Rendering by Holst Architecture [enlarge]More midrise projects are likely on the block, which is a few steps east of Broadway.

Friday marks the first administrative design review for an ultra energy-efficient “passive house” apartment project planned at 311 11th Ave. E. on Capitol Hill. Prospective buyer Coho Collaborative intends to replace a trio of old houses on a midblock property about a five-minute walk south to Capitol Hill Station.

Holst Architecture, of Portland, is designing the eight-story, 72-unit project. It would total about 27,914 square feet. No parking is planned, but there would be 83 bike stalls — both in-unit and in the basement.

Apartments would be mostly SEDUs (small efficiency dwelling units), with 300 square feet or less. A few may have larger layouts. A roof deck is also indicated.

Coho Collaborative is described as the sister company to Cascade Built, which will be the general contractor. Both are led by Sloan Ritchie. The team also includes Place, landscape architect; KPFF, structural engineer; Chadwick & Winters, surveyor; RDH, sustainability consultant; and Staengl Engineering, MEP.

The developer intends to use the city’s Priority Green Expedited program, to expedite permitting via various green features including low VOC materials. The building itself would have a super tight envelope to minimize heating and cooling costs.

No broker is associated with the three-parcel, 9,800-square-foot potential assemblage.

Holst would be new to our market. Cascade Built recently completed the 29-unit Sienna, in the south Cherry Hill neighborhood. It also included many energy saving features. Cascade Built also served as general contractor for Solis, another passive house project, which is being offered by Colliers.
