Prior approval drawings in Hackney

Why most Hackney addresses are ruled out before drawing starts

Only 18.8% of Hackney households live in a house or bungalow, and just 24.6% are owner-occupiers. Flats and maisonettes have no larger home extension right, so the first question for most enquirers is simply whether their home is a dwellinghouse in the legal sense.

For those who do own a whole house, the numbers explain the interest: a terraced house in the borough averaged £960,633 on the latest Land Registry figures and a semi £1,193,876. At those values extra floor area is worth a great deal, which is why owners pursue a notification despite the limits.

Article 4 directions and conservation areas

The council has published 77 Article 4 directions covering 197 separate areas, and 37 conservation areas. Land inside a conservation area is excluded from the larger home extension route, and an Article 4 direction can withdraw the underlying permitted development right for a specific class of work.

Read together, those figures mean a street-by-street check is unavoidable. Two houses on opposite sides of a road can be in different positions. We overlay the council's published boundaries on your plot and report the result in the free constraints check. Where the right has been withdrawn, a householder application is needed, and our planning drawings service covers that route in full.

What we draw for the notification

The Order requires: Written description (depth beyond rear wall, max height, eaves height), site plan, addresses of adjoining premises, developer contact address. We prepare that set and add scaled plans, a rear elevation and a section through the neighbouring windows. The site plan follows the conventions of our location and block plans, because it is the sheet an officer reads first.

In a Victorian terrace the rear elevation may include closet wings and outriggers that make the original rear wall hard to identify. Our survey records the wall as first built, because the allowance is measured from it, and flags where a later addition has changed what counts as the starting line.

The council fee is £249, paid to the council. We fix our own fee after the free check, and a second technologist reads the submission before it is sent.

Hackney's householder decisions as a benchmark

The borough decided 415 householder applications in its latest year and granted 84.6% of them, with 91.3% decided within the statutory period or an agreed extension. Those are the conditions into which any refused notification would fall back.

We mention this because the choice between prior approval and a householder application is genuinely open in Hackney. A notification is faster, but an application lets the officer weigh design merits as well as impact, which can help when a neighbour's objection is about appearance and not light. We set out both for you before you commit.

How we decide whether to recommend the route

Three tests decide it. First, whether the building is a house in law, with no flat conversion in its history. Second, whether the plot sits outside every conservation area and Article 4 direction that would shut the route. Third, whether the extension you want fits inside the Order's limits while still going beyond ordinary permitted development.

If any test fails, the recommendation changes, and the quote follows the route and never the other way round. A Hackney house that passes all three goes ahead to survey, where we record the rear wall as first built, the neighbours' windows and the boundary, then draw the notification for a second technologist to check.

Certificates, neighbours and where to go next

If your extension stays inside ordinary limits, a Lawful Development Certificate is the cleaner proof; Hackney decided 258 of them in the same year. Prior approval is for the extension that needs to go further.
