Double Storey Extension Drawings in Shoreditch EC2A
Fixed-fee, MCIAT-chartered double storey extension drawings for Shoreditch (EC2A) homeowners — London Borough of Hackney validation and local constraints handled from the start.
Shoreditch around EC2A is defined by its former industrial fabric, brick warehouses, workshops and print buildings now reworked as creative lofts, studios and apartments, with the Arts-and-Crafts Boundary Estate nearby. Projects here lean toward change of use, warehouse-to-residential conversion, roof-level and mansard additions and the reconfiguration of loft apartments rather than the suburban rear extension.
The South Shoreditch and Redchurch Street conservation areas protect this warehouse character closely, so visible roof additions and facade alterations are heavily scrutinised. We prepare Shoreditch drawings to the London Borough of Hackney's conservation and change-of-use standards, coordinating planning, fire and building-regulation detail so conversions and roof schemes stand up first time.
Planning in Shoreditch (EC2A): what to know before you apply
No published householder Article 4 direction governs the EC2A part of Shoreditch, but the South Shoreditch conservation area and change-of-use policy mean nearly all warehouse-conversion, mansard and facade work requires full planning permission with detailed heritage and amenity justification.
Typical Shoreditch housing stock
Shoreditch around EC2A is former industrial and warehouse territory, brick workshops, print buildings and factories now converted into creative lofts, studios and flats, alongside the Arts-and-Crafts Boundary Estate. The work here is less about garden extensions and more about change of use, warehouse-to-residential conversion, roof-level additions and internal loft-apartment reconfiguration.

What the wider borough is built of
EC2A has too few classified residential buildings to publish a district figure of its own, so we do not estimate one. The measured figures below are borough-wide and EC2A is not among the districts they cover.
Borough-wide building mix
Residential building form across 5 of the borough's 6 postcode districts, from 2,243 classified buildings. EC2A is below the publication floor and is excluded from these totals, so they describe the borough around it rather than the district itself.

Double Storey Extension Drawings for Shoreditch (EC2A) homes: the package and the process
At first-floor level the drawings have to answer for daylight, privacy and massing. That means proposed elevations showing every new window with its position relative to the boundary, a section taken through the extension and the neighbouring building, and a roof form drawn to sit below the existing ridge rather than compete with it.
We draw the neighbouring property alongside your own, because the officer's assessment is comparative — the effect on their windows and outlook is the test. Setting the first floor in from the boundary, and showing that set-back as a dimension, resolves most objections before consultation begins.
At first floor the boundary relationship decides everything. A detached house has room to set the addition in on both sides; a semi has one shared wall and one clear flank; a mid-terrace can usually only go to the rear, where the effect on both neighbours has to be drawn.
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
Matching the roofline and materials
Planning officers assess a double storey extension heavily on how convincingly it reads as part of the original house rather than an addition bolted onto the side. Our drawings match ridge height, roof pitch, eaves detail and brick or render finish to the existing building wherever the design brief allows, which is consistently one of the strongest factors in securing approval without delay or redesign. Where a subtly contrasting material is proposed instead — a different brick tone, or a zinc or slate roof against a tiled original — we set it out clearly on the elevations so the design intent reads as deliberate rather than a mismatch, which is how most London boroughs prefer a genuine design statement to be presented.
