Green Hammer Design Build - Ankeny Row Zero Energy CoHousing

An urban community of five two-story townhouses, one loft and one common studio surrounding a courtyard, this pocket neighbourhood is designed to encourage community interaction. The siting of homes maximizes light, energy and construction efficiency while balancing privacy and orientation to the community. Floor plans accommodate aging in place. Ankeny Row is constructed to the Passive House standard and is Net Zero Energy Ready. 2YokeDesign provided interior design.

Ankeny Row combines the best of the old and the new, reflecting the owners' values while respecting the legacy of the Buckman neighbourhood. It's a shining example of sustainable urbanism. The project's location in an existing urban neighbourhood on a designated bicycle route and in close proximity to public transportation allows the owners to live a car-free lifestyle if they choose. The owners wanted the community to feel welcome and connected to the co-housing project. Therefore, the townhouses are accessed through a pronounced pedestrian entrance, defining the Ankeny streetscape, further enhancing neighbourhood walkability, and keeping “eyes on the street”.

The building forms and site organization — townhouses arrayed around a central courtyard — are reflective of many examples of historic courtyard housing in the four quadrants of Portland. The common courtyard is designed in relation to the townhouses to afford ample private, semi-private, and public outdoor rooms offering a full gradient of social experience. Balconies, for example, allow residents to take advantage of the sun in privacy or simply engage in people watching. The co-housing model furthers economic efficiency and expanded, shared amenities while improving social cohesion and connection. A common room and kitchen allow group and community activities and hosted dinners. A courtyard garden supports urban agriculture and provides an opportunity for residents to connect with the ecosystem in an urban setting. Convenient bike parking for the owners and their guests encourage cycling over driving to the site.

The townhouses are contemporary and yet pay homage to the great craftsman tradition of the Buckman neighbourhood. Many of the homeowners worked with 2Yoke Design on their interior design. The open floor plans encourage informal gatherings centred around the dining and kitchen areas. First-story master suites allow the owners to live entirely on the first floor if desired or needed.

Quietly sheltering this architectural experience is a super-insulated, airtight Passive House envelope, reducing heating energy demand by approximately 90% over conventional construction. Interiors are light filled and supplied with superior indoor air quality through constant supply of fresh filtered air, thermal comfort, and acoustic isolation from urban noise. In this way, livability is improved while the carbon footprint is nearly eliminated. A small rooftop solar photovoltaic panel is expected to produce enough electricity to allow Ankeny Row to achieve Net Zero certification through either Earth Advantages Net Zero or the Living Building Challenge’s Net Zero Energy Building (NZEB) certification.
