where do i find it? On UESPWiki is says: "You must purchase the land and use raw materials at a drafting table and carpenter's workbench to create rooms and furniture for your house" So from who do I purches land and where do I find drafting table and so on?
They will be onsite when you buy the land. The chest will have the basics needed to start. I think the only things you have to buy vs looting or making is the lumber, glass and straw. At least i have never found glass or straw as part of loot.
