what is the lowest level you can build residential in dun laoghaire ?

Sea point

Hi,

I'm looking at building a new house in a sunken site in Dun Laoghaire. The existing level of the site is very low versus high tide. There are no flooding issues since Dub Laoghaire has granite sea defence walls. However there could be still implications for new residential building.

I've heard that there may be restrictions on how low you can build habitable space in a residential building in Dun Laoghaire.

Does anyone have any experience of this in Dun Laoghaire?

I have heard from a developer in the docklands that Dublin City requires new builds to be over 4 metres above the Malin datum point.

All help appreciated !

I have seen it permitted - not built - on the basis of the provision of expensive attenuation tanks and pumps from same into public drains.
Very celtic tiger , very hassly to obtain consent from drainage dept and very not built.

Well, in Clontarf on the site of the old Dollymount House there is a newly built apartment block on the seafront where the basement car park looks to be well below the high tide level, I remember the huge hole they dug. So there must be ways of getting approval.

DLR do not allow the pumping of surface water afaik.

Why run the risk...easier and cheaper to fight for extra height than all the civils involved in your proposal

The risk too is to the existing developments who would no longer enjoy the benfit of water run off that sunken site affords.
"My house only flooded after yours was built". Suddenly a whole neighbourhood is not insurable. Not a happy place to live then I expect.
