There are not enough houses or apartments being built to deal with the demand for affordable housing.

But of the homes that are being built, are they in the right locations?

Are we making the same mistakes we made a decade ago in building housing estates in Dublin's commuter counties, which could be contributing to urban sprawl and a return to lengthy commutes?

We were joined by a panel of guests to discuss this issue:

• Orla Hegarty, architect and assistant professor in the School of Architecture, Planning and Environmental Policy at UCD

• Frank McDonald, author and former environment editor of The Irish Times

• Catherine Martin, Deputy Leader of the Green Party

• Suzanne Meade, research fellow at the Transport Research Institute at Edinburgh Napier Institute
