I think u misread my post. Our estate has not been taken in charge therefore no taxes paid by anyone goes towards the lighting and maintenance of it.
It will be in a few months though
I was making the point that the only way to restrict usage would be to take charge of it yourselves and pay a management company to maintain it.
There are plenty of 'estates' in Dublin like this.
The only case you could make to the council would be that the learners were posing a danger. I don't think you could argue that they're spoiling the look of the place.
