Creating new buildings?

[Rudovich]

I can create new units in ETW and tried to create some buildings on it just before NTW got released. It failed and want to continue it on NTW, but again it fails.

I have got plenty of ideas and a few of them are ones everyone can use like tax roads, hospitals, prisons and I would place in fishing villages again. I also have some ones that would be in just one city like Vienna General Hospital in Austria and the Russian Admiralty in St Petersburg. many more

so can anyone tell me on how to do this? I editted those files and it seems not to work:
building_culture_variants
building_discription_variants
building_effects_junction
building_levels
building_upgrades_junction

You forgot the building_chain_to_slots, building_chain, and building_description_text(If you decide to add one or it will be blank).
