Cost of supply and fit of two velux windows to a side room (previously garage)

Hi all

I live in a semi-detached house in Dublin 12, and I have a converted garage that’s currently in use as a living space. I’m interested in adding two Velux windows to the side-facing room of the garage conversion to improve natural light and ventilation.

I’d appreciate guidance and support on a few points:

1. Planning Permission
   • As the windows will be on the side elevation, I understand planning permission may be required.
   • If so, do I need to get architectural drawings done?
   • Is this something that’s difficult to handle myself, or is professional help essential?
   • Any idea on typical costs for submitting a basic planning application?
2. Velux Window Installation Costs
   • What would be a ballpark estimate for the supply and fit of two Velux windows (standard size, nothing custom or oversized)?
   • Any recommendations for reliable contractors or things to watch out for?

Thanks in advance

Pat
