Change of Use Drawings in Hackney
Fixed-fee, MCIAT-chartered change of use drawings for Hackney homeowners — London Borough of Hackney validation and local constraints handled from the start.
Hackney runs from the Georgian and Victorian terraces of De Beauvoir and Stoke Newington through dense flat-conversion streets to the warehouse quarters of Shoreditch and Hackney Wick, so the right route for an extension or loft depends heavily on both the building type and its conservation designation. A rear extension in Clapton is a very different application from a roof alteration in the De Beauvoir conservation area, and the borough's tight urban plots with shallow rear gardens shape what is realistically achievable on the terraced streets.
Conservation control is unusually far-reaching here: a very high proportion of streets fall within designated areas such as De Beauvoir, Clapton Square, London Fields, Stoke Newington Church Street, Mapledene and Broadway Market, where permitted development for many external works is removed. On top of that, the London Borough of Hackney operates a borough-wide Article 4 direction removing permitted development for change of use to an HMO, and further directions strip rights across many conservation areas. Because so many homes across Hackney Central, Dalston and Hoxton are converted flats, ownership, lease and shared-structure considerations often matter as much as the planning route itself.
We prepare Hackney planning drawings to the council's validation and design standards, screening the conservation-area status and any flat-conversion ownership context for your exact address before recommending a route to consent. You get a fixed fee agreed up front, the same council-accepted drawings an architect would produce for usually around 30% less, a roughly seven-day drawing turnaround and free redraws until Hackney approves. Most householder applications are determined within the statutory eight weeks once validated, so a validation-first submission is the surest way to avoid the drawing queries that cause delay.


Planning in Hackney: what to know before you apply
Hackney operates a borough-wide Article 4 direction removing permitted development rights for HMO conversions, and its numerous conservation areas — De Beauvoir, Clapton Square and London Fields among them — remove permitted development for many external works. Because so many properties are converted flats, ownership and shared-structure considerations often matter as much as the planning route. We confirm both before drawing.
Typical Hackney housing stock
Victorian and Georgian terraces across Stoke Newington, Clapton and De Beauvoir, dense purpose-built and converted flats, and former warehouse and light-industrial buildings converted to housing around Shoreditch, Hoxton and Hackney Wick.

What the numbers say about Hackney planning decisions
These are London Borough of Hackney’s own reported figures, published by government rather than estimated by us. They are what we design against — a borough that refuses one householder application in five needs a different drawing package from one that refuses one in twenty.

Change of Use Drawings for Hackney homes: the package and the process
A change of use application is decided on what the building is, what it becomes, and what that changes. The drawings show the existing use class layout and the proposed one at the same scale, with a floor area schedule for each so the officer can see exactly what is moving between uses.
The supporting drawings usually matter as much as the plans. Access, parking, servicing arrangements, refuse storage and any external alteration all get drawn, because the objections to a change of use are rarely about the internal layout — they are about what the new use does to the street.
The building's form limits what it can honestly become. A ground-floor unit with its own frontage converts to residential more readily than upper floors reached through a shared entrance, and a deep plan with windows on one elevation only will struggle to give a habitable room adequate light whatever the policy position.
What counts as a material change of use?
Not every change in how a building is used needs planning permission — only a 'material' change, one significant enough to affect the character of the use of the land. Converting a single dwellinghouse into two or more flats is always material. Adding paying lodgers within a single household usually is not, until the household tips over into a small House in Multiple Occupation. We assess whether your proposed change crosses that threshold before recommending a route.
The Use Classes Order: C3, C4, E and sui generis
The Use Classes Order groups uses so planners, and permitted development rules, can treat similar activities consistently.
C3 — Dwellinghouses
The class covering a single household living as a single unit, including up to two people living together as a single household who are not related. Most family homes and self-contained flats fall here.
C4 — Houses in multiple occupation (small)
Covers a shared house or flat occupied by three to six unrelated people sharing basic amenities such as a kitchen or bathroom. Moving from C3 to C4 is a change of use, though it is often permitted development unless your borough has removed that right.
Class E — Commercial, business and service
A wide class combining shops, offices, gyms, cafes and other business uses that can change between each other without planning permission, but changing from Class E to residential use is a material change requiring the prior-approval or full planning route.
Sui generis
Uses that do not fit any class, including large HMOs of seven or more unrelated occupants, betting shops and drinking establishments. A change of use to or from a sui generis use normally needs planning permission.
Do I need full planning permission or can I use prior approval?
Some changes of use are permitted development subject to a prior-approval application rather than full planning permission — the best-known example is Class MA, which allows certain Class E commercial premises to become residential (C3) subject to the council assessing specific matters such as flooding, contamination and noise, without a full application. Other changes, including most conversions of a house into self-contained flats, fall outside any prior-approval route and need full householder or full planning permission. We identify which route applies to your building before drawing anything.
| Route | When it applies | Typical package | Fee from |
|---|---|---|---|
| Prior approval (Class MA) | Class E commercial to residential, meeting the criteria | Prior-approval drawings and statement | £1,200 |
| Full planning permission | Conversion into flats, HMO or use outside prior approval | Planning + building regs | £1,600–£2,400 |
| No application needed | Use falls within an existing permitted class change | Drawings for record purposes only | £450 |
