The donation goes to one or more of the seller's GBs. Since the trades are unbalanced in their favour - Iron Age for Modern Era, for example - the buyer also offers a FP donation to the 'seller' to make up for this difference.

The 'buyer' (the player wishing to construct the GB) offers trades of whatever goods they have for the needed goods. Because there is no formal mechanism to make such transactions, these deals are virtual 'handshake agreements' and require trust on both sides. Players have worked around this by finding other players willing to 'sell' the necessary goods in exchange for forge points. As a result, it's not easy for a player to gather the necessary goods to construct higher age Great Buildings on their own. Typically a player can only gather goods of their age or below, and trade ratios mean trading up one age at a time would be very costly. Why is this done? Construction of a Great Building requires goods from the building's age.

The common situation is being several (or many) ages away from the GB in question, like lower age players wishing to boost their game through having a Chateau or an Alcatraz.

Buying Great Building kits means getting the goods you need (once you have all the BPs) from someone else because you can't produce them on your own.
