Mazama Public House at the north end of Washington’s Methow Valley

mazama public house in the Methow valley community

The Mazama Public House is set to become the gathering spot for the community of Mazama, at the north end of Washington’s Methow Valley. Oriented toward Goat Peak mountain views, the 1,868 square foot public house is designed to seat 56 and another 50 outside with built-in benches on the four-season covered patio.

An expansive three-door door system opens in the summer months for a seamless connection to the outdoor decks. The indoor area incorporates performance space, and the large garage doors allow for flexibility and increased seating capacity. The height of the shed roof and the expansive windows on two sides are sited to take advantage of natural light and views. The interior features wood beams punctuated by blackened steel and concrete floors. Custom tables and bar slabs were crafted from locally sourced Douglas-fir. Outside, blackened steel will accent the wood structure. The siding is a dark-stained, rough-sawn vertical channel shiplap.

Feasibility and design in early learning education

Our region is suffering from a significant childcare shortage. The Washington Child Care Collaborative Task Force estimates the total childcare capacity in King County has declined by over 25% since the beginning of the Covid-19 pandemic. This created wide-ranging consequences throughout the economy, delaying the ability of parents to return to full-time employment. As the direct impacts of the pandemic fade, many childcare providers now seek to increase their capacity either through construction of new facilities or expansion of existing ones.

 Early Childhood Education (ECE) is governed by sets of overlapping regulatory requirements. This article aims to provide a brief overview of some of the most important considerations in feasibility and early design phases.

Building-scale Considerations

There are important features inherent to the space itself that cannot be easily added. These requirements must be factored into the cost model for construction, and into a decision for leased space. The following is based on the requirements of the Washington State Building Code (WBC) and the State of Washington Department of Children, Youth, and Families (DCYF) Childcare Licensing Guidelines.

·  Childcare centers are typically a Group-E occupancy; sprinklers are required. Lack of sprinklers is a common red flag in early feasibility analysis.

·  Classrooms for children younger than 30 months must be on the ground floor and must each have an exit door directly to the exterior. Classrooms for children between 30-60 months in age may be no higher than one story above grade and may share common exit pathways. 

·  It is important to verify the proposed space will comply with the requirements of Chapter 5 of the WBC. Group-E occupancies have a smaller allowable area and higher occupancy-separation requirements than other uses in the same type of construction.

ECE Center Considerations

DCYF will license a center for maximum number of children, based on an operating plan that maintains certain ratios of adults to children all times. It is important the design does not unintentionally reduce the allowable number of children or increase the required staff count by misinterpreting DCYF regulations

·  One important example is the minimum area per child. The WBC sets out an Occupancy Load Factor of 35 s.f.; the parallel requirement under DCYF is also 35 s.f. per child. However, DCYF only considers space that is accessible to children at all times. Areas of the room that are considered occupiable under the WBC - such as a teacher’s work desk or a locked cabinet containing art supplies - are excluded from DCYF’s area calculations. 

·  A classroom for 20 children must be designed for at least 22 or 23 persons, since the adult caregivers must also be included in the calculation. For feasibility planning, we have found that if we assume 50 s.f. per child, the final design will comfortably accommodate the planned student count.

·  A minimum of 75 s.f. of outdoor play areas must also be provided, and this area must also include the caregivers. While a single play area can be shared between multiple classrooms, large centers will need to carefully schedule such shared use. Creative alternatives such as walking to a local park may substitute for dedicated outdoor play areas, but these require increased staff levels and are reviewed on a case-by-case basis by DCYF.

