Hi Guys,
I am new to this forum have read a whole lot.
I record quite a bit at Kev's GURULAND. and that's how I know of John's designs. Everyone loves the rooms there.
I have moved house and my personal; Mix and Overdub room is having a reincarnation.
Here is the rough plan so far.
Existing building
The roof slopes downwards from North to south,
North High end is 3000mm
South Low end is 2100mm
(all the good outboard will go on the "high end" and the Behringer stuff will go on the "Low end")
{joke hah ha :lol: }
The room is a workshop area stuck on the side of the double brick garage. the door at the top leads into the garage.
The door on the left goes to the back yard. there is a double sash window on the south wall (yes at the bottom) which will be half blocked off and sealed and I will take advantage of some natural light.
The walls are single Brick and the roof is tile and the floor is Concrete.
Prerequisites:
A vocal booth positioned where someone could walk in and out of the control room without disturbing talent.
Fen Shui - Don't want my back facing door as I am working in the control room.
Stop traffic noise from semi-busy road 35 meters to the south. (occasional trucks using compression breaking)
Stop traffic rumble from highway 350meters to west
Wheel chair access (700mm wide)
Construction so far:
Bare rafters had Sarking (enviorosheild) stapled on and then 6mm MDF to seal it.
10mm plasterboard on all the brick walls stuck on with stud adhesive. All sealed airtight with flexible acrylic gap filler squeezed into good gaps same thickness as plasterboard.
I plan to build a free sanding frame with a 15mm gap between the 1st layer of plasterboard already mounted to the brick walls. The frame will be clad with two layers of 10 mm plasterboard. I know the air gap is small but i am being like one of my customers wanting too much for too little.
I suppose I could double that gap to 30mm.
NOW
in the rough image i have pointed areas where there is not much room for absorption.
in the north side the reflection from the left speaker on the hard (brick/plaster) surface on the right will bounce directly to me
and the reflection from the right speaker on the South hard surface will reflect to the couch...
What can I do in these small spaces to redirect or trap/apsorb . the further east you look the more room I have for adsorbing rock wool hangers etc.
So the main problem I feel is the areas of hard surfase just east (to the right) of my splayed surfaces adjacent to the speakers.
I am sure someone will hit a bomb shell that I haven't noticed yet.
Neibours
to the north there are neighbors about 10 meters away but there is a two car garage as an"air gap?".
to the east (right there is a footpath, side street then a house about 25 meters away diagonally adjacent (north east) and one in the opposite diagonal (south east) directly across the road is a double garage.
I normally mix quiet and remind myself to turn down often. sometimes I get carried away during the daytime during traffic noise etc. but at night I am very disciplined with my volume. So 100% isolation is not really necessary.
However if a small design change can help with minimal cost I will be happy to take advice.
Plan
Let's say I have a small budget, I already have heaps of rockwool and quite a few absorbers and the floor materials from the last studio (that I just moved out of)
The Room within the room will sit on hi density foam to decouple from the floor.
the floor will be also sitting on foam and will be 19mm (3/4") yellow tongue with the fake floorboards , the locking type 8mm thick. The floor will not touch the frame to aid in decoupling.
The speakers will be flush-mount/ Soffited.
The room will be mostly dead.
The gray dotted lines will be the absorptive walls I would like some guide as to where to Bass trap and where to put reflective surface to liven up a bit. The ceiling 2100mm high will be total absorptive 120mm rockwool with material over. The inside of the room in room's roof will be lined with 120mm rock wool and possibly have hangers in the cavity (remember the roof is angled roughly 3000 at tall end (north,top) and 2100 low end.
Please if you need more info please ask as many Q's as poss
AND keep in mind I am in a real hurry to finish as I have customers banging at the door and I basically have no income until, at least, the control room is finished as I have some recordings to mix and a couple of albums to finish....
It's a weird feeling having work but nowhere to do it.

I'm a little confused about the drawing as far as walls, but I'm going to answer you with questions :mrgreen:
Do you have rack gear? And where would it go.
Wouldn't it be better having the vocal booth along the north wall to get as much height out of it? (Assuming the north walls is north in the drawing)
Also I can't see the 2nd door?
What is the L, W, H?
Do you have sketch-up?
How do you get into the control room?
Is the green line representing the actual wall thinkness?
MMMmmmm I think thats it.
Hi Sorry,
The plan is nowhere near finished. there is a lot of detail to add in.
As I am pressed for time, each stage is getting drawn up at night after I complete a task.
I will uploads more images as I get there.
Yes the image is oriented at north being the TOP.
I have a small amount of rack gear that will sit under the console to the right or left and wont effect the plan. I prefer dead vocal booths so ceiling height at 2100 on the low end and 2400 on the high end will satisfy me. .I'm a little confused about the drawing as far as walls, but I'm going to answer you with questions :mrgreen: Do you have rack gear? And where would it go. Wouldn't it be better having the vocal booth along the north wall to get as much height out of it? (Assuming the north walls is north in the drawing)
In the North West corner on the west wall is the door that will be for access so the booth cant go in the north side.Also I can't see the 2nd door?
L = 5850 W= 2900 H(low end)= 2100 H(high end)=3000 Yes I do have a sketch up of the bare room - attachedWhat is the L, W, H? Do you have sketch-up?
Access to the control room is from the Right of the right speaker North there will be two doors one opening outwards and the other inwards. The green line is just the perimeter of the walls... again very rough sketchHow do you get into the control room? Is the green line representing the actual wall thinkness?
