According to The Financial Times, the Poonawalla family has agreed a deal for the 25,000 square foot Mayfair mansion near Hyde Park named Aberconway House in what is expected to be the most expensive house sale of the year for the UK capital.
The five-storey property, dating back to the 1920s and Grade II listed, will be acquired by SII’s UK subsidiary Serum Life Sciences, people familiar with the transaction told the newspaper. The sale is said to have been agreed by Dominika Kulczyk, daughter of the late businessman Jan Kulczyk, who was Poland’s richest man.
According to sources quoted by the newspaper, while the Poonawalla family did not intend to relocate, the mansion would “serve as a base for the company and family when they are in the UK”.
It follows multi-million-pound UK investments by the family in vaccine research and manufacturing facilities near Oxford. Back in 2021, Natasha Poonawalla, the wife of Adar Poonawalla and Chair of Serum Life Sciences, had announced plans for a new Poonawalla Vaccines Research Building backed by 50 million funding commitment as part of a partnership with the University of Oxford.
