What is the importance of Brianstown in the novel, Broken Harbor?

After the tourist economy of Broken Harbor dried up during the Celtic Tiger, when families were able to afford holidays in sunnier locales, it was renamed Brianstown. The main housing estate is tritely named Ocean View, and while it seemed poised to become a vibrant community before the recession, afterwards it turned into the quintessential example of a ghost estate, a housing complex nearly abandoned for lack of funds and falling to ruin from neglect. To the Spains, Ocean View represents the destruction of their hopes and dreams. As the shoddy nature of their home is revealed, they realize that what successful Irish society has promised them will not come to pass. The walls begin to crumble down around them, both metaphorically and literally.
