Architect Dermot Bannon has reiterated his call for regulations on one-bed homes to be changed, saying the lack of smaller units is stopping inward investment from companies such as Google and Facebook.
Mr Bannon was speaking at a forum hosted by the Simon Communities which discussed the housing and homelessness crisis. "We need smaller units. It's stopping investment inward from companies like Google and Facebook because there are no homes for young people who want to come over to Ireland for a couple of years or students.
"There's a whole section of society that require a smaller housing situation."
Michelle Norris, a senior lecturer in social policy at UCD, told the forum that "tough conversations" must be had with the CEOs of housing associations and the local authorities about why they are not availing of funding to tackle the housing crisis.
However, Aidan Culhane of consultants WK Nowlan Property warned that social housing was "very positive in the abstract and extremely unpopular in the particular". He said introducing it in local communities can be difficult.
