11 families have received keys to their new homes in Dublin as part of a new affordable housing scheme run by the housing body Ó Cualann.
It is providing three-bedroom semi-detached houses for around €180,000.
The housing group was founded in 2014 by people who have worked in not-for-profit groups in countries like Haiti and South Africa and who also had a background in construction.
Spokesperson John Moore said the vision is to build sustainable communities with mixed income and ethnicities.
There are already 17 families living in the Baile na Loachra development in Ballymun, 11 received their keys today, with a further 21 due to move in before the end of the year.
Ó Cualann is self-financing and borrows the money to build the houses on public land, paying Dublin City Council a nominal €1,000 per house.
The affordable houses are then sold to the families on a cost basis.
The families must earn under €79,000 for double income and €59,000 for single income.
There is a clawback if the houses are sold within ten years.
This has been increased to 20 years for future developments at the request of local authorities.
The Dublin residents have already held meetings and have drawn up a charter which requires everyone in the community to abide by a number of rules, such as keeping paths and verges tidy and to be of "good character".
The charter also says that "anti-social behaviour will not be tolerated".
There are a further 39 houses planned for another site in Ballymun and 20 in Waterford with plans also for housing in Limerick.
