If this opening round of voting has proved anything, it’s that ARCHITECT readers are steadfast in their decisions ... for the most part. In nearly every match, the outcome hovered around 70–30 in the voting (see below). Well, all except one.

The match that had us on the edges of our seats watching the final tally come in was Johnson Schmaling Architects’ Linear Cabin, in St. Germain, Wis., versus Lake|Flato Architects’ Hog Pen Creek Residence in Austin. The two projects are similar in form and intention: Their horizontal layouts feature ample windows that take advantage of the natural environments that the owners wanted to enjoy. The delivery in both were so successful that they each won different national awards from the American Institute of Architects: Linear Cabin won a 2016 Small Projects Award and Hog Pen Creek Residence a 2016 Housing Award, respectively. They’re also both situated next to lakes. The similarities between to the two are so uncanny that perhaps that’s what kept the competition so close. In the end, however Hog Pen Creek Residence trudged ahead, and will move onto the round of 16.

Now you know the drill. It's time to compare the remaining 16 in the brackets below. Let's see if these choices will be a bit more challenging for our ruthless readers!

Voting for this round will close on Wednesday, March 22, at midnight EST.
