many thanks for the clarification!:T



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

if the area you are paving is greater than 5 square metres (i believe) you need planning permission.

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.

i didnt get the impression that the OP was looking to construct a green roof, more that he wanted to use his garage roof as amenity space. but you are of course right that it was a green roof it would help with flooding/drainage etc. but the down side if they are a lot more expensive than tiles/impermeable coverings.

True. The OP just described it as a roof garden, so it could be either.

I wonder whether there's a market for some kind of packaged garage roof garden?! Given the amount of unused roof space throughout the country, there must be something that could be marketed.... even if it was only a visual improvement that didn't require structural reinforcement.... hmm, next stop Dragon's Den!

its my understanding that due to the weight of green roofs it adds additional cost to the build, which is why they are so unpopular with the development industry. a light weight version that didnt need structural reinforcements could be a goer.

Although strange, a garden on top of a garage in the garden of a dwelling hasn't involved any change of use to the curtilage of the dwelling has it? Still all single dwelling.

If there are any building or engineering works involved in creating the garden then they would require permission and then the Council might well refuse.

Because of the increasing number of roof terraces/gardens it is increasingly the case that permissions for single storey extensions have specific conditions preventing their roofs being used in that way. If such conditions have not been imposed there is usually nothing to stop the use as a garden - it is the railings or whatever that cause the problem.

When people want to build a terrace on top of a flat roof extension, or a flat roof garage attached to the house, our local authority view it as a flat roofed first floor extension (with an invisible roof) - in that the same criteria are use for deciding if it will need PP, or pass (e.g. overlooking).

I don't know if this is a national thing. Different local authorities have their own ideas.

If you have a flat roofed house then why can't you sit on the roof?

As I have said it is only when you do something more - i.e. do some building that they have any control. Mere use of a roof, although possibly a safety hazard etc without railings etc, cannot require permission.

If you analyse it you have to ask whether there has been a material change of use to the planning unit as a whole - still a dwelling - or whether any building engineering or other operation has taken place. If no operation has occurred or is intended then I can't see why planning permission would be required.

you're right -I should have said roof terrace - maybe add railings and a few plants and chairs

so basically,are you saying that I would not need permission?
and if I wanted to add railings?