·  Current DCYF practices require a large number of plumbing fixtures.
- Separate single-occupant restroom(s) for adult use
- Child toilet rooms with child-height sinks and toilets; with both assisted and semi-private toileting
- Adult-height handwashing sink at building entrance
- Child-height handwashing sinks at each classroom entrance
- Bottle-fillers at each classroom and at outdoor play area
- Adult-height handwashing sink at food distribution area, even if food is prepared elsewhere
- Adult-height handwashing sink at diaper-changing areas within arm’s reach of changing table

·  Kitchen facilities must be carefully considered in the center’s plan for operation. While ECE kitchens are generally not required to be licensed as commercial kitchens, DCYF personnel review them using Department of Health guidelines. 
- Use commercial-type refrigeration with continuous temperature display on the exterior.
- Any on-site food preparation beyond distributing pre-prepared items on disposable plates will require a dedicated kitchen space with separate hand-washing, food preparation, and three-compartment dishwashing sinks.
- Some types of hot food preparation can be accommodated with residential-grade cooking and ventilation equipment, this will significantly limit potential menus. Any operations utilizing grilling or frying will require installation of a full Type-II commercial range hood. This can be impossible in a space not designed for it from the ground-up.

Classroom-level Considerations

Good design can help reinforce the mission of the center. This covers a lot of potential ground, but here are a few areas where we often focus attention:

Clarity of wayfinding is critical for young children and is often a challenge within an irregular tenant space. If the layout must be complex, color, lighting, and material changes can give each group of classrooms its own identity. Larger gathering nodes outside classrooms can accommodate busy student dropoff and pickup.

Many designers associate ECE with bright primary colors; keep in mind, that classrooms will be filled with a huge variety of educational materials and children’s projects in a rainbow of shades. Letting the architecture create a clean, muted backdrop helps organize the inevitable chaos.

Understand the routines of a child's day and let those guide your design. Snacks and meals will be served and eaten in a certain way. If the classroom doesn't have a designated place for folding or stacking mattresses, they will take up a corner of the room that is not available for playtime. If a cozy space for reading or quiet play isn't inherent in the geometry of the room, create one with casework, furniture, or a change in lighting or ceiling height.

Many different elements must be balanced to achieve a successful ELC design. Details aside, the most important element is to really get to know your client and their operation. It is hard to go wrong by listening carefully to the teachers who spend all day in the classroom.

Central to the name, identification and restoration of wetland habitat was central to the Rainier Beach Urban Farm & Wetlands. The location of all site improvements, including agricultural fields, buildings, roads, parking, and other farm infrastructure, was dictated by the need to not only avoid riparian zones, but to facilitate their enhancement. Rather than treating this as a limitation, our team of Landscape Architects, Architects, and Civil and Environmental Engineers used the wetlands at the center of the site as an organizing principle that strengthened the project.

Finding the right place to build the Icicle Creek Retreat within a 22-acre private inholding in the Wenatchee National Forest required a careful and deliberate process. CAST worked closely with a wetland biologist and a geotechnical engineer to identify a buildable site, triangulating between several types of stream and wetland buffers, geological hazard areas, location of access roads, and forest fire safety concerns. The project required both SEPA review and Conditional Use Permit approval through the Chelan County Hearings Examiner.

The Port Gamble S’Klallam Tribe Hatchery Building is located on the beach in a known archaeological site. CAST worked closely with the Tribe’s Cultural Resources team to develop an amendment to the Tribe’s Archaeological Resources Protection Act (ARPA) permit and to incorporate the resultant Monitoring and Discovery Plan (MDP) into the project specifications. Located in the intertidal zone, the design required close coordination with Structural and Geo-Technical engineers to ensure that the building will be resistant to higher tide levels predicted to occur with rising sea levels.

matt hutchins, AIA, PHCD, INVITES CITIES AND TOWNS TO ZONE AND DESIGN FOR THE FUTURES THEY WANT

TAKEAWAYS

• Seattle has concentrated several decades of population growth within narrow corridors of the city, disproportionately affecting poor and BIPOC communities while failing to ask nearby detached-house areas to evolve and grow as well.

• Cities and towns with rising housing costs can address home shortages and inequities by opening up their zoning to new design options, as proposed by a middle housing bill that Washington state leaders are currently considering.

• One such design: the Seattle Six, an attractive, economical, adaptable design that enhances neighborhood vibrancy and prioritizes quality of life, environmental responsibility, and anti-displacement. Cities and towns elsewhere can imitate or design their own such solutions.
  

