The institute is looking to overhaul three terraces – on the first, fourth and sixth floor – to the rear of its Grade II*-listed 1930s home.
It is not the first time the RIBA has run competitions to titivate its Portland Place HQ. Back in 2005, Azman Architects landed the project to design a new café bar in the reception of the building, which was designed by George Grey Wornum.
Entrants to the new contest will be asked to create ‘simple sustainable architectural garden terraces that will complement and enhance 66 Portland Place’.
According to a RIBA spokesman, the project will offer ‘a unique and prestigious opportunity to make a significant and lasting contribution to a high-profile, historic, precious, listed building at the very heart of current British design.’
A maximum of four designers will be shortlisted and interviewed on their approach to the commission.
A preliminary briefing paper outlining the project background and selection process can be downloaded from www.architecture.com/competitions or phone the RIBA Competitions Office on 0113 234 1335.
The deadline for completed expressions of interest is 5.00pm on Thursday 4 December 2008
