planning permission

do you need planning permission to have a roof garden on top of a garage roof?
thanks!

Better to speak to a local building surveyor or planning expert
maybe give the council planning office a call without giving details.
Will need to check if the roof can take the weight and may well need building regs

I don't know if the rules have changed over the past few years, but know once when my ex and I were thinking of doing this, planning permission was refused.

As dimbo suggests, a quick phone call to your planning dept will answer your question.

oh wow, really? will it depend on the area I guess?
I'll give them a call, thanks

You need to consider the structural implications. A roof is designed only to support ts own weight and the occasional maintenance man. You will need to upgrade it so that it is effectively a floor.

Yes, we know that the roof has been reinforced already

I think you probably would need planning permission as you'll be changing the use of the roof of the garage to additional amenity/garden space along any consequential additions to the roof such as parapets would constitute development requiring planning permission. The use of roof could have implications for overlooking next door's garden etc. if you dont have any near neighbours you should be ok. if your garage is right next to someone's garden they will probably object and the council will have to take a view as to whether or not this would be acceptable.

On the plus side, you can argue that you are helping to reduce the surface run off rate and contributing to flood preventation in a sustainable way.

The planners should be supportive of this, as it helps offset the amount fo people converting their gardens to driveways.

Basically, when it rains heavily, the water runs off tarmac or a roof very quickly, meaning that the sewers fill up immediately and are more likely to get flooded.

Rain that falls on grass takes much longer to make its way through into the drainage system, so you're basically helping to prevent floods by changing roof to greenery.

Planners are starting to use flood prevention as an excuse to reject applications to turn gardens into driveways (because more rainwater would be entering the drains during a storm), so I reckon you could use the reverse argument in support of your plan to turn your roof into a garden.

many thanks for the clarification!:T

I didn't know a permission was needed to turn a garden into a driveway!
