Greystar and GMC Projects Breaks Ground on 289-Unit Birchway Angle Lake Apartment Community in Seattle Submarket of SeaTac

SEATTLE, WA – Greystar, a global leader in the investment, development, and management of real estate, including rental housing, logistics, and life sciences, in partnership with GMC Projects, a Canadian-based real estate developer, announced the groundbreaking Birchway Angle Lake, a new apartment community at 19825 International Boulevard in SeaTac, WA, which Greystar will be the lead developer and builder. The project represents the second transaction capitalized in a strategic venture with Whitman Peterson.
Birchway by Greystar invites residents to enjoy comfort in suburban garden-style communities, providing practicality, tranquility, and convenience. Rooted in community, the Birchway brand offers the conveniences of the city without city prices.
“We are extremely proud to bring Birchway Angle Lake to Washington state and SeaTac,” said Aaron Keeler, Managing Director of Development at Greystar. “Focusing on providing new apartments at attainable rent levels, we worked with Whitman Peterson to secure equity financing. We’d also like to thank GMC Projects for their partnership and help in finding a creative deal structure that worked for all partners.”
Birchway Angle Lake will offer 289 apartments in studio, one- and two-bedroom layouts. It will also feature top-notch amenities like a large rooftop deck with views of Puget Sound and Mt. Rainier, a well-equipped gym, coworking areas, creative space, private work pods and a TV lounge.
The community is close to hundreds of thousands of jobs at the expanding SeaTac airport and thriving industrial hubs. The site is conveniently located across the street from the Angle Lake light rail station, connecting the community to cultural, employment, shopping and higher education options in Seattle, Bellevue, and Tacoma. The community also offers easy accessibility to all parts of the region with nearby access to I-5, I-99 and I-90.
Birchway Angle Lake design team included Weinstein A+U Architects, CT Engineers for structural engineering, Karen Kiest for landscape architecture and Lair Design for interior design. GMC Projects acquired the site in 2019 and secured the entitlements. Greystar is the project’s vertical venture developer, general contractor and property manager.
Pre-leasing for Birchway Angle Lake is expected to begin in early 2026, with the community scheduled for completion in mid-2026.
