Discovery West is the fourth DevCo project in the Issaquah Highlands. The project sits on a four-acre parcel and is a residential multi-family project. There are 209 units, mostly flats, but the project also includes eight carriage housing units. The largest building incorporates an underground parking garage. The second largest building includes project amenities, such as leasing, café, lounge, fitness area, indoor pool and kids play zone. The site has surface parking, rain gardens, a large open lawn with bocce court, community gardens, outdoor plazas and a pet off-leash area. It also includes a bike barn, with a tool station, to accommodate residents' bikes; and associated streetscapes and connections to trails.

GGLO designed the site's six buildings, landscapes and interiors, incorporating these guidelines in the design:

  • Housing gathered around a shared space
  • Underground parking, and surface parking placed internally, removed from street view
  • Creating a unique identity for the project
  • Bulk and height of buildings compatible with surrounding and future uses
  • Using simple materials in a beautiful way to match a rustic luxe concept
  • Design social gathering places, indoor and outdoor
  • Easy access to shopping and other services
  • Recycling and yard waste facilities
  • Bike barn provides a secure location for residents
  • Surface parking is graded, so water flows to rain gardens which clean water before it goes to detention. Rain gardens also provide education value
  • Project is connected to pedestrian and bike trails as well as bridge

The project contributes to the overall sustainability of the Issaquah Highlands by providing housing within walking distance of nearby businesses. Residents have access to amenities such as a grocer, restaurants, services and to transit - this greatly reduces the number of single-driver trips. The inviting sidewalks and trail network throughout the Highlands encourages residents to leave their car at home and walk to the neighborhood pedestrian-friendly town center.

O'Brien & Company provided technical assistance and performed third-party verification for the project's Built Green certification.

The following are some of the project's environmental attributes, which contributed to certification:
