned to the N1 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
