Stick a pin in the northwest corner of your US map. Holland Partner Grouphas threemultifamily projects under way onDexter Avenue in Seattle,andCEOClyde Holland tells us he found the new residential hotbed by following bicycles. (We like to imagine he was wearing roller blades and just grabbed on to the seat.)

Our theory would explain the helmet. Overall, Holland has five new multifamily projects under constructionin Seattle; three are on Dexter Avenue, just west of the Amazoncampus (we imaginethose book-pushers are also avid cyclists). Clyde and a few associates were dining at McCormick's a decade ago when they noticed that every bike they saw was cuttingdown Dexter, then a mostly industrial/parking lot area north of the CBD. Intrigued, they went to have closer look at the quiet area within walking distance of LakeWashington and knew they were on to something.

Here's the Dexter construction zone today. Unlike the rest of SouthLake Union, which has Amazon.com-ified (trust us, it's a word) during the past several years,Dexter remained much the same. Holland's buildings will allow residents to takein the city skyline from their large roof gardens and take advantageof downtown living without owning a car. The first building, Union SLU, opened in October, and another, Hue, opens next month. A bigger sign that Dexter is about to explode: Capstone Partners and Stockridge Capital Group recently announced plans to do a spec office building, titled Dexter Station, near Holland's projects.

Holland COO Tom Parsons and development associate AllisonShephard show off the view from the roof garden of Union SLU. (That's not our flash. They took the photo just as a meteor was landing.) Holland started 3,000 units in 2012, all Gen-Y, core urban infill stock in Denver, Portland, and SoCal. He's holding off on anythingelse in Seattle for the moment because construction costs (and rents) are starting to spike, possibly signaling an end to Seattle's multifamily development binge. When Clyde's not in the office, he can be found working on a different kind of housing problem: At the impetus of his son, Clyde founded Share Housing, a nonprofit that provides transitional housing for working people who are homeless.
