» The $2.2 million Blackstone Knoll, a GreenSlate project, will add three loft apartments and nearly 6,000 square feet of retail and office space on a hilly spot southwest of 39th and Farnam Streets. Rising out of the ground now, the two-story Knoll should be done next spring.

» The Blackstone Corner project will offer 12,000 square feet of commercial space and is to be done in 2019. It seeks up to $2.8 million in tax-increment financing, according to city documents. Similarly, the Knoll and Depot projects request TIF to offset costs such as acquisition, demolition and public improvements.

The trio of new construction projects fuel a commercial district awakened after a photographer took a risk and opened his studio on the corridor. Brad Iwen was joined by Lund and Matt Dwyer, who rehabilitated a cluster of bays northeast of 40th and Farnam and continued on a roll.

GreenSlate says it and Clarity have led investment of about $85 million in the Blackstone neighborhood, including the newest phase.

According to Dwyer’s unofficial calculations, other developers have contributed an additional investment of $55 million in the neighborhood generally bounded by 36th, 42nd, Dodge and Leavenworth Streets.
