structural changes to apts

#1
Hi all
Originally from the Donaghmede area .and have rented in GrattanWood in the past.
I am interested in buying an Apartment in the complex that is currently for sale
However internally its been changed from a 2 bed Apt to a 3 bed apt and I am wondering has this been done with the management company's permission and has the structural work been approved for fire safety etc.
The estate agent is being vague on the issue and I'm not at all sure hes interested in finding out,
I cant get an answer from the management company as the phone either rings out or I am put on hold
Any advice appreciated
