I don't think that - short of an underground bunker - there are fire-resistant structures that can survive a "serious" wildfire. The classification of fire-resistant is usually 30/60/90/120 minutes, meaning that the structure should not collapse before that time, but norms say nothing of the residual structure integrity, and the cost of inspecting, assessing and repairing a structure affected by a fire can in many cases exceed the cost of re-building it from the ground up. Set aside wood/timber, the other three common construction methods, steel, reinforced concrete and brick/stone masonry are all affected by the heat of a (large) fire (in the case of masonry it is the mortar that loses some of its properties), i.e. the structure won't have the same strength as before.
