Huge numbers of new houses are being built in areas with no infrastructure such as schools, water, transport and drainage.
A housing expert said many of these housing units are going into small towns on the periphery of Dublin, forcing homeowners into long commutes.
Architect and UCD academic Orla Hegarty said people who object to the building of housing estates in small, underdeveloped towns should not be dismissed as Nimby (not in my back yard) objectors.
"People in these towns who raise legitimate concerns about this are not Nimbys. These are real issues for existing communities, impacting on quality of life, access to services, congestion etc. This is why 'planning' is so important," she wrote.
Prof Hegarty was reacting to figures this week from the Central Statistics Office showing that 21,000 housing units were completed last year. Many of these were in housing estates.
The UCD lecturer said 30pc of the estate housing built last year is in just seven Dublin commuter towns.
These include an additional 829 units in Naas, Co Kildare; 429 units in Dunsaughlin, Co Meath; 659 in Celbridge, Co Kildare; some 494 units in Navan, Co Meath; an extra 539 in Drogheda, Co Louth; a total of 451 in Wicklow town, and 465 in Greystones, Co Wicklow.
"So 3,866 new homes, over 10,000 people, are going into areas without adequate infrastructure, schools, water, drainage, transport."
Assistant Professor Hegarty said this pattern is repeated further into the midlands and around other regional cities.
She said the homes being completed are affordable to the buyers, at the cost of heavy State investment in new infrastructure, schools, services, public transport.
That is not being factored into simplistic housing policy that chases supply at any cost, she wrote.
This meant the housing being provided was not, in reality affordable to the Exchequer.
