Andrew Martin is to join CB Richard Ellis’s investment committee after he retires as Hermes’ retail group director next month.

In his new non-executive role – which he takes over from James Hysop, who is retiring – Martin will oversee 20 discretionary mandates with assets worth £3.2bn. He will also advise CBRE on trends in institutional demand for real estate.

As head of Hermes’ retail group, Martin managed £4.7bn of retail property. However, this retail expertise was “coincidental” with his appointment, according to CBRE Investors managing director Mike Marshall.

“He’s done everything over the years. As a non-executive member, he’ll be reviewing a balanced portfolio,” Marshall said.

“We have a high transaction turnover and more portfolios than some investment managers. Andrew has an instinct for approving property purchases. Like anyone else, we want the right mix of talents on our investment committee. We had strategic strength and we need practical input.”
