"High end Loft Stuff" is the second expansion for Sims 3. As you can see "High end Loft Stuff" and "Fast Lane Stuff" aren't Expansion Packs because they don't give you anything... just furniture.
This expansion gives you some modern and luxury furniture and you can even furnish a full house because it has several furniture in each category.
If you try to find more information about this expansion in Sims 3 lessons I guarantee that you won't find ANYTHING because it has just... furniture.
