Dear Carol,

I am not really clear about the content of the power of attorney and the principal agreement between you and the builder. Firstly, we should focus on the agreement in regard to building a house (or whatever it is). What clauses does it have in connection with the "final condition" of the property? You might have signed such a contract that did actually not offer you a property with all those installations (only, as a consideration). I believe, but not sure, that the contract binds the builder with those installations and etc. So does, you may have two options; send a notice to your agent just to have the builder finished the rest of the work. Do not forget that your agent is responsible against you with the obligation of "due diligence." They can not avoid to deal with you.
The second option is that you pay for the installations and other works to be done, and then commence a lawsuit against both your agent and the builder.
I would give you more detailed and further information if you discuss it more.
All the best.
