This is a funny little house. My only real interest in it is that I used to live in it. There’s been some work done on it since, but you can take that BER rating seriously.
The ad doesn’t mention the fact that this is essentially the former security hut at the entrance to a quite large apartment complex. (I lived in a one bed apartment in The Elms around '88/'89. Loved it.)
I think that the price is to do with the potential to build a house on that site that would sell for €1m+ in that location. Or maybe even better two €750k semis side by side if planning is obtained. There have been many new build largish houses built on small sites all around good areas of SCD.
