BadLuckBurt for the building and block files extraction.
Arneb_Nihal for the location files extraction.
The World Data Compendium contains all of Daggerfall's buildings, blocks (both RMBs and RDBs) and locations to jumpstart editing the game's world and dungeons, including the ones that are unused in the game. The building and block files can be opened with the World Data Editor and RMB editor while the location files can be edited directly using Visual Studio Code.
Enjoy and I hope it helps you work on awesome mods that change the game's world!
