I am relatively new to Horizons, so please bear with a few newbie questions regarding building.

1. On Horizons.gamersinfo.net I noticed a list of buildings. Among them were various racial buildings (e.g. Saris tiny hut, human medium store, fiendish large house). I don't see anything specifically for 1/2 giants. Do they exist?

2. Are certain structures limited to certain areas around racial cities? Again, I am wondering if as a 1/2 giant it makes sense to buy a plot near Mahagra? Are there any advantages to doing/disadvantages to not doing so?

Thanks in advance.
