If you, like me, are interested in green building, live in the Seattle area and always have your ears perked up for a good party, I’ve got a scoop for you.

Wednesday, CascadeBuilt debuts its Alley House (at left) in Madison Valley at a free open house. It’s at 222 26th Ave. E., Seattle, and runs from 5 to 8 p.m.

I wrote about the Alley House at the end of June in the DJC here. In case you missed it, it’s a pretty interesting project. The house itself is going for LEED platinum through your usual green suspects… SIPs, healthy finishes, solar heating that pre-heats water etc.

In Seattle, LEED platinum houses are still pretty rare - there’s only two (so far) in the Seattle area… Ashworth Cottages and Mike Mastro’s personal residence (more on that in the DJC next week).

But what I found most interesting about the project was the developer - Sloan Ritchie. First, the Alley House is infill and was built in Ritchie’s back yard. Second, Ritchie has only been a developer for three years (wireless engineer before that). Third, he talked about LEED platinum not at all being the pinnacle of green design, but rather the best he could achieve at this time. His goal, he said, is to keep pushing each project further. I hear this a lot from big firms but it’s a whole different story coming from the little guy. Next up (at some point) will be a netzero project.

To RSVP to the open house, e-mail 222@cascadebuilt.com. To learn more about the project, visit its Web site here. To read Ritchie’s blog on project progress, go here.

P.S. It’s priced at $770,000. Also, if for some reason you can’t make it Wednesday, there will be a Greendrinks tour of it on Aug. 23 (more here).
