Room treatments and acoustics…. How to begin?

Hello,

I have spent the past year and a half going to town. I have mindfully and exuberantly engaged with every aspect of my system, with one exception… acoustics and room treatments. 
 

I have a 14’x18’ x8’ high living room that is also my current listening room. I live in New York City, queens, and am an architectural designer with some fabrication ability. I am just beginning to get privy to how to approach acoustics and room treatments and find it fascinating. I would very much like to do the following:

-maximize the room acoustics in my living room, while maintaining or enhancing its visual appeal

-begin learning about acoustics as a whole, so that I may lean into designing architectural spaces intertwined with hifi listening..,, ie: large volume chamber woofers and open baffles incorporated into the architecture, even speakers partially or entirely cast into the floor walls or ceiling. 
 

how to begin? 

thanks for your insight and inspirations, fellow obsessives…!
