Over the past year we have been exploring the history of b9 architects' projects in Seattle, focusing on the strategies we employ in each project to provide meaningful open space, both private and communal. These strategies are often limited by the city's municipal code regarding parking, especially in projects on single urban infill lots compared to those that can be designed over several contiguous lots. Creating meaningful shared and private outdoor open space is an important aspect of b9 architects' design philosophy, reflecting our commitment to enhancing the quality of life for residents while contributing to the overall design of the urban fabric. In response to local codes, our approach varies based on the size and nature of the project, with a keen understanding of how the availability of space impacts design possibilities. 

In single lot projects, b9 architects faces limitations in open space strategies. Often provided in  private amenity spaces or raised courtyards at the project's center, shielded from public view, the spaces are smaller or individual. The challenge lies in optimizing the limited space while adhering to the code requirements, specifically around parking. The presence of alleys significantly improves the design possibilities for open spaces on infill urban lots. Courtyards become more feasible when alleys provide access to required on-site vehicle parking since the parking can remain at the edge of the site. When alleys are absent, open space is in direct competition with vehicle access, turnaround and parking. This circumstance often results in a woonerf strategy for the parking, an area shared by pedestrian and vehicle uses.

In single lot projects without an alley, parking directly impacts ground level open space. Greenwood 5 places a shared parking and pedestrian woonerf at the center of the site.

Urban Canyon placed vehicle parking at the edge of three infill lots to provide landscaped walkways and a courtyard at the center of the site.

As project sites expand to include abutting lots, b9 architects gains more flexibility in creating more thoughtful site planning and larger shared open spaces. The design team leverages the increased size to incorporate diverse strategies. In Urban Canyon for instance, a project consisting of three infill lots on a corner in Seattle’s Central Area,  there was ample space for both a large central courtyard and two shared pedestrian paths that connect to the abutting streets. The project created its own “alley” at the rear of the site to provide access to parking for each unit at the edge of the site. Row 1412, on the other hand divides the courtyard space into private yards for each unit that connects in a larger shared area between all the homes with parking accessed from the street below the units. Our largest project to date designed on 13 adjacent infill lots in Seattle’s Central Area, the un-built First Central Station, exemplifies the community-oriented approach. In the design phase we worked with representatives of multiple Seattle community groups to design a 10,000 square-foot courtyard that would be a privately owned and managed public space [POPS]. Adjacent to the POPS were small private patios that buffered family-sized units at the ground floor, and a large plaza for overflow of the proposed commercial uses. The project planned to provide below grade overflow parking for adjacent commercial uses and Washington Hall, a legacy community performing arts building, and an engaging space for the whole neighborhood that connected to multiple street frontages.

Row 1412 left an existing single-family home, and added a new duplex behind a 5-unit rowhouse. A series of private decks and landscaping provide a buffer between the three structures.

The privately owned public space [POPS] proposed at First Central Station would have provided a 10,000 sq ft. courtyard surrounded by ground floor commercial spaces and ground floor rental units with private patios.

In examining the courtyard strategies of two townhouse projects, Solhaus and Viewhaus, b9 architects was able to adapt to site constraints to create vibrant communal spaces. Solhaus, developed over two lots, features a large central courtyard, leveraging the ample space to foster community interaction. The courtyard is a focal point for the ten units, with several having garage-style roll-up glass doors that facilitate a seamless indoor-outdoor connection, enhancing the living experience. Conversely, Viewhaus, constrained to a single lot, employs a different approach to maintain an open communal space. One of its five units is elevated above ground level, optimizing airflow and light in the shared courtyard below. This strategy not only enhances the quality of the shared space but also demonstrates how thoughtful design can overcome spatial limitations. In both projects, strategic parking solutions are employed to maximize the available open space, reinforcing the importance of parking considerations in urban townhouse developments.

Solhaus used an underground parking solution to provide a large courtyard to encourage community interaction for ten units.

Viewhaus, limited to a single lot, raised a unit off the ground level to reduce the impact of the massing on the courtyard space. Fortunately an alley allowed parking to be placed in the rear of the site.

