Stacking prefabricated apartment units on top of existing buildings has been suggested as one solution to Dublin's homelessness crisis.
The Royal Institute of the Architects of Ireland is holding its annual conference at the RDS today.
Keynote speaker Michael Maltzan has previously worked on a similar design to tackle homelessness in Los Angelas.
President of the RIAI David Brown explains how it worked:
"They took a site with an existing one-storey building with it and very interestingly kept the one-storey building because they wanted to keep the fabric of the neighbourhood."
"They then built on top of that and made a platform and then built approximately 100 new fabricated apartments that were lifted into place in about three weeks."
