Anson House was transacted earlier this week at $172 million, BT understands.
European fund manager SEB is acquiring the 13-storey office block from CBRE Global Investors, which had put up the property for sale earlier this year at an indicative pricing of $175-180 million.
The $172 million price translates to $2,252 per square foot on net lettable area of 76,362 sq ft for the building, which is on a site with about 82 years of remaining lease.