When space or budget constraints prevent the inclusion of large courtyards, front stoops offer an effective alternative for fostering social interaction and activating the site edges. This approach, common in East Coast streets where rowhouse design is well established, brings neighbors together at the front of their homes, creating opportunities for casual encounters and community building. Our projects Row 1412 and Galer Rowhouses exemplify this strategy, incorporating front stoops along with private outdoor spaces to encourage social interaction. These stoops serve as transitional zones between the public street and the private home, enhancing the streetscape while providing residents with a semi-public space to engage with their community. This approach demonstrates b9 architects' adaptability in using various design elements to achieve communal interaction in different urban contexts.

Due to site topography, and to capture outrageous views, the amenity space at the Galer Rowhouses was limited to roof top decks and front stoops that step down the steep hill.

In addition to the backyard patios pictured earlier, Row 1412 also provides front stoops to the rowhouse units to encourage interaction at the entry.

b9 architects frequently incorporates exterior walkways and stairways in their apartment designs to enhance shared courtyard spaces by encouraging spontaneous and planned interactions. Projects like Courtyard L, Ship Street, and Fremont Portal exemplify this strategy. At Ship Street, a “floating” volume of apartment units creates an exterior covered lobby, adding a dynamic architectural element while fostering a communal atmosphere. The Courtyard L project connects most units directly to the courtyard, providing a shared space for residents that also offers a buffer from the adjacent street. Fremont Portal uses a carved-out central courtyard to increase light and air circulation to all units and adjacent lots, benefiting an adjacent historic library and meeting city requirements for the project’s approved contract rezone. These projects highlight how exterior circulation can transform courtyards into vibrant, shared spaces that enhance the overall living experience.

Courtyard L uses exterior walkways and stairwells to place unit entries into this expansive central courtyard.

The Ship Street apartment floats one unit above the ground level to create an outdoor covered lobby. Exterior stairways and walkways provide passage to individual units.

In the current development climate, the feasibility of multiple lot projects is challenged. In order to lessen the impact of Seattle’s Design Review process, thus saving time, fee, and complexity, clients often opt to develop adjacent individual parcels under separate multiple permits rather than bundling them together under one design application. Additionally the Single Family, Accessory Dwelling Unit [ADU], Detached Accessory Dwelling Unit [DADU] cluster has emerged as a viable option in the Neighborhood Residential [NR] zone, where Design Review is not required altogether.

b9 architects' commitment to meaningful open spaces in Seattle's residential projects reflects a nuanced understanding of urban development challenges. While the triple lot projects that once allowed for expansive open spaces are less prevalent, the firm remains at the forefront of innovative design, exploring new strategies to maximize community value in the evolving development landscape. As Seattle continues to grow and change, b9 architects stands poised to contribute to the city's architectural legacy with their thoughtful approach to open space integration in residential projects.

Last year, Seattle updated the municipal code to encourage ADU and DADU developments on RSL zoned parcels. This would allow land owners to add two 1,000 sq. ft. or less residential units to their single-family homes.

This project under way at b9 architects retained an existing single-family house and placed two units to the rear. Three residential units were added next door on an adjacent lot.

As the first apartment project b9 architects was hired to do, The Portal in Fremont holds a special significance for the firm. From the outset, the client’s strategy included petitioning the City of Seattle for a site specific contract rezone, a process through which the City Planning Department, and finally the City Council could vote to change the parcel’s land use designation based on the development’s proposed design. In undergoing this process and extending the permit timeline, the project was able to gain floor area and height above the limit of its original zone requirements. Working through this process would also make this one of b9 architects’ most collaborative projects to date.

 From the beginning of the project, the team wanted to design a building that would feel rooted in the neighborhood. Through the Contract Rezone and Design Review process, b9 architects met with community members and organizations to hear their needs from the new project, and collaborate on the final design. Fremont, known for its eclecticism, is home to a number of famous public art spaces and events. Within walking distance of Portal, are the famous Fremont Troll, the Waiting for the Interurban statue and pergola, and the statue of Lenin. Annually the Fremont Solstice parade runs along 36th Avenue in Fremont featuring groups of nude, body painted cyclists. To match the community oriented spirit of the neighborhood, Portal was designed with a porous commercial space at street level. A restaurant space with roll up garage doors facing the street, and the building's interior courtyard allows customers and residents the ability to pour out into each space, blurring the boundaries between public and private space. This initial strategy carried through the entire Contract Rezone and collaborative processes with the community.

