There are some amazing houses at U of Washington. Here's the SK house someone else mentioned - it really is adorable.

And the Chi O house is HUGE. Supposedly it's the largest fraternal structure west of the Mississippi! One of my sisters is the house mom there, so maybe I'll beg a tour from her some day. ;)

While this house isn't big, it's gorgeous, and it's at a really small school called Widener University in PA. This D Phi E house is beautiful, both inside and out!

Oh...okay. Thanks!!

Our house is shaped as the letter Z for Zeta. :)

The rest of my house!!!
 

Well since zz-kai- posted pictures of MY house I thought I'd share the site for our Virtual House tour. It's a little tricky to navigate, but goes through most of the house. See if you can get out to our deck on the third floor (unfortunetly it doesn't show the views that we have from up there...)

Start the Nebraska Beta house tour

The Tri-Delta house at the Univ. of Ala. is kind of circular in shape. The other neat thing about U of A is that all of the sorority houses are on one little street near the football stadium. This makes it feel like its' own little neighborhood.

shadokat, there is a house in my old neighborhood that looks EXACTLY like that! :)

Oh, looking at all these gorgeous houses makes me so jealous!! At my school, the sororities didn't have houses...Blue Laws and all...:(

my chapter houses' doors are hand carved with our letters (chi omega)..they were featured in chi omega's centennial book..they are incredible

also on my campus(u. of new mexico) the kappa house is in the shape of a key(arial view)

The Alpha Delta Phi house here is shaped like a cross.

Also, almost every house here had an addition put on in the late 60's, and it is very obvious. You can look at them and see how the house was perfectly symmetrical, and then someone added a chunk.

My chapter is the only chapter of Alpha Gamma Delta with TWO chapter houses, they are side by side and we share a parking lot.

The ZTA house at UNC Chapel Hill is a Charleston-style home where the building is deeper than it is wide and has a porch along one side with a doorway to the porch from the street and then a front door from the porch. The Kappa Sigma house at Auburn University is supposedly an architectural marvel, kind of a throw back to Frank Lloyd Wright. Many architecture students at Auburn go to the house to sketch and study the house.

Sigma Kappa at the U of AZ has a spiral staircase too. I hadn't heard that most do, but you can add us to your list!;)

The SK's here don't have one, to the best of my knowledge.
