The add-on doesn't seem to be as expansive as Dawnguard, with entirely new locations and quests. Rather it focuses on purchasing land and designing, building and maintaining your own home.
Once a suitable plot of land has been bought, a drafting table and carpenters workbench allow you to design and craft every section of your home, room by room. Each room can be given a specific purpose - such as a library, armory or enchanting and alchemy labs. A wide range of furnishings are also available, such as divine shrines, stuffed animals and display cases.
Not only will the add-on feature building a house, it can be transformed into a home by adopting children with a new adoption mechanic. The option to hire stewards and a personal bards is also available. Owning a home comes at a price however, as you will need to protect it from Skeever infestations and Giant attacks.
Hearthfire will be available for download for 400 Microsoft Points on Xbox LIVE on September 4.
