Low room height; build higher than approved?

We have now decided on recessed ceiling spotlights (for a modest surcharge of €3000) and to keep the 2.43m ceiling height.

I would have gotten 60 Halox boxes in the concrete ceiling including electrical wiring from the GU.... what are they taking from you? GD

Your GU is cheeky.... Anyway - if I were you, I would still take all the necessary doses - I personally took too few back then...
