Well it has been awhile since I had visible progress.
But here are a few more pics of last springs
and this summer's additions.
1st is the older 'joined' rooms.
The one near the door is The Stone Room, a saltbox house tipped on end.
So 2 square corners and a triangle shaped opposing wall,
with door w/window and 2 window facing other booths
or control room.
This room will be finished with rough bread loaf stone,
like the drum room in the old Town House studio in London.
You know this sound from the drums in Phil Collin's In The Air Tonight.
Sadly that room was torn out.
To it's right, done with slab board facia is the
"Golden Triangle Room", based on Pythagorean's golden triangle dimensions.
5m X 4m X 3m with a ration of all three dimensions averaged
to give the rising height of the back roof point.
Each of these is going to have a different exterior and tile roof style.
Next is the seven sided drum or piano space on the opposite side.
It will be 5 windows plus a window double door
and exterior doubled double doors.
2.4 meters front and 4 meters at the peak.
It will be a very diffuse room allowing for a bigger sound that the space would normally have.
These are the 5cm steel random roof panel bracings.
which will be; aligned chip board, sheet rock and fiber board,
with RPG Skyline diffusers on down facing layer.

Top will be strong enough to walk on having 3 different weight layers and materials.
Another view. from across the floor at other booths doors.
I have computer calculated most possible sight lines
and put windows where needed. Subscribing to the Nashville,
get 'everyone playing together' philosophy,
which also works for jazz.
The roof line top of walls just below the trusses,
will have on end mounted versions of this diffuser prototype.
30cm X 30cm X 40cm boxes mounted on a light plywood sheet.

These will be on steel frame on end and angled 15° down all the way around the top of the large space.
Imagine being in a glade surrounded by hundreds of trees,
That is the main room sound I am going for.
thousands of randomized reflections of sound.
There will be two 5m tall rooms on either side, angled into the wall with the Thai style arc'd roof on top.
The steel and sheet rocks guys both shake their heads
about putting this one together...
Only one 90 degree corner and that will be damped.
One will be done with RPG Studio In A Box wall treatments,
Which I have from the last room, but don't need specifically.
and the other will double as a darkroom and and extra washroom/laundrey/toilet,
as well as being a tall isolation booth.
I can aim a amp cab upward and the sound will bounce back into an 180° off axis mic.
Depending on middle height wall treatment I can have it earlier or later reflections as I chose.
Both of these tall rooms bookend the view nicely.
DLD, Chili farmer. Plus bananas and papaya too.
Real happiness has no strings attached.
But pedal steels have many!
