Vulcan Real Estate has sold its planned mixed-use residential development site in downtown Bellevue. The property, located at 206–224 105th Avenue Northeast, was listed by CBRE in June 2025 under the project name Filament.
Vulcan originally acquired the site in 2021 for $25 million, according to public records. The company had planned a two-building mixed-use apartment project known as Filament East and Filament West, totaling 302 residential units with ground-floor retail.
Filament West, also referred to as Plaza 200, was designed as an 8-story residential building. Approved plans included 151 apartment units, 4,332 square feet of retail and service space, and 2.5 levels of below-grade parking with 162 stalls. The design featured a southwest residential entry, a covered entry for the leasing office, and an outdoor seating area with landscaping and public art.
The site previously housed a one-story building used most recently by Bosa Development for its One88 showroom. It was demolished prior to the development’s approval. Although the project had received permits and was ready for construction, work had not started when Vulcan listed the property for sale.
According to public records, Holland Partner Group purchased the site for $36 million. The property sits near several Amazon-leased office towers in the downtown core.
Holland Partner Group says it plans to move forward with the entitled project, which includes two residential towers. In a statement to the Puget Sound Business Journal, an HPG managing director said construction is anticipated to begin in the second half of 2026.
He noted appreciation for Vulcan’s stewardship of the property and expressed confidence in the existing design created by Encore Architects.
