An Open and Airy Backyard Cottage

A 1920s Crown Hill bungalow gets a new, green backyard abode

Developers have been drooling over Kate Lichtenstein’s property.  Located in a neighborhood filled with small houses, many of which are being torn down, the lot includes her beloved one-story, one-bedroom 1920s bungalow and until recently, a small, dilapidated shed in the backyard. “I get letters all the time from developers wanting to buy it,” she says, “but I think it’s such a unique property and I plan to hold on to it.”

As a part-time musician, Lichtenstein a was toying with the idea of replacing the shed with a slightly bigger studio when events conspired in 2010 that allowed her to set her sights on something grander. Not only was Seattle’s new backyard cottage ordinance passed (legalizing the construction of accessory dwelling units, ADUs, in the backyards of single-family-zoned lots), but a friend had just told her about a local architect, Tim Hammer of Cast Architecture. Hammer, an early backer of Seattle’s cottage movement, is known for designing clever small spaces. “It’s always been a core interest,” Hammer says. “My first home was a 550-square-foot fisherman’s shack in Ballard, and I spent 18 months in Kobe, Japan, studying high-density housing. The craft of small space design is: How do you make it feel open, comfortable and airy, and not claustrophobic?”

The kitchen is awash in salvaged fir, from the roughly finished ceiling made of car decking to stair treads reclaimed from Ballard’s Sunset Bowl to the custom cabinetry

Hammer’s 550-square-foot answer to that design query, completed last year, sits in Lichtenstein’s backyard. The two-story, rustically modern cottage, which seems far bigger than its measurements, comes with creature comforts that include a loft bedroom, full kitchen and bathroom and green-design bells and whistles. With its long-lasting metal roof, LED lighting, superefficient boiler heater, low-VOC paints and caulks and radiant floors of fly-ash concrete (a by-product of burning coal for energy), the cottage was built following 5-star Built Green requirements.

“The exterior envelope is a combination of 2 inches of rigid insulation with wall cavities filled with an additional 5 and a half inches of cotton insulation from recycled blue jeans,” Hammer says. “The spec on it, in terms of being sustainable, is beyond most projects that I’ve ever worked on, and that was really driven by the client.”

Lichtenstein, who works for Sound Transit and has a background in sustainable design (she’s project manager for the University District’s new light-rail station), used recycled materials such as the resplendent reclaimed fir used for its beams, posts and stairs, and the Craigslist claw-foot tub in the bathroom. “I really love the picture of modern design that incorporates salvaged materials,” she says. “It’s also fun to find really simple solutions for things.” For example, discovering a new use for galvanized electrical conduit. “It’s supercheap, like $1.65 for a long section,” she says, “and I thought that was a great material to form the loft’s railing.”

The bathroom is one of this cottage owner’s favorite spots. “It’s really open and bright,” Lichtenstein says, “I love the raw concrete, all the imperfections. I think it’s just beautiful.” Lichtenstein found the claw-foot tub on Craigslist and had it refinished. The shower curtain track is another version of the cheap electrical conduit tubing featured in the loft bedroom’s railing

“I’m really happy I did it,” Lichtenstein says of the project. “I’m not against redevelopment, but this was a way to redevelop in a different way.” While enabling her to preserve the main house, the cottage offers untold flexibility, including the option of serving as a rental unit.

Or it can serve as the studio she originally imagined. Lichtenstein is part of an old-timey music trio, The Barn Owls (, that performs at local bars, including Conor Byrne Pub, and square dances. Says Lichtenstein with a laugh, “The cottage is a good place to get away to when you’re learning some screechy fiddle tune.”

AIA Home: Goodbye 1970

Family fixes design flaws to bring midcentury home into modern era

“Treehouse” by Floisand Studio Architects returns to glory a Ralph D. Anderson home that had lost its compass. Nick and Rachel Lenington purchased the 1970 Mercer Island home in 2010, attracted to the quiet neighborhood because of its midcentury vibe, big, west-facing windows, and abundant wildlife. An advertised water view didn’t really pan out, but…

Living: This Kitchen Really Cooks

Remodel preserves Victorian charm

Raised on an off-the-grid ranch in southern Oregon, Mandy Lozano took a don’t-fence-me-in approach to renovating her kitchen in Seattle’s Squire Park neighborhood. She sought to balance a respect for the 1900 Victorian’s heritage with a genetic predisposition toward creative license. “I don’t care for modern technology that much, and I don’t like fussy or…

It Costs What? High-End Seattle-Area Homes Skyrocket in Price

The rise in pricey homes throughout Seattle is nothing short of astonishing

It’s no secret that housing prices are skyrocketing. Some new numbers, however, may send you into a fit of apoplexy. A study by home buying and selling service Orchard finds that the Seattle region has experienced a whopping 180% increase in the sale of million-dollar homes in just three years. So far in 2022, almost…

The roof slopes to the south for greater solar-panel efficiency and the one-car garage was among several tradeoffs to improve energy efficiency.

Seattle Passive House Respects The Environment

Passive House in Ballard treats the environment with respect

Rade and Eli Trimceski didn’t set out to save the planet when they commissioned their new home in Ballard, but the planet sent its regards anyway. Designed and built by First Lamp Architects of Seattle, the project was named the Passive House Institute U.S. (PHIUS) National Home of the Year in 2020.  Billed as “the…

Why This Tiny Cottage in Shoreline Works For a Family of Four

Why our tiny house makes sense

We live in a world full of hacks, loopholes and workarounds that often lead to more work and dead ends. When my wife, Kristy, and I discovered a way to live mortgage free, it seemed too good to be true. There had to be a catch. Six years later, we are still living out that…

The project resulted in an extra 5,000 square feet of floor space and a refacing of parts of the facade.

Seattle’s Former Columbia Congregational Church and Allied8: A Match Made in Heaven

The former Columbia Congregational Church was in disrepair before architectural firm Allied8 came to the rescue

The Columbia Congregational Church was harshly thrust into an uncertain future in the secular world.   It was founded in 1891, two years before the Columbia City neighborhood. The densely forested site was ringed by marshlands and served as the gateway to the untamed Rainier Valley. At the time, it was a common practice to donate…
