An affiliate of British real estate investment management company Mayfair Capital Investment Management, acting on behalf of its clients, has sold the long leasehold interest of 6 Park Street in Cardiff, Wales.

The property at 6 Park Street extends to 50,983 square feet of Grade A office accommodation over six floors and is fully let to Media Wales, which is owned by Trinity Mirror, and Deloitte.

Mayfair Capital's unit, Jersey's Mayfair Capital Property Unit Trust, sold the property, built in 2008, to Ship Street Advisors and ADAPT Real Estate, which represented Jersey-based investment firm UKRO on the deal.

The firm sold the asset, situated adjacent to Central Square, in an off-market transaction, for 10 million pounds ($13 million).
