In April, T-Mobile and Sprint agreed to merge and create a new $146 billion T-Mobile. Its primary headquarters would be in T-Mobile’s hometown, Bellevue, Wash. T-Mobile’s campus in Bellevue is already about 900,000 square feet. In late September, T-Mobile scooped up 88,000 square feet at the Sunset Corporate Campus, a pair of five-story buildings just down the road from its Bellevue headquarters campus.

T-Mobile signed a 5 year lease for the 88K square feet at Sunset, which is believed to be used as temporary space to house employees while the mobile carrier expands and renovates it’s existing HQ just West. This leaves roughly 11,000 SF left in the entire Sunset Campus.

Major Headquarter renovations are set to take place in Bellevue’s Factoria neighborhood. T-Mobile will spend $160 million over the next three years to revamp the campus, the lease for which the company renewed through 2030 with landlord Ivanhoe Cambridge. The new campus will feature amenities like dry cleaning drop-offs, a bike repair station and an on-site pub. T-Mobile said it increased its headcount inside the campus by more than 56 percent in the past five years to more than 6,200 employees, excluding retail employees. The company employs 8,100 people in the Puget Sound region, also excluding retail employees.

Magenta in Sodo? Forbes reported that the Mariners have reached an agreement with T-Mobile — the company started under a different name by Mariners owner John Stanton in 1994 — for the naming rights of their stadium, which had been known as Safeco Field since its construction and opening in 1999. The name change will take place in time for the 2019 MLB season.
