Double garage to studio - #1 Overview

I'm planning to convert our double garage into a sound studio.

This is my second attempt to get a functional room for recording and mixing (last attempt here)

Goal

My  goal is to have a good place for recording and mixing music, mostly for myself, one instrument at a time -e.g vocal, ac.guitar, percussion. But it should also work for a band with drums, or several people doing voice-over. Sound-isolation aim is 60db. It should also be a nice room to be in.

..edits to come :)

Building a small studio - The big halt

So, I've been planning my new sound-studio, converting part of our shed into a functional one room recording and mixing room. Then, realizing what needed to be done, things have come to a big halt - a musical G.P. (General Pause).

In order to get a good small studio-room in our shed I would have to:

• Redo the floor completely, making it concrete, leveled and with insulation and heating.
• Redo the outer wall completely.
• Build a room in the room (inner room)
• Redu most of the rafter-structure, possibly two new ridge beams.
• Replacing 90% of all studs
• Redo the roof with heavier sub-roof
• Redo the electrical completely
• And then all the inside-room acoustic taming and tweaking.

So, then it seems like less work to tear it all down and start from the bottom. And then, I might as well build something from scratch on another spot on our property.

So it's time to rethink the whole project..

Building a small studio - Part 3: Floor, walls and roof

In Part 2 I layed out the overall plan for my sound-studio.
In this post I'll go into the details for walls, roof and floor.

Floor

As it is, the floor is a divided in a section with concrete-slab (no: betong-såle) and a wooden construction on concrete poles.

Concrete-slab and wood

 My plan is this:

The acoustic underlay of 20mm is high-density floor-insulation (no: trinnlydsplater), like this.

Question: The plan for the floor is creating some treaple-leaf-effect. Is it good enough? Any other way to do this?
Qustion: Any alternatives for using the asphalt-plates? 
Isssue: It's not much space below the studs: I don't know how well I can stuff in the insulation, not to mention to put the asphalt-plates on.

Edit: I need to give the studio-floor a second thouht. Maybe it should be reflective and wood-based. Plywood maybe.

Walls

Walls are currently studs with "barn-clothing" (no: låvekledning).

My plan is this:

For the walls with door and window (east and west) I plan 2x4" studs with 10cm insulation for the inner walls. That's for easier installation of door and window.
For the two other walls I'm using 1,5x3" studs and 7cm insulation.

Roof

My plan for the walls applies for the inner roof as well (1,5x3" / 7cm) .

Building a small studio - Part 2: The plan

In Part1 I described how things are now.
In this post I'll try to formulate a plan for the new sound-studio, with pictures and drawings.

Note 1: This is plan version 1, and will probably change according to feedback from more experienced studio-builders and  knew insight along the way.
Note 2: Details about the plan will be posted in later posts.
See toc for overview.

General idea

My general idea is this:

3D-modell. Click for bigger image.

Front, from south

I'll make a double-wall construction for the sound-studio, 12,8 and 8,9/11,5cm wide, with a gap of 1cm. So that basically aplies for walls and roof. For the floor it's a floating (no: trinnlydspate) with insulation under.

This give me a space of 4,25m x 3,14 m and a hight of approx. 3,17m, in this shape:

Giving me a room-volume of .. (< 40m3)

My mixing-position will be facing north, with monitor-monitor-myhead making a triangle of 3 x 1,2m (approx)
