that's an old view of my house from google earth. The part in red is an empty mudroom 9 1/2 feet by 8 1/2 feet, the blue is my studio. (the room that the mudroom is off of is the living room). For a while this person
stored all the stuff we went to Florida to get last winter but now both are out of house/life. My studio has a door into the living room as well and as pics I posted before show I have floor monitors in the living room and I have my DAW connected to my living room stereo (coax digital) so the living room is also a nice 'live' room with enough space to move around.
Now that I have the mudroom back and we dont use that door for entry to the house anyhow I am moving my 4x12 and my 1x12 guitar cabs in there instead of relying on the iso cab it also lets me mic a cab with a large diaphragm condenser from a distance as well. It seems my studio is oozing out into the house, I'll doubt I'll ever need it but this room would be a good drum room too. The room has electric baseboard heaters but I dont use my electric heat, however by just cracking the door some the heat from the living room heats the mudroom (the living room is ridiculously hot compared to the rest of the house)
For decades I had just a corner of a room for my studio, now three rooms and there is a basement too underneath where either there or my two car garage a full band could jam (basement is also good for cabling). Makes me happy
