That translates into ~5000 estates nationally. In certain cases completion bonds are in place that would finish the work. Contact the planning section and tell them to get the finger out. However councils do not take over complete estates until they are at least 5-7 years old. I would guesstimate that at least 50 of the 150 are fine.
In certain cases the developers of these estates are bankrupt. They can’t afford to pay the banks back what they owe them and so the banks won’t release the completion bonds.
A built but unfinished apartment block on FortunesTown Lane had been boarded up and locked for months. Builders on it today taking down hoardings and looking like they are going to finish it.
There is an affordable housing estate up in Ladyswell D15 that Fingal Co. Co. couldn’t sell. That may still be vacant.
I saw some short film on RTE2 a few weeks ago where a bloke was the only person left and he was walking around an empty dublin estate.
