New Floor

You talk about 'battens': is this a floor surface which is over a concrete slab? If it is, and you are using solid softwood floor boards (probably tongued and grooved), then it looks like a reasonable price given that the boards cost around €30 per sqm. (This is a lot more than in the UK because it isn't a common solution to flooring in Italy.) Add the battens, fixing, and varnishing and it isn't difficult to reach €100. For the same sort of price it might interest you to look at some of the 'system' wood look floors (where you have a veneer of pre finished wood glued to a plywood substrate, in a format of 120cm x 2m or thereabouts) - you have a much wider aesthetic choice, greater avoidance of shrinkage problems, and a guaranteed resistant finish, factory applied. The material costs more, but the labour is significantly less. Check out places like Leroy Merlin for an idea of what is on offer if you think about this route. If it is on the ground floor you should ask yourself why the previous floor needed repairing, and now replacing - perhaps there is some damp involved which it would be wise to fix first.
