Developer Argent last night appointed David Partridge joint chief executive with existing head Roger Madelin

The announcement was made at an event to celebrate Argent’s 25th birthday, which was held at King’s Cross, the site of the company’s 8m sq ft (743,200 sq m) redevelopment project.

Partridge – previously deputy chief executive – currently spends a lot of time in Manchester, where Argent is developing Piccadilly Place, a 675,000 sq ft (62,700 sq m) mixed-use scheme.

Madelin told Property Week that the appointment was a recognition of the way the company is run and was ‘long overdue’. The internal structure of Argent will not be changing.

‘We’ve been working so closely together for the last 17 years. As we are going to be expanding Argent to deliver King’s Cross and carry on in Manchester and Birmingham we are going to need more strength at the top,’ said Madelin.

The company is working on plans for several other projects in the north west, such as the potential redevelopment of the Fire station site at Piccadilly. It famously developed Birmingham’s Brindleyplace.

Partridge said it was useful for Argent to be able to have ‘chief executives in two places at the same time’.

Standing next to Madelin and Partridge last night as the announcement was made were Peter and Michael Freeman, previous joint chief executives of Argent, who stepped down in 1998 but remain non-executive directors and co-investors.
