New spec house in Issaquah Highlands

We’ve completed the first community design workshop for the Sunset Substation pocket park and we’ve started a blog for the project at www.SunsetSubstation.org.  The results of the workshop are posted here and you can read a write up from the Ballard News tribune here and another article from KOMO’s neighborhood blog here. Now that we have some community input, we can start shaping their unique goals for bringing solar power generation and community space together.

In other news, Stefan is working through designing a micro-hydroelectric generation station for an eco-retreat/outdoor recreation center and meditation retreat in Colorado, and should be posting an introduction to the project and more information about micro-hydro.  Suddenly, we have a lot of projects which have some active or passive alternative energy components–very exciting stuff.

Tim is leading the charge on backyard cottages.  We have two custom cottages currently in design, and another design which will be available as a prefab.  We’re finalizing the pricing, so we will have a more comprehensive information available soon.

We’re also working with a homebuilder  to develop a series of spec homes bases on a fusion of asian design, modern spaces and out of the norm materials (see image above).  We’re especially excited because the house’s function emphasizes a series of landscapes integrated into living spaces, so we’ll have courtyards, pocket gardens, and salad gardens for growing your own vegetables off the kitchen.  Our big presentation is on Tuesday so I’ll post the schematic renderings afterwards.

Finally, this is the last weekend to see our WASTE NOT installation in the alley east of First Avenue, south of Occidental Park.  Anyone need 2500 2 liter bottles?

Here’s another new project in the office, an addition to a residence on Capital Hill. The existing house is a tiny 750 sq. ft. bungalow on one of Seattle’s steepest streets. The owners found the compact plan a perfect fit when they first moved in, but two kids later, they desperately need more room. They are drawn of the core values of modern architecture – emphasis on natural light, spaces that flow together, honest and straightforward materials – and want a house that expresses that. They are comfortable making a pretty bold statement, but they also want the addition to feel comfortable in the existing fabric of the neighborhood. They are interested in sustainability that is designed in from the ground up, which led to the early decision to preserve the existing structure instead of starting from scratch on the site.

How to add onto an existing building that has a well-defined or historical style is a perennial architectural puzzle (and hip roofs are especially difficult to achieve seamless integration). In this case, we approached it by creating a clear contrast between the new and the old through form, material and color. But it’s not enough to just plunk a contemporary form next to an old house and expect a real conversation to take place. In this addition, the new and old talk to each other both in how the volumes intersect and in how the two differing styles overlap.

We are very excited to begin a new project for the Sunset Hill neighborhood to transform an abandoned City Light substation parcel into a pocket park.  Based on the input from the community thus far, the program is very intriguing:  a community space with an artist-in-residence caretaker, powered by a serious photovoltaic array.

There may be more or different elements as the project evolves in the community design process, and as we navigate through various City agencies and funding sources, but fundamentally this has all the values we expound as a firm:  sustainable building, energized public space, housing options/density, and  an interactive process that invests people in the civic life of their neighborhood.

In 2008, I designed a structure with a similar program for a Dwell Magazine conceptual competition:

p-patch-book-cover

We are very excited to see this survey of Seattle’s urban community gardens, especially since the Interbay P-Patch is included as one of the case studies.  The P-Patch is one of my personal favorites because of the impact it has had in strengthening this vital community, and has been instrumental in showing other neighborhoods how to implement their own community garden.

Further, the P-Patch really showed us just how satisfying working on these small pro bono projects can be. Since the P-Patch, we’ll donated about 5% of our yearly output to pro bono causes, including daycares, parks, and community centers and hope that we’ll have more opportunities to help concerned citizen groups visualize and build a better city.

alley

The big opening is tonight from 5 to 9, between 1st and 2nd just south of Pioneer Square–

Yesterday we hoisted the installation in place. While we still have to do lighting, the impact is great! From the end of the alley, the installation looks like a lonely cloud hovering there, and only once you get beneath it can you see the message “WASTE NOT.”

alley installation--in process

alley installation--in process

We are working on a collaborative art installation for the Nord Building’s upcoming Alley Party, sponsored by two non-profits, Feet First and the International Sustainability Institute.

