New RIBA president Sunand Prasad will be hosting a debate on 'Dismantling Barriers to Black Participation in Urban Design', which will be chaired by Stephen Lawrence Charitable Trust chair Sarah Ebanja.
'Thanks to the Stephen Lawrence Charitable Trust we now have an annual event at which these issues can be raised, debated and discussed and at which our progress can be measured.'
Stephen's mother Doreen Lawrence will also speak at the event.
The RIBA award is for young practices working on projects with budgets of under £1 million.
The shortlist is: Tonkin Liu's Singing Ringing Tree in Lancashire; Wooda, in Crackington Haven, Cornwall, by David Sheppard Architects; Focus House in north London by Bere Architects; Kander House also in north London, by Jamie Fobert; and a private house in Richmond, Surrey, by David Mikhail Architects.
The award will be judged by former RIBA president Marco Goldschmied and will be presented at the Stirling Prize dinner on 6 October.