If you want a healthy garden, you don’t blast just a couple plants with the hose; you water everything slowly so the roots can soak it up. Same with a city or town: sprinkle some housing everywhere, and you’ll get healthier neighborhoods.

Under Seattle’s Urban Village Growth Strategy the city has funneled 25 years of growth into tightly designated areas without asking adjacent detached-house areas to evolve as well. Along with America’s decades of racist redlining, car-centric design, and the primacy of detached-house building, this kind of strategy has limited what our cities can be. It has sent home prices skyrocketing, deepened racial inequities, and failed to address climate change in how we build our communities. Certain “gentle density” solutions like backyard cottages and townhomes have expanded housing options in tight markets, but for metro areas, the need is greater than these alone can address.

Fortunately, Washington legislators are currently considering a powerful “missing middle” housing bill that would open up a host of modest-sized housing options for people across the state while delivering numerous other benefits for communities. They are reworking zoning rules to empower us to build the future we want. And they are making it possible for architects like me to creatively contribute to the suite of design solutions that can help address the multiple challenges our cities and towns face.

INTRODUCING THE “SEATTLE SIX”

As an architect, I see how zoning regulations, good and bad, directly shape the design of buildings. Right now, there is a once in a generation opportunity to conceptualize the next basic building blocks of our towns and cities, starting from a set of key guiding values:

• Healthier neighborhoods focused on quality of life

• Adaptable site design and flexible home configurations

• Deep green construction and inhabitation over a building’s life cycle

• Centering anti-displacement

• New possibilities for ownership, subsidized rentals, and more affordable housing

And while this design was developed specifically for Seattle’s typical lots and market, the values driving it are ones many Washington communities share. This is an invitation—and opportunity—for Washingtonians everywhere to imagine what could be possible in their own neighborhoods.

The “Seattle Six” is a three-story apartment building with six to ten households that fits on a range of typical residential lots. It has a compact form that is optimal for deep green building and observes the same height limits as Seattle’s Neighborhood Residential, Residential Small Lot, and Low-Rise 1 zones. In transit-rich areas, it can accommodate additional stories and units. With a floor area ratio (FAR) between 1.5 and 2.0, the Six is still small enough to bypass thresholds that trigger Seattle’s onerous Design Review. And finally, it proposes a clear direction for the urban design of streets and blocks that works in the short, medium, and long terms, aesthetically and economically.

HEALTHIER NEIGHBORHOODS FOCUSED ON QUALITY OF LIFE

The Seattle Six delivers a range of benefits for neighborhood vibrancy, connection, and attractiveness for residents both in and near Sixes. First, it energizes the sidewalk without overwhelming the street. By reducing the front setback to 12 feet but allowing stoops, covered porches, and balconies in an 8-foot-deep buffer, more residents have access to open space and a connection to life on the street. It replaces the idea of forced façade modulation with the option to embellish and individualize the building, while providing an amenity without complicating the basic structure. Overall, it is similar in height to currently allowed designs and recalls the classic small apartment buildings constructed in the decades before zoning strictures banned them from much of the city.

At the block level, over time, the Six establishes a land use pattern with well-defined urban edges and an interior courtyard in the backyards protected from noise, pollution, and street intrusions. It better preserves existing trees and makes room for new ones, a big advantage over typical oneplexes and townhomes, for instance, which slice up open space into narrow throughways or make backyards the only available land for new housing.

Speaking of backyards, the Six prioritizes access to larger rear yard open space, ample daylight, and options for big terraces for each flat. Units face both the street and the backyard, where kids can play or gardens can flourish, an improvement over another building across a narrow side yard. Residents cycling in will appreciate the design’s easy bike access, accommodating lockable individual bike storage at the ground floor and again in each unit.

