17-unit Capitol Hill apartment built to maximize small infill lot

Capitol Core was built on a 2,700-square-foot site.

A six-story, 17-unit apartment building called Capitol Core has opened on a small site in the Capitol Hill neighborhood of Seattle.  

Designed by NK Architects and built by Cascade Built, Capitol Core was built on a 2,700-square-foot site.  The architect said the building maximizes its small infill lot with a unique linear design. 

The project is certified Built Green 4-Star. It was constructed using high-performance building practices and durable materials drawn from the Passive House standard of building: toxin- and allergen-free interior finishes, added insulation, extra-large windows, and energy-efficient mechanical systems. NK said this offers occupants continuous fresh indoor air and a healthier, more comfortable environment with fewer drafts.

All the apartments are corner units. The 15 studios are 306 to 394 square feet and the two penthouse loft apartments are 508 and 587 square feet and have private rooftop decks.

Jim Snelling and his wife own the project, which they developed as JaMar Investments. Rents are $1,300 to $2,200 per month, and average $1,470.

Capitol Core sleeping areas are accessed by spiral staircases.

Pax Futura will bring 35 super-green apartments to site in Columbia City

Cascade Built broke ground last month on Pax Futura, a 35-unit apartment building in Columbia City that is targeting Passive House certification.

The developer said it received a $55,788 Edwards Mother Earth Foundation Grant to support its ultra-high-performance goals for constructing the four-story building at 3700 S. Hudson St.

When the project is completed in fall 2018, Pax Futura will have 32 studio and one-bedroom units, along with three live/work units. There will be a courtyard and 1,050 square feet of retail space, but no parking.

NK Architects designed the project and specializes in urban housing and Passive House design.  

The units are expected to use 90 percent less energy for heating and cooling than average building stock.

How ‘negawatts’ help the building industry fight climate change

In this recent article, Zack Semke of NK Architects explores the idea of viewing our buildings as clean energy power plants. 

Buildings are the biggest single contributor to greenhouse gas emissions in the U.S. Curbing emissions will require constructing more efficient buildings and relying on renewable energy. 

Very green building in very cold place: ZGF wins Petal for project in Colorado
