T-Mobile has scooped up more office space in its hometown of Bellevue, Wash., according to a new report, as it prepares to bring Sprint into the fold, creating a much larger wireless competitor for AT&T and Verizon.

Real estate brokerage Broderick Group reports that T-Mobile has leased 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’s campus in Bellevue is approximately 900,000 square feet, the company has said in regulatory filings.

We’ve contacted T-Mobile for comment and will update this story if we hear back.

In addition to the new lease, the report says T-Mobile renewed nearly 175,000 square feet of office space at the Canyon Pointe complex in the city of Bothell, north of Bellevue.

T-Mobile is reportedly gearing up for a major renovation of its Bellevue campus.

In April, T-Mobile and Sprint agreed to merge and create a new $146 billion T-Mobile. T-Mobile CEO John Legere would remain chief executive of the combined company. Its primary headquarters would be in T-Mobile’s hometown, Bellevue, Wash.

Last month the Federal Communications Commission asked for more time to review the proposed merger, pausing an “informal” 180-day shot clock to rule on the merger.
