So I'm going to initiate some dialogue with my HOA and present it in the best light I can. I'm going to make some cheap yet attractive landscaping improvements along with the studio install, so it won't just look like I dropped a container on my property with no regard for aesthetics. I'll let you guys know how that goes (California can be pretty stupid when it comes to stuff like this.) If that doesn't work out, I have some potential nearby places where I can rent a parcel of land to put it on, within a short walking distance from my house, so I'll pursue that as plan B (although that brings with it added overhead, which is obviously best avoided.)
Upon closer inspection of the Spark1 Studio A design, I'm a bit put off by the surprisingly "ghetto" vibe of the desk (road rack on the desk, asymmetrical design, etc.), and the considerable distance between the listening position and the nicely soffit-mounted nearfields. I've already got a nice desk (
Studio RTA Producer's Station) and I'm definitely keen on incorporating it into my layout as a first priority. I'm using Auralex MoPads with my nearfields, so they are totally decoupled from the desk, and I've got all the rackspace I want with tons of room to grow as I get more gear (right now it's empty aside from my Firepod, Engl e530, Manley Elop, Urei LA-4, and Roland DC-30 Analog Chorus-Echo.)
What I'm likely to do is strive for more space and symmetry, with my desk near an end of the room with plenty of space for sound to travel behind it. I'm considering a single-room layout as a possibility, rather than trying to make a mix room and iso booth in one container. As long as the studio itself is isolated, I'm cool with wearing earplugs if I want to mic up something loud, I just want the room to sound good, and avoid comb filtering and standing waves like the plague. The dimensions of a 20 ft. cargo container present some challenges when working with the room ratios in the Gervais book. According to the best calculations I can figure from the layout pictures in the article, the Spark1 Studio A design was
not based on any of the recommended ratios in the book, so perhaps compromises were made for some reason. I'm still trying to arrive at something that even begins to make sense right now, and I may take this thread over to some studio builder forums.
