Building a recording studio

[pianoman53]

Hey all,

So I have the opportunity to get my own working studio within another building. Two of the walls are facing a small-ish street, one wall is facing the hallway, and one door is facing a dance studio. It's quite clear that I'll need isolation, as the dance studio is occupied between 16-22 Monday-Thursday. (I'm sharing this with another person, so to only be able to practice until 16 is not enough).

Good thing is, the dance instructor is going to take care of the construction, and will begin with tearing down all the walls, to the build optimize the space. That means, my friend and I can tell her how we want the isolation to be, without having to worry about the costs of breaking any walls.
Bad thing is that none of us have any experience in isolating rooms. And since we don't know anything, I can't give a budget... Do any of you have experience in this, to maybe give some advice?

It'll be done in August, so there's time to plan!


And we both live in the Netherlands, if that would make any difference.


Yours,
Pianoman
