Good post ,this has the mark of the greenies, pushing peeps towards timber framed houses. I amazed though that people believed the redress scheme would be paid for from general taxation. The timing clearly isn't good due to the lack of housing at the moment but what is it likely to stick on to the cost of an average house? 1000/1500 euros.
The cost of building your average house at the moment is somewhere around €250k, the material supply cost of the concrete element of that including the blockwork as well is probably 10k max so you would be looking at an uplift of €1,000
Note - this is serious finger in the air territory now! I'd guess the foundations and slab cost approx €3000-4000 for the material cost, and €5000-6000 for the bricks, lintels etc. The 1st floor in spec build is always timber joists anyway, or Posi joists in most recent ones
