It’s not just the cost of an apartment. Keep in mind timeframes to any proposed changes in regulations on apartment design or standards.
I doubt any 100 unit apartment development has gotten planning permission in less than two years from appointing a design team. Say 4 months to do surveys, design, drawings. Planning 2 months, further information request 2 months (optimistic depending on what’s requested), 1 month to review submitted further information. 1 month for grant. Then appeal to the board. 18 months minimum for that. That’s 28 months.
Presuming it doesn’t go to judicial review (which often happens in large Dublin developments) then you’ve construction which will be another two years at best before an apartment is occupied. That’s 52 months. Whatever changes they introduce in apartment design won’t be felt for a long time.
Now here’s a bigger problem. These are draft regulations to change apartment designs. Government holidays start soon so it will be September or October before these regulations are introduced and signed into law. Add the 28 months for planning. That’s over 3 years into the current government. Contractors don’t like uncertainty so are likely to wait the 8-10 months until the next government term to see who gets into power and what rent freezes, caps, subsidies, etc are introduced which could greatly impact the financial viability of the project. Their other option is to sell them all off plans in one transaction to provide cost certainty but that doesn’t allow purchase by first time buyers on completion.
