Katoikia

The Katoikia ("Estate"; "manor") is a catch-all term for the line of recruitment buildings which are Alexander's equivalent of the Noble Residence ("villa") from Kings & Conquerors and Swords of the Prophets, and is built by a handful of nations - namely those which are Greek - with one exception.
*Greek nations: Athens, Sparta, Corinth, Thebes, Macedon, Larissa, Epeiros
*Barbaroi: Odrysioi, Paionai, Poeni, Aigyptoi, Tyrrhenoi 
Generally speaking,
*The Katoikia is available only if Red Government 1 (Oligarchy) was researched, along with Classical Age.
*A variant of the Katoikia, the Syssiton, is built mainly by three nations: Sparta, Epeiros and Korinthos. This version however can be built from the beginning of the game, tying these factions less to governments.
*Factions that do not build Katoikion build the Warrior Hall instead.
*The Tokharoi do not build Noble Residences or Warrior Halls, but instead have access to two buildings: the Őrzők Céhe, and the Vár.
Units that are trained from the Katoikia and the Syssiton include:
*Korinthoi: Epilektoi hoplitai
*Larissa, Macedon, Epireiros: Hippeis Thessalikoi
*Athens: Epibatoi Peltephoroi, Epibatoi Hoplitai
*Tyrrhenoi, Poeni: Dorkim Aloophim
*Tyrrhenoi: Etrurian Greataxes.
*Sparta: Morakoi Hippeis
*Odrysioi: Thureophontes Hippeis
If the Noble Residence trains mercenaries, they should generally have better armour and HP.
*Katoikia - stock Nob Res for Greeks and other factions, but isn't available until the Classical Era.
*Syssiton - Level 1 Blue, Level 1 Red - Built by Sparta and Epeiros.
*Warrior Hall- Level 1 Strategy. Built by most other factions that do not have access to either Oikoi or Syssitia. 
The Tokharoi use a system that is based on tht of Rise of Kings as opposed to Kings & Conquerors or Warbirth.
