I don’t know how I completely missed this project but Tom Kundig has designed a building going up South Lake Union (just north of REI) called the Art Stable.
The building is a Point 32 project and is under construction and has pre-sold 4 of the 5 units which are being sold as unfinished shells. The last remaining unit #600 is 2,300 square feet and listed as a for-sale-by-owner on Zillow at $1,850,000. Sadly, out of my price range, this is exactly what I want!
