CoStar Group, the leading provider of online real estate marketplaces, information, analytics and news in global property markets, has signed for a United Kingdom head office, taking 51,721 square feet in London.
The Nasdaq-listed group is expanding from the 42,254 square feet it leases at The Shard in London Bridge and the nearby Blue Fin Building in Southwark to take all of the fifth floor and part of the sixth floor at the Blue Fin.
CoStar has taken a 10-year lease and plans to relocate staff in August 2025. It has decided on the building to meet its objectives of consolidating its London offices into one building, improving the workplace environment, facilities and technology, and providing space for continued expansion.
It occupies just over 23,000 square feet across Level 26 and Level 13 at the Qatar Investment Authority's Shard on leases expiring in August 2025, and around 20,000 square feet in the Blue Fin.
CoStar's United Kingdom businesses include: CoStar UK, the commercial real estate information provider; STR, the hospitality benchmarking data group; LoopNet, the commercial real estate online marketplace; and residential property portal OnTheMarket.
Oxford Properties is the landlord at the 473,776-square-foot Blue Fin Building at 110 Southwark Street. The building is close to Blackfriars Station as well as the Tate Modern and Shakespeare's Globe theatre on South Bank.
Cushman & Wakefield advised CoStar.
The agreement comes at a time of significant expansion globally for CoStar Group, with revenue growing from $252 million in 2011 to $2.46 billion in 2023 and employees growing from 1,000 in 2011 to over 6,400 today.
