before i begin -- should i even do this project?

hello! i'm new to the forum and am looking for a little pre-pre-production advice. i'm an amateur musician and engineer, and i love writing / recording / mixing music with my friends. i also do a little sound design for local theater. i do all this in my house out of a spare bedroom (control room only). if i need to record -- that would mostly be vocals, plus some guitars and piano -- i set up mics in the house. the CR is 8' x 13'8" with 9'5" ceilings. i'm mostly happy with the acoustic aspects of my CR (currently hearing things very well and making the best mixes of my life). here are what i perceive are the downsides: 1. i'm out of space for new gear 2. the room isn't separately secured (see attached photos cr_front and cr_back to see some of the GIK and RealTraps treatment -- i also have treatment at the left/right mix positions and above the desk) last year, i dumped a crapload of money into my (rather moist) basement to control moisture and do repairs. there's a lot of space down there for moving my studio, which i would use as a single room. advantages include: 1. more room 2. would secure it with its own alarm system and CCTV 3. could do some tracking in it 4. could get all my gear in there (guitars, amps, keyboards and such are scattered throughout the house) 5. could fit more than one other person in it! the downsides: 1. moisture and seepage must be controlled 2. the ceilings are about 8' 3. probably couldn't get the same kind of symmetry i have in my current CR attached photo studio_outline shows the space as of last summer, just after the concrete was poured. since, the electrical has been cleaned up (brought above ceiling line) and the HVAC has been installed (supply and return run along left side of the beam). the red marks outline what i would consider to be studio space -- i.e. the studio would be at the far end of the photo, with its entrance at the lower-right red line. i reckon the outlined part is around 425 square feet. i am not concerned with isolation! i have neither the budget nor patience for that. i track rarely, i mix at a reasonable level, and my neighbors aren't even aware of the noise i'm making. i also already deal with all the incoming leakage in my current situation. Due to the moisture, i'm nearly certain i would have to raise the floor using a product like this Dricore subfloor. Despite all the waterproofing, drain tile installation and such that was done last summer, in my neighborhood seepage is a fact of life. My dehumidifier can keep the basement at 45%, and i would install a backup for that and for the sump pump. But i cannot trust all that enough to keep valuable gear right on the floor. I've read the warnings against floating a floor and I know that such a subfloor would not be ideal -- but how bad would it be and how manageable are the resulting acoustic problems? If i were to proceed, i would: 1. put in the subfloor, and finish it with something like cork 2. install a wall on top of that subfloor, along the red lines 3. clean up the walls A LOT 4. build a small machine room in some corner, and ensure it gets an HVAC return in there 5. run some dedicated electrical 6. stuff the ceiling with batt and staplegun a loose-weave fabric over it (alternate suggestions here most welcome) 7. use all the existing basstraps etc. I currently have and buy more 8. do the best i could at finding symmetry for my mix position 9. probably buy a RealTraps PVB for doing vocals 10. install a permanent dehumidifier and a battery backup for the sump pump 11. consider running some lines up the now-disused chimney to my upstairs "live room" I reckon a budget for items #1-6 would be $10-15k, which i think is doable if i go for "normal" construction and not worry about isolation. Given the problems with moisture, a slightly raised floor and a low ceiling -- is this a project even worth doing? Or should i just do the floor and make it my TV room?
