Jeremy Titchen has left Climate Change Capital to join Qatari Diar’s London office as the sovereign wealth fund continues to push forward and broaden its UK expansion plans.

Titchen joined Qatari Diar’s London office this week as development director, where he will report to former Royal Bank of Scotland property head John Wallace.

Wallace was recruited to head the new office in May this year.

Qatari Diar, a wholly-owned subsidiary of the Qatar Investment Authority, now employs around 10 people at its Grosvenor Street office as it continues to move swiftly with its UK property plans.

Titchen has been appointed as development director and will be responsible for driving forward its development of the Chelsea Barracks site in Chelsea.

He was previously a director at investment bank Climate Change Capital and left, because of the fund's shift to standing investments from development.

Before that he worked with Wallace running Omega Land, a vehicle set up to manage a RBS development portfolio following a £300m management buyout by Wallace and backed by Morgan Stanley Real Estate Funds (MSREF).

He also briefly worked as Exemplar Properties which MSREF brought in to replace Omega in January last year.

However, Titchen is best known for his work as a commercial development director at the Duke of Westminster’s property company Grosvenor.

His main task at Qatari Diar will be to manage the redevelopment of the Chelsea Barracks site which the group bought in a joint venture with Christian Candy’s CPC Group in April last year for £959m.