What’s more, on an everyday quality-of-life basis for people living in or near a Seattle Six, the benefits multiply. Because denser housing types bring in new families, one block with ten Seattle Sixes would have enough families with kids under five to justify a small daycare. Five more similar blocks would have enough customers for a successful café. Ten more, and you have a walkable/rollable neighborhood with local jobs, rapid transit, retail, services, and restaurants. At corners, the ground floor units could be live/work, corner stores, daycares, or cafes. Because it fits well with detached house neighborhoods, the Seattle Six can locate away from busy arterial streets and near to places like parks, schools, and libraries, bringing more vitality to every block.

Bottom right: a full block of Seattle Sixes, showing how exchanging narrow side setbacks for larger back yards creates far more useable open space and more room for big trees.

In most cases, building a Seattle Six would require demolition of an older structure, just as a big new oneplex does today. This is exactly why Seattle should also allow alternative infill options like backyard ADUs and small-plexes that can coexist with older structures that remain in fine shape.

ADAPTABLE SITE DESIGN AND HOME CONFIGURATIONS

The Seattle Six supports a range of household sizes, multi-generational living, and moving within the building as life situations change. One can downsize and “age in place” or upsize as their family grows without having to give up the community of neighbors they’ve gotten to know.

Even on lots smaller than the 50’x100’ Seattle standard, the design is flexible enough to offer a variety of unit sizes. Floors can be a mix of family-sized one- and two-bedrooms; they can combine into one large multigenerational floor and later split into a principal flat and mother-in-law; or they can comprise a sprinkling of studios. A single central stair optimizes each floor for living space rather than the dark double-loaded corridors typical of larger apartment buildings. The version shown below is built on a concrete slab at grade level, but a partly below-grade floor of garden units would be practical depending on the topography.

The ground floor features accessible units via ramp, as well as a flexible studio. Residents can use it for a variety of purposes: for residents with temporary disabilities, housing a caretaker, or a short-term guest suite. Alternatively, it could be a common room, hosting things like teen game nights or get-togethers in a co-housing community.

DEEP GREEN CONSTRUCTION AND INHABITATION OVER A BUILDING’S LIFE CYCLE 

Buildings are a major source of climate emissions, but they don’t have to be. They can incorporate deep green construction that reduces a building’s embodied and operational carbon.

To this end, the Seattle Six is conceived using Passive House principles in its design. The Six’s simple, compact form, continuous insulation to keep interiors comfortable at a consistent temperature, and shared party walls reduce energy loss, paying back residents with a lifetime of low heating and cooling demand. Paired with rooftop photovoltaic panels, the Seattle Six can be net zero energy.

As for materials, the Six’s structure is designed with a dowel-laminated timber structure, which sequesters carbon and minimizes the need for concrete or steel, resulting in a low embodied carbon construction. The mass timber party walls and stair core satisfy the fire resistance rating. And bonus: it can be remanufactured for use in a future project as part of a more circular economy.

The Six also accounts for its region’s natural environment. Its green roof and on-site storm water management limits runoff from the site. And as wildfire smoke becomes more commonplace, the Six’s heating recovery ventilation system not only saves energy but filters pollutants to supply fresh air throughout the building.

COUNTERING DISPLACEMENT

The goal of Seattle’s Urban Village growth strategy was to concentrate new housing around commercial centers and serve them with an expanded transit network. But the strategy’s zoning changes disproportionately landed on poor or BIPOC neighborhoods, such as the Rainier Valley. The consequence has often been a cycle of speculation, displacement, and gentrification at the expense of people who’ve built their lives there.

Having a small apartment building that can plug in anywhere, starting in areas the city characterizes as having “low displacement risk” (i.e., most residents have the means to stay in their homes or find other housing nearby), would reduce the pressure on housing in other, less expensive areas. In a city like Seattle that’s adding lots of jobs, building lots of homes is essential—and the Six is a template for every neighborhood to do its part.

Allowing six or more households to divvy up the cost of Seattle’s pricey land lowers housing costs, too. Efficient, modern buildings like the Six would offer a mid-sized and mid-priced option between detached houses or townhouses on the one hand and large apartment buildings on the other. Indeed, Sightline recently analyzed possible development scenarios under Portland’s new zoning code. It found that new triplexes and fourplexes weren’t quite financially viable there in most cases, but that sixplexes in Seattle’s more expensive market might be.

