Four architects have been shortlisted to design a masterplan for London's South Bank Centre arts complex.

The four chosen from the initial list of 13 are Jeremy Dixon.Edward Jones, Michael Hopkins and Partners, Rick Mather and Associates and Rem Koolhaas's Office for Metropolitan Architecture.

Frank Duffy, chairman of DEGW who drafted the masterplanning brief, said Dixon and Jones were chosen for their "intellectual rigour" and Royal Opera House experience, Michael Hopkins for his "determination pragmatism and drive", Rem Koolhaas for his "understanding of the modern cityscape" and Rick Mather for his experience of sensitive university sites and arts projects.

The four will be invited to a further briefing on the South Bank Centre site followed by a final interview. A winner will be chosen in the first week of May.
