Snowflake is making a bigger bet on Bellevue, filing plans with the city to build out three more floors in Block 6 at the Spring District. If the permits get the green light, the cloud data company would significantly grow its Eastside hub and tighten its grip on one of Bellevue's fastest‑evolving neighborhoods.
What Snowflake Filed
According to a report in the Puget Sound Business Journal, Snowflake submitted its latest plans on June 24, asking the city to allow a build‑out of three additional floors in the Block 6 office tower it is subleasing from Meta. The filing is described as a tenant build‑out request that would follow earlier interior work already completed in the building.
Permits And The Address
City permit records list Block 6 at 1646 123rd Ave NE and show Snowflake has already pulled tenant‑improvement permits to convert several lower floors into office space, including a commercial kitchen on the third floor. Those details appear in Bellevue's public permit database; see the city's permit record for the Snowflake kitchen build‑out.
How Snowflake Got Here
Snowflake first announced in 2024 that it would move into the Spring District, positioning the project as a key home base for its Seattle‑area engineering team. Local coverage later documented the company opening part of Block 6 to employees in 2025 as it ramped up those operations. That rollout was covered by GeekWire, along with a separate account of the office opening in Downtown Bellevue Network.
Block 6 And The Neighborhood
The Spring District's developer describes Block 6 as an 11‑story office building with roughly 329,000 square feet of space at the northern edge of the mixed‑use campus. While the developer materials focus on the building's delivery, public filings and local reporting show that portions of the tower have been offered for sublease and picked up by Snowflake. See the Block 6 listing on The Spring District and coverage of Meta finally firing up its long‑dormant Spring District tower for background on how the space came into play.
Why This Matters For Bellevue
The Spring District sits next to the Spring District/120th light‑rail station and was planned as a transit‑oriented neighborhood, so additional finished office floors could translate into more daytime workers and stronger demand for nearby retail. City planning documents for the Spring District and regional assessments of Eastside office projects point to active tenancy in these newer towers as one signal of renewed appetite for Class‑A office space; see the City of Bellevue planning materials for broader context.
