A new online mapping tool that enables people to highlight where there are empty buildings that could be used for social housing has been launched.

'Reusing Dublin' aims to harness local knowledge to identify suitable premises, in an effort to lessen the homeless crisis.

The free-to-download app was developed by Dublin-based social enterprise 'Space Engagers', in partnership with the homelessness charity, the Peter McVerry Trust.

Francis Doherty from the trust said it had been working on redeveloping empty and derelict buildings for many years as it enabled the creation of high quality homes faster and cheaper than new build construction.

"The Reusing Dublin project is something that we hope will encourage members of the public to share their knowledge of their community and city by logging empty buildings. 

"The more empty buildings we can identify and reuse, the more homes we can provide to people impacted by homelessness in Dublin", he said.

It has been launched at Twitter's Dublin-based EMEA headquarters by the co-founder of Twitter, Christopher Isaac 'Biz' Stone.

Information on empty buildings can be submitted and viewed at www.reusingdublin.ie