Feet First is an advocate for walkable communities, and ISI works on documenting global best practices for urban sustainability.  They have been working with their neighbors to transform alleys from nuisances to assets. Part of the program to invigorate the alleys as a vibrant urban places is their Alley Parties.  Each one incorporates art, music, food and drink to draw people into the alley and give people a different perspective on what they can become.

This Thursday, CAST, in collaboration with Christopher Ezzell of E Workshop, and Vashon Island artist Shahreyar Ataie,  will open an art installation that will float over their the Nord Building’s section of alley, using about 600 recycled 2 liter bottles.   It will be up through the New Year.

So come one and all!  Did I mention there will be food, drink and music?

Alley between 1st and Second, just South of Occidential Park

314 First Avenue

November 3rd,  from 5 pm to 9 pm

house

Greenwood resident Kate Lichtenstein contacted us last spring to help her design a backyard studio / guest house for her modest 650 square foot 1920’s one bedroom home (shown above). While the home’s scale fits nicely with Kate’s desire to have a simple and ecologically responsible lifestyle it falls a little short when it comes to a rough and ready workshop space for art, bicycle repair, ski tuning and building projects. Kate’s home also lacks the space for a home office / guest room – something that she would like to integrate into the new structure.

Our initial goal was to have her project under construction by late summer 2009 but we were unable to get the project off the ground by that time. In hindsight, the stalling of the project turned out to be a stroke of luck…

In March of 2009 Seattle Mayor Greg Nickels proposed legislation that would allow Seattle homeowners to construct backyard cottages on their property. The legislation was reviewed and ultimately passed by the Seattle city council on November 2nd 2009 (with a 9 to 0 vote too! Kudos to Seattle voters for electing progressive urbanists for city council members!).

For Kate the ordinance has opened up new possibilities for a structure that can both accommodate her current needs and provide a potential source of income as a rental unit if her finances ever fall on hard times. Besides allowing for a legal detached rental unit the ordinance also allows for the construction of a two story structure – an arrangement that will work well for Kate’s needs and will help to preserve the spaciousness of her backyard.

Kate is planning to build with a mind toward sustainability and has a special interest in using recycled building materials whenever possible (she is, at this time, planning to write a parallel blog on the topic of recycled building materials). For us at CAST architecture Kate’s project is an exciting chance to test out the new backyard cottage ordinance and work with a client who is committed to building green. We see her project as an excellent opportunity to provide the general public with information about the process of designing and building a backyard cottage in Seattle. Kate and her partner Ric Cochrane are always game for an adventure and have graciously agreed to allow us to share their experience with you. To that end, we are planning to blog about Kate’s project as we travel through the design and construction process. Please subscribe to our feed if you would like to follow along in future posts…

This is a photo I noticed on Kate and Ric's fridge during my last visit. I felt it was a great visual summary of their adventurous spirits and the fact that it was held up by magnets that say "reduce, reuse, recycle" and "save water" was singular! The photos were taken during a cyclocross race last summer - Kate is on the left and Ric is on the right.

With the impending vote on the backyard cottage ordinance, everyone in the office has been doing a little daydreaming about the DADUs and what they would build.  I have been working on a idea that started with a little ink drawing. It’s now developed into a preliminary model/floor plans.  I’ve flipped the shed roof to have more volume in the shop/studio and worked out the bathroom so that my shop could easily be converted into an open kitchen/living space.

I have also been working out a simple steel structure, clad with structural insulated panels for easy construction and minimization of waste.  The goal is prefabrication of the components offsite, then assemble.

I’d love to try out using a geothermal pre-heating loop, with a hydronic radiant system run of a domestic hot water heater and test the new PV shingles, but that might get a bit expensive.

This product isn’t new, but new to us:  sheep wool insulation.

Sheep wool insulation has some advantages over other forms of insulation, especially fiberglass batts.  It stays lofted, retains R-value even when there is moisture penetration.  It installs like fiberglass batts, but there are no masks, no off gassing, no itchiness.  Plus the product is all natural, and there aren’t the environmental impacts of making fiberglass.

There are a couple big downsides:

1–this is not a local product, and there are carbon costs associated with bringing the insulation to our neck of the woods (although bringing together the elements to make fiberglass isn’t carbon free either)

2–the cost is about $2.16 per sf, which is roughly three times the cost of fiberglass, or 50% more than spray foam.