In other words, the Seattle Six fights displacement in exactly the same way it fights segregation: it creates a new, cheaper way for people to live near jobs, parks, schools, and good public transit while reducing development pressure on other vulnerable neighborhoods.

NEW POSSIBILITIES FOR OWNERSHIP, SUBSIDIZED RENTALS, AND MORE AFFORDABLE HOUSING

We’ve underproduced housing for nearly a generation, putting even the most modest starter home beyond the reach of most Washingtonians. In just a decade, the state’s median home price has increased by 237%. Rents are on a similar trajectory, rising 183% for a two-bedroom apartment over the same period.

Whatever form new development takes, we’ll also need creative forms of ownership: co-ops, urban co-housing, and condos, for example. One interesting idea well suited for Seattle is the Polykatoikia, where landowners who are cash-poor but land-rich negotiate with a developer to swap a new apartment building on their land in exchange for a flat or flats in that new building. It is an excellent way for local landowners to maintain and grow generational wealth, stay in their neighborhoods, and create new homes in the process.

To the south, Portland’s Residential Infill Project allows developers to build extra units in exchange for affordable housing. The Seattle Six framework could easily support more households, too: either with an extra floor or a smaller height limit bonus to add a level of garden suites. Seattle’s Mandatory Housing Affordability performance option won’t help private developers create on-site affordable units given the small scale, but perhaps some of the MHA payments taken in by the Office of Housing could be deployed to finance small apartments, similar to how the Equitable Development Initiative has been supporting anti-displacement efforts.

BUILDING THE TOMORROW WE WANT, TODAY

It is a watershed moment for Washington: an opportunity in our housing policy to address climate change and racial inequities while building the homes we need and communities we want. The Seattle Six is just one model of how that might look. It’s also an invitation, as state leaders consider critical middle housing legislation, for communities across the state to boldly envision the future they want and build it into reality.

Seattle’s university cooperative school charrette

A fact of life: community-centered work takes a long time—often five or more years—to turn projects from dream into reality. A shared vision created and owned by the stakeholders is the solid foundation that sustains the project through the inevitable challenges and transitions of this long gestation. One of the main tools we use to help develop this vision is the Community Design Workshop, often called a “charrette.”

CAST architecture is working with University Cooperative School to expand its space in the historic Maxwell Building. Developing such a vision was the focus of our recent workshop with teachers and staff. The group’s excitement coalesced around the concept for a central space we are calling "The Hive," a versatile, warm, and inviting student commons where kids of all ages can cross paths for both structured and unstructured activities.

During the charrette, we used a series of guided design exercises to draw out feedback: a brainstorming discussion; a walkthrough of the unfinished space with the main room dimensions laid out on the floor with tape; a game where participants voted on the appeal of various inspiration images with colored stickers; and a facilitated sketching exercise to document the emerging consensus.

This may have been one of the easiest workshops we have facilitated. With some stakeholder groups, we need to work extra hard to ensure all voices are heard (not just the loudest ones). These elementary school teachers—long accustomed to consensus decision-making—were amazing to work with, ready to jump into each stage of the meeting with insightful comments and actionable suggestions.

Construction progress! This side-by-side construction shot and rendering look down the central circulation spine at the José Martí Child Development Center, which connects the entry, classrooms, and outdoor play area. This new center will provide high-quality Early Childhood Education for 74 children.

A unique aspect of our involvement is that we've been part of the larger team since the early feasibility stage of the project, long before there was a specific childcare provider.

We have played a crucial role in shaping the evolving design of the overall building to ensure the space would be viable as an ELC. From big-picture design elements like the location of the play yard and the relationship of the main entrance to the sidewalk and courtyard; to detailed technical aspects, such as maintaining at-grade egress from toddler classrooms, we’ve provided clear direction to the evolving pieces of the larger building. We ensured the five floors of apartments above wouldn't impinge on the necessary duct and exhaust shafts that allow us to include a much-needed full commercial kitchen in the center.

