Cost of building an extra floor

Hi there,

I'm new to the group, so apologies if it's on here somewhere.

We're just buying the house, so this is going to be a while in the future...but: Does anyone know the rough cost for building an extra floor on a house in Malta? Like, are the builders as overpriced as most of the buildings here? 🙂

It's 8m X 12m I think , according to the plans. So not huge, but it'd be nice in the future to build up a level, so we have a few more bedrooms. Then I can make my rooftop paradise!  🤔

there's really no ball park figure, and getting planning permission if you dont have it already can be years if at all
