PPE double entry -Verge

Question:
Verge was given a building by a private individual in February 2012. The benefactor included a condition that it must be brought into use as a train museum in the interests of the local community or the asset (or a sum equivalent to the fair value of the asset) must be returned.
The fair value of the asset was $1•5 million in February 2012. Verge took possession of the building in May 2012. However, it could not utilize the building in accordance with the condition until February 2013 as the building needed some refurbishment and adaptation and in order to fulfill the condition. Verge spent $1 million on refurbishment and adaptation.

My query:
The cost of the building would be 1 + 1.5=2.5, but since the building was GIVEN where would the credit of 1.5 go to? The answer has p & l but i don’t understand why.