CAST is proud to be part of the team for the Cedar Crossing affordable housing project, in partnership with El Centro de la Raza, Bellwether Housing, and Mercy Housing NW. On-site child care is an important component of the project, which co-locates resident services in the same building with family-sized housing units.

A new hatchery & beach shelter for the Port Gamble S’Klallams

On the beach at Point Julia where their village once stood, the Port Gamble S’Klallam Tribe’s Hatchery and Beach Shelter combines pragmatic uses with symbolic content. Salmon fishing is central to both the Tribe’s traditional identity and its contemporary outlook. This project recognizes the cultural importance of both the place and the program, while providing solutions for these activities to flourish in the 21st century.

Components:

• Two-story salmon hatchery

• Open-air structure shared by Tribal fishermen and the community

• Landscape restoration along the beach between structures

• Reorganization of the hatchery’s water intake system in the adjacent ravine

Point Julia is a prominent spit that protects Port Gamble Bay. This project area falls within a designated archaeological site that is both a busy workplace for the Tribe’s commercial fisherman and a popular recreation area. It is also the burial ground of their ancestors. Within this sensitive zone, we have limited the building footprint to areas already disturbed by prior construction.

In traditional Salish building in the intertidal zone, permanent poles fashioned from tree trunks were sunk deep into the sand, then clad with removable cedar planks. In a modern analogue, exposed auger-cast concrete piles support a lighter skin of glass, polycarbonate, and wood.

While minimizing excavation, elevating the hatchery on piles allows the lower level to withstand up to three feet of storm-driven tidal flooding. Flooding is predicted to become increasingly common as the effects of global climate change are felt locally. The lower level houses a garage, maintenance shop, and egg-incubation room with equipment that is both durable and moveable. The upper floor contains offices, water-quality testing, and filtration equipment. The spectacular conference room on the southwest corner can be entered separately, accessible to the wider community.

The second story of the hatchery emerges above Point Julia Drive at eye level to the road. Within the lantern of the enclosed porch, we are working with S’Klallam artist Jimmy Price to create a site-specific installation to mark this arrival point.

If the new hatchery forms a gateway to the beach from the landward side, the beach shelter is the Tribe’s front door on the sea. It will provide a work area for fishermen who pull their boats onto the beach and will also anchor the arrival of the annual Canoe Journey, the region’s most important inter-Tribal celebration. The shelter’s high roof encloses both hardscape and a generous slice of beach. Its oversized beams and exposed rafters make an explicit nod to traditional wood construction. A low-roofed plumbing core that echoes the hatchery houses hygienic cleaning sinks and the beach’s first public restrooms.

On the beach between the two structures, we will restore the native landscape in a way that continues to welcome the community. Existing paths are strengthened and the future pedestrian connection with the Tribal Center is initiated. Our experience of a summer afternoon on the beach with Tribal elders drives the landscape palette; along with salt-tolerant erosion control plantings, the beds reintroduce traditional edible and medicinal plants.

seattle neighborhood residential

Green Zoning means going beyond detached houses and townhouses, to a more urban, green residential type. Let’s trade the sideyard for a backyard with more homes facing the street with a useable yard. The typical setbacks on narrow, deep lots force townhomes to be perpendicular to the street and facing useless sideyards.

• Reduce front yard setback and eliminate side setback

• Porches and balconies can extend in front

• Max. depth 50% of the lot, apartments with window on street and larger backyard

• A compact form is easy to build and energy efficient

• Space for 3-10 households per parcel

• Works for larger units - less floor area wasted on stairwells

• Backyard trees remain

If we want to crack the housing crisis, ADUs aren’t enough. We need a repeatable adaptable accessible single-stair, #Passivhaus 6/8/10plex that can be financed, permitted, constructed nearly everywhere on a margin that makes it more profitable than townhomes or detached homes.
