The Jarl's Longhouse in Falkreath is another well known spot.  There's the quest you can pick up from the Jarl to deal with some bandits which will then lead to the ability to purchase the land Lakeview Manor is on.  Do a few more things around Falkreath and the Jarl will make you Thane.  Now, the Jarl changes depending on at what point you're at in the main questline.  If you get there early, the Jarl is Siddgeir, who seems rather foppish, is more concerned with riches and wealth and making deals than anything.  Should you get there after the big meeting in High Hrothgar, the Jarl is Dengeir of Stuhn.  Dengeir seems a bit more pragmatic though he tends to be paranoid, and while a supporter of the rebellion, he actually has doubts about Ulfric.

As far as building the actual longhouse, this one took up just as much kit bashing as Deadman's Drink.

Probably the biggest difficulty was the stairs on either side of the building, as the base editor doesn't exactly give a whole lot of options for long stairs.  As for things like the throne, that was simple enough though the base editor only gives three options.  Same with the banners and the symbol, while close, is not just antlers.  You can take a look at some of the examples below.

Stay tuned for another interior.  This one's very simple compared to the longhouse and Deadman's Drink.  It's the interior to Gray Pine Goods.  Sadly, none of the witty conversations with Solaf can be recreated.  And sadly no interactions with his overly racist brother who happens to run the saw mill.
