I have heard that there will be craftable items for housing but something I thought would be a great idea would be to have craftable items from all professions. Here are some examples of what I was thinking:
Alchemy: Alchemy displays like a table with potions, mortar and pestles, and alembic.
Blacksmithing: Sconces, braziers, candelabras, chandeliers, etc.
Clothier: Rugs, wall hangings, drapes, etc.
Enchanting: Welkynd stone lamps, enchanting table displays, etc.
Woodworking: Tables, chairs, etc.
Provisioning: Feast and food displays. Fire pits or cooking displays.
Style components could be used for racial based furniture. Maybe rare monster items could be turned into trophy displays.
