Go into Land Registry Setanta Centre Nassau Street. You can a mapping search. If the lands are registered then the map will connect to a folio number which will indicate owner. If lands are not registered, it may be more problematical. Who is making the application? Could it be the original developer or someone he has sold to? You could also check your own deeds - specifically the planning permissions - is there anything in that about the green space? Finally, should you object to the application? And if so, on what grounds?
