So if you build something medievil and want a lot of details snack yourself the Conquest ressource pack. With it's meta datas you have around 200 alternative textures for blocks = For example ID 30 is cobweb, 30:1 is a bottle (Which has 3 alternative textures + 2 textures for other biomes) It takes a while to get used to it but once you have it you wont ever let it go again.
Also a tipp on building. Don't get to much! If you are building alone think of something small that you can enhance with the time. If you have a plan of 50 buildings you will most likely lose interest at the 15th. So maybe first build a tavern some houses and a small market and enhance your build afterwards.
For my project I created 4 districts - Kathedral District, Mage District, Harbor District & Poor District. - Buildings: Bakeries,Blacksmiths,Taverns,General Goods, Bank, Kathedral, Castle, Ship, Market with stands, Mage Tower, Statues, Graveyard, Docks, City Walls and Towers aswell as a shipyard. Should be enough inspiration for you ^^. If not check my project site on my profile for more than only Human builds
Sorry for my bad english and the long text I hope it helps See you around and good luck on your project