In general, a contract rezone through the City of Seattle would suit a larger development of aggregated parcels, covering perhaps a full block or more, and requiring design presentations to the neighborhood Design Review Board. If approved there, the strategy would be presented to the Seattle Hearing Examiner, who produces a report and recommendation to the Seattle City Council for approval. For Fremont Portal, the team committed early-on to undergo this process for this one 8,000 sq ft lot by itself. On a slope near North Lake Union, the site is adjacent to the historic landmark building of the Fremont Branch of the Seattle Public Library, and the historic George Washington Memorial Bridge (Aurora Bridge). To achieve this ambitious goal, the project team began several collaborative relationships; land use lawyer Josh Brower, joined the process early in the design review process to guide the team, while Principal Brad Khouri and architect Brian Johnson began a conversation with the Seattle Public Library and the Fremont Neighborhood Council to secure their support for the project.

The Seattle Department of Neighborhoods oversees all buildings with historic landmark status.  As part of the review, DON, wanting to ensure that the building proposal through the Contract Rezone did not obstruct  access to natural daylight, requested a shadow study to specifically examine how a building at an increased height would impact the three Reading Room windows on the landmark structure’s east facade. Fortunately, b9 had determined early in the project to create an internal courtyard that carved away building mass creating a void adjacent to the historic windows. After creating a shadow study in our BIM software, ArchiCAD, b9 architects chose to remove a unit from the top floor of the south west corner of the project to ensure the library kept its access to natural light. This move also created an opportunity for the project: to create a shared resident patio space on the fifth floor.

A second collaborator on the Portal, the Fremont Neighborhood Council was an important organization for the contract rezone process. Their support of the project would go a long way in securing approval from the Design Review Board, and other entitlement processes within the City of Seattle. The team reached out to the group early for their input and guidance on the project. In the conversation, the Fremont Neighborhood Council leadership pushed for more two bedroom units. In the initial Early Design Guidance meeting, the Design Review board asked for the proposed bulk and mass be reduced significantly along its north side, which resulted in the project losing sevenn of the eight proposed two bedroom units. After coordinating the reduction with the Design Review board with the ideal unit mix from the Fremont Neighborhood Council, the team found four more two bedroom units, while only reducing the total number of units by two, from 56 units to 54 units. For comparison, the code compliant version without the requested Contract Rezone would have resulted in 44 units. Per the Fremont Neighborhood Council’s recommendations the project went further in creating transparent spaces to combine the commercial and residential uses. Large windows to each commercial space flank the residential lobby creating a full line of sight through each space.

The Neighborhood Council also worked with the team to integrate public art installations with the project. The team reached out to 4Culture, a Seattle-based art advocacy group to orchestrate a search for public artists for the project, from Seattle and beyond. Local artist Caroline Davis represented b9 architects in the search that selected Verda Alexander, a renowned Los Angeles interior designer. Inspired by Fremont, Alexander iterated on her theme “Portal”, which would carry on as the project’s namesake, to create two pieces of public art. With a desire for the art to be intrinsic to the building, rather than additional, Alexander worked with our design team to detail the building's siding, engraving the art directly into the sourced brick cladding. A second art piece, originally proposed as a glass mural attached to the project, became vinyl applied directly to metal siding to best resemble actual building cladding.

Thanks to a highly collaborative design process facilitated by the Contract Rezone, the Fremont Portal is an elegant addition to the eclectic Seattle neighborhood. Replacing traditional hallways, exterior walkways provide abundant light and open air on at least two sides of project units. A courtyard, privately managed, but publicly accessible exists at street level, abutted by the restaurant space, currently leased by Just Burgers, and the landscaping of the Fremont Branch Library. Shared community areas, including the central courtyard at street level, the shared balcony on the fifth floor, and a large roof deck provide outdoor space. The theme of community collaboration continues through the resident experience as a miniature p-patch in galvanized steel planter boxes on the roof provides residents a space to grow their own plants and vegetables. Fremont Portal exemplifies for b9 architects  what can be accomplished in a truly collaborative process that benefits the neighborhood.
