Balcony Planning Permission in Bournemouth: Do You Need It?
Planning permission for a balcony in Bournemouth is one of the questions we get asked most when people start sketching out a rear extension or a loft conversion. The short answer is that a proper walk-out balcony or roof terrace almost always needs a full planning application, while a Juliet balcony usually doesn't. The detail sits in the gap between those two, and that's where projects either sail through BCP Council or get stuck for months.
We design and build balconies and roof terraces across Bournemouth, Poole and Christchurch, so this is how the rules actually play out on real houses here, from Southbourne semis to the bigger plots in Talbot Woods.
Why balconies fall outside permitted development
Permitted development lets you do a fair bit to a house without applying, including many single-storey extensions and loft dormers. Balconies are the exception. The national rules specifically exclude any verandah, balcony or raised platform from householder permitted development, and a raised platform means anything more than 0.3 metres above ground level. That's roughly the height of two steps.
So if your plan involves standing outside at first-floor level, or on a flat roof over the kitchen, you'll need a householder planning application, which currently costs £548 in England. It doesn't matter how small the balcony is or that it only faces your own garden. Raised decking that creeps over 30cm is caught by the same rule, which catches out a lot of people with sloping gardens in Bournemouth.
Juliet balconies: the usual way round it
A Juliet balcony is a pair of French or bi-fold doors with a glass or metal balustrade fixed across the opening and no platform to step onto. Because nobody can stand outside, there's no real overlooking, and on a house it's normally treated as permitted development. There are a few situations where that changes, though:
If you live in a flat or maisonette, there are no householder permitted development rights, so even a Juliet balcony usually needs permission.
Listed buildings need listed building consent for almost any change, including a new door opening.
In conservation areas, such as parts of the East Cliff and Boscombe, BCP will look more closely at changes to the front or side of a house.
Some newer estates had permitted development rights removed by a condition on the original approval, so it's worth checking your deeds or the planning history.
If you're not sure, a Lawful Development Certificate gives you written confirmation from the council. We'd rather spend a few weeks getting that certainty than build something and have to take it down.
What BCP Council looks for in a balcony application
In our experience the decision nearly always comes down to privacy. Planning officers want to know who you'll be able to see from the balcony and how close they are. A first-floor balcony on a tight terraced street in Winton is a very different conversation to one looking down a long garden in Queen's Park.
These are the things that tend to help an application:
Obscure-glazed privacy screens on the sides facing neighbours, typically 1.7 metres high measured from the balcony floor.
A modest depth, so it reads as somewhere to step out and enjoy the view rather than a second living room.
Materials that match the house or sit comfortably with it, which matters more on period properties.
Clear drawings that show sightlines into neighbouring gardens and windows, so the officer doesn't have to guess.
The council's target for deciding a householder application is 8 weeks from the date it's validated. Most straightforward ones land close to that, though a neighbour objection or a request for amended drawings can stretch it. Plots with sea views along the cliffs and around Southbourne tend to draw more interest from neighbours, so we allow for a bit of back and forth there.
Building regulations are a separate step
Planning permission decides whether you can have a balcony. Building regulations decide how it's built, and you need both. On a typical house these are the main points we deal with:
Structure. A balcony has to carry people, furniture and wind load. Cantilevered designs usually need steelwork tied back into the house, which is where our structural building work comes in.
Guarding. Approved Document K requires balustrades on balconies and roof edges to be at least 1100mm high, with no gaps a child could climb or slip through.
Waterproofing and insulation. If a terrace sits over a heated room, the roof below has to meet thermal and weatherproofing standards, and the rainwater needs somewhere sensible to go.
We don't cut corners on any of this. Building control inspects at key stages and you get a completion certificate at the end, which your solicitor will ask for when you sell.
How we handle a balcony project in Bournemouth
Most of our balcony work around Bournemouth follows the same order. We come out for a survey visit, look at the house and the neighbours' windows, and talk through what you actually want to use the space for. Morning coffee needs a lot less room than a dining table for six. From there we arrange the drawings, prepare the planning application with the privacy details already designed in, and give you a clear written price for the build once we know what the council will accept.
The build is carried out by our own team as part of our balcony and roof terrace work, so the people who planned it are the ones on site. If you're weighing up a terrace on an existing flat roof instead, our guide to roof terraces and balconies in Poole covers what's involved on the build side.
