Building Details

Cosmopolitan is a 34-story condominium tower at 819 Virginia Street in Seattle’s Denny Triangle, completed in 2007 by Mortenson Construction. At 34 floors, it delivers unobstructed views of Puget Sound, Elliott Bay, the Olympic Mountains, and the Downtown skyline from upper floors — among the most expansive view profiles available in the Denny Triangle submarket.

The building’s Virginia Street address sits at Denny Triangle’s northern edge, within a 10-minute walk of both Amazon’s South Lake Union headquarters and Pike Place Market. This cross-neighborhood position makes Cosmopolitan unusually well-located for buyers whose employment or lifestyle spans the SLU tech corridor and the Downtown retail and cultural core.

With approximately 253 units across 34 floors, Cosmopolitan has substantially more comparable sales history than most Seattle condo buildings — a meaningful advantage for buyers and sellers trying to price accurately. At Denny Triangle’s other confirmed building, Carbon 56 (56 units, 2015 Terry Ave, 2004), the scale is dramatically smaller. The two buildings serve very different buyer profiles despite sharing a neighborhood.

Cosmopolitan’s 34 stories deliver some of the most expansive views in Denny Triangle — Puget Sound and the Olympics to the west, Downtown skyline to the south. Upper southwest-facing units command meaningful premiums over comparable lower or interior-facing units. Jeff Reynolds can identify which units in current inventory have the strongest view exposure.

Virginia Street places residents within a 10-minute walk of both Amazon’s Denny Triangle campus and the Downtown employment core. Buyers who work across both areas — or who want flexibility — find Cosmopolitan’s mid-corridor location an advantage that pure SLU or pure Downtown addresses cannot match.

Frequently Asked Questions

Where is Cosmopolitan located in Seattle?

Cosmopolitan is at 819 Virginia Street in Seattle’s Denny Triangle — north of Downtown, south of Amazon’s SLU campus, and west of Capitol Hill. The building is within walking distance of Pike Place Market, the Convention Center, and Amazon’s headquarters. Jeff Reynolds can arrange private tours of available units.

Is Cosmopolitan in Downtown Seattle or Denny Triangle?

Cosmopolitan is in the Denny Triangle neighborhood, confirmed by the SCA Master Building Registry. Denny Triangle is a distinct submarket between Downtown, South Lake Union, and Belltown. The neighborhood is sometimes referred to informally as part of”Downtown” given its proximity — but it has its own character, pricing tier, and buyer profile. Jeff Reynolds covers both Denny Triangle and Downtown in his Seattle condo practice.

How many units does Cosmopolitan have?

Cosmopolitan has approximately 253 condominium units across 34 stories, completed in 2007 by Mortenson Construction. Unit count is multi-source confirmed at 251–253. KC Assessor Tier 1 verification is in progress to confirm the final figure.

How does Cosmopolitan compare to Carbon 56?

Cosmopolitan (~253 units, 34 floors, 2007) and Carbon 56 (56 units, 2015 Terry Ave, 2004) are Denny Triangle’s two registry-confirmed condominium buildings. Cosmopolitan is the high-rise, larger-HOA option with deeper resale history. Carbon 56 is a smaller former rental conversion with a tighter ownership community and lower HOA complexity. Jeff Reynolds represents buyers at both buildings and can walk you through the differences in detail.
