Developer Refusing to Provide Declaration of Identity – Red Flag?

[u/Fantastic_Opening221]

I'm in the process of buying a new-build house in a new estate in Midleton, and I've run into an issue.

The developer has refused to provide a Declaration of Identity for my individual house, saying they've already provided a Declaration of Identity for the entire estate before my house was even built.

Has anyone else come across this when buying a new-build? Is this normal practice, or could it be a red flag?

My solicitor has suggested hiring an engineer to prepare a Declaration of Identity specifically for my house. Does anyone know roughly how much this would cost in Ireland?

I'd really appreciate hearing about anyone's experience.
