Google Doubles Down on the Office, Buying London Site for $1 Billion

LONDON—Google plans to spend $1 billion buying office space it already uses in central London, saying it believes office work will remain vital for the tech giant.

The purchase of the site, called Central Saint Giles, near the British Museum, comes as the Alphabet Inc. unit is building a separate, massive new U.K. headquarters about a mile and a half away, next to London’s King’s Cross train station.
