The B side of the "Wish for children" card titled "Urgent wish for children" requires you to build a "Dwelling" prior to family growth. Dwelling is written with a capital D on the card. Does that mean that you are required to build the regular dwelling priced at 4 wood, 3 stone that gives you 3 goal points or are you allowed to build any of the different types of dwellings?
I don't think the capital D in "Dwelling" has any significance. In the rule book Dwelling is always capitalized. I would think that you could build any of the Dwellings. If you couldn't, I think there would be a specific explanation in the rule book.
