Born in Germany, Andrew Willatsen immigrated to the U.S. in 1900 and soon after found his way to Frank Lloyd Wright's studio in Oak Park, Illinois. After working under the architectural master for three or so years, he moved to Washington and formed a partnership with Francis Barry Byrne, another FLW disciple. They soon got to work supervising the construction of the Seattle Golf & Country Club at The Highlands and also designed the 6-BR, 5.75-bath estate at 105 NW Highland Drive, which just hit the market asking $3.4M. Known as the Charles H. Clarke House, this 1910 Prairie-style view home boasts strong horizontal lines, deep eaves and natural materials. It's also evident inside as you get lots of open, flowing spaces, which wasn't the norm of the Victorian-dominiated times. Looks like there's also a recently-renovated guest house right next door as well. You're also getting 3.85 park-like acres that include tucked-away gardens, greenhouse and the requisite sport court. Some folks may know this place as Todd House after longtime owner E.E. Todd. Whatever you call it, it's a piece of Pacific Northwest architectural history.
