Outside of the solar PV- and green roof-ready home, you’ll find drought-tolerant landscaping and permeable paving. There's also a one-car garage that can be converted into a home office, workshop, or mother-in-law apartment. And while we're on the topic of mother-in-law apartments, it's worth noting that Cascade Built founder Sloan Ritchie is also behind Backyard Boxes, a line of eco-friendly accessory dwelling units that I featured back in May 2010.
And, of course, there’s the matter of neighbors. Alley House 2 is located right next door to Cascade Built’s original Alley House, one of the first LEED Platinum (non-modular) homes in all of Seattle. That said, Alley House 2 is only the second modular home in Washington to target LEED Platinum certification (Greenfab's 1300 Series model home in Jackson Place was very recently awarded with LEED Platinum certification making it the first). I guess the home’s “Platinum Alley” address is totally justified (the actual street address is 216-B 26th Ave. E).
For more, check out Alley House 2’s official listing as well as this photo walk-through over at Curbed Seattle. It's also worth checking out a series of photos of the home's installation over at the Cascade Built Facebook page if you've never seen photos of a factory-built modular home be "dropped" before. Beyond LEED Platinum prefabs, Sloan Ritchie and the CB team also have some interesting homes in the works including a Passive House project in nearby Madison Park and four homes for the Clearwater Commons green co-housing development near Bothell.
